About John Charles Thomas's insider trades
John Charles Thomas is EVP, General Counsel at Krystal Biotech (KRYS). Since May 26, 2026, John has reported no open-market purchases and 1 sale worth $194K on SEC Form 4. In the last 12 months: 1 sale ($194K).
1 sale (100% of the value sold) was made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so it says little about how the insider sees the stock today.
How to read insider trades
Officers, directors and owners of more than 10% of a company must report trades in its stock on SEC Form 4, usually within two business days. Purchases with their own money are the stronger signal: insiders sell for many reasons (taxes, diversification, a house), but buy for one. See every KRYS insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
