Our read on MUYY
BMost single-stock income funds sell calls on the stock. MUYY works the other side of the book: it sells puts tied to a 2x leveraged Micron ETF, letting the leverage do the premium-gathering, and pays out monthly.
The fund seeks income through options strategies, primarily by selling put options on leveraged ETFs tracking the 2x Long MU Daily ETF.
Why people hold it
- The twist is the reference asset. Premium comes from selling puts linked to a 2x leveraged Micron fund rather than MU shares, and bigger daily swings price options higher.graniteshares.com
- Distributions are monthly, and the wrapper is a standard 1940 Act ETF: no futures account, no separate paperwork, it trades like anything else in the brokerage window.graniteshares.com
- The 1.07% fee sits at the median for single-stock options-income funds. Some peers undercut it (KWIN at 0.51%, TSMY at 1.01%), and plenty charge more.
- In a crowded field of single-stock income funds, this is one of the steadier builds, with modest trading friction for something this specialized.
Worth knowing
- Put sellers keep the premium, not the rally. Upside is structurally limited to what the options bring in, however far Micron runs.
- The risk travels through a leveraged fund. The reference vehicle aims for twice Micron's daily move, so rough stretches land harder on the short-put side.
- Launched in 2026, so the history is short and covers one market stretch rather than a full cycle of memory-chip booms and busts.
