          "reasoning": " The user wants me to act as an \"Arena strategy executor\" and perform a \"stage1_universe_scan\" for the EU region using the \"meanrev-v1\" strategy.\n\nKey constraints:\n- Output ONLY valid JSON\n- NO narrative\n- Do NOT invent prices, fundamentals, earnings dates, or sentiment\n- If a field is null/empty, treat it as unknown\n- Select exactly 5 candidates\n- Avoid earnings within 5 trading days (if known) - but all earnings data is null, so this constraint is moot\n- Avoid highly binary/event-driven moves (if known) - no news headlines or sentiment, so this is also moot based on provided data\n- Avoid sector concentration: max 1 per sector unless clearly justified (sector is empty for all, so this is also moot)\n- Target: short-term mean reversion in liquid equities\n- Horizon: 2-10 trading days\n\nThe strategy is mean reversion. I need to identify stocks that are likely to revert to their mean. Typically, this means:\n- Large moves away from moving averages (distance_from_ma200_pct, distance_from_ma50_pct)\n- High volatility might indicate potential for reversion\n- Large 1-day changes might indicate overreaction\n\nLet me analyze the data:\n\n**Key metrics for mean reversion:**\n- **distance_from_ma200_pct**: How far from the 200-day moving average. Large positive or negative values could indicate overextension.\n- **distance_from_ma50_pct**: How far from the 50-day moving average. More relevant for short-term reversion.\n- **change_1d_pct**: Large single-day moves could be overreactions.\n- **volatility_20d_pct**: Higher volatility might mean more potential for reversion, but also more risk.\n\n**Let me sort and analyze candidates:**\n\n**Extreme negative distance from MA50 (potential bounce candidates):**\n- WLN_CFD.FR: -76.24% from MA50 (huge!)\n- BYIT_CFD.UK: -14.35% from MA50\n- HIK_CFD.UK: -15.71% from MA50\n- IWG_CFD.UK: -22.14% from MA50\n- PNE3_CFD.DE: -15.53% from MA50\n- KGF_CFD.UK: -8.10% from MA50\n- EVD_CFD.DE: -5.46% from MA50\n- DOM_CFD.UK: 1.08% from MA50 (slightly above)\n- UTG_CFD.UK: -3.69% from MA50\n- INVP_CFD.UK: 9.57% from MA50\n- SPX_CFD.UK: 8.46% from MA50\n- BOY_CFD.UK: 18.64% from MA50 (overextended up)\n- RSW_CFD.UK: 14.33% from MA50 (overextended up)\n- EMG_CFD.UK: 15.52% from MA50 (overextended up)\n\n**Extreme positive distance from MA50 (potential pullback candidates):**\n- BOY_CFD.UK: +18.64%\n- RSW_CFD.UK: +14.33%\n- EMG_CFD.UK: +15.52%\n- INVP_CFD.UK: +9.57%\n\n**Large 1-day moves (potential overreaction):**\n- TRST_CFD.UK: +47.99% (huge!)\n- CBG_CFD.UK: -26.63% (huge!)\n- IWG_CFD.UK: -26.79% (huge!)\n- HIK_CFD.UK: -19.56%\n- KGF_CFD.UK: -16.59%\n- TESB_CFD.BE: -14.75%\n- PZC_CFD.UK: -13.86%\n- BYIT_CFD.UK: -12.67%\n- STJ_CFD.UK: -14.84%\n- RSW_CFD.UK: +18.16%\n- BOY_CFD.UK: +24.16%\n- SPX_CFD.UK: +10.91%\n\n**Extreme distance from MA200:**\n- WLN_CFD.FR: -87.36% (extreme!)\n- GXI_CFD.DE: -37.97%\n- HIK_CFD.UK: -28.88%\n- BYIT_CFD.UK: -28.03%\n- EVD_CFD.DE: -22.47%\n- IWG_CFD.UK: -17.65%\n- TESB_CFD.BE: -18.04%\n- BEN_CFD.FR: -18.53%\n- DOM_CFD.UK: -15.07%\n- CBG_CFD.UK: -13.37%\n- PNE3_CFD.DE: -36.33%\n\n**High volatility (could be good for mean reversion):**\n- CAR_CFD.US: 9367.60% (this seems like an error or extremely illiquid)\n- ATG_CFD.UK: 2871.93% (also seems erroneous)\n- TRST_CFD.UK: 305.13%\n- GXI_CFD.DE: 175.85%\n- CBG_CFD.UK: 169.06%\n- IWG_CFD.UK: 154.03%\n- RHIM_CFD.UK: 151.26%\n- HIK_CFD.UK: 155.60%\n- etc.\n\n**For mean reversion, I want:**\n1. Stocks that have moved significantly in one direction (large 1d change)\n2. Stocks that are far from their moving averages (especially MA50 for short-term)\n3. Reasonable volatility (not too low, but not extreme outliers that suggest data issues)\n\n**Let me identify the best candidates:**\n\n**Candidate 1: CBG_CFD.UK** - Close Brothers Group\n- change_1d_pct: -26.63% (massive drop)\n- distance_from_ma200_pct: -13.37%\n- distance_from_ma50_pct: -22.13% (very far below MA50)\n- volatility_20d_pct: 169.06% (high but not extreme outlier)\n- This looks like a classic mean reversion candidate - big drop, oversold relative to MA50\n\n**Candidate 2: IWG_CFD.UK** - IWG PLC\n- change_1d_pct: -26.79% (massive drop)\n- distance_from_ma200_pct: -17.65%\n- distance_from_ma50_pct: -22.14% (very far below