WSJ What’s News — March 21, 2026
Host: Hannah Aaron Lang

Overview

This episode of WSJ's "What’s News in Markets," hosted by Hannah Aaron Lang, recaps a turbulent week in the financial markets. Key themes include significant downturns for gold and gold-mining stocks, the market’s skeptical reaction to blowout earnings from Micron Technology, and a dramatic sell-off of Super Microcomputer shares following news of legal trouble for its co-founder. The episode also places these developments in the wider context of global uncertainty, especially around the ongoing war in Iran and its impacts on energy and inflation expectations.

Major Discussion Points & Insights

1. Market Mood & Macro Backdrop

Oil Front and Center:
- The war in Iran, now in its third week, has dominated market conversations. At the week’s start, optimism surfaced around potential international cooperation to reopen the Strait of Hormuz, which is crucial for global oil flows ([00:33]).
- By midweek, however, sentiment shifted as continued conflict and attacks on Middle Eastern energy infrastructure combined with central bank actions to dampen markets.
Federal Reserve and Interest Rates:
- The Fed left rates unchanged, as expected, but Chair Jerome Powell issued a warning about inflation risks tied to the war, calling the environment a "difficult situation," which disappointed investors ([01:38]).
- This statement led to a sharp reduction in expectations for rate cuts in 2026, further fueling caution.

2. Market Recap: Stock and Commodity Moves

U.S. Market Indices:
- The Dow and Nasdaq each fell 2.1%.
- The S&P 500 dropped 1.9% ([02:37]).
Oil Prices:
- Brent crude futures jumped 8.8% for the week.

3. Gold’s Sudden Decline

Performance:
- Gold logged its worst week since 2011, down 9.5%. It's fallen in seven of the past eight sessions.
- Gold mining companies were hit even harder:
  - SSR Mining fell 19%.
  - Newmont dropped 13%—one of the worst S&P 500 performers ([03:16]).
Analysis:
- Gold typically shines during uncertainty, but higher interest rates make yield-bearing assets like bonds more attractive, pulling investment away from the metal.
- Both U.S. and European central banks signaled that rate reductions will be slower than hoped due to inflation risks and economic headwinds from the Middle East energy shock.
Notable Quote:
- “Gold has literally been a hot commodity recently, but now the precious metal is losing its luster.” — Hannah Aaron Lang ([02:57])

4. Micron Technology: Outstanding Earnings, Tepid Response

Q2 Results:
- Revenue nearly tripled year-over-year.
- Adjusted operating earnings beat expectations by 33%.
- Forecasts for next quarter set a gross margin at a striking $0.81/profit per revenue dollar ([04:05]).
Market Reaction:
- Despite the blowout, shares slid 4% post-earnings and 4.8% for the week.
- Skepticism revolves around whether Micron is at its profitability peak—investors want assurance the strong performance is sustainable.
Notable Quote:
- “What they're missing is the assurance that it can last.” — referencing WSJ’s Dan Gallagher’s analysis ([04:35])

5. Super Microcomputer: Legal Trouble, Massive Sell-off

Criminal Charges:
- Three individuals, including Super Micro’s co-founder, were charged by U.S. prosecutors for allegedly smuggling servers with Nvidia chips to China ([05:00]).
- The legal filing described the actions as involving “a tangled web of lies, obfuscation and concealment, all to drive sales and generate revenues in violation of U.S. law.”
Company Response:
- Super Micro placed its co-founder and another employee on leave and fired a contractor.
- While the company isn’t named as a defendant, reputational risk remains high.
Stock Impact:
- Shares plunged about 30% on Friday alone, erasing $4B in market value. For the week, the stock lost 33%, worst in the S&P 500.
Notable Quote:
- “The move in Supermicro stock erased more than $4 billion from its market value...Yikes.” — Hannah Aaron Lang ([05:17])

Memorable Moments

“Yikes.” ([05:17]) — A rare flourish of editorial color, underscoring the shock at the Super Micro collapse.
The host’s repeated emphasis on how quickly market sentiment can shift, and how external shocks (war, rate policy, legal news) can puncture even red-hot narratives around gold and AI stocks.

