Yang Rick has demonstrated a strong buying bias in recent SEC Form 4 filings, with $20 million in total purchases against just $27,627 in sales across 24 transactions involving three companies. The most significant activity occurred in February and March 2026, with a $15 million purchase of SGP shares on February 9 followed by two large KRRO acquisitions totaling $4.99 million on March 10. These purchases dwarf the minor sales activity, which was concentrated in NEUE during October 2025, where multiple small transactions—including sales of $6,075, $16,571, and $1,890—were offset by equal or slightly different values in derivative transactions coded as "X" (exempt) or "M" (market). The NEUE sales, while numerous, represented negligible value compared to the subsequent multi-million dollar acquisitions in SGP and KRRO. The pattern suggests a shift in focus toward these two holdings, with SGP accounting for 75% of the total buy value. The absence of any sales in SGP or KRRO—coupled with the derivative codes "P" for purchase and "C" for conversion in SGP's filings—indicates these positions were actively accumulated rather than acquired through corporate actions. The data shows a clear directional move toward building substantial stakes in these companies while winding down a previously more active trading relationship with NEUE.
