How this is computed

Trend regime uses the 200-day moving average — the same gate the IVEST core applies before holding leveraged exposure. Residual momentum strips the market-beta component from returns before ranking — the single-factor edition of the signal the IVEST live book actually allocates on (the live version adds multi-factor residualization and earnings features under CPCV validation). Trend persistence measures how consistently the name held its regime over the last quarter. Composite score = 30·(trend) + 25·(raw momentum pct) + 25·(residual momentum pct) + 20·(1 − volatility pct): fully transparent. Every number regenerates daily from raw prices — no analyst opinion in the loop.