MA50)\n- volatility_20d_pct: 154.03% (high)\n- Similar to CBG, big drop, oversold\n\n**Candidate 3: HIK_CFD.UK** - HIKMA PHARMACEUTICALS\n- change_1d_pct: -19.56% (big drop)\n- distance_from_ma200_pct: -28.88% (far below MA200)\n- distance_from_ma50_pct: -15.71% (far below MA50)\n- volatility_20d_pct: 155.60% (high)\n- Good mean reversion candidate\n\n**Candidate 4: KGF_CFD.UK** - KINGFISHER PLC\n- change_1d_pct: -16.59% (big drop)\n- distance_from_ma200_pct: 1.77% (near MA200)\n- distance_from_ma50_pct: -8.10% (below MA50)\n- volatility_20d_pct: 106.76% (reasonable)\n- Good candidate, though less extreme than others\n\n**Candidate 5: TRST_CFD.UK** - TRUSTPILOT AS\n- change_1d_pct: +47.99% (massive spike)\n- distance_from_ma200_pct: -5.71% (still below MA200)\n- distance_from_ma50_pct: +12.65% (above MA50)\n- volatility_20d_pct: 305.13% (very high)\n- This is a spike up, could revert down. But the volatility is extremely high, might be too risky.\n\n**Alternative candidates for the 5th slot:**\n\n**Alternative 5: STJ_CFD.UK** - ST JAMES'S PLACE\n- change_1d_pct: -14.84%\n- distance_from_ma200_pct: 4.63%\n- distance_from_ma50_pct: -6.67%\n- volatility_20d_pct: 125.87%\n- Decent candidate\n\n**Alternative 5: PZC_CFD.UK** - PZ CUSSONS\n- change_1d_pct: -13.86%\n- distance_from_ma200_pct: 2.98%\n- distance_from_ma50_pct: 2.59% (actually above MA50)\n- volatility_20d_pct: 92.73%\n- Not as strong, above MA50\n\n**Alternative 5: BYIT_CFD.UK** - BYTES TECHNOLOGY\n- change_1d_pct: -12.67%\n- distance_from_ma200_pct: -28.03%\n- distance_from_ma50_pct: -14.35%\n- volatility_20d_pct: 87.83%\n- Good candidate, similar to HIK\n\n**Alternative 5: TESB_CFD.BE** - TESSENDERLO CHEMIE\n- change_1d_pct: -14.75%\n- distance_from_ma200_pct: -18.04%\n- distance_from_ma50_pct: -19.35%\n- volatility_20d_pct: 105.77%\n- Good candidate\n\n**Alternative 5: EVD_CFD.DE** - CTS EVENTIM\n- change_1d_pct: +0.94% (small move)\n- distance_from_ma200_pct: -22.47%\n- distance_from_ma50_pct: -5.46%\n- volatility_20d_pct: 51.67%\n- Not a strong candidate due to small 1-day move\n\n**Alternative 5: PNE3_CFD.DE** - PNE AG\n- change_1d_pct: -7.29%\n- distance_from_ma200_pct: -36.33%\n- distance_from_ma50_pct: -15.53%\n- volatility_20d_pct: 80.95%\n- Good candidate, very oversold\n\n**Alternative 5: DOM_CFD.UK** - DOMINO'S PIZZA\n- change_1d_pct: -0.31% (small move)\n- distance_from_ma200_pct: -15.07%\n- distance_from_ma50_pct: +1.08% (slightly above)\n- volatility_20d_pct: 87.92%\n- Not a strong candidate\n\n**Alternative 5: ROR_CFD.UK** - ROTORK PLC\n- change_1d_pct: -7.82%\n- distance_from_ma200_pct: -3.44%\n- distance_from_ma50_pct: -7.47%\n- volatility_20d_pct: 114.54%\n- Decent candidate\n\n**Let me select the best 5:**\n\nI want a mix of:\n1. Clear oversold candidates (big drop, far below MA50)\n2. Different sectors (but sectors are unknown)\n3. Reasonable volatility levels (avoiding the most extreme outliers like CAR, ATG, WLN)\n\n**My final 5 selections:**\n\n1. **CBG_CFD.UK** - Close Brothers Group: -26.63% drop, -22.13% from MA50, high vol\n2. **IWG_CFD.UK** - IWG PLC: -26.79% drop, -22.14% from MA50, high vol\n3. **HIK_CFD.UK** - HIKMA PHARMACEUTICALS: -19.56% drop, -15.71% from MA50, high vol\n4. **KGF_CFD.UK** - KINGFISHER PLC: -16.59% drop, -8.10% from MA50, reasonable vol\n5. **BYIT_CFD.UK** - BYTES TECHNOLOGY: -12.67% drop, -14.35% from MA50, reasonable vol\n\nWait, let me reconsider. I should also consider some that are overextended to the upside for potential short reversion, but the strategy is likely looking for long positions on oversold stocks. The constraints say \"max 1 per sector unless clearly justified\" but sectors are all empty, so I can ignore that.\n\nLet me also consider TRST_CFD.UK but its volatility is extremely high (305%) and it had a +48% spike. This might be too risky or indicate a special situation.\n\nLet me check if there are any stocks that are overextended upward that could be short candidates:\n- BOY_CFD.UK: +24.16% day, +18.64% from MA50\n- RSW_CFD.UK: +18.16% day, +14.33% from MA50\n- EMG_CFD.UK: +15.52% from MA50\n\nBut the strategy seems to be about mean reversion in general, not just long positions. However, the typical approach is to buy oversold stocks. Let me focus on oversold candidates.