AI Insider Summary

Sumedh S. Thakar, Qualys's CEO, shows an extremely high-frequency Form 4 record: 941 transactions since 2013, all selling, with 1,344,378 shares sold and zero bought. The recent sale prices trace a sharp rally: a large annual vesting event on February 3, 2026 was priced at $127.52, but by June 26, 2026 shares sold for just $120.47-$121.10 — before a rapid climb through June 29-30 ($125.60 to $140.00, sold in laddered 10,000-share tranches at $130, $135 and $140) and into July, when a single day's trading (July 14, 2026) saw eight separate sale tranches priced from $149.30 up to $163.565 as the stock kept rising through the session. That's roughly a 35% increase in Qualys shares between the June 26 low and the July 14 high, entirely visible through a systematic, price-laddered selling program.

A price-laddered selling structure

Rather than selling a fixed amount at a single price, Thakar's recent transactions show a clear laddered structure — selling in tranches across a range of prices, capturing a rising stock as it climbs rather than selling everything at once. June 30, 2026 shows exactly this: three 10,000-share tranches sold at $130.00, $135.00, and $140.00. July 14, 2026 extends the same approach across eight separate sales, from 100 to 1,570 shares each, priced from $149.30 up through $151.53, $155.30, $157.745, $160.8148, $161.6949, $162.40, and finally $163.565 — a single day's trading capturing the stock's rise in real time.
