Does following Greene County Bancorp Inc’s insiders pay?
From November 22, 2010 to June 15, 2026, 15 insiders reported 84 open-market purchases and 33 sales not made under a pre-set plan in Greene County Bancorp Inc. Twelve months after each purchase was reported, the shares were −3.2% against the S&P 500 on average (median −5.2%), over 73 purchases with a full year of prices; 45% beat the index. After sales, the shares moved −4.0% 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 6, 2015 into $66,098 by November 2, 2026, +17.9% a year. It held shares 99% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $43,974 (+13.8% a year), and held throughout $43,935 (+13.8%).
