TrueShares Structured Outcome (March) ETF (MARZ)

MARZ, the TrueShares Structured Outcome (March) ETF, is an exchange-traded fund that approaches equity exposure through options rather than direct stock ownership. It operates on a defined-outcome framework: it buys call options and sells put options on the S&P 500, effectively capping how much you can gain in a strong market while providing an 8-12% cushion—aiming for 10%—against initial losses. The fund resets its entire position each March.

How the strategy works

MARZ does not own the S&P 500 itself. Instead, it uses options to construct a synthetic return profile. On each investment day (typically the first business day of March), the fund simultaneously purchases call options and sells put options on the S&P 500 Index, with all positions set to expire on the next roll date. This simultaneous long-call and short-put structure creates the fund’s core payoff: losses below the buffer threshold are absorbed by the sale of put options, while gains above a preset cap belong to the fund’s investors who own the shares.

The effect is a carefully defined outcome for that quarter: the fund will not fall more than 8-12% if the market drops sharply, but it also won’t capture gains beyond a predetermined level if the market rallies hard. For investors, the trade is explicit—you’re swapping unlimited upside for a measure of downside comfort.

The index and the fund’s purpose

MARZ tracks the S&P 500 Index, the 500 largest publicly traded U.S. companies. The fund is not seeking to match that index’s return; it is seeking to deliver a shaped version of it. The S&P 500 returned roughly 10% annually over recent decades, but with volatility—sharp drawdowns are part of the journey. MARZ aims at a smoother path by accepting capped gains in exchange for those buffer protections.

The fund is not a hedge or an insurance product. It is a direct investment—you own shares of MARZ itself, and those shares trade on NYSE Arca like any other ETF. The options positions underneath are the fund’s internal machinery, not a separate purchase you make on top.

Mechanics and timeline

The fund’s defining feature is the quarterly reset. Each March, all old options expire and new ones are written. The dates and strikes are determined by MARZ’s advisor at the start of each period. This means the buffer level and the upside cap are set three months in advance and do not change until the next roll. If the market is calm, the buffer and cap stay as designed. If the market moves sharply within that three-month window, the payoff you receive at the end is still locked by the original structure.

The fund holds Treasury bills and money market instruments between option positions to ensure sufficient collateral for the strategy. This generates some yield, though it is modest.

Costs and who trades it

MARZ charges an annual management fee of 0.79%, which is meaningful compared to a plain S&P 500 index fund (which costs 0.03% or less) but is the price of the structured outcome. The fund trades at tight spreads on NYSE Arca, so entering and exiting is straightforward for most investors.

As of recent reporting, MARZ had roughly $17-18 million in assets under management, making it a relatively small fund. This size does not affect how the strategy works, but it does mean the fund is narrowly adopted—mostly by investors explicitly seeking the defined-outcome approach rather than buying MARZ by accident.

The appeal and the risks

MARZ appeals to investors who are weary of volatility or feel queasy during sharp market corrections. The 10% buffer means that a market drop to that depth is fully absorbed without a loss to the fund. For someone dollar-cost-averaging over years, this protection during downturns can reduce the temptation to sell at the bottom.

The downside is real: if the market rises more than the cap—say, 15% or 20% in a strong quarter—MARZ will not capture the full return. You profit, but less than a holder of the plain S&P 500 would. This is the deliberate trade. It also means that in a sideways or declining market, the fund’s expenses (0.79% annually) become more visible because there is little return to offset them.

Another risk is the quarterly reset. If the market is highly volatile within the three-month period, the payoff at expiry can be unintuitive. The fund’s return over the full quarter is locked by the options, but the intermediate price of the fund (which is set by market supply and demand for shares) can fluctuate significantly. If you trade MARZ at the wrong moment, you might lock in a loss even though the fund’s end-of-quarter structured payoff would have been profitable.

How to research MARZ

Investors interested in MARZ should begin with the fund’s prospectus and the latest fact sheet, which lay out the current quarter’s specific buffer level, upside cap, and option strikes. The fund’s annual report describes how often the buffer and cap are adjusted and what the historical experience has been.

Check the price action within the fund’s option expiry dates: MARZ tends to converge toward its intrinsic payoff as the roll date approaches. If you are buying or selling, understanding where you are in the quarterly cycle matters. The bid-ask spread on the fund is also worth observing to ensure you are not paying too much to get in or out.

For those comparing defined-outcome strategies, MARZ is one of several. Other products target the same idea with different indices, different buffer levels, and different reset intervals. Understanding the mechanics and the historical performance of your chosen fund is essential, because the outcome you receive is only as good as the options strategy written at the start of each period.
