Wall Street is becoming increasingly bullish on Micron (NASDAQ:MU). Citi recently raised its estimates, citing stronger-than-expected DRAM pricing. Analysts also believe that tight memory supply and AI-driven demand could support earnings well into 2027. However, strong demand does not automatically make the stock attractive.
With Micron already having rallied sharply, investors need to consider whether the expected improvement in earnings is already priced into the stock. This raises a question of whether there is still enough upside after the rally.
The company’s Q4 earnings beat expectations, with Q4 revenue coming in at $54.2 billion, up 379% YoY. Despite the impressive result, there was no excitement in post-market trading as the stock traded flat after the announcement.

The Memory Cycle Could Turn
Despite strong quarterly results, the main risk to the bullish case is that Micron’s current earnings strength may depend on tight memory supply. Goldman Sachs’ concern adds to this bear thesis. The firm expects another strong quarter but remains cautious about longer-term competitive supply additions, particularly from China. For now, Micron remains one of the major global memory suppliers, but it may face competition in the future. Chinese chipmaker CXMT is reportedly preparing to enter the NAND market, expanding beyond its core DRAM business. While this is not an immediate threat to the current supply shortage, it highlights the potential risk from competitors over time. If new capacity eventually catches up with demand, DRAM and NAND prices could weaken, putting pressure on MU’s earnings.
Micron’s valuation sends mixed signals. The forward GAAP P/E of 15.03x looks cheap, especially for a company of this scale growing this fast. The reason the P/E multiple stays low is the cyclical nature of the memory business. Investors worry that the boom won’t last and that things could change drastically in a few years. The forward Price-to-sales ratio tells a different story. At 9.53x, it sits about 130.18% above its 5-year average of 4.14x, which shows how far the stock has run.
Micron’s earnings outlook remains strong, but its valuation and future supply risks create uncertainty. While analysts expect further growth, investors may want to see sustained pricing strength in the coming quarters before deciding whether MU’s rally can continue.
Institutional interest in Micron rose sharply, with hedge fund ownership increasing to 184 funds at the end of Q2 2026 from 154 at the end of Q1 2026. However, short interest remains at 2.64% of float as of August 31, 2026.
