CaiLian Press reported on November 6 (edited by Bian Chun) that due to positive industry signals of HBM4 price increase, the stock price of US memory chip giant Micron Technology rose sharply on Wednesday, hitting a new high.

As of Wednesday's closing, the stock price of Micron Technology surged nearly 9% to $237.5, with an intraday high of $239.88.

Micron Technology is one of the hottest semiconductor companies in 2025. Driven by the demand for high-bandwidth memory (HBM) driven by spending on artificial intelligence infrastructure, the company's stock price has surged more than 180% this year.

Micron Technology's stock price received new momentum on Wednesday as its Korean competitors sent positive market signals.

SK Hynix announced on that day that it had completed the price and quantity negotiations with Nvidia regarding the supply of HBM4 next year. A source familiar with SK Hynix said, "The supply price of HBM4 will be more than 50% higher than that of HBM

SK Hynix's HBM4 supply to Nvidia has been confirmed with a unit price of approximately $560 (about 800,000 Korean won). The industry had previously expected the unit price of SK Hynix's HBM4 to be around $500, but the actual delivery price exceeded e

This news further boosted the bullish sentiment across the entire storage industry, leading to a surge in the U.S. storage sector. Both Seagate Technology and SanDisk rose more than 10% on Wednesday, while Western Digital rose more than 5%.

The explosive rise in the stock price of Micron is attributed to the perfect storm of supply restrictions and a surge in demand driven by artificial intelligence.

Micron's financial report shows that its HBM (high bandwidth memory), high-capacity DIMM (dual in-line memory module), and server LP DRAM (low-power dynamic random-access memory) products are expected to generate a combined revenue of $10 billion in

Citibank analyst Christopher Danely recently raised his target price for Micron Technology to $275. He predicts that DRAM prices in the fourth quarter will rise by 25% compared to the third quarter, which will create the highest quarterly increase si

BNP Paribas Exane upgraded Micron Technology's rating from 'underperforming' to 'performing better than the market' mid-month, with its target price rising from $100 to $270.

Weiss Ratings, an independent financial rating agency in the United States, upgraded its rating for Micron from 'hold' to 'buy' earlier this month, joining the ranks of major investment banks that are bullish on the company.

However, there is still some cautious sentiment in the market. Reports indicate that Micron's HBM4 design faces challenges in terms of yield and performance, and may require nine months of re-design, which could delay mass production.

Meanwhile, SK Hynix and Samsung are actively expanding production capacity. Whether or not Micron can narrow the gap with them in the field of HBM4 will be key to maintaining its market share growth.
