Until then, here's the news moving the markets this week. Hey listeners, it's Saturday, May 30th. I'm Imani-Mauese for the Wall Street Journal. And this is what's news in markets. Our look at the biggest stock moves of the week and the news that drove them. Let's dive in. Stocks continued their historic march higher as Wall Street's appetite for AI showed few signs of slowing. All three major indexes ended the week at record highs, and the SMP has now risen nine consecutive weeks, the longest winning streak since 2023.

Investors are paying historically high prices relative to corporate earnings, a dynamic not seen since the dot-com boom. The last time investors were willing to pay these kinds of prices was around the market peak in 2000. So far, investors are still buying. The tech-heavy NASDAQ led the way, rising just under 2.4% for the week. The S&P 500 grew 1.4%, and the Dow increased 0.9%. The AI boom minted two new trillion-dollar companies this week. Shares in memory chip makers Micron and S.K. Heinex surged nearly 30% and 20% respectively, to cross the trillion-dollar valuation mark.

They're the latest editions, after Samsung joined one of the stock market's most exclusive clubs earlier this month. For years, memory chips were seen as a commodity business, the tech equivalent of selling gasoline, But investors are now treating chips as one of the most precious resources in the AI economy. In fact, the combined value of Samsung, S.K. Heinex, and Micron now exceeds the market value of the world's three largest oil companies. Every AI model needs enormous amounts of memory to store and move data, creating a global shortage of semiconductors. According to data provider Orne, spot prices for a common AI memory chip known as DDR5 have more than doubled since November. stock prices have mirrored those gains.

Micron shares have tripled since the end of March, helping it become the fastest company to ever go from a $500 billion dollar valuation to a trillion dollar one. As memory chips become the hottest commodity, oil stocks are getting the cold shoulder. Energy was the worst performing sector in the S&P 500 this week, as crude prices saw their biggest monthly decline since the onset of the pandemic. Reports that Washington and Tehran may be inching toward a possible agreement that would reopen the straightover moves, have traders unwinding bets

that the conflict could lead to a prolonged supply shock. Investors have gotten used to whipsawing headlines as tensions in the Middle East drag on, but they still have some impact. The S&P Energy Index fell more than 5% over the week, as Brent Crude slid 11% to $92.5 a barrel. But don't cry for oil investors just yet. The conflict in the Middle East sent energy stock soaring earlier this year,

and the S&P Energy Index remains up more than $25. percent year-to-date. Ford was one of the week's biggest winners, as investors' enthusiasm for a new subsidiary continued to rev up. Shares in the automaker continued to climb nearly 17 percent this week following the company's announcement of an energy storage division called Ford Energy earlier this month. After pulling back from the electric vehicle market, Ford is repurposing batteries originally intended for EVs into stationary energy storage systems for AI data centers, power utilities, and industrial customers.

One Morgan Stanley analyst recently estimated that the business could eventually be worth $10 billion on its own. Investors see the move as a way for Ford to cash in on the AI frenzy, and that's right at a moment when the auto industry is slogging through an EB slowdown and broader downturn. Automakers are increasingly warning that new car sales could shrink this year. Roughly one million potential buyers have left the new car market since the start of the decade, and executives don't expect them back anytime soon, as consumers grapple with high interest rates,

stubborn inflation, and elevated gas prices. Board is up almost 27% for the year, while rival General Motors has risen by less than 4%. And now you know what's news in markets this week.