In Summary

This episode captured a week when global geopolitics, interest rate jitters, and high-profile legal trouble collided to drive big moves in markets. Gold’s prestige as a financial “safe haven” cracked under the pressure of rising rates. Micron’s stellar earnings weren't enough to allay fears about the long-term strength of the AI trade. And Super Micro’s dramatic drop served as a reminder that legal and compliance risks can slam even the most exciting sectors.

hey listeners, it's Saturday, March 21st. I'm Hannah Aaron Lang for the Wall Street Journal and this is what's News and Markets, our look at the biggest stock moves of the week and the news that drove them. Let's get to it. The vibes in financial markets did not get much better this week. There were a lot of big losers, including gold and the companies that mine the precious metal. Chipmaker Micron Technology, in spite of its eye popping earnings, and Supermicro Computer, whose co founder got on the wrong side of U.S. prosecutors this week. But more on that later. First, let's talk about oil, which is really all that anyone is talking about since the war in Iran began three weeks ago. At the beginning of the week, US Stocks shrugged off energy concerns rising, with hopes that perhaps a coalition of countries would work together to open the Strait of Hormuz and the key thoroughfare for a fifth of the world's oil supply. But the mood shifted on Wednesday when the Federal Reserve announced its latest move on interest rates. Policymakers opted to leave rates unchanged, which is pretty much what Wall street expected. But then at a press conference after the decision, Fed Chair Jerome Powell made remarks that investors didn't find very comforting. He highlighted the inflation risks posed by the war in Iran and and so the central bank was in a quote, difficult situation, end quote, that really weighed on stocks. And investors slashed their bets that the central bank would cut interest rates at all in 2026. Combine that with news of attacks on energy infrastructure in the Middle east and it just wasn't a very good week for markets. Brent crude futures, the global benchmark for oil prices, climbed 8.8% this week and US stocks ended down for the week. The Dow and the Nasdaq each fell 2.1%, while the S&P 500 dropped 1.9%. Gold has literally been a hot commodity recently, but now the precious metal is losing its luster. Gold logged its worst week since 2011. One reason has to do with interest rates. Gold is typically a haven that investors flock to during tumultuous periods for the market, but it also thrives when rates are lower. When interest rates are higher, investors tend to ditch the metal in favor of other assets like bonds that can offer a steady income and maybe a more attractive return on investment. US And European central banks this week indicated that rate reductions might not come as quickly as hoped. The energy shock from the war in the Middle east has investors and central bankers worried that inflation could accelerate and economic growth could slow down. Gold has fallen seven of the past eight sessions and ended the week down 9.5%. Other precious metals also sold off this week, taking with them the stocks of mining companies SSR Mining and Newmont. For the week, SSR mining is down 19% and Newmont dropped 13%, putting it as one of the worst performers in the S&P 500 for the week. On the AI front, blockbuster earnings late Wednesday failed to pump up Micron technology investors this week. The memory chip maker's second quarter results were pretty much a blowout. Revenue nearly tripled year over year, while the company's adjusted operating earnings topped Wall Street's estimates by 33%. Micron forecasts stronger revenue growth for the next quarter and expects to earn $0.81 in gross profits for every dollar of revenue, a gross margin that is pretty eye popping for the semiconductor industry. But that might be the problem. Wall street is growing more cautious about the AI trade, and business is so good at Micron that there are concerns that profitability is at or near its peak. As my colleague Dan Gallagher reported, investors are used to seeing big numbers from these kinds of tech companies. What they're missing is the assurance that it can last. Shares of Micron, which have surged more than 300% over the past 12 months, fell almost 4% on Thursday after the company reported results for the week. Shares are down 4.8%. And finally, shares of Super Microcomputer posted one of their biggest daily declines ever on Friday after US Prosecutors charged three people and including the company's co founder with smuggling machines with high end Nvidia chips to China. The stock was down roughly 30% in Friday afternoon trading. Yikes. The move in Supermicro stock erased more than 4 billion from its market value. For context, at Thursday's close, Super Micro had a market cap of roughly 18.5 billion. In an unsealed indictment, prosecutors accused the three people of helping smuggle servers into China through, quote, a tangled web of lies, obfuscation and concealment, all to drive sales and generate revenues in violation of U.S. law. While super Micro wasn't named as a defendant the company did place its co founder on leave after learning of his alleged role in the scheme. The company also said it placed a second employee on leave and fired a contractor. The debacle left Supermicro stock in shambles for the week. Shares lost 33%, the most of any stock in the S&P 500.
