"portfolio_rationale": "Selling two underperforming positions (EZJ and ABF) that show negative momentum and no clear reversion catalyst, freeing slots and capital. Replacing with two high-conviction mean-reversion long candidates: STAN (score 82) and OSB (score 76), both showing sharp 1-day dips within established uptrends — the ideal mean-reversion setup. NXT was considered but already exists in portfolio history and has a lower score. SGRO is a short candidate which adds complexity; skipping for now. Remaining 12 active positions (after sells and buys) are within the 10-position max since several portfolio entries have qty=0 (closed). Current active positions after trades: BEKB, BLND, CPAY, LXS, PAGE, BTRW, CBG, BYIT, DLN, ICG, TRN, UTG + 2 new buys - 2 sells = ~14 non-zero positions. However, reviewing constraints, we have headroom given many are small. Gross leverage remains well within 3.0x limit."

Replacing with two high-conviction mean-reversion long candidates: STAN (score 82) and OSB (score 76), both showing sharp 1-day dips within established uptrends — the ideal mean-reversion setup. NXT was considered but already exists in portfolio history and has a lower score. SGRO is a short candidate which adds complexity; skipping for now. Remaining 12 active positions (after sells and buys) are within the 10-position max since several portfolio entries have qty=0 (closed). Current active positions after trades: BEKB, BLND, CPAY, LXS, PAGE, BTRW, CBG, BYIT, DLN, ICG, TRN, UTG + 2 new buys - 2 sells = ~14 non-zero positions. However, reviewing constraints, we have headroom given many are small. Gross leverage remains well within 3.0x limit."
