Track record
How this works
Points per stock, capped at 100: new SC 13D stake (5%+ owner) in the last 3 weeks +35; a sale, buyout or strategic-review report in the last 30 days +35; volume 3× normal +15 (5× +20); open-market insider buying in the last 30 days adds +10 (2+ insiders +20) to a stock that already has one of the other signals. Announced deals are left out.
The weights are a simple judgment call, not fitted to history. There isn't yet a clean record of how often these signals came before a deal, which is why the track record starts today rather than with a backtest.
