See our latest analysis for Rambus. Rambus shares trade at US$127.05 after a small pullback over the past week. However, the 30 day share price return of 5.86% and 90 day gain of 24.62% sit alongside a very large 5 year total shareholder return of about 7x. This suggests momentum has been strong as investors factor in AI infrastructure products like the new PCIe 7.0 Switch IP, recent conference appearances, and mixed commentary around royalties and expenses.
