Micron MU Rises to 871.90 as AI memory demand builds

For Micron investors, that is still fundamentally positive. The company has told regulators that it is advancing process technology to lift bit output per wafer and improve yield, which is exactly what a memory leader needs when customers are pulling for supply. Micron also flagged that China’s restrictions on purchases by critical information infrastructure operators have hurt its ability to compete there, so the real growth thesis now leans more heavily on US, Korean and global AI buildouts than on China recovery.

The stock, however, is no longer trading like a sleepy cyclical. MU has surged to $871.90 from $379.46 in early March, and the move has stretched well above its 50-day and 200-day moving averages. RSI readings remain elevated at 41.4 after a sharp pullback from overbought territory, while the recent flattening in MACD suggests momentum has cooled even as the broader trend remains powerful. In other words, the market already knows memory is in demand; the question is whether it is underestimating how long that demand can persist, or overpaying for it today.

My view is that investors should not confuse a short-term reset with the end of the AI memory trade. The secular case for Micron is intact because every new layer of AI commercialization raises memory intensity, not lowers it. The more the market shifts from model announcements to real deployment, the more indispensable Micron becomes as a supply-chain toll road.

The risk is valuation and timing, not the thesis. If AI capex keeps compounding and memory capacity remains tight, Micron still has room to rerate on earnings power. But after a move of this size, the better entry may come on volatility, not on euphoria. For long-term investors, MU remains one of the most direct picks-and-shovels beneficiaries of the AI infrastructure buildout.
