Our read on BIOY
FMost sector income funds sell calls on the sector itself. BIOY goes one level up: it sells puts on a 3x leveraged biotech ETF, mining the fat premiums that come with one of the market's twitchiest wrappers, and pays cash out weekly.
The Fund seeks to generate three times the income from selling options on the S&P Biotechnology Select Industry Index through options on leveraged ETFs, while also seeking exposure to the leveraged ETF’s performance subject to a cap.
Why people hold it
- The income engine is the whole point: writing puts on a 3x biotech ETF harvests the elevated implied volatility leveraged funds throw off, with distributions paid weekly.graniteshares.com
- It doesn't hold the leveraged biotech ETF. Exposure runs through the options book, aiming at 3x the income from selling options on the S&P Biotechnology Select Industry Index.graniteshares.com
- One ticker replaces a standing options program: strike selection, short-dated expiries and the weekly roll are handled inside a 1940 Act fund.graniteshares.com
- GraniteShares discloses that payouts can include return of capital, so the character of each distribution is documented rather than left to guesswork.graniteshares.com
Worth knowing
- At 1.07%, the fee runs about triple the 0.35% median of its sector-overlay peer group, where the State Street Premium Income funds (XLVI, XLUI) sit.
- The payoff shape is lopsided: upside is capped by design while the put book absorbs the downside of a 3x daily biotech ETF, a tool built for one-day moves.
- Small and thinly traded, and it only started trading in 2026, so there is little history behind it and execution costs deserve attention.