\n\n**Revised selection focusing on strongest signals:**\n\n1. **CBG_CFD.UK** - Strongest signal: massive drop, far below MA50\n2. **IWG_CFD.UK** - Strongest signal: massive drop, far below MA50\n3. **HIK_CFD.UK** - Strong signal: big drop, far below both MAs\n4. **TESB_CFD.BE** - Good signal: big drop, far below both MAs (-18% from MA200, -19% from MA50)\n5. **PNE3_CFD.DE** - Good signal: oversold, -36% from MA200, -15% from MA50\n\nAlternatively:\n5. **BYIT_CFD.UK** - Good signal: -12.67% drop, -28% from MA200, -14% from MA50\n\nLet me compare TESB vs BYIT vs PNE3:\n- TESB: -14.75% day, -18.04% from MA200, -19.35% from MA50, vol 105.77%\n- BYIT: -12.67% day, -28.03% from MA200, -14.35% from MA50, vol 87.83%\n- PNE3: -7.29% day, -36.33% from MA200, -15.53% from MA50, vol 80.95%\n\nBYIT has the biggest distance from MA200 and a decent drop. PNE3 has the biggest distance from MA200 but smaller daily drop. TESB has the biggest distance from MA50 among these three.\n\nI think I'll go with:\n1. CBG_CFD.UK\n2. IWG_CFD.UK\n3. HIK_CFD.UK\n4. KGF_CFD.UK (for a slightly less extreme but still solid candidate)\n5. BYIT_CFD.UK (good combination of daily drop and distance from MAs)\n\nWait, I should also consider STJ_CFD.UK:\n- STJ: -14.84% day, +4.63% from MA200, -6.67% from MA50, vol 125.87%\n\nThis is also decent. But BYIT is more oversold relative to MA200.\n\nLet me finalize my 5:\n\n1. **CBG_CFD.UK** - Score: 95 - Massive drop, extremely oversold on MA50\n2. **IWG_CFD.UK** - Score: 94 - Massive drop, extremely oversold on MA50\n3. **HIK_CFD.UK** - Score: 90 - Big drop, very oversold on both MAs\n4. **BYIT_CFD.UK** - Score: 85 - Good drop, very oversold on MA200, moderately oversold on MA50\n5. **KGF_CFD.UK** - Score: 82 - Big drop, moderately oversold on MA50\n\nI should also consider TESB_CFD.BE as an alternative to KGF:\n- TESB: -14.75% day, -18.04% from MA200, -19.35% from MA50, vol 105.77%\n- KGF: -16.59% day, +1.77% from MA200, -8.10% from MA50, vol 106.76%\n\nTESB is more oversold on both MAs compared to KGF. So TESB might be better.\n\nLet me reconsider:\n1. CBG_CFD.UK\n2. IWG_CFD.UK\n3. HIK_CFD.UK\n4. TESB_CFD.BE\n5. BYIT_CFD.UK\n\nThis gives me a better mix. All are significantly oversold.\n\nNow I need to assign mean_reversion_scores (0-100) and short selection reasons.\n\n**Scoring logic:**\n- Larger negative 1-day change = higher score\n- Larger negative distance from MA50 = higher score\n- Reasonable volatility = higher score (too high is bad)\n- Distance from MA200 also considered\n\n**Calculating scores:**\n\n1. **CBG_CFD.UK**: \n   - change_1d_pct: -26.63% (excellent)\n   - distance_from_ma50_pct: -22.13% (excellent)\n   - volatility: 169% (high but acceptable)\n   - Score: 95\n\n2. **IWG_CFD.UK**:\n   - change_1d_pct: -26.79% (excellent)\n   - distance_from_ma50_pct: -22.14% (excellent)\n   - volatility: 154% (high but acceptable)\n   - Score: 94\n\n3. **HIK_CFD.UK**:\n   - change_1d_pct: -19.56% (very good)\n   - distance_from_ma50_pct: -15.71% (very good)\n   - distance_from_ma200_pct: -28.88% (excellent)\n   - volatility: 155% (high but acceptable)\n   - Score: 90\n\n4. **TESB_CFD.BE**:\n   - change_1d_pct: -14.75% (good)\n   - distance_from_ma50_pct: -19.35% (excellent)\n   - distance_from_ma200_pct: -18.04% (very good)\n   - volatility:",

Typically, this means:\n- Large moves away from moving averages (distance_from_ma200_pct, distance_from_ma50_pct)\n- High volatility might indicate potential for reversion\n- Large 1-day changes might indicate overreaction\n\nLet me analyze the data:\n\n**Key metrics for mean reversion:**\n- **distance_from_ma200_pct**: How far from the 200-day moving average. Large positive or negative values could indicate overextension.\n- **distance_from_ma50_pct**: How far from the 50-day moving average.

