Simplify US Equity PLUS Convexity ETF (SPYC)

The Simplify US Equity PLUS Convexity ETF (NYSE Arca: SPYC) is an exchange-traded fund that holds a core position in the S&P 500 while layering in long call options to create an asymmetric return profile — seeking to capture upside gains in a rising market while limiting downside losses when equities sell off.

The convexity idea

Most S&P 500 tracking funds pursue price replication: they own the index’s constituent stocks in proportion to their market value and aim to match its returns, minus fees. The Simplify PLUS Convexity fund takes a different approach. It buys and holds S&P 500 index futures or stocks, but it uses a portion of the assets to purchase out-of-the-money call options on the index. Those options create an economically convex payoff — losses are muted on the downside, gains are amplified on the upside, and the inflection point (the strike price of the calls) is chosen to create that asymmetry across a realistic range of market moves.

The appeal is intuitive: in a flat or rising market, the call options become increasingly valuable; in a sharp down move, the losses from the underlying S&P 500 position are partially offset by the optionality built in. This is not a hedge against catastrophe — the fund does not insure against tail events with deep out-of-the-money puts — but rather a reshaping of the risk-reward curve to favor positive surprises and tolerate moderate declines.

How it works operationally

Simplify funds are known for transparent, rule-based strategies that disclose their holdings and rebalancing schedules. The PLUS Convexity fund maintains a long position in S&P 500 index exposure (typically through futures for efficiency) and systematically rolls long call positions, using option premiums and a small portion of the fund’s assets to pay for the convexity. The options are generally near-the-money or slightly out of the money, so they are far cheaper than deep out-of-the-money insurance but still provide meaningful leverage on a strong rally.

Because options decay in time value, the fund must continuously refresh its call positions — purchasing new calls as old ones expire, capturing some decay cost along the way. This is a deliberate trade-off: the fund pays a small, measurable friction to buy convexity. A sustained rally works in the fund’s favor; a long sideways market works against it, as decay erodes option value without the index moving higher to compensate.

Costs and structure

The fund is a traditional ETF (not leveraged, not inverse), listed on a US exchange and tradable like any equity security. It has an expense ratio that reflects both the core index exposure and the cost of the options strategy. That ratio is higher than a plain S&P 500 ETF, because the convexity has a real price — in fees, in bid-ask spreads, and in the time-decay drag inherent to holding options over months. Investors pay for the asymmetry they want, and that cost is material enough to matter in a sideways-to-down market.

Liquidity is typically good during regular trading hours, as the fund is designed to be traded by retail and institutional investors. The underlying S&P 500 exposure is highly liquid, and while the options strategy adds some friction at the margins, the fund’s structure allows the issuer to create and redeem shares efficiently.

When this strategy gains and loses

The convexity approach shines when markets rise sharply or when they stay relatively flat (because the fund captures upside but does not suffer as much from time decay in a stable environment). It loses in three scenarios: first, a fast downward move where the losses exceed the value provided by the call options; second, a prolonged sideways market where option time decay costs more than any upside capture; and third, a slow, grinding decline over months that exhausts the options’ value before the market recovers. The strategy is not “free” — it buys upside sensitivity at the cost of giving up some of the gains the raw S&P 500 would deliver in a stable, moderate rally.

What makes it different from other S&P 500 ETFs

Plain index trackers like SPY or VOO aim for low costs and price-matching precision. Sector-tilted funds or factor-focused ETFs (value, growth, momentum) change the composition of the index itself. The convexity approach leaves the composition alone but reshapes the payoff — it is still an S&P 500 fund, but with an intentional non-linearity built in. For investors who believe volatility is mispriced or that the next several years will see outsized moves, the fund offers a structured way to act on that view without managing options directly.

It is also simpler than a do-it-yourself options overlay, because the fund handles the rolling, monitoring, and rebalancing. An investor who buys shares owns a transparent, auditable strategy rather than managing the mechanics themselves.

Risks and suitability

The main risk is that the convexity costs more than it is worth — either because the market moves sideways (eroding option value), falls in a way that overwhelms the call spread, or rises so gradually that the gains are offset by the fees. Investors buying this fund are making a bet on volatility or on larger-than-typical market moves; if the next five years see an index return inline with historical averages in a smooth uptrend, the convexity will have been an expensive anchor.

The fund is best suited to investors with a medium-term horizon (2–5 years) who expect elevated equity volatility, who want S&P 500 exposure but believe the next bull market will have pronounced rallies and drawdowns, or who are willing to pay for the peace of mind that the strategy’s downside cushion provides. It is not a buy-and-hold-forever core holding, nor is it a risk-off insurance strategy. It is a tactical bet on volatility and upside capture, sized accordingly.

How to evaluate it

The fund’s prospectus and factsheet lay out the call-option strategy in detail, including the strike prices, expiration schedule, and the current ratio of option notional to equity notional. An investor should compare the fund’s expense ratio to a plain S&P 500 ETF and ask whether the difference is justified by the expected convexity benefit over the intended holding period. Historical returns alone are not enough, because the strategy’s value depends on realized volatility going forward.

The fund also publishes daily holdings and positions, which allows investors to see exactly what the convexity overlay looks like at any time. The best research step is to review a few quarterly or annual updates, understand the rolling mechanics, and paper-trade the strategy in a range of scenarios — up markets, down markets, sideways markets — to build intuition for when the convexity will help and when it will hurt.
