Warning Scoreboard

We don't predict prices. We flag overheating — every day we log the pool's strong crowding signals, then verify against actual prices 30 days later, fully public. The follow-through rate is this product's only advertising.

Warning log running45 days logged · 3923 crowding signals (2026 overheated ≥60, marked at real quotes). Reversal follow-through of expired overheat warnings: 36/311 (11.6%)

🔬 Engine self-check

Every call is baselined the moment it is made and judged automatically after 3 trading sessions · market-adjusted (excess vs SPY)

Direction accuracy51.3%95% CI 50% – 52.7% · n = 5138

The interval spans 50% — at this sample size it is statistically indistinguishable from a coin flip. Not yet evidence of skill. About 400 judged samples are needed to resolve a 5-point difference.

Overclaim rate · share that fell short of half the claim

The engine systematically overstates magnitude: the median move reaches only 10% of what it claimed. This measure is more robust than hit rate (continuous rather than binary) and maps directly to what we promise — how big the impact is.

Methodology

Crowding ≥60 logs an overheat warning; 30 days later we check whether price moved against the crowded side (crowded-long → down / crowded-short → up)

Why this yardstickBacktested on two non-overlapping windows (Feb–Jul 2026)

Out-of-sample · strong-call reversal (T+21)

72.5%

n=69 · excess return vs SPY +6.47%

In-sample · strong-call reversal (T+10)

74.0%

n=50 · excess return vs SPY +4.46%

Calls that news flow makes look 'obvious' systematically reverse within 2–4 weeks — mean reversion after attention-driven overreaction. Replicated in both independent windows, stronger at longer horizons. That's the statistical basis of the crowding warning: not that we can predict direction, but that overheating itself has a measurable tendency to reverse.

Limitations: both windows sit in 2026 (a single regime); observations cluster by news, so the effective sample is smaller than nominal; the numbers above are research results. The live verification on this page starts from scratch with the log above — it does not inherit the backtest.

Methodology: every day at 00:00 UTC we snapshot crowding for every stock in the pool; scores ≥40 are logged immutably; overheat warnings (≥60) are verified against actual closing prices at 30-day expiry. MVP uses absolute prices; the SPY-excess yardstick ships with the production version. For investment research only; not investment advice.
