Woo Raymond, Chief Technology Officer of Cerillion (CBLL), has been a consistent seller of company stock over the past several months, with no open-market purchases recorded in his recent Form 4 filings. Between February and May 2026, Raymond executed at least 13 open-market sales totaling roughly $795,000, with the largest single transaction occurring on May 1 at $135,195. The pattern is tightly coupled to option exercises and restricted stock awards: on each monthly sale date, Raymond simultaneously exercised options (coded M) and sold the resulting shares, a routine "exercise-and-sell" structure that generates cash while covering the exercise cost and tax obligations.
The transaction cadence is highly regular, clustering on the first trading day of each month—February 2, March 2, April 1, and May 1—with an additional smaller sale on February 23 and May 21. The dollar values are modest relative to typical insider activity, ranging from roughly $14,000 to $136,000 per sale, and the aggregate sell value across all 53 filings since his reporting history began stands at approximately $1.7 million. Notably, Raymond has recorded zero open-market purchases (code P) and zero acquisitions outside of compensatory grants (code A) and option exercises, meaning his only discretionary market activity is on the sell side.
The absence of any buying bias, combined with the mechanical monthly rhythm of exercise-and-sell transactions, suggests a systematic approach to monetizing equity compensation rather than opportunistic timing. The April 1 grant of two restricted stock awards (both valued at $0) replenished his holdings, yet within days he converted those shares into cash through the standard exercise-and-sell pipeline. While the selling pressure is persistent, the transaction sizes are small enough that they likely represent routine portfolio diversification by a senior executive rather than a concentrated exit.
