GraniteShares 2x Long MU Daily ETF (MULL) is an exchange-traded fund (ETF) launched in November 2024 that aims to deliver investment results equal to two times (200%) the daily percentage change of Micron Technology's common stock. It achieves this exposure primarily through swap agreements rather than by holding Micron shares directly, and it carries a net expense ratio of about 1.50%.
This distinction matters enormously for investors considering a $40 ETF price target. MULL is not a diversified basket of semiconductor names; it is a magnified, single-day bet on one volatile memory-chip maker. That concentration amplifies both gains and losses relative to MU itself.
The $40 mark is a natural focus point for two reasons. First, it is a clean psychological milestone that sits just beneath the fund's 52-week high of $43.53, reached in late June 2026. Second, it represents a meaningful but not implausible recovery from the roughly $22 range MULL traded at in August 2026, following a sharp pullback from those highs.
For context, MULL's 52-week range spans from well under $1 to over $43 — an extraordinary degree of volatility that reflects both Micron's powerful rally and the leverage embedded in the fund. A move back toward $40 would essentially require MULL to retrace most of the distance toward its all-time high.
The single most important driver of a MULL price forecast is the underlying demand for Micron's products. Micron is one of the world's largest producers of DRAM and NAND memory, and it has become a critical supplier of high-bandwidth memory (HBM) used in artificial-intelligence data centers. Strong AI-driven demand for memory has been a central theme supporting MU's share price, and by extension MULL.
If memory prices remain firm and Micron sustains upward momentum, the 2x daily leverage in MULL can produce rapid gains. A sustained Micron advance of roughly 40% or more would, in broad terms, support a doubling in MULL toward the $40 area — although the exact math is complicated by the daily reset and by the fund's own expenses.
The most serious obstacle to reaching $40 is structural rather than fundamental. Leveraged ETFs such as MULL reset their exposure daily, which means they do not reliably deliver 2x returns over holding periods longer than a single trading session. In choppy markets, the process of daily rebalancing can erode value even when the underlying stock is roughly flat or only modestly higher over time — a phenomenon known as volatility drag.
MULL's recent price history illustrates the risk. After peaking above $43 in late June 2026, the fund fell into the low teens by late July before recovering toward the low $20s in August. Micron itself is highly cyclical, and any downturn in memory pricing, softening AI capital spending, or broader semiconductor weakness could quickly reverse the fund's gains.
From a technical analysis perspective, $43.53 stands as the dominant resistance level and the ceiling the fund would need to clear to establish new highs. Below it, the $40 round-number zone acts as a meaningful supply area. On the downside, the $17–$18 range provided a notable bounce in recent sessions, while the low-to-mid teens mark the more critical support zone tested in July.
Because MULL tracks Micron with leverage, technicians watching this fund effectively track the supply-and-demand zones in MU itself, scaled upward. A decisive break of Micron's own prior highs would be a constructive signal for the leveraged vehicle.
For MULL to realistically approach $40, several conditions would likely need to align: sustained strength in memory pricing, continued robust AI-related demand for Micron's HBM and DRAM products, and a broad risk-on environment that supports the semiconductor sector. Equally important, the move would need to occur in a relatively orderly fashion, since violent two-way swings are precisely what erode value in daily-reset leveraged products.
Investors should note that analyst price targets are typically published for Micron itself rather than for the leveraged ETF. Those targets serve as a rough proxy for where MU might trade, but they do not translate mechanically into a MULL target because of leverage and compounding effects.
Traders evaluating volatile instruments like leveraged ETFs may benefit from tools designed to monitor shifting conditions efficiently. Tickeron's AI Daily Buy/Sell Signals use artificial intelligence to continuously scan thousands of stocks and ETFs, generating Buy, Sell, or Hold signals based on technical behavior, changing market conditions, and AI-driven analysis. These signals can help traders surface new opportunities, keep track of existing positions, and identify emerging trend shifts more quickly than manual screening alone. For those following fast-moving funds such as MULL, automated signal monitoring can provide an additional layer of market awareness.
The $40 target for MULL is ambitious but not beyond the realm of possibility, given that the fund traded above that level as recently as mid-2026. The strongest support for the move comes from the powerful AI-driven memory cycle propelling Micron, amplified by the fund's 2x leverage. The primary risks are equally clear: daily-reset leverage, extreme volatility, and Micron's own cyclical sensitivity all make a sustained rally far from guaranteed. Investors should watch Micron's memory pricing dynamics, its earnings trajectory, and the fund's ability to hold key technical levels rather than relying on any single price forecast.
