Cluster buys

Companies where 3 or more different insiders bought shares on the open market within 30 days, from their Form 4s. One insider buying is common. Several at once is rarer. This is what the filings say, not a forecast: on its own, insider buying did not predict returns in our backtest.

19 clusters.
