Micron Technology (MU) has been a prominent name in artificial intelligence trading for most of 2026, with its shares gaining an explosive 173.92% since the beginning of the year.
At the end of May it exceeded $1 trillion in market value.
And then things changed.
For two business days, a big part of that race disappeared.
The stock lost 8% Thursday June 4 and another 13% on Friday, June 5. Altogether, about a fifth of its value disappeared in two sessions.
The decline didn’t start with Micron, however.
This is what happened:
How Micron’s Two-Day Collapse Unfolded
Micron (MU) closed Friday down about 13%, its steepest single-day drop in years, after already losing 8% the day before.
The sale was extensive. The iShares Semiconductor ETF (SOXX) fell 10% on Friday, its worst day since March 2020, according to Congress.net.
Marvell Technology fell more than 16% and chip stocks lost $1 trillion in combined market value.
Micron It was not the trigger, but it fell harder than almost any of its peers. This may have been because the Stocks that rise faster tend to return more when sentiment changes.
“Investors have been kind of hovering over this sell button,” said Mark Hackett, chief market strategist at Nationwide.

Why a Memory Stock Got Caught in a Custom Silicon Clearance
The spark came from Broadcom (AVGO), not Micron.
Broadcom’s results were in line with expectations, but its AI revenue guidance fell short of high hopes. Its shares fell about 12% on Thursday and continued to fall.
Broadcom’s business runs on custom application-specific integrated circuits, or ASICs, chips built for a single customer’s AI workloads.
And although this is a different product from Micron memory chips, When an AI leader stumbles, traders sell the entire group first and resolve differences later.

That same morning a second pressure came. The May jobs report showed 172,000 new jobs, well above the 80,000 economists expected, CNBC reported.
Increased hiring pushed the 10-year Treasury yield above 4.5% and raised the odds of a Fed rate hike this year to 70%, according to the CME FedWatch tool.
When interest rates rise, Fast-growing companies are often hit hard.and Micron was a perfect reflection of that.
How far had Micron run before the fall?
Micron’s fall looks worse because of how far it had risen first.
The stock had more than doubled by 2026, returning around 137% so far this year. early may before rising to surpass $1 trillion in market value on May 26.
The rebound was based on real demand.
Micron makes high-bandwidth memories, or HBMs, stacked chips that sit next to AI processors and feed them data fast enough to train large models.
More AI actions:
All of its 2026 HBM production is already sold out, according to 24/7 Wall St., and management says it can only meet between half and two-thirds of customer demand.
That shortage also raised prices for standard memory, both dynamic random access memory (DRAM), used for live computing, and NAND flash memory, used for storage.
But the same race left a warning sign.
Micron’s Relative Strength Index, a momentum indicator, hit 85 in mid-May, deep in overbought territoryand such high readings are rarely sustained for long.
What the liquidation means now for Micron investors
The two-day drop reset the price, not the business. HBM is still sold out and Wall Street remains divided over how high its shares can rise.
Here’s how Micron’s decline compares to the broader market:
Micron versus the market, June 4-5
Micron: fell about 20% in two sessions
iShares Semiconductor ETF: down 10% on Friday
Nasdaq Composite: drops 4.18% on Friday
S&P 500: drops 2.64% on Friday
The gap shows how much a top-flyer falls compared to the broad index when momentum reverses.
Analysts’ objectives still vary widely.
Mizuho reaffirmed an outperform rating with a target of $800 in late May, according to Investing.com, while Goldman Sachs maintained $400, The Globe and Mail reported, a reminder that Even the bulls disagree with the math..

The risk is easy to detect.
Memory has always been cyclical, with strong booms followed by excesses in which supply drastically exceeds demand. And a stock valued for perfection is greatly affected by any setback.
However, none of that erases the history of the lawsuit. It means the next stage of profits depends on Micron exceeding high expectations instead of just knowing them.
