The Motley Fool's analysis points out that the biggest question for Micron Technology (MU) stock is how long the current supply shortage in memory and storage products will last. While Micron's stock is up around 600% over the past 12 months and trades at about 20 times trailing earnings (compared to the S&P 500's 26 times), the long-term outlook is influenced by potential supply increases. South Korean memory company SK Hynix recently announced plans to invest over $38 billion in new facilities, which could ease the shortage in a year or two, potentially impacting Micron's significant growth from high prices.
