Regime Signature.

Each instrument's behavioural texture sits in one of four quadrants — Grind-Up, Volatile-Up, Drift-Down, Volatile-Down — defined by two features computed over a rolling 63-day window: log-slope on close (positive → up, negative → down), and annualised realised volatility relative to the cross-sectional median. Continuation patterns (breakouts, momentum follow-through) work best in Grind-Up; mean- reversion plays work best in Drift-Down; both volatile quadrants punish naive participation.

The rule

For every instrument, compute over the trailing 63 trading days:

  • slope — per-bar slope of log(close) from a linear regression, annualised by ×252. The sign tells you trend direction.
  • realised volatility — standard deviation of daily log returns × √252.
  • up-day fraction — count of close_t > close_{t-1} divided by non-zero-return days.

Classification uses the slope sign and the vol vs. the cross-sectional median (so the quadrant is relative to the cohort, not absolute). Median across this universe today: 18.5%.

Grind-Up slope > 0 · vol < median
Volatile-Up slope > 0 · vol ≥ median
Drift-Down slope ≤ 0 · vol < median
Volatile-Down slope ≤ 0 · vol ≥ median

By quadrant

Grind-Up 6

Positive trend, below-median realised vol. Continuation patterns work best here.

  • XLV Health Care +59.9%
  • XLF Financials +52.7%
  • XLRE Real Estate +16.3%
  • XLU Utilities +8.0%
  • XLP Consumer Staples +7.9%
  • SPY S&P 500 ETF · Benchmark +6.6%
Volatile-Up 3

Positive trend but above-median vol. Continuation can work but stops get hit; size down or use wider stops.

  • XLI Industrials +27.3%
  • XLK Technology +7.6%
  • XLB Materials +0.4%
Drift-Down 0

Negative trend, below-median vol. Bounces tend to fade; mean-reversion shorts work better than trend-followers.

  • — none
Volatile-Down 3

Negative trend with above-median vol. Punishes both naive continuation and naive reversion; reduce activity.

  • XLE Energy -5.0%
  • XLY Consumer Discretionary -18.5%
  • XLC Communication Services -32.4%

Cross-read: stack Regime Signature against Sector RS (rankings) and Support Confluence (where the next support sits). A Volatile-Up name with no nearby support cluster is the riskiest combination; a Grind-Up name with a tight 3-horizon confluence below is the cleanest setup the framework currently produces.
