Nasdaq dips as chipmakers slide

The tech-laden Nasdaq dipped on Tuesday with chip stocks falling to more than two-week lows, while the benchmark S&P 500 was subdued as focus turned to the Federal Reserve's policy meeting.

Investor darling Nvidia fell 1.5 per cent after the company unveiled the Blackwell B200, an AI chip it says is up to 30 times faster than its previous chip. Some investors suggested the news was priced into the high-flying stock.

Nvidia, which has cornered 80 per cent of the AI chip market, is expected to provide more details on pricing at its presentation later in the day.

Fellow chipmakers such as Advanced Micro Devices, Marvell Technology and Intel shed between 2.3 per cent and 6.1 per cent , while the Philadelphia Semiconductor index dipped 2.1 per cent to its lowest since Feb. 29.

"It is profit taking from the Nvidia conference ... wherever Nvidia goes these chips are going," said Dennis Dick, a trader at Triple D Trading.

"They are getting hit hard today but let's put it in perspective, it's been a pretty good year for a lot of these stocks."

At 11:35 a.m. ET, the Dow Jones Industrial Average was up 203.55 points, or 0.52 per cent , at 38,993.98, the S&P 500 was up 2.21 points, or 0.04 per cent , at 5,151.63, and the Nasdaq Composite was down 42.25 points, or 0.26 per cent , at 16,061.19.

Four of the 11 major S&P 500 sectors were trading were lower, while Tesla and Meta Platforms eased more than 1 per cent each, lagging most megacap growth stocks.

Meanwhile, Dow outpaced its Wall Street peers, supported by gains in Home Depot and McDonald's.

All three major stock indexes finished higher in the previous session, with the Nasdaq bouncing back from two successive small weekly losses as growth stocks such as Alphabet and Tesla boosted the tech-heavy index.

Focus will remain on U.S. central bankers who are expected to hold rates steady at the end of their two-day meeting on Wednesday.

But, investors are concerned that their new economic projections may be a wild card.

"The 'dot plot', meanwhile, might show FOMC (Federal Open Market Committee) members' concerns that inflation remains higher than expected, and thus push forward rate cuts, until greater disinflation must be achieved," said Naomi Fink, global strategist at Nikko Asset Management.

Robust inflation data has pushed traders to pull back bets of the first rate cut coming in June to 59.4 per cent from 71 per cent at the start of last week, according to the CME FedWatch Tool.

Among other movers, crypto-exchange operator Coinbase Global and miners Riot Platforms and Marathon Digital Holdings shed between 4.8 per cent and 6.5 per cent , tracking the sharp slide in bitcoin.

AI server maker Super Micro Computer dropped 10.9 per cent after announcing that it will sell 2 million shares that could fetch about $2 billion.

Spire Global jumped 28.6 per cent after the company announced a collaboration with Nvidia for AI-driven weather prediction.

Advancing issues outnumbered decliners by a 1.50-to-1 ratio on the NYSE and by a 1.28-to-1 ratio on the Nasdaq.

The S&P index recorded 38 new 52-week highs and one new low, while the Nasdaq recorded 37 new highs and 83 new lows.
