COLUMN GROUP III GP, LP has demonstrated a balanced but active trading pattern across two primary holdings, TNYA and SRZN, with a slight net buying bias. Between December 2025 and February 2026, the firm executed 30 transactions totaling $5.98 million in buys and $5.93 million in sells. Its most significant activity centered on TNYA, where it conducted a series of sales in February 2026, including two large disposals on February 11 valued at $1.47 million and $1.30 million, followed by additional sales later in the month. In contrast, the firm accumulated SRZN shares earlier in the year, with purchases peaking on January 20 at $187,531 and $166,285, alongside smaller acquisitions throughout January. The data reveals a clear shift in strategy by late January, pivoting from steady SRZN accumulation to concentrated TNYA divestment. While the dollar values of buys and sells were nearly even overall, the timing suggests a rotation out of TNYA after holding positions through early 2026. Transaction sizes varied widely, from smaller sales under $100,000 to multimillion-dollar dispositions. The lack of overlapping buy-sell activity for either ticker indicates distinct phases of positioning rather than active trading within the same period. The filings reflect disciplined execution without erratic swings, though the concentrated selling in TNYA warrants attention given the scale relative to the firm’s total activity.
