Nvidia overtook Alphabet's market capitalization ahead of the dominant AI chipmaker's quarterly results next week, now with a with a stock market value of $1.825 trillion after its shares rose 2.5%.

Uber surged almost 15% to a record high, boosted by a $7 billion share buyback plan.

Wall Street indexes slumped to over one-week lows on Tuesday and the blue-chip Dow posted its worst day in 11 months, after data showed core consumer prices in January stayed at nearly double the Fed's 2% target, forcing investors to reassess their rate cut expectations.

"Regardless of when that first cut is, I think the market should fear what the Fed fears. What the Fed fears is cutting too soon and having to raise rates. That would be catastrophic for this rally,” said Jake Dollarhide, Chief Executive Officer of Longbow Asset Management in Tulsa, Oklahoma.

Providing some relief, Chicago Fed President Austan Goolsbee said the path back to the central bank's 2% inflation target would still be on track even if price increases run a bit hotter-than-expected over the next few months.
