MRNA December 220/240 call spread: defined rebound risk

Buy December $220 calls and sell $240 calls in very small size. January $240 calls recorded $19.98M of ask-side trading across three sessions, supporting a rebound toward the prior high. Shares remain above rising daily averages, but the rally is extended and broader flow is mixed. Rich option volatility and earnings or clinical headlines favor a spread over outright calls.
