Three top insiders at Astera Labs (CEO, COO, General Counsel) sold a combined $34.74M in open-market transactions over two days (May 18-19), with the COO alone accounting for $25.6M. This is the largest insider selling cluster at ALAB in the past 30 days, representing ~0.07% of the $49.3B market cap — a trivial proportion. The cluster is likely driven by liquidity/vesting events rather than a bearish signal, as the dollar amount is immaterial relative to company size and insider sales are weak predictors of future returns.
