What Happened?

Shares of memory chips maker Micron (NASDAQ: MU) jumped 7.9% in the afternoon session after the VanEck Semiconductor ETF jumped nearly 5% in response to the de-escalation of the U.S.-Iran conflict. 

The sector rallied specifically because semiconductors were highly vulnerable to the supply chain disruptions that occurred during the war. The reopening of the Strait of Hormuz is a critical victory for the industry, as the waterway is essential for the transit of noble gases and materials used in chip fabrication.

What Is The Market Telling Us

Micron’s shares are extremely volatile and have had 44 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 2 days ago when the stock gained 3.1% on the news that investors reacted to a bullish note from KeyBanc Capital highlighting continued strength in memory pricing and sustained demand tied to AI infrastructure. 

The note reinforced expectations that earnings momentum could extend into the coming quarters. This optimism followed a recent fiscal second-quarter report where Micron posted an impressive growth. That explosive growth was driven by strong global demand for High Bandwidth Memory (HBM), which is essential for feeding powerful AI systems. The positive market sentiment was also tied to the idea that demand for memory solutions for these workloads may bolster long-term prosperity for the firm.

Micron is up 28.7% since the beginning of the year, but at $406.06 per share, it is still trading 12.1% below its 52-week high of $461.73 from March 2026. Investors who bought $1,000 worth of Micron’s shares 5 years ago would now be looking at an investment worth $4,261.
