RMBS RAMBUS INC
Price Chart
Executive Summary
Two Rambus insiders — the EVP/COO and SVP/General Counsel — sold a combined $5.88M in open-market sales over a 5-day window. The EVP/COO's $5.74M sale represents ~0.04% of the $15.5B market cap, a trivial amount relative to company size. The sales are not clustered in a pattern suggesting 10b5-1 plans, but the dollar value is immaterial and insider sales are generally weak predictive signals.
