Signal backtest
Do disclosed trades beat the market — and does the edge survive the disclosure lag? For each transaction we measure forward price return vs SPY from two entry points: the trade date (the insider's edge) and the filed date (what a subscriber could actually act on). Alpha = trade return − SPY return over the same window.
Median disclosure lag: 10 days — short enough that most of the edge is still capturable at filing.
Coverage: 473/2672 eligible trades priced (55% of disclosed $). The unpriced 45% are delisted/foreign/unresolved tickers, silently excluded — a survivorship bias that flatters the numbers below (names that went to zero can't report a forward return).
Mean alpha vs SPY (percentage points)
| Side | Basis | 1m | 3m | 6m | 12m | Hit-rate (3m) | n (3m) |
|---|---|---|---|---|---|---|---|
| buys | trade-date | +1.3 | +3.9 | +6.6 | +9.3 | 53% | 203 |
| filed-date | +1.4 | +3.8 | +6.6 | +10.5 | 55% | 196 | |
| sells | trade-date | -2.3 | -4.7 | -4.6 | -1.9 | 31% | 241 |
| filed-date | -2.0 | -2.5 | -2.4 | +1.7 | 41% | 229 |
Buys want positive alpha; sells want negative (they exited before under-performance). Hit-rate = share of buys beating SPY.

Signal = blended 3–12m buy alpha, shrunk toward 50 for small samples.
Method & limitations: forward price return (ex-dividends) over each horizon, equal-weighted per disclosed transaction (not $-weighted). Benchmarked against SPY over the identical window. Delisted/unpriceable tickers drop out (survivorship bias — flatters alpha). Hit-rates near 50% mean positive mean alpha is driven by a right-skewed subset of winners, not a consistent per-trade edge — a portfolio tilt, not a trade signal. A directional study, not a trading model.
