Ranked list of US corporate insiders (CEOs, CFOs, directors, and 10%+ owners) by their 12-month forward alpha versus SPY on open-market SEC Form 4 purchases. Each insider is scored on 3 years of matured trade history (purchases made ≥12 months ago, so every forward return has fully resolved). The default Veteran view requires at least 10 qualifying purchases so rankings reflect a meaningful sample, not a lucky-streak run of 3–9 trades. Only discretionary trades count — 10b5-1 planned trades are excluded. Last updated .

For every SEC Form 4 P-code purchase made by a US corporate insider in the lookback window, finshort measures the stock's total return over the next 12 months and subtracts SPY's total return over the same window — that's the trade's alpha. We then aggregate per insider:
Past performance is not indicative of future results. This is research content, not investment advice. See disclaimer.
For each open-market purchase, we measure how much the stock returned over the following 12 months and subtract SPY's return over the same window. A positive alpha means the trade beat the broad US market.
10b5-1 plans are pre-arranged trading schedules where the insider cannot react to new information at the time of execution. We exclude them so the leaderboard measures discretionary timing skill rather than scheduled flow.
The default Veteran tier requires at least 10 matured qualifying trades, matching the minimum sample size used in academic insider-trading studies (Cohen-Malloy-Pomorski use 10+). With fewer trades, a couple of lucky picks during a hot market period can dominate the average alpha and produce misleading rankings. The Emerging tier surfaces insiders with 3–9 qualifying trades — useful for spotting newer signals, but treat the rankings with appropriate skepticism.
Each filter selects how many years of matured trade history to score insiders on. A trade is "matured" once its 12-month forward return has fully resolved (i.e. the buy was made ≥12 months ago). For example, the 3Y view ranks insiders on every qualifying purchase made between roughly 1 and 4 years ago. We cap at 10 years so rankings stay actionable and don't mix too many market regimes.
The cache refreshes weekly. Forward returns only change as new trades mature past the 12-month window, so a higher cadence isn't necessary.
