Nvidia suffers record $364b loss in market value as Wall St drops

Shares of AI heavyweight Nvidia tumbled 9.5 per cent on Tuesday (Sept 3) in the deepest ever single-day decline in market value for a US company, as investors softened their optimism about artificial intelligence in a broad market selloff following tepid economic data.

Nvidia lost US$279 billion (S$364 billion) in market capitalisation, a major indication that investors are becoming more cautious about emerging AI technology that has fuelled much of this year's stock market gains.

The PHLX chip index plummeted 7.75 per cent, its biggest one-day drop since 2020.

The latest jitters about AI come after Nvidia last Wednesday gave a quarterly forecast that failed to meet the lofty expectations of investors who have driven a dizzying rally in its stock.

"Such a massive amount of money has gone to tech and semiconductors in the last 12 months that the trade is completely skewed," said Todd Sohn, an ETF strategist at Strategas Securities.

Intel dropped nearly nine per cent after Reuters reported CEO Pat Gelsinger and key executives are expected to present a plan to the company's board of directors to slice off unnecessary businesses and revamp capital spending at the struggling chipmaker.

Worries about slow payoffs from hefty AI investments have dogged Wall Street's most valuable companies in recent weeks, with shares of Microsoft and Alphabet trading lower following their quarterly reports in July.

"Some recent research has questioned if the revenues from AI alone will eventually justify this wave of capital spending on it. When assessing AI capex by individual companies, investors must consider if they are making the best use of their balance sheets and capital," BlackRock strategists wrote in a client note on Tuesday.

At its July record high close, Nvidia had almost tripled in 2024. Its recent losses leave it up 118 per cent year to date.

Tuesday's weakness in chip stocks accompanied wide declines on Wall Street, with the Nasdaq dropping 3.3 per cent and the S&P 500 down 2.1 per cent.

Investors mostly expect the Federal Reserve to cut interest rates by 25 basis points in its Sept. 18 policy announcement, according to CME's FedWatch Tool.

However, minority expectations of a 50 basis point cut rose to 37 per cent from 30 per cent after data on Tuesday signalled activity in the manufacturing sector remains soft.

Investors will get a host of data on the labour market this week, culminating in Friday's key government payrolls report.

"There's concern about what the job numbers are going to show, about seasonality," warned Steve Sosnick, a market strategist at Interactive Brokers.

The chip index is now up 14 per cent in 2024, just under the S&P 500's 16 per cent gain.

Nvidia's record one-session loss in stock market value was greater than the US$232 billion decline suffered by Facebook-owner Meta Platforms on Feb 3, 2022, when the social media company issued a dismal forecast, according to LSEG data.

Following Nvidia's quarterly report last week, the mean analyst estimate for annual net income through January 2025 has climbed to US$70.35 billion from about US$68 billion ahead of last week's report.

Those increased earnings estimates, combined with Nvidia's share losses, have the chipmaker now trading at 34 times expected earnings, down from over 40 in June and in line with its two-year average.

Broadcom, another chipmaker that has benefited from the boom in AI computing, fell 6.2 per cent ahead of its quarterly report on Thursday.
