Micron Just Had Its Worst Week of 2026. Is Earnings Season the Turning Point?

Micron Technology (NASDAQ: MU) stock just experienced one of the worst weeks of 2026, with shares falling around 19.5% in the past five trading days (as of March 26). The stock is now down over 23.5% from its recent high of $471.34 earlier this month, as investors worry about the durability of memory demand amid profit-taking and increasing macro uncertainty.

The sell-off has been surprising, especially after the company delivered solid performance in the second quarter of fiscal 2026 (ended Feb. 26).

Disconnect between fundamentals and stock performance

Micron has plans to increase capital expenditures (capex) to over $25 billion in fiscal 2026, with a significant portion allocated toward future memory capacity expansion. The company also expects construction-related capex to rise by more than $10 billion year over year in fiscal 2027 as it builds out its global manufacturing footprint. Against this backdrop, investors are concerned that memory prices, currently supported by tight supply and strong artificial intelligence (AI)-driven demand, could begin to normalize, negatively affecting Micron's future profitability.

Additionally, a recent announcement from Alphabet around memory-efficient AI processing has triggered fears that AI workloads may require less memory, further contributing to the recent sell-off.

However, this bearish narrative may be ignoring the actual extent of supply constraints in the memory market. In the recent earnings call, Micron's management highlighted that some of its customers were receiving only one-half to two-thirds of their medium-term memory needs. The company also expects tight supply-demand conditions to persist beyond 2026. Supply can remain constrained for a much longer time due to limited cleanroom capacity, long construction lead times before new fabs become operational, and lower efficiency gains in memory output per wafer with new manufacturing technologies. The company is also entering into multiyear strategic customer agreements, including its first five-year deal, which provides better demand visibility and supply commitments across memory cycles.

Hence, if Micron's upcoming earnings continue to validate supply constraints and rising AI-driven memory demand, the recent pullback could prove a turning point or a smart entry point for long-term investors.
