Le-Quoc Alexis, Chief Technology Officer at Datadog (DDOG), has filed 263 Form 4 transactions since his insider reporting began, all in a single company. The pattern is one-sided: zero open-market purchases and $238.1 million in total open-market sales. The only acquisition value on record, $142,774, came from option exercises and grants, which are compensation mechanics rather than conviction buys.
The recent activity confirms the selling bias. On October 7, 2026, Alexis executed ten open-market sales of DDOG totaling roughly $14.7 million, with individual transactions ranging from $168,256 to $5.05 million. Two weeks earlier, on September 23, he sold another $10.4 million across eight trades, the largest being $5.53 million. A single sale on September 2 brought in $4.64 million. In the last two months alone, the selling total exceeds $29.7 million.
The Form 4 codes show no purchases in the recent window. The C and M entries on those same dates are derivative conversions and option exercises, which carry a value of zero and precede the sales. The S codes, which represent open-market sales, dominate every filing date. Alexis has not bought a single share of DDOG on the open market across his entire filing history, and the most recent 18 transactions are all sales.
