IMST vs MSTY: Which Is the Better Pick in 2026?

Overview

IMST and MSTY are both single-stock options income ETFs that generate yield by selling covered calls on MicroStrategy (MSTR) stock while maintaining upside participation. The key distinction: MSTY distributes weekly at a 59.35% rate, while IMST pays monthly at 10.92%. MSTY launched earlier and holds $1.01B in assets; IMST is newer, with $11.7M AUM.

How they differ

The most obvious difference is distribution intensity. MSTY's 59.35% annualized yield dwarfs IMST's 10.92%—a spread that reflects MSTY's strategy of selling shorter-dated, deeper out-of-the-money calls to capture premium more aggressively, distributing gains weekly rather than monthly. That structural choice also explains the asset-base gap: MSTY's extreme income yield attracted $1.01B in capital, while IMST's more conservative approach launched just three months prior with $11.7M. Both charge nearly identical expense ratios (0.99% and 0.96%), so fees are not the differentiator. MSTY carries a higher beta of 2.56 versus IMST's 2.31, suggesting greater leverage or more aggressive call strikes that amplify MSTR's already-volatile moves.

Who each is best for

IMST: Fits investors seeking monthly income from a covered call strategy who prefer a lower payout ratio and want to limit the risk of rapid NAV erosion on a single volatile stock. The 10.92% yield balances income generation with structural modesty.

MSTY: Designed for investors chasing maximum current income from MSTR's volatility and willing to accept steep NAV decay in exchange for very high near-term distributions. Weekly payouts suit those building a ladder of frequent income streams or rebalancing constantly.

Key risks to know

• NAV erosion at extreme yields. MSTY's 59.35% distribution rate far exceeds realistic long-term total returns on MSTR stock, meaning distributions will rely heavily on return of capital and principal erosion. Even IMST's 10.92% yield sits above typical equity appreciation and will chip away at NAV over time if MSTR underperforms.

• Single-stock concentration and volatility. Both funds hold only MSTR through an options overlay, inheriting the stock's elevated beta (around 2.3–2.6) and crypto-correlated price swings. A sharp MSTR decline can drain both the underlying value and the call premium available to generate future income.

• Call assignment and capped upside. Covered call strategies cap gains if MSTR rallies sharply; your participation ends at the strike. On a stock with MSTR's volatility, missing a major run-up can compound opportunity cost over time.

• Options liquidity and strike selection risk. Both funds depend on liquid MSTR options markets to execute their call sales. If MSTR's options volume dries up or implied volatility collapses, premium generation slows and distributions may decline.

• Recency and asset-base risk for IMST. IMST's very recent inception (November 2024) and tiny $11.7M AUM mean the fund has not weathered a full market cycle, and small funds risk closure if assets don't grow.

Bottom line

If you want predictable monthly income with a yield that appears sustainable relative to underlying returns, IMST's 10.92% payout is more conservative. If you prioritize extracting maximum immediate cash from MSTR's volatility and accept that your principal will shrink, MSTY's 59.35% weekly distribution delivers higher near-term income—but at the cost of rapid NAV decay. Both are single-stock bets that require conviction on MSTR; past performance doesn't predict future results.
