What stands out

Deere shares moved higher in premarket trade after the company tightened its annual net income range, Moderna pared gains after a late-stage melanoma vaccine success tied to Merck's Keytruda, and crypto-linked names jumped as Bitcoin's rally forced record short liquidations. The trio shows three ways markets move before the bell: guidance revisions, binary biotech trial news, and macro-driven speculative squeezes. For active investors, the episode is a clear reminder that headlines can reprice risk across sectors in a single premarket session.
