What you need to know today

Dow sinks 600 points
The Dow Jones Industrial Average suffered its worst day of the year, dropping over 600 points on Thursday. Boeing led the decline on the Dow. Despite reaching intraday record highs earlier, both the S&P 500 and the Nasdaq Composite ended the day in negative territory. Nvidia's blockbuster earnings and guidance failed to prop up markets, with more than 400 stocks on the S&P 500 trading lower. Treasury yields extended gains as the Fed delays rate cuts, while oil prices bounced back after a three-day decline.

Nvidia pops
Shares of Nvidia soared as much as 11% after the AI chipmaker's earnings that beat Wall Street's estimates. It also issued strong guidance as demand for its artificial intelligence accelerators remains robust. Shares passed $1,000 for the first time, reaching an all-time high of $1,063.20 during intraday trading, and are up about 111% this year. 

Musk disapproves China EV tariffs
Tesla CEO Elon Musk said he's not in favor of tariffs on Chinese electric vehicles, which were imposed last week by President Joe Biden. "Neither Tesla nor I asked for these tariffs," Musk said in response to a question from CNBC's Karen Tso. "Tesla competes quite well in the market in China with no tariffs and no preferential support. I'm in favor of no tariffs."

Boeing sinks
Shares of Boeing dropped 7.6% after CFO Brian West said the company would continue to burn through cash this year.  Delivery of new planes, a major source of revenue, will not improve in the second quarter. Boeing is facing a host of production issues related to safety concerns. The company burned through nearly $4 billion in cash in the first quarter and West believes that figure could be similar or "possibly a little worse" in the second quarter.

Asia-Pacific markets slide
Stocks in the Asia-Pacific region fell on Friday as investors assessed inflation data from Japan. The Nikkei 225 fell 1% as inflation slowed for the second straight month. While the Bank of Japan is under pressure to raise interest rates, inflation is expected to push higher in the coming months. South Korea's Kospi dropped 1% after a report said Samsung Electronics' new chip wasn't ready for Nvidia. Samsung shares fell 2.4%. Hong Kong's Hang Seng dipped 1.3%, mainland China's CSI 300 index declined 0.4%, and Australia's S&P/ASX 200 shed 1.1%. 

[PRO] What's next for Nvidia?
Wall Street analysts are revising their price targets for Nvidia upwards after its blowout earnings and guidance. Some had feared a slowdown in demand as Amazon and Microsoft wait for Nvidia's more powerful AI chips. Nvidia's decision to split its stock could provide more upside for investors.

The bottom line

Nvidia's blockbuster earnings and forecast couldn't stop Wall Street from taking a late dive. Nvidia held up well, its stock closing above $1,000, up 9% on the day after reassuring investors its sales of graphics chips that power artificial intelligence weren't a flash in the pan.

What comes next for Nvidia is a 10-for-1 stock split; Post-split shares will start trading on June 10. Stock split will help retail investors, put off by a share price of a thousand-plus dollars, to buy them at around $100. Nvidia shares are up more than 240% in the last 12 months.

CNBC's Ryan Ermey explains more on the psychology of the move and how the mechanism of the stock split works.

So what's freaking markets? According to the Charles Schwab Trader Sentiment Survey, the bullish outlook among traders fell to 46% from 53% in the second quarter.

"Traders began the year feeling pretty confident that the economy was improving and Fed rate cuts would be quick to follow," said James Kostulias, head of Trading Services at Charles Schwab. "But inflation concerns have jumped significantly."

Before the latest minutes from the Federal Reserve meeting, suggesting concern about stubborn inflation, some strategists had estimated the Fed could cut interest rates at least three times this year as prices cooled. Now, traders are lowering their expectations to just one reduction, possibly in September or November.

As the first-quarter earnings season winds down, investors are shifting their attention to geopolitical concerns.

"The Fed has been pretty clear that they're not going to cut rates, so you don't have this, 'Will they or won't they' [scenario] keeping everybody on edge. We are going to start to see a turn to some of this geopolitical stuff, whether it's elections or the two ongoing wars," said Melissa Brown, managing director of applied research at SimCorp.

While events such as the U.S. and UK elections don't necessarily result in economic impacts, they do increase uncertainty, Brown noted.

"People may go from saying 'I'm just going to buy now,' to, 'Look, I'm gonna wait and see the outcome of this before I decide to commit more money to market,'" Brown said. 

The Daily Open will be back on Tuesday as U.S. markets will be closed for Memorial Day on Monday.