I need to identify stocks that are likely to revert to their mean. Typically, this means:\n- Large moves away from moving averages (distance_from_ma200_pct, distance_from_ma50_pct)\n- High volatility might indicate potential for reversion\n- Large 1-day changes might indicate overreaction\n\nLet me analyze the data:\n\n**Key metrics for mean reversion:**\n- **distance_from_ma200_pct**: How far from the 200-day moving average. Large positive or negative values could indicate overextension.\n- **distance_from_ma50_pct**: How far from the 50-day moving average. More relevant for short-term reversion.\n- **change_1d_pct**: Large single-day moves could be overreactions.\n- **volatility_20d_pct**: Higher volatility might mean more potential for reversion, but also more risk.\n\n**Let me sort and analyze candidates:**\n\n**Extreme negative distance from MA50 (potential bounce candidates):**\n- WLN_CFD.FR: -76.24% from MA50 (huge!)\n- BYIT_CFD.UK: -14.35% from MA50\n- HIK_CFD.UK: -15.71% from MA50\n- IWG_CFD.UK: -22.14% from MA50\n- PNE3_CFD.DE: -15.53% from MA50\n- KGF_CFD.UK: -8.10% from MA50\n- EVD_CFD.DE: -5.46% from MA50\n- DOM_CFD.UK: 1.08% from MA50 (slightly above)\n- UTG_CFD.UK: -3.69% from MA50\n- INVP_CFD.UK: 9.57% from MA50\n- SPX_CFD.UK: 8.46% from MA50\n- BOY_CFD.UK: 18.64% from MA50 (overextended up)\n- RSW_CFD.UK: 14.33% from MA50 (overextended up)\n- EMG_CFD.UK: 15.52% from MA50 (overextended up)\n\n**Extreme positive distance from MA50 (potential pullback candidates):**\n- BOY_CFD.UK: +18.64%\n- RSW_CFD.UK: +14.33%\n- EMG_CFD.UK: +15.52%\n- INVP_CFD.UK: +9.57%\n\n**Large 1-day moves (potential overreaction):**\n- TRST_CFD.UK: +47.99% (huge!)\n- CBG_CFD.UK: -26.63% (huge!)\n- IWG_CFD.UK: -26.79% (huge!)\n- HIK_CFD.UK: -19.56%\n- KGF_CFD.UK: -16.59%\n- TESB_CFD.BE: -14.75%\n- PZC_CFD.UK: -13.86%\n- BYIT_CFD.UK: -12.67%\n- STJ_CFD.UK: -14.84%\n- RSW_CFD.UK: +18.16%\n- BOY_CFD.UK: +24.16%\n- SPX_CFD.UK: +10.91%\n\n**Extreme distance from MA200:**\n- WLN_CFD.FR: -87.36% (extreme!)\n- GXI_CFD.DE: -37.97%\n- HIK_CFD.UK: -28.88%\n- BYIT_CFD.UK: -28.03%\n- EVD_CFD.DE: -22.47%\n- IWG_CFD.UK: -17.65%\n- TESB_CFD.BE: -18.04%\n- BEN_CFD.FR: -18.53%\n- DOM_CFD.UK: -15.07%\n- CBG_CFD.UK: -13.37%\n- PNE3_CFD.DE: -36.33%\n\n**High volatility (could be good for mean reversion):**\n- CAR_CFD.US: 9367.60% (this seems like an error or extremely illiquid)\n- ATG_CFD.UK: 2871.93% (also seems erroneous)\n- TRST_CFD.UK: 305.13%\n- GXI_CFD.DE: 175.85%\n- CBG_CFD.UK: 169.06%\n- IWG_CFD.UK: 154.03%\n- RHIM_CFD.UK: 151.26%\n- HIK_CFD.UK: 155.60%\n- etc.\n\n**For mean reversion, I want:**\n1. Stocks that have moved significantly in one direction (large 1d change)\n2. Stocks that are far from their moving averages (especially MA50 for short-term)\n3. Reasonable volatility (not too low, but not extreme outliers that suggest data issues)\n\n**Let me identify the best candidates:**\n\n**Candidate 1: CBG_CFD.UK** - Close Brothers Group\n- change_1d_pct: -26.63% (massive drop)\n- distance_from_ma200_pct: -13.37%\n- distance_from_ma50_pct: -22.13% (very far below MA50)\n- volatility_20d_pct: 169.06% (high but not extreme outlier)\n- This looks like a classic mean reversion candidate - big drop, oversold relative to MA50\n\n**Candidate 2: IWG_CFD.UK** - IWG PLC\n- change_1d_pct: -26.79% (massive drop)\n- distance_from_ma200_pct: -17.65%\n- distance_from_ma50_pct: -22.14% (very far below MA50)\n- volatility_20d_pct: 154.03% (high)\n- Similar to CBG, big drop, oversold\n\n**Candidate 3: HIK_CFD.UK** - HIKMA PHARMACEUTICALS\n- change_1d_pct: -19.56% (big drop)\n- distance_from_ma200_pct: -28.88% (far below MA200)\n- distance_from_ma50_pct: -15.71% (far below MA50)\n- volatility_20d_pct: 155.60% (high)\n- Good mean reversion candidate\n\n**Candidate 4: KGF_CFD.UK** - KINGFISHER PLC\n- change_1d_pct: -16.59% (big drop)\n- distance_from_ma200_pct: 1.77% (near MA200)\n- distance_from_ma50_pct: -8.10% (below MA50)\n- volatility_20d_pct: 106.76% (reasonable)\n- Good candidate, though less extreme than others\n\n**Candidate 5: TRST_CFD.UK** - TRUSTPILOT AS\n- change_1d_pct: +47.99% (massive spike)\n- distance_from_ma200_pct: -5.71% (still below MA200)\n- distance_from_ma50_pct: +12.65% (above MA50)\n- volatility_20d_pct: 305.13% (very high)\n- This is a spike up, could revert down. But the volatility is extremely high, might be too risky.