"portfolio_rationale": "Selling two losing positions (WIX_CFD.UK and LTA_CFD.FR) that show weak momentum and no clear reversion catalyst, freeing capital for two high-conviction mean-reversion buys. IWG_CFD.UK (score 78) and AMCX_CFD.US (score 70) both show sharp single-day drops well below moving averages, fitting the classic overreaction pattern. Holding 15 existing positions where most are flat or profitable; ICG_CFD.UK and DPLM_CFD.UK already held and confirmed by candidate list. Portfolio remains within leverage and position limits."

"rejected_common_reasons": [
"VTY, FUTR, WIZZ, WLN: Extreme drops (-20% to -73%) suggest binary/event-driven moves, not clean mean-reversion setups",
"IHG: Anomalous data (-98% from MA200, 603% volatility) indicates data quality issue or corporate action",
"ADJ, CO, BIG: Penny stocks with extreme volatility (150-290%+), poor liquidity likely, not suitable",
"XRX: -55% from MA200 suggests structural decline, not mean-reversion candidate",
"WTB, DLN, HMSO, JDW, CRST: Large positive 1d moves (+10-25%) are momentum/breakout, wrong direction for mean-reversion long entry",
