July 21 (Reuters) - Wall Street's main indexes rose on Tuesday, as a steep rally in semiconductor shares helped shift the focus away from the latest Middle East hostilities and tariff battles, while investors looked ahead to major technology earnings reports for clues on the future of the AI trade.
Gains in recently battered semiconductor stocks provided huge support for the main U.S. stock indexes and the Philadelphia SE Semiconductor Index climbed 5.5%. The latter
is on track for its second consecutive advance after ending Friday more than 20% below its late-June record high, confirming a bear-market decline.
"Investors are really buying back in to the semis ahead of earnings because they have fear of missing out (FOMO), that these companies could report outsized earnings beats and increase their outlooks and they don't own as much as they did before the most recent pullback," said Lindsey Bell, chief investment strategist at 248 Ventures in Charlotte, North Carolina.
But Bell cautioned that when stocks rally sharply ahead of earnings, "it makes it more difficult for them to run in response to earnings."
"The numbers are going to be really good but the stocks are also priced for perfection," she said. The chip index dipped last week as investors grew concerned about high valuations and hefty investments on artificial intelligence. But even after that drop, it is still up nearly 75% year to date.
The Dow Jones Industrial Average rose 372.31 points, or 0.72%, to 52,211.57, the S&P 500 gained 65.40 points, or 0.88%, to 7,508.51 and the Nasdaq Composite gained 354.43 points, or 1.39%, to 25,862.50.
Among the benchmark's 11 major industry sectors, information technology led the gains with a more than 2% rise. The biggest decliner was consumer staples, down 0.9%.
Equity investors appeared to shrug off President Donald Trump's unveiling of 50% tariffs on a wide range of imports from Canada on Monday.
They also looked past geopolitics even as oil prices rallied more than 2%, hitting five-week highs. This was after two oil tankers carrying Saudi crude to Asia reversed course in the Red Sea after Yemen's Iran-aligned Houthis threatened to impose a blockade on commercial shipping there. Trump said the United States would respond if the Houthis followed through.
"Investors see (the war) as transitory because we know two things — that $100 oil is a pressure point for Trump, and we also know that midterm elections are coming up," Bell said.
Meanwhile, their focus this week will turn to results from Alphabet and chip makers Intel and Texas Instruments.
Among individual stocks, 3M shares gained 6.8% after the industrial giant lifted its full-year profit forecast. Hasbro shares rallied 7.7% after it raised annual revenue and profit forecasts, betting on demand for its digital gaming and "Magic: The Gathering" products.
Danaher shares sank 11.4% after the life sciences firm trimmed its core revenue growth outlook and reported weaker-than-expected revenue in its biotechnology business.
MSCI shares tumbled 9.9% after the index provider raised its full-year operating expense forecast despite better-than-expected quarterly revenue. Genuine Parts shares dropped 3.8% after the auto parts distributor lowered its full-year profit outlook.
Advancing issues outnumbered decliners by a 1.43-to-1 ratio on the New York Stock Exchange, where there were 84 new highs and 94 new lows. On the Nasdaq, 2,928 stocks rose and 1,790 fell as advancing issues outnumbered decliners by a 1.64-to-1 ratio.
The S&P 500 posted 9 new 52-week highs and 6 new lows while the Nasdaq Composite recorded 41 new highs and 103 new lows.