\n\n**Alternative candidates for the 5th slot:**\n\n**Alternative 5: STJ_CFD.UK** - ST JAMES'S PLACE\n- change_1d_pct: -14.84%\n- distance_from_ma200_pct: 4.63%\n- distance_from_ma50_pct: -6.67%\n- volatility_20d_pct: 125.87%\n- Decent candidate\n\n**Alternative 5: PZC_CFD.UK** - PZ CUSSONS\n- change_1d_pct: -13.86%\n- distance_from_ma200_pct: 2.98%\n- distance_from_ma50_pct: 2.59% (actually above MA50)\n- volatility_20d_pct: 92.73%\n- Not as strong, above MA50\n\n**Alternative 5: BYIT_CFD.UK** - BYTES TECHNOLOGY\n- change_1d_pct: -12.67%\n- distance_from_ma200_pct: -28.03%\n- distance_from_ma50_pct: -14.35%\n- volatility_20d_pct: 87.83%\n- Good candidate, similar to HIK\n\n**Alternative 5: TESB_CFD.BE** - TESSENDERLO CHEMIE\n- change_1d_pct: -14.75%\n- distance_from_ma200_pct: -18.04%\n- distance_from_ma50_pct: -19.35%\n- volatility_20d_pct: 105.77%\n- Good candidate\n\n**Alternative 5: EVD_CFD.DE** - CTS EVENTIM\n- change_1d_pct: +0.94% (small move)\n- distance_from_ma200_pct: -22.47%\n- distance_from_ma50_pct: -5.46%\n- volatility_20d_pct: 51.67%\n- Not a strong candidate due to small 1-day move\n\n**Alternative 5: PNE3_CFD.DE** - PNE AG\n- change_1d_pct: -7.29%\n- distance_from_ma200_pct: -36.33%\n- distance_from_ma50_pct: -15.53%\n- volatility_20d_pct: 80.95%\n- Good candidate, very oversold\n\n**Alternative 5: DOM_CFD.UK** - DOMINO'S PIZZA\n- change_1d_pct: -0.31% (small move)\n- distance_from_ma200_pct: -15.07%\n- distance_from_ma50_pct: +1.08% (slightly above)\n- volatility_20d_pct: 87.92%\n- Not a strong candidate\n\n**Alternative 5: ROR_CFD.UK** - ROTORK PLC\n- change_1d_pct: -7.82%\n- distance_from_ma200_pct: -3.44%\n- distance_from_ma50_pct: -7.47%\n- volatility_20d_pct: 114.54%\n- Decent candidate\n\n**Let me select the best 5:**\n\nI want a mix of:\n1. Clear oversold candidates (big drop, far below MA50)\n2. Different sectors (but sectors are unknown)\n3. Reasonable volatility levels (avoiding the most extreme outliers like CAR, ATG, WLN)\n\n**My final 5 selections:**\n\n1. **CBG_CFD.UK** - Close Brothers Group: -26.63% drop, -22.13% from MA50, high vol\n2. **IWG_CFD.UK** - IWG PLC: -26.79% drop, -22.14% from MA50, high vol\n3. **HIK_CFD.UK** - HIKMA PHARMACEUTICALS: -19.56% drop, -15.71% from MA50, high vol\n4. **KGF_CFD.UK** - KINGFISHER PLC: -16.59% drop, -8.10% from MA50, reasonable vol\n5. **BYIT_CFD.UK** - BYTES TECHNOLOGY: -12.67% drop, -14.35% from MA50, reasonable vol\n\nWait, let me reconsider. I should also consider some that are overextended to the upside for potential short reversion, but the strategy is likely looking for long positions on oversold stocks. The constraints say \"max 1 per sector unless clearly justified\" but sectors are all empty, so I can ignore that.\n\nLet me also consider TRST_CFD.UK but its volatility is extremely high (305%) and it had a +48% spike. This might be too risky or indicate a special situation.\n\nLet me check if there are any stocks that are overextended upward that could be short candidates:\n- BOY_CFD.UK: +24.16% day, +18.64% from MA50\n- RSW_CFD.UK: +18.16% day, +14.33% from MA50\n- EMG_CFD.UK: +15.52% from MA50\n\nBut the strategy seems to be about mean reversion in general, not just long positions. However, the typical approach is to buy oversold stocks. Let me focus on oversold candidates.\n\n**Revised selection focusing on strongest signals:**\n\n1. **CBG_CFD.UK** - Strongest signal: massive drop, far below MA50\n2. **IWG_CFD.UK** - Strongest signal: massive drop, far below MA50\n3. **HIK_CFD.UK** - Strong signal: big drop, far below both MAs\n4. **TESB_CFD.BE** - Good signal: big drop, far below both MAs (-18% from MA200, -19% from MA50)\n5. **PNE3_CFD.DE** - Good signal: oversold, -36% from MA200, -15% from MA50\n\nAlternatively:\n5. **BYIT_CFD.UK** - Good signal: -12.67% drop, -28% from MA200, -14% from MA50\n\nLet me compare TESB vs BYIT vs PNE3:\n- TESB: -14.75% day, -18.04% from MA200, -19.35% from MA50, vol 105.77%\n- BYIT: -12.67% day, -28.03% from MA200, -14.35% from MA50, vol 87.83%\n- PNE3: -7.29% day, -36.33% from MA200, -15.53% from MA50, vol 80.95%\n\nBYIT has the biggest distance from MA200 and a decent drop. PNE3 has the biggest distance from MA200 but smaller daily drop. TESB has the biggest distance from MA50 among these three.\n\nI think I'll go with:\n1. CBG_CFD.UK\n2. IWG_CFD.UK\n3. HIK_CFD.UK\n4. KGF_CFD.UK (for a slightly less extreme but still solid candidate)\n5. BYIT_CFD.UK (good combination of daily drop and distance from MAs)\n\nWait, I should also consider STJ_CFD.UK:\n- STJ: -14.84% day, +4.63% from MA200, -6.67% from MA50, vol 125.87%\n\nThis is also decent. But BYIT is more oversold relative to MA200.