Repligen Jumps 12% This Week as June Investor Update Approaches

Repligen shares rallied over the last five sessions heading into the Memorial Day break, but the stock is still deep in the red for the year. Now investors are trying to figure out if last week’s move signals a shift or was just a quick bounce. Nasdaq had Monday, May 25, as a market holiday. Normal trading is 9:30 a.m. to 4 p.m. ET. Repligen finished Friday at $115.06, a gain of 1.49% for the session and up 11.85% over five days. Shares are still down 29.78% for 2026. U.S. markets reopen Tuesday, so that's where the stock stands for now.
