Nvidia's post-earnings slide highlights key risk

Nvidia extended its recent slump last week, falling more than 15% over the five-day period despite stronger-than-expected fourth-quarter earnings and a robust demand outlook for its market-leading AI chips. 

Nvidia  (NVDA)  shares, one of the market's key sentiment lynchpins, have stagnated for much of the past six months, rising only 10% compared to an 8.2% gain for the Nasdaq, as investors pared bets on the chipmaker's ability to match its extraordinary revenue growth over the coming year, despite its commanding share of a key tech sector marketplace.
