The insider sales are too small relative to market cap to be a standalone signal. Monitor for any additional insider selling in the next 30 days—a larger cluster would amplify the bearish read from the Q2 EPS miss. The Q2 earnings miss and widened GAAP loss guidance are the more material events for ALKS stock direction.
Price Chart
Executive Summary
Two Alkermes insiders (EVP R&D/CMO and EVP/CLO) sold a combined $536K in open-market shares on August 3, 2026, one week after the company reported Q2 earnings that missed consensus EPS by a wide margin ($0.00 actual vs $0.29 expected). The sales follow option exercises by the CMO and appear to be liquidity-driven post-vesting, but the timing—immediately after a significant earnings miss and widened GAAP net loss guidance—raises caution. At $8.2B market cap, the $536K represents only ~0.007% of market cap, well below the 0.1% materiality threshold, making this a routine cluster in absolute dollar terms.
