BCAX CEO Mazumdar sells 36.8K shares for $704.7K at $19.17; stock -0.8% from 52-week high but +32.8% in 30 days

Mazumdar, as Chief Executive Officer of Bicara Therapeutics, divested 36,766 shares for $704,657.16 at $19.17 on 2026-03-09, reducing holdings by 9.8% to 339,392 shares. The sale occurred near the 52-week high ($20.06), with the current price of $19.90 only 0.8% below that peak, while the stock has surged 32.8% over the past 30 days and 5.6% over 90 days. Notably, Mazumdar's cross-ticker track record shows a 100% well-timed rate across 1 prior sell (with a 90-day return of -17.9%), and this most recent sale at BCAX represents his second transaction at this ticker following a prior sell on 2025-11-24 that also showed negative 90-day returns. Against this backdrop, the company reported a net loss of $36.3M over its most recent full fiscal year, operating at an unprofitable level with a $1.1B market cap. The timing of the sale—executed at a price near historical highs following a sharp 30-day rally—in the context of sustained operating losses, suggests the insider found current valuations appropriate for partial exit.

Significance 6/10

CEO Claire Mazumdar sold 41,163 shares of BCAX at $18.86 on 2025-11-24 (41.2K shares, $776.4K); holds 309,892 shares post-transaction.

Claire Mazumdar, Chief Executive Officer of Bicara Therapeutics, sold 41,163 shares valued at $776,428.85, reducing her stake by 11.7% from 351,055 to 309,892 shares. This sale occurred at $18.86 per share while the company trades at $18.46 and remains significantly unprofitable with a net loss of $36,330,000.00 for its most recent fiscal year. The timing of the sale—at the higher end of the 52-week range and after a 53.6% run-up over 90 days—reflects a material reduction in the CEO's ownership concentration. Despite substantial remaining holdings at 309,892 shares, the nature and magnitude of this sale warrant monitoring given the company's loss position and the execution context.
