"portfolio_rationale": "The strategy identifies high-conviction mean reversion setups. THG and CRWD exhibit the highest scores (85 and 82) with extreme recent drops, warranting new entries. The current portfolio has 7 active positions; adding 2 brings the total to 9, well within the max_positions limit (10). Gross leverage will increase from ~2.1x to ~2.7x, staying below the 3.0x cap. Existing positions are held as they have not hit stop-loss levels or shown signs of exhaustion, adhering to the 'avoid overtrading' rule."

"portfolio_rationale": "The strategy identifies high-conviction mean reversion setups. THG and CRWD exhibit the highest scores (85 and 82) with extreme recent drops, warranting new entries. The current portfolio has 7 active positions; adding 2 brings the total to 9, well within the max_positions limit (10). Gross leverage will increase from ~2.1x to ~2.7x, staying below the 3.0x cap. Existing positions are held as they have not hit stop-loss levels or shown signs of exhaustion, adhering to the 'avoid overtrading' rule."