\n\nLet me finalize my 5:\n\n1. **CBG_CFD.UK** - Score: 95 - Massive drop, extremely oversold on MA50\n2. **IWG_CFD.UK** - Score: 94 - Massive drop, extremely oversold on MA50\n3. **HIK_CFD.UK** - Score: 90 - Big drop, very oversold on both MAs\n4. **BYIT_CFD.UK** - Score: 85 - Good drop, very oversold on MA200, moderately oversold on MA50\n5. **KGF_CFD.UK** - Score: 82 - Big drop, moderately oversold on MA50\n\nI should also consider TESB_CFD.BE as an alternative to KGF:\n- TESB: -14.75% day, -18.04% from MA200, -19.35% from MA50, vol 105.77%\n- KGF: -16.59% day, +1.77% from MA200, -8.10% from MA50, vol 106.76%\n\nTESB is more oversold on both MAs compared to KGF. So TESB might be better.\n\nLet me reconsider:\n1. CBG_CFD.UK\n2. IWG_CFD.UK\n3. HIK_CFD.UK\n4. TESB_CFD.BE\n5. BYIT_CFD.UK\n\nThis gives me a better mix. All are significantly oversold.\n\nNow I need to assign mean_reversion_scores (0-100) and short selection reasons.\n\n**Scoring logic:**\n- Larger negative 1-day change = higher score\n- Larger negative distance from MA50 = higher score\n- Reasonable volatility = higher score (too high is bad)\n- Distance from MA200 also considered\n\n**Calculating scores:**\n\n1. **CBG_CFD.UK**: \n   - change_1d_pct: -26.63% (excellent)\n   - distance_from_ma50_pct: -22.13% (excellent)\n   - volatility: 169% (high but acceptable)\n   - Score: 95\n\n2. **IWG_CFD.UK**:\n   - change_1d_pct: -26.79% (excellent)\n   - distance_from_ma50_pct: -22.14% (excellent)\n   - volatility: 154% (high but acceptable)\n   - Score: 94\n\n3. **HIK_CFD.UK**:\n   - change_1d_pct: -19.56% (very good)\n   - distance_from_ma50_pct: -15.71% (very good)\n   - distance_from_ma200_pct: -28.88% (excellent)\n   - volatility: 155% (high but acceptable)\n   - Score: 90\n\n4. **TESB_CFD.BE**:\n   - change_1d_pct: -14.75% (good)\n   - distance_from_ma50_pct: -19.35% (excellent)\n   - distance_from_ma200_pct: -18.04% (very good)\n   - volatility:",

I need to identify stocks that are likely to revert to their mean. Typically, this means:\n- Large moves away from moving averages (distance_from_ma200_pct, distance_from_ma50_pct)\n- High volatility might indicate potential for reversion\n- Large 1-day changes might indicate overreaction\n\nLet me analyze the data:\n\n**Key metrics for mean reversion:**\n- **distance_from_ma200_pct**: How far from the 200-day moving average. Large positive or negative values could indicate overextension.\n- **distance_from_ma50_pct**: How far from the 50-day moving average. More relevant for short-term reversion.\n- **change_1d_pct**: Large single-day moves could be overreactions.\n- **volatility_20d_pct**: Higher volatility might mean more potential for reversion, but also more risk.\n\n**Let me sort and analyze candidates:**\n\n**Extreme negative distance from MA50 (potential bounce candidates):**\n- WLN_CFD.FR: -76.24% from MA50 (huge!)\n- BYIT_CFD.UK: -14.35% from MA50\n- HIK_CFD.UK: -15.71% from MA50\n- IWG_CFD.UK: -22.14% from MA50\n- PNE3_CFD.DE: -15.53% from MA50\n- KGF_CFD.UK: -8.10% from MA50\n- EVD_CFD.DE: -5.46% from MA50\n- DOM_CFD.UK: 1.08% from MA50 (slightly above)\n- UTG_CFD.UK: -3.69% from MA50\n- INVP_CFD.UK: 9.57% from MA50\n- SPX_CFD.UK: 8.46% from MA50\n- BOY_CFD.UK: 18.64% from MA50 (overextended up)\n- RSW_CFD.UK: 14.33% from MA50 (overextended up)\n- EMG_CFD.UK: 15.52% from MA50 (overextended up)\n\n**Extreme positive distance from MA50 (potential pullback candidates):**\n- BOY_CFD.UK: +18.64%\n- RSW_CFD.UK: +14.33%\n- EMG_CFD.UK: +15.52%\n- INVP_CFD.UK: +9.57%\n\n**Large 1-day moves (potential overreaction):**\n- TRST_CFD.UK: +47.99% (huge!)\n- CBG_CFD.UK: -26.63% (huge!)\n- IWG_CFD.UK: -26.79% (huge!)\n- HIK_CFD.UK: -19.56%\n- KGF_CFD.UK: -16.59%\n- TESB_CFD.BE: -14.75%\n- PZC_CFD.UK: -13.86%\n- BYIT_CFD.UK: -12.67%\n- STJ_CFD.UK: -14.84%\n- RSW_CFD.UK: +18.16%\n- BOY_CFD.UK: +24.16%\n- SPX_CFD.UK: +10.91%\n\n**Extreme distance from MA200:**\n- WLN_CFD.FR: -87.36% (extreme!)\n- GXI_CFD.DE: -37.97%\n- HIK_CFD.UK: -28.88%\n- BYIT_CFD.UK: -28.03%\n- EVD_CFD.DE: -22.47%\n- IWG_CFD.UK: -17.65%\n- TESB_CFD.BE: -18.04%\n- BEN_CFD.FR: -18.53%\n- DOM_CFD.UK: -15.07%\n- CBG_CFD.UK: -13.37%\n- PNE3_CFD.DE: -36.33%\n\n**High volatility (could be good for mean reversion):**\n- CAR_CFD.US: 9367.60% (this seems like an error or extremely illiquid)\n- ATG_CFD.UK: 2871.93% (also seems erroneous)\n- TRST_CFD.UK: 305.13%\n- GXI_CFD.DE: 175.85%\n- CBG_CFD.UK: 169.06%\n- IWG_CFD.UK: 154.03%\n- RHIM_CFD.UK: 151.26%\n- HIK_CFD.UK: 155.60%\n- etc.