Does following WD 40 Co’s insiders pay?
From April 13, 2010 to August 14, 2026, 25 insiders reported 26 open-market purchases and 64 sales not made under a pre-set plan in WD 40 Co. Twelve months after each purchase was reported, the shares were +0.9% against the S&P 500 on average (median +2.9%), over 23 purchases with a full year of prices; 61% beat the index. After sales, the shares moved +6.2% 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 August 9, 2012 into $28,187 by November 2, 2026, +7.6% a year. It held shares 60% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $33,969 (+9.0% a year), and held throughout $68,761 (+14.6%).
