Stock market today: Dow, S&P 500, Nasdaq jump as chip stocks rebound, Iran and Israel exchange strikes

Bitcoin (BTC-USD) rebounded nearly 3% on Monday to hover above $63,000 as the overall market rose following last Friday’s steep sell-off.

Yahoo Finance’s Ines Ferré reports:

The world’s largest cryptocurrency was recovering from sharp losses incurred last week, when the token fell below $60,000, more than 50% below its October all-time high.

Over the past month, bitcoin has tumbled roughly 20%, with year-to-date losses exceeding 27%.

Bernstein analysts noted that bitcoin has seen significant weekly outflows from ETFs in the last four weeks. Furthermore, bitcoin inflows from treasury companies and ETFs year to date stand at around $12 billion, versus $60 billion last year.

But Bernstein’s Gautam Chhugani and his team pointed out that bitcoin tends to be cyclical, writing that the lower inflows don’t affect their long-term thesis that the token can be a store of value, or retain its worth over time.

The stock market has been on a tear, leading many investors to wonder if it’s all just one artificial intelligence-fueled bubble waiting to pop.

But there are reasons to think the stock market hasn’t yet hit the extremes of previous bubbles.

Yahoo Finance’s Brian Sozzi reports:

The run-up in the market in recent months has been breathtaking to say the very least. Prior to Friday’s steep pullback, the S&P 500 (^GSPC) had surged by 15% during the prior two months, a 99th percentile return relative to history dating back to 1980, according to new research from Goldman Sachs analyst Ben Snider.

“The strength of the recent rally alongside persistently strong AI momentum has generated a wave of client concern that stocks have moved ‘too far, too fast’ and are likely reflecting an unsustainable degree of investor euphoria,” Snider wrote.

Snider offered three charts that suggest that while the trading activity is feverish, it isn’t a mania destined to end badly for the bulls.

First, the number of initial public offerings (IPOs) remains below average and well below prior cycle peaks.

Oil prices crept back up on Monday morning after an exchange of fire between Israel and Iran on Sunday and Monday threatened to derail ongoing peace negotiations as the war hit its 100th day.

Iran launched a new wave of strikes against Israel in retaliation for Israeli strikes on Lebanon, and Israel also struck back at Iran. On Monday, Iran said it ended its latest volley of strikes as President Trump urged both sides to stop shooting after the biggest eruption in hostility in the region since April.

Brent crude (BZ=F), the international benchmark, rose 1% to $94 a barrel. West Texas Intermediate (CL=F), the US benchmark, rose 1% to $91 a barrel. Oil prices pared some steeper gains after President Trump spoke on the phone with Israeli Prime Minister Benjamin Netanyahu and after Trump said, “Israel and Iran must immediately stop ‘shooting.’“

The president stated that efforts at diplomacy between Israel and Iran are “proceeding” and that peace talks “should move quickly,” even as the two sides appear far apart on key wedge issues.

Marvell (MRVL) and Flex (FLEX) stocks rose on Monday morning after S&P Dow Jones Indices announced the two companies will join the S&P 500 index (^GSPC), replacing The Campbell’s Company (CPB) and Pool Corp (POOL).

Shares of Marvell, a custom chip provider, jumped nearly 9% on the announcement, while Flex stock gained 4%. S&P 500 inclusion usually leads to a short-term bump in share prices, as it attracts more passive investors.

Although Marvell shares pulled back sharply on Friday, falling 16%, the stock has been on an incredible run this year. It’s up 210% since the start of 2026, and Marvell’s market cap has risen to $230 billion.

Apple (AAPL) will host its annual Worldwide Developers Conference (WWDC) on Monday at its Cupertino, Calif., headquarters.

Yahoo Finance’s Daniel Howley takes a look at what investors can expect:

The event, Tim Cook’s last as CEO of the company, will serve as a kind of reboot of Apple’s AI strategy, which has lagged behind competing firms’ efforts to date.

The biggest news out of the show, which runs through June 12, will likely be the debut of Apple’s long-delayed, AI-infused version of Siri.

The digital assistant landed on iPhones with a good deal of fanfare in 2011 but has largely languished over the years. Siri’s deficiencies have become even clearer with the advent of generative AI models, chatbots, and, more recently, AI agents.

Apple initially announced a revamped AI version of its helper in 2024, but ran into issues getting it out the door.

Nvidia (NVDA) CEO Jensen Huang called a global tech stocks sell-off that began last week a buying opportunity, saying the buildout of artificial intelligence has just begun.

From Bloomberg:

South Korea’s benchmark Kospi (^KS11) Index tumbled on Monday after investors pulled back from AI bets that have fueled a global bull market in equities. US tech shares tumbled Friday on concerns over a possible interest-rate hike.

Huang, responding to questions during a trip to Seoul about how that selloff should be perceived, said the industry was still in the early stages of constructing infrastructure that will serve as the foundation of an AI-fueled future.

On Monday, Nvidia and SK Hynix (000660.KS) said they struck a multi-year agreement to design future generations of memory chips for AI, a win for a South Korean leader vying with Samsung Electronics Co. (005930.KS) in the red-hot arena. Stocks including SK Hynix pared losses after South Korean President Lee Jae Myung said Monday he believed the domestic market remained undervalued.

“We’re at the beginning of it, and whatever happened to the stock market, you should be very happy because now you can buy at a discount,” Huang said. “Everybody should be very excited,” he told reporters after meeting with SK Group Chairman Chey Tae-won in Seoul.