\n\n**For mean reversion, I want:**\n1. Stocks that have moved significantly in one direction (large 1d change)\n2. Stocks that are far from their moving averages (especially MA50 for short-term)\n3. Reasonable volatility (not too low, but not extreme outliers that suggest data issues)\n\n**Let me identify the best candidates:**\n\n**Candidate 1: CBG_CFD.UK** - Close Brothers Group\n- change_1d_pct: -26.63% (massive drop)\n- distance_from_ma200_pct: -13.37%\n- distance_from_ma50_pct: -22.13% (very far below MA50)\n- volatility_20d_pct: 169.06% (high but not extreme outlier)\n- This looks like a classic mean reversion candidate - big drop, oversold relative to MA50\n\n**Candidate 2: IWG_CFD.UK** - IWG PLC\n- change_1d_pct: -26.79% (massive drop)\n- distance_from_ma200_pct: -17.65%\n- distance_from_ma50_pct: -22.14% (very far below MA50)\n- volatility_20d_pct: 154.03% (high)\n- Similar to CBG, big drop, oversold\n\n**Candidate 3: HIK_CFD.UK** - HIKMA PHARMACEUTICALS\n- change_1d_pct: -19.56% (big drop)\n- distance_from_ma200_pct: -28.88% (far below MA200)\n- distance_from_ma50_pct: -15.71% (far below MA50)\n- volatility_20d_pct: 155.60% (high)\n- Good mean reversion candidate\n\n**Candidate 4: KGF_CFD.UK** - KINGFISHER PLC\n- change_1d_pct: -16.59% (big drop)\n- distance_from_ma200_pct: 1.77% (near MA200)\n- distance_from_ma50_pct: -8.10% (below MA50)\n- volatility_20d_pct: 106.76% (reasonable)\n- Good candidate, though less extreme than others\n\n**Candidate 5: TRST_CFD.UK** - TRUSTPILOT AS\n- change_1d_pct: +47.99% (massive spike)\n- distance_from_ma200_pct: -5.71% (still below MA200)\n- distance_from_ma50_pct: +12.65% (above MA50)\n- volatility_20d_pct: 305.13% (very high)\n- This is a spike up, could revert down. But the volatility is extremely high, might be too risky.\n\n**Alternative candidates for the 5th slot:**\n\n**Alternative 5: STJ_CFD.UK** - ST JAMES'S PLACE\n- change_1d_pct: -14.84%\n- distance_from_ma200_pct: 4.63%\n- distance_from_ma50_pct: -6.67%\n- volatility_20d_pct: 125.87%\n- Decent candidate\n\n**Alternative 5: PZC_CFD.UK** - PZ CUSSONS\n- change_1d_pct: -13.86%\n- distance_from_ma200_pct: 2.98%\n- distance_from_ma50_pct: 2.59% (actually above MA50)\n- volatility_20d_pct: 92.73%\n- Not as strong, above MA50\n\n**Alternative 5: BYIT_CFD.UK** - BYTES TECHNOLOGY\n- change_1d_pct: -12.67%\n- distance_from_ma200_pct: -28.03%\n- distance_from_ma50_pct: -14.35%\n- volatility_20d_pct: 87.83%\n- Good candidate, similar to HIK\n\n**Alternative 5: TESB_CFD.BE** - TESSENDERLO CHEMIE\n- change_1d_pct: -14.75%\n- distance_from_ma200_pct: -18.04%\n- distance_from_ma50_pct: -19.35%\n- volatility_20d_pct: 105.77%\n- Good candidate\n\n**Alternative 5: EVD_CFD.DE** - CTS EVENTIM\n- change_1d_pct: +0.94% (small move)\n- distance_from_ma200_pct: -22.47%\n- distance_from_ma50_pct: -5.46%\n- volatility_20d_pct: 51.67%\n- Not a strong candidate due to small 1-day move\n\n**Alternative 5: PNE3_CFD.DE** - PNE AG\n- change_1d_pct: -7.29%\n- distance_from_ma200_pct: -36.33%\n- distance_from_ma50_pct: -15.53%\n- volatility_20d_pct: 80.95%\n- Good candidate, very oversold\n\n**Alternative 5: DOM_CFD.UK** - DOMINO'S PIZZA\n- change_1d_pct: -0.31% (small move)\n- distance_from_ma200_pct: -15.07%\n- distance_from_ma50_pct: +1.08% (slightly above)\n- volatility_20d_pct: 87.92%\n- Not a strong candidate\n\n**Alternative 5: ROR_CFD.UK** - ROTORK PLC\n- change_1d_pct: -7.82%\n- distance_from_ma200_pct: -3.44%\n- distance_from_ma50_pct: -7.47%\n- volatility_20d_pct: 114.54%\n- Decent candidate\n\n**Let me select the best 5:**\n\nI want a mix of:\n1. Clear oversold candidates (big drop, far below MA50)\n2. Different sectors (but sectors are unknown)\n3. Reasonable volatility levels (avoiding the most extreme outliers like CAR, ATG, WLN)\n\n**My final 5 selections:**\n\n1. **CBG_CFD.UK** - Close Brothers Group: -26.63% drop, -22.13% from MA50, high vol\n2. **IWG_CFD.UK** - IWG PLC: -26.79% drop, -22.14% from MA50, high vol\n3. **HIK_CFD.UK** - HIKMA PHARMACEUTICALS: -19.56% drop, -15.71% from MA50, high vol\n4. **KGF_CFD.UK** - KINGFISHER PLC: -16.59% drop, -8.10% from MA50, reasonable vol\n5. **BYIT_CFD.UK** - BYTES TECHNOLOGY: -12.67% drop, -14.35% from MA50, reasonable vol\n\nWait, let me reconsider. I should also consider some that are overextended to the upside for potential short reversion, but the strategy is likely looking for long positions on oversold stocks. The constraints say \"max 1 per sector unless clearly justified\" but sectors are all empty, so I can ignore that.