Micron Technology Inc (NASDAQ:MU) is back above the $1,000 mark, extending a 2026 rally that has made the memory-chip stock one of the market’s hottest AI trades, keeping its leveraged ETF counterparts firmly in the spotlight.
Micron shares have gained about 260% year to date and climbed roughly 36% from their July low. The latest move is giving fresh momentum to two ETFs offering direct 2X exposure: Direxion Daily MU Bull 2X Shares (NASDAQ:MUU) and GraniteShares 2x Long MU Daily ETF (NASDAQ:MULL).
• GraniteShares 2x Long MU Daily ETF stock is surging to new heights today. What’s driving MULL stock higher?
MUU, MULL Amplify Micron’s Moves
Both funds target 200% of Micron’s daily return, making them among the most aggressive ETF vehicles for traders bullish on Micron.
MUU has delivered an extraordinary return in 2026. Market data shows the ETF has gained around 588% since the start of the year, although its July 15 20-for-1 split means historical share prices need to be adjusted when comparing performance.
MULL, meanwhile, is also designed to deliver 2X Micron’s daily percentage change and uses swaps to obtain that exposure. GraniteShares lists the fund as an active-trading vehicle and warns that daily resetting means its longer-term return can differ substantially from twice Micron’s cumulative performance.
The volatility cuts both ways.
For instance, in early June, MUU plunged almost 40% in a single session after Micron fell roughly 21%, before surging more than 80% again over the next couple of weeks, illustrating how quickly leverage can magnify a reversal.
AI Memory Demand Keeps the Trade Hot
The fundamental backdrop remains supportive.
Micron’s HBM3E and HBM4 products are benefiting from surging demand for AI infrastructure, as hyperscalers expand data center capacity and Nvidia and AMD accelerators require increasingly sophisticated memory.
Early this month, JPMorgan strategist Jay Kwon warned in a note that the memory supply crunch could persist for another two years, with demand broadening from GPUs to CPUs, according to Yahoo Finance. Tight supply combined with stronger pricing could keep Micron’s revenue and earnings cycle elevated for longer than investors expect.
Trivariate Research’s Adam Parker has made an even more bullish case, arguing that consensus estimates may assume Micron’s earnings peak will fade too quickly. He suggested the company could generate close to $300 billion in free cash flow over two years and said he would not be surprised if Micron eventually reached a $1 trillion market capitalization.
Broader ETFs Also Benefit
Micron’s strength is also filtering into diversified semiconductor and momentum ETFs.
iShares Semiconductor ETF (NASDAQ:SOXX) and VanEck Semiconductor ETF (NASDAQ:SMH) offer broader semiconductor exposure, while Strive US Semiconductor ETF (NYSE:SHOC), Global X AI Semiconductor & Quantum ETF (NASDAQ:CHPX) and First Trust Nasdaq Semiconductor ETF (NASDAQ:FTXL) have meaningful Micron positions of more than 12%. Invesco S&P 500 Momentum ETF (NYSE:SPMO) provides a broader momentum strategy with significant Micron exposure, while memory-focused Tuttle Capital Concentrated Memory Stack ETF (BATS:HBMX) offers another way to play the sector’s structural supply constraints.
For traders betting that Micron’s earnings cycle and AI-driven memory boom have further to run, however, the 2X products remain the highest-octane ETF expression of the thesis.
