LXRX insider buying – Lexicon Pharmaceuticals, Inc.
45 insider purchases since 2016 worth $193.8M by 18 different insiders. Last 12 months: 4 purchases, $2.7M. Most recent filing: 2026-02-25.
Small company Public float $170M (latest 10-K, SEC). Share prices of small companies usually swing much more than those of large ones, in both directions, and are easier to move with little trading.
Same time range as the chart above - each mark sits under the week of the trade. Circles = purchases (height = price paid, size = amount), red triangles = open-market sales of $50k+. Prices as reported, not adjusted for later stock splits. 25 older purchases (before the 5-year window) are listed in the table below.
Purchases are open-market buys (SEC Form 4, code "P") - insiders paying with their own money. Sales are open-market sales (code "S") of $50,000 or more; many sales are pre-planned (Rule 10b5-1) or made for taxes and diversification. Each row links to the original filing.