\n\nLet me also consider TRST_CFD.UK but its volatility is extremely high (305%) and it had a +48% spike. This might be too risky or indicate a special situation.\n\nLet me check if there are any stocks that are overextended upward that could be short candidates:\n- BOY_CFD.UK: +24.16% day, +18.64% from MA50\n- RSW_CFD.UK: +18.16% day, +14.33% from MA50\n- EMG_CFD.UK: +15.52% from MA50\n\nBut the strategy seems to be about mean reversion in general, not just long positions. However, the typical approach is to buy oversold stocks. Let me focus on oversold candidates.\n\n**Revised selection focusing on strongest signals:**\n\n1. **CBG_CFD.UK** - Strongest signal: massive drop, far below MA50\n2. **IWG_CFD.UK** - Strongest signal: massive drop, far below MA50\n3. **HIK_CFD.UK** - Strong signal: big drop, far below both MAs\n4. **TESB_CFD.BE** - Good signal: big drop, far below both MAs (-18% from MA200, -19% from MA50)\n5. **PNE3_CFD.DE** - Good signal: oversold, -36% from MA200, -15% from MA50\n\nAlternatively:\n5. **BYIT_CFD.UK** - Good signal: -12.67% drop, -28% from MA200, -14% from MA50\n\nLet me compare TESB vs BYIT vs PNE3:\n- TESB: -14.75% day, -18.04% from MA200, -19.35% from MA50, vol 105.77%\n- BYIT: -12.67% day, -28.03% from MA200, -14.35% from MA50, vol 87.83%\n- PNE3: -7.29% day, -36.33% from MA200, -15.53% from MA50, vol 80.95%\n\nBYIT has the biggest distance from MA200 and a decent drop. PNE3 has the biggest distance from MA200 but smaller daily drop. TESB has the biggest distance from MA50 among these three.\n\nI think I'll go with:\n1. CBG_CFD.UK\n2. IWG_CFD.UK\n3. HIK_CFD.UK\n4. KGF_CFD.UK (for a slightly less extreme but still solid candidate)\n5. BYIT_CFD.UK (good combination of daily drop and distance from MAs)\n\nWait, I should also consider STJ_CFD.UK:\n- STJ: -14.84% day, +4.63% from MA200, -6.67% from MA50, vol 125.87%\n\nThis is also decent. But BYIT is more oversold relative to MA200.\n\nLet me finalize my 5:\n\n1. **CBG_CFD.UK** - Score: 95 - Massive drop, extremely oversold on MA50\n2. **IWG_CFD.UK** - Score: 94 - Massive drop, extremely oversold on MA50\n3. **HIK_CFD.UK** - Score: 90 - Big drop, very oversold on both MAs\n4. **BYIT_CFD.UK** - Score: 85 - Good drop, very oversold on MA200, moderately oversold on MA50\n5. **KGF_CFD.UK** - Score: 82 - Big drop, moderately oversold on MA50\n\nI should also consider TESB_CFD.BE as an alternative to KGF:\n- TESB: -14.75% day, -18.04% from MA200, -19.35% from MA50, vol 105.77%\n- KGF: -16.59% day, +1.77% from MA200, -8.10% from MA50, vol 106.76%\n\nTESB is more oversold on both MAs compared to KGF. So TESB might be better.\n\nLet me reconsider:\n1. CBG_CFD.UK\n2. IWG_CFD.UK\n3. HIK_CFD.UK\n4. TESB_CFD.BE\n5. BYIT_CFD.UK\n\nThis gives me a better mix. All are significantly oversold.\n\nNow I need to assign mean_reversion_scores (0-100) and short selection reasons.\n\n**Scoring logic:**\n- Larger negative 1-day change = higher score\n- Larger negative distance from MA50 = higher score\n- Reasonable volatility = higher score (too high is bad)\n- Distance from MA200 also considered\n\n**Calculating scores:**\n\n1. **CBG_CFD.UK**: \n   - change_1d_pct: -26.63% (excellent)\n   - distance_from_ma50_pct: -22.13% (excellent)\n   - volatility: 169% (high but acceptable)\n   - Score: 95\n\n2. **IWG_CFD.UK**:\n   - change_1d_pct: -26.79% (excellent)\n   - distance_from_ma50_pct: -22.14% (excellent)\n   - volatility: 154% (high but acceptable)\n   - Score: 94\n\n3. **HIK_CFD.UK**:\n   - change_1d_pct: -19.56% (very good)\n   - distance_from_ma50_pct: -15.71% (very good)\n   - distance_from_ma200_pct: -28.88% (excellent)\n   - volatility: 155% (high but acceptable)\n   - Score: 90\n\n4. **TESB_CFD.BE**:\n   - change_1d_pct: -14.75% (good)\n   - distance_from_ma50_pct: -19.35% (excellent)\n   - distance_from_ma200_pct: -18.04% (very good)\n   - volatility:",
