Key Takeaways
- Micron stock rose more than 5% Friday after board member and former TSMC co-CEO Mark Liu disclosed a $7.8 million share purchase.
- The buy comes amid strong AI-driven demand for memory chips, which has propelled Micron’s stock price in recent months.
Micron (MU) just got a powerful vote of confidence.
Shares of the chip maker jumped Friday after Mark Liu, a current member of Micron’s board of directors and a former co-CEO of Taiwan Semiconductor Manufacturing Co. (TSM), purchased 23,200 Micron shares earlier this week, according to a regulatory disclosure filed late Thursday. The shares were worth about $7.8 million as of Thursday’s close.
Why This Matters
Micron stock is among the top gainers in the S&P 500 and Nasdaq 100 over the past 12 year amid surging AI driven demand for the company’s memory chips. The $8 million purchase from a veteran semiconductor executive such as Mark Liu provides an additional bullish signal.
Micron stock was up more than 5% in afternoon trading Friday, making it the top performer in the Nasdaq 100 index.
Liu’s purchase comes after a major run-up in Micron stock, making it all the more bullish of a signal for tech investors. Micron shares have surged nearly 250% over the last 12 months amid booming demand for memory and data storage devices from the AI data center buildout.
That optimism is bolstered by Micron’s expansion plans: The company in June announced plans to expand its domestic production to the tune of about $150 billion in memory manufacturing and another $50 billion in research and development (R&D).
Micron shares have gained about 25% already in 2026. Sandisk (SNDK), Western Digital (WDC), and Seagate Technology (STX) are among the other stocks benefiting from the memory shortage. Shares of Sandisk are up more than 1,000% since being spun off from Western Digital last February. Western Digital and Seagate stocks have risen about 350% and 240%, respectively, in the past 12 months.
