From insiders' Form 4 filings with the SEC: open-market purchases and sales only (awards, option exercises and shares withheld for tax are excluded), combined to one line per insider per day. "Plan" marks trades the filing says were made under a pre-set Rule 10b5-1 trading plan, which are scheduled in advance. Price changes run from the close on the trade date; hover a figure for the change relative to the S&P 500. Past moves don't predict future ones.

Does following Verastem, Inc.’s insiders pay?

From December 20, 2012 to January 14, 2025, 19 insiders reported 57 open-market purchases and 13 sales not made under a pre-set plan in Verastem, Inc. Twelve months after each purchase was reported, the shares were −55.4% against the S&P 500 on average (median −57.7%), over 53 purchases with a full year of prices; 2% beat the index. After sales, the shares moved +7.8% against the index over 12 months (a negative figure means selling was the right call). Buying each purchase the day after it was reported, an equal amount each, held 12 months or until that insider reported a sale, would have turned $10,000 on December 21, 2012 into $420 by November 2, 2026, −20.5% a year. It held shares 35% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $21,241 (+5.6% a year), and held throughout $66,877 (+14.7%).

Moves are the shares’ return including dividends minus the S&P 500’s, from the close on the first trading day after each report; the number of trades with a finished 12-month window is in brackets. Green means the trade went the insider’s way (a purchase ahead of the index, a sale followed by the shares trailing it). A trade reported both by a director or officer and by a fund or company they are linked to counts once here, under the person. Purchases count only where the share price actually traded was at least $5. These figures describe what the shares did, not why anyone traded. Insiders across all companies.

October 31, 2018	5 buying	−35.2%	−68.5%	−93.9%

April 30, 2013	2 buying	+46.6%	−4.7%	−35.3%

Colours show whether the crowd was right: green when buyers were followed by a rise above the index, or sellers by a fall below it. Total returns from the month end; past patterns are not a forecast.
