"portfolio_rationale": "The strategy focuses on high-conviction mean reversion setups. ZS_CFD.US is the best new candidate with a score of 72 and deep oversold metrics (-22.4% vs MA50), warranting a full fixed-size entry of $3000. Existing holdings RMV, FUTR, and BYIT show strong reversion scores (75, 70, 68) and are retained. Profitable positions ERA and TRST are held as no exit criteria are met. UKW is skipped to avoid overtrading given its lower score relative to ZS. Total gross exposure will be $24,000 (2.4x leverage), well within the 3.0x limit."

"portfolio_rationale": "The strategy focuses on high-conviction mean reversion setups. ZS_CFD.US is the best new candidate with a score of 72 and deep oversold metrics (-22.4% vs MA50), warranting a full fixed-size entry of $3000. Existing holdings RMV, FUTR, and BYIT show strong reversion scores (75, 70, 68) and are retained. Profitable positions ERA and TRST are held as no exit criteria are met. UKW is skipped to avoid overtrading given its lower score relative to ZS. Total gross exposure will be $24,000 (2.4x leverage), well within the 3.0x limit."
