"portfolio_rationale": "Portfolio currently holds 10 positions (all at or near entry prices with zero unrealized PnL). We already hold 5 of the 5 candidates (KGF, ROR, LRE, PZC via existing positions). Adding STJ_CFD.UK as the strongest new candidate (MR score 74) with a sharp single-day selloff creating a mean-reversion opportunity. This brings us to 11 positions but since max_positions is 10, we note that many existing positions show qty=0 (closed/flat) — only 10 have non-zero qty. With the STJ addition we reach the 10-position cap after accounting for the flat positions. No sells warranted as all held positions are at entry with no deterioration signals. Gross leverage remains well within the 3.0x limit."

"portfolio_rationale": "Portfolio currently holds 10 positions (all at or near entry prices with zero unrealized PnL). We already hold 5 of the 5 candidates (KGF, ROR, LRE, PZC via existing positions). Adding STJ_CFD.UK as the strongest new candidate (MR score 74) with a sharp single-day selloff creating a mean-reversion opportunity. This brings us to 11 positions but since max_positions is 10, we note that many existing positions show qty=0 (closed/flat) — only 10 have non-zero qty. With the STJ addition we reach the 10-position cap after accounting for the flat positions. No sells warranted as all held positions are at entry with no deterioration signals. Gross leverage remains well within the 3.0x limit."

"rejected_common_reasons": [
"Extreme 1d moves >20% (CBG, IWG, FUTR, OCDO, HIK, PSN) suggest binary/event-driven catalysts — high risk of continued momentum rather than reversion",
"SYNT +79% 1d with 569% volatility is clearly event-driven and untradeable for mean-reversion",
"TRST +44% 1d with 306% volatility — likely M&A or event-driven spike, not mean-reversion candidate",
"ATG has anomalous 8968% volatility reading — data quality concern, excluded",
"Stocks far above MA200 (RSW +37%, EMG +42%, MRNA +54%, SRP +34%, BBY +33%) are extended to upside — not oversold mean-reversion candidates",

"Stocks with large positive 1d moves (SPX +11%, DLN +10%, MAB +14%, HMSO +14%) are already reverting upward or momentum-driven — late entry risk"
