SIOO vs SPCI

SIOOAVistaShares Target 15 S&P 100 Distribution ETF

SPCIFTuttle Capital Space Industry Income Blast ETF

In short

SIOO Most equity-income ETFs pay out whatever the options market hands them. SIOO starts from the answer: a 15% annual income target, paid monthly, bolted onto an S&P 100 core using index options that carry 60/40 tax treatment.

SPCI Space-theme income funds usually sell calls and cap the upside. SPCI flips it: roughly 100% exposure to the Syntax Space Industry Index, with premium harvested from put credit spreads instead. The income comes off the downside, not the upside.

Stated mandate

SIOO The actively managed ETF seeks income and, secondarily, long-term capital appreciation. It combines equity exposure based on the S&P 100 Index (OEX) with an options portfolio intended to generate income.

SPCI The Fund seeks current income.

Why people hold it

• SIOO 0.59% expense ratio, below the 0.75% typical for options-income funds. Modest toll for an actively managed overlay.
• The overlay uses S&P 100 (OEX) index options, section 1256 contracts taxed at blended 60/40 rates, and the manager also hunts tax-loss harvesting in the equity sleeve.vistashares.com
• You keep the stocks. The equity sleeve generally mirrors the S&P 100's mega-cap roster, with the income machinery layered on top rather than replacing it.vistashares.com
• The payout target is stated up front: 15% a year, distributed monthly. A published yardstick you can hold the fund to, rather than a mystery yield.vistashares.com

• SPCI Aims to keep about 100% economic exposure to its space index using stock and deep in-the-money calls, so the income engine is not built by selling away the theme's upside.newsfilecorp.com
• Premium comes from put credit spreads: sell a near-the-money put, buy a lower-strike put. Defined-risk structure with a floor under the short leg, not a naked short put.newsfilecorp.com
• The index reaches across the whole space stack (satellite operators and manufacturers, launch, GPS and geospatial, spacecraft) and holds pure-play and partial-exposure names, rebalanced quarterly.newsfilecorp.com
• Built to send cash out on a recurring schedule rather than reinvest it, with option premium funding the payout.

Worth knowing

• SIOO 15% is a target, not a coupon. Distributions can include return of capital, which sends part of your own principal back and trims net asset value.vistashares.com
• Income comes from an actively managed options book, so the outcome rides on manager decisions and options pricing instead of a fixed dividend stream.
• Launched in December 2025 and still a small, lightly traded fund. Short history and wider bid-ask spreads come with that territory.

• SPCI The 0.99% fee sits above the option-income peer median of 0.74%, and above established names in the group such as DJIA (0.60%) and AIPI (0.65%).
• A small, thinly traded fund. Wider bid-ask spreads are the usual trade-off, and size like this leaves less cushion if interest stays light.
• Full index exposure plus short puts means both legs lean the same way in a selloff, and the strategy launched in 2026, so there is little history to judge it on.newsfilecorp.com
