Does following Coherent Corp.’s insiders pay?
From February 17, 2010 to September 15, 2026, 31 insiders reported 12 open-market purchases and 195 sales not made under a pre-set plan in Coherent Corp. Twelve months after each purchase was reported, the shares were +14.9% against the S&P 500 on average (median +17.1%), over 12 purchases with a full year of prices; 75% beat the index. After sales, the shares moved +20.1% against the index over 12 months (a negative figure means selling was the right call). That rests on fewer than 20 purchases, too few to read much into. 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 12, 2011 into $76,591 by November 2, 2026, +14.3% a year. It held shares 41% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $30,917 (+7.7% a year), and held throughout $83,592 (+15.0%).
