Willdan Group, Inc. insider trading

Does following Willdan Group, Inc.’s insiders pay?

From May 25, 2010 to September 16, 2026, 28 insiders reported 36 open-market purchases and 181 sales not made under a pre-set plan in Willdan Group, Inc. Twelve months after each purchase was reported, the shares were +50.7% against the S&P 500 on average (median +32.1%), over 23 purchases with a full year of prices; 65% beat the index. After sales, the shares moved +15.1% 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 May 30, 2014 into $144,213 by November 2, 2026, +24.0% a year. It held shares 55% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $38,642 (+11.5% a year), and held throughout $48,367 (+13.6%).

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.
