Micron Technology climbed back above $1,000 on Monday, rising about 5% to 6%, as a broader rally in memory and semiconductor shares gained support from expectations that AI infrastructure demand will keep DRAM and NAND supply tight for longer. Investors cited Micron management's view that demand continues to exceed supply beyond 2027, comments from Elon Musk and Peter Diamandis describing memory as an AI bottleneck, bullish analyst calls including UBS's $1,625 Micron price target, and remarks from U.S. Commerce Secretary Howard Lutnick that the Trump administration does not support Apple buying memory chips from China. The move also renewed attention on leveraged Micron funds such as Direxion Daily MU Bull 2X Shares and GraniteShares 2x Long MU Daily ETF, which seek 200% of Micron's daily move but can diverge sharply from the stock over longer periods because of daily resetting.
