Moderna Inc (NASDAQ: MRNA) shares fell 9.01% to $215.20, marking a sharp reversal after a recent surge. The primary driver is profit taking following a significant rally driven by anticipation for upcoming cancer vaccine data.

What Happened

The stock gave back part of its recent gains as investors locked in profits. Shares had reached their highest close in a year on October 15, 2026, ending that session at $236.50. Over the past three months, the stock gained 282.6%, significantly outpacing the 4.1% return of the S&P 500. The selling pressure hit one of biotech’s hottest trades, with the stock that ran the furthest facing the heaviest selling. Ahead of the drop, Goldman Sachs analyst Salveen Richter raised the firm’s price target on Moderna to $137 from $120 while maintaining a Neutral rating. Investors are looking ahead to an October 24 presentation of detailed cancer trial results for a melanoma vaccine partnered with Merck.
