Crowdstrike, Natera Executives Sell Tens of Millions in Stock

A cluster of insider stock sales surfaced in wire filings. Crowdstrike president Michael Sentonas sold $64.2 million in shares, by far the largest transaction. At Natera, CEO Steven Chapman sold $526,000 in common stock and president Solomon Moshkevich sold $1.24 million in shares. Spyre Therapeutics' chief legal officer separately sold $2.63 million in shares. Insider sales are routine and do not by themselves signal a view on a company's prospects — many executives sell on a pre-set schedule to diversify holdings or cover tax bills. But the size of the Crowdstrike sale, more than $64 million from one executive in a single disclosure, is large enough to draw attention even against that backdrop. None of the filings disclose whether the sales were made under 10b5-1 trading plans, which are set up in advance and are not driven by current material information. That detail would change how much weight investors should put on the timing.
