‘The most important stock on planet Earth,’ according to Goldman

Wall Street firm's trading desk says this one stock's earnings could shake up financial markets.

Nvidia Corp.’s earnings due Wednesday is such a big event in markets that Goldman Sachs Group Inc.’s trading desk has called it “the most important stock on planet earth.”

With options positioning implying about a 11% move in either direction, AI poster-child Nvidia could shake up financial markets given its influential weighting on indexes and crowded long positions in the stock. Just Nvidia alone has been responsible for one-third of the Nasdaq 100 Index’s gains this year.“Everyone is in the pool and there are positioning warning signs,” Goldman tactical specialist Scott Rubner wrote in a note to clients on Tuesday. “The bar is high, and by high I mean a big beat is expected.”Traders are bracing for more volatility after Nvidia tripled in value over the past year — pumped by an unrelenting artificial intelligence frenzy that’s propelled broader markets. Nerves are already running high, with the stock falling 4.4% on Tuesday, dragging megacap peers down with it.
