Does following Amtech Systems Inc’s insiders pay?
From January 6, 2010 to September 16, 2026, 19 insiders reported 73 open-market purchases and 55 sales not made under a pre-set plan in Amtech Systems Inc. Twelve months after each purchase was reported, the shares were −29.0% against the S&P 500 on average (median −43.3%), over 58 purchases with a full year of prices; 16% beat the index. After sales, the shares moved −31.7% 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 March 1, 2011 into $2,562 by November 2, 2026, −8.3% a year. It held shares 67% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $32,612 (+7.8% a year), and held throughout $76,117 (+13.8%).
