Does following Coastalsouth Bancshares, Inc.’s insiders pay?

From July 7, 2025 to August 31, 2026, 13 insiders reported 13 open-market purchases and 4 sales not made under a pre-set plan in Coastalsouth Bancshares, Inc. Twelve months after each purchase was reported, the shares were +0.6% against the S&P 500 on average (median +0.6%), over 12 purchases with a full year of prices; 100% beat the index. That rests on fewer than 20 purchases, too few to read much into.

It held shares 100% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $12,360 (+17.4% a year), and held throughout $12,360 (+17.4%).

Moves are the shares’ return including dividends minus the S&P 500’s, from the close on the first trading day after each report; the number of trades with a finished 12-month window is in brackets. Green means the trade went the insider’s way (a purchase ahead of the index, a sale followed by the shares trailing it). A trade reported both by a director or officer and by a fund or company they are linked to counts once here, under the person. Purchases count only where the share price actually traded was at least $5. These figures describe what the shares did, not why anyone traded. Insiders across all companies.
