Merrywell Christopher, Senior Executive VP, has demonstrated a clear accumulation bias in Columbia Banking System, Inc. (COLB) over the past two years, with $2.8 million in total buys outweighing $768,861 in sales across 26 transactions. The most significant purchases occurred on February 25, 2025 ($599,990 and $199,979) and March 1, 2024 ($439,995 and $329,987), all coded as open market acquisitions (A). Recent activity continues this trend, with a $519,990 buy on February 18, 2026, and a $373,381 acquisition on February 2, 2026, supplemented by smaller periodic purchases like the $131,491 transaction on March 13, 2026. Sales have been comparatively modest and sporadic, primarily involving dispositions (D) and small option exercises (P), including a $105,450 sale on January 30, 2024.
Christopher’s trading pattern reveals concentrated, multi-year confidence in COLB, with purchases consistently exceeding sales in both frequency and dollar volume. The executive has maintained this accumulation posture into 2026, with seven buy transactions year-to-date totaling over $1.3 million, including the recent $51,752 and $91,894 acquisitions in early March. The absence of any sales in 2026 further reinforces the directional bias. Transaction codes indicate a mix of open market purchases (A), discretionary trades (F), and one merger-related acquisition (M), with no material disposals since early 2024. This activity suggests sustained, voluntary equity accumulation in a single holding.
