Does following Prosperity Bancshares Inc’s insiders pay?
From February 24, 2010 to May 27, 2026, 23 insiders reported 32 open-market purchases and 77 sales not made under a pre-set plan in Prosperity Bancshares Inc. Twelve months after each purchase was reported, the shares were −3.4% against the S&P 500 on average (median −2.8%), over 32 purchases with a full year of prices; 44% beat the index. After sales, the shares moved −5.8% against the index over 12 months (a negative figure means selling was the right call).
