Bain Capital Investors LLC and related entities: insider trades

Director, 10% owner at 7 companies we cover. No open-market purchases and 12 sales not made under a pre-set plan, reported from October 25, 2010 to November 12, 2025. Trades reported separately by several related funds or companies are counted once, under this name.

What happened after Bain Capital Investors LLC and related entities’s sales?

After their sales, the shares moved +27.4% against the index over 12 months on average (a negative figure means selling was the right call); 46% trailed it.

With 296 insiders tested, some will look skilled or unskilled by chance alone: when we replaced each insider’s stocks with random companies bought on the same days, about 5.7 cleared the bar ahead and 23.3 behind. One record on its own proves little.

“Average vs S&P 500” is the stock’s return including dividends minus the index’s over the same dates, from the close on the first trading day after the report, or from the close on the trade date. Only windows that have finished are counted. For sales, a negative figure means the stock lagged after it was sold, so selling was the right call (green). “Went the right way” is the share of purchases that beat the index, or of sales that trailed it. The t-statistic uses one average per year of reports, because one person’s trades bunch into the same stock and weeks, and needs trades in at least four different years; the p-value comes from the t distribution with that number of years (with four years, a t of 2 has p = 0.14). “Some evidence” means p under 5%, “strong evidence” p under 1% over at least six years.
