Director Robert Van Dyk bought 25,000 shares of CLBK at $10.00 on 2026-07-20; stock down -57.6% from 52-week high amid cluster buy activity by 3 other insiders in 14 days.
Director Robert Van Dyk purchased 25,000 shares at $10.00, raising his holdings to 322,013 shares, on a day when Columbia Financial stock has declined -57.6% from its 52-week high of $25.83. This buy coincides with a cluster pattern in which 3 other insiders also bought within the past 14 days, suggesting coordinated or synchronized action during a significant drawdown. However, the insider's track record provides caution: his prior buy at this same ticker returned -1.8% over 30 days and -4.7% over 90 days, representing a 0% win rate on his cross-ticker open-market history at the 90-day mark. The current price of $10.94 sits near the transaction price of $10.00, with the stock down -44.7% over the past 30 days, indicating the decline is recent and ongoing.
