Regeneron Pharmaceuticals, Inc. (REGN) closed at $804.03 on September 23, 2026, marking a gain of 0.73% over the prior 24 hours. The move extended a broader weekly advance, with shares up 3.93% over the past seven days.
Despite the recent upward momentum, REGN remains down 3.59% over the trailing 30-day period, reflecting some lingering pressure on the stock over a longer timeframe. The company's market capitalization stands at $82.18 billion.
The daily and weekly gains suggest a partial recovery from the month-long pullback, though the 30-day decline indicates the stock has yet to fully reclaim lost ground from earlier in the period.
