Micron Technology (MU +0.86%) stock has seen incredible valuation gains thanks to surging demand for memory chips used to power artificial intelligence (AI) technologies. With such massive share price gains, it's not unreasonable to question how much upside the stock still offers. On the other hand, Micron appears cheap across multiple valuation metrics.
Micron is valued at just 13 times this year's expected earnings -- a level that suggests the stock could be significantly undervalued in light of the business's stellar earnings growth in 2026 thus far and the virtual certainty that strong performance will continue through the year. Micron's forward price-to-earnings-growth (PEG) ratio is also far below 1, which can be a good indicator that a stock is undervalued.
Micron trades at low valuation multiples relative to its business performance due to uncertainty about the memory chip market outlook. The memory business has historically been cyclical, and investors are concerned that competition from Chinese rivals could erode pricing power. On the other hand, high demand for memory chips has allowed Micron to book long-term contracts with customers -- so there's a good chance that strong performance will continue for years to come.
