NBIX NEUROCRINE BIOSCIENCES INC
Price Chart
Executive Summary
Four NBIX C-suite insiders sold a total of $4.93M in open-market shares over a 7-day window, with the largest sales by the Chief Human Resources Officer ($2.20M) and Chief Scientific Officer ($1.76M). The cluster is entirely sell-side, with no open-market purchases, and all sales are accompanied by derivative exercises or tax-withholding transactions, suggesting a liquidity/vesting pattern rather than a coordinated bearish signal. At $4.93M, the cluster represents ~0.03% of NBIX's $16.6B market cap — a trivial proportion that does not warrant a bearish read.
