Micron Technology (MU) stock surged 6.10% on Friday, September 4, 2026, closing 58.43 points higher with an additional 1.66% gain in overnight trading. The stock reclaimed the $1,000 price level, driven by DRAM and NAND Flash price increases and strong AI demand. Copper futures also rose amid tariff concerns, potentially boosting memory prices. However, risks include a potential strike by Taiwanese workers and possible Federal Reserve interest rate hikes that could shift investor sentiment away from tech stocks.
Micron Technology (MU) stock prices surged Friday, September 4, 2026, as the asset closed 6.10% higher, gaining 58.43 points. The stock added another 1.66% in overnight trading, reclaiming the $1,000 price level. The rally is likely due to DRAM and NAND Flash price surges, which expanded profit margins. Micron stock price has grown by nearly 13.7x over the last three years, supported by strong demand for memory chips from the AI chip manufacturing industry.
Recent copper futures surges may also be pushing Micron stock higher. Traders are anticipating President Donald Trump’s tariffs to extend to refined copper, leading to large amounts of copper shipping into the U.S. This has caused a global supply shortage of the commodity, and given copper’s importance to the chip industry, memory prices could rise further.
Despite the positive performance, Micron faces risks from Taiwanese workers threatening to strike over the company’s bonus structure. Two unions alone represent nearly 10,000 workers at facilities in Taoyuan and Taichung. This development could increase investor fears and potentially cause a price correction.
Another risk is the possibility of investors de-risking from the memory market. The Federal Reserve may raise interest rates following the lackluster August jobs report. Higher rates could push investors away from tech stocks like Micron and toward safer assets such as gold.
