Chang Carmen

Chang Carmen’s recent SEC Form 4 filings reveal a strong buying bias, with $20.03 million in total purchases against just $31,347 in sales across 30 transactions involving three companies. The most notable activity centers on KRRO and SGP, with significant acquisitions in early 2026. On March 10, 2026, Carmen executed two large purchases of KRRO stock totaling nearly $5 million—$2.7 million and $2.3 million, respectively. Earlier, on February 9, 2026, a single $15 million purchase of SGP stood out amid several smaller transactions coded as grants or conversions with no reported value. Prior activity in October 2025 involved NEUE, where Carmen’s trades were more mixed but still skewed toward accumulation. While several transactions were coded as gifts or small-value adjustments, the only meaningful sales were two dispositions totaling $22,647, offset by minor acquisitions. The disparity between Carmen’s buying and selling—particularly the concentrated, high-value purchases in KRRO and SGP—suggests a sustained accumulation strategy in these holdings. The absence of material sales in these positions further underscores a directional commitment, though the nature of the transactions (such as the $15 million SGP purchase being coded as a "P" for open market or private buy) leaves room for further scrutiny as filings develop.
