FT Vest Nasdaq-100 Moderate Buffer ETF - May (QMMY)

The FT Vest Nasdaq-100 Moderate Buffer ETF - May (QMMY) is a structured equity fund that tracks the Nasdaq-100 index while cushioning investors against losses of up to 10 per cent per year — a tradeoff designed to reduce volatility at the cost of capping the upside if the index rises more than about 15 per cent in a rolling twelve-month period.

The fund is issued by Vest Finance and tracks a structured index that combines the 100 largest non-financial stocks on the Nasdaq exchange. It is part of a family of “defined outcome” funds, a growing class of ETFs that use options strategies to artificially flatten the return profile of an underlying index. The shield resets each May, meaning the protection window and the cap run annually in sync with the calendar.

The buffer mechanics

The fund works by buying the Nasdaq-100 and simultaneously buying put options to protect against declines. The puts cost money — they are funded by selling call options that cap the upside. The specifics change each year because Vest rebuilds the trade on a set date.

In a typical low-volatility year, the protection is largely unused and the fund rises with the index, giving back about 0 to 3 per cent in call-sale premium forgone. In a sharp downturn — say a 20 per cent market fall — the puts pay off, limiting the fund’s loss to around 10 per cent. The cost, if the market instead surges 30 per cent, is that QMMY will lag, often capturing only a 15 per cent gain or slightly less.

This structure appeals to investors uncomfortable with the full swing of the stock market but unwilling to abandon equities entirely. It works well for those with low pain tolerance for drawdowns, particularly in retirement or near-retirement allocations. It works poorly for aggressive or very long-dated investors who can afford volatility and would rather capture the full upside.

Costs and the options overlay

The expense ratio is published by Vest and typically runs 0.75 to 0.85 per cent annually — more than a simple Nasdaq-100 index fund (which costs 0.20 per cent or less) but not unusual for an actively managed options strategy. The real cost is the ongoing tradeoff baked into the mechanics: cap realized on years when the index rises 15 per cent or more, protection unused in range-bound or slightly rising years, and the consistent drag from the options premium.

Because the fund is not a simple buy-and-hold index tracker, it carries annual rebalancing tax events that can create capital-gains distributions. Investors should hold it in tax-deferred accounts if possible.

Liquidity is generally reasonable — the fund is moderately sized and the underlying Nasdaq-100 is highly liquid — but it is considerably less actively traded than a vanilla Nasdaq-100 ETF. Bid-ask spreads can widen on days of sharp market movement.

What the buffer does not cover

The 10 per cent buffer applies only to the twelve-month period tied to the reset date. Investors who sell mid-year, or who hold through a multi-year bear market that spans two or more resets, will not experience the neat protection the name suggests. If the Nasdaq-100 falls 20 per cent in year one and another 15 per cent in year two, the fund does not protect against the second decline — each year’s buffer is independent.

The fund also does not insulate against tail-risk gaps — sudden overnight market collapses that jump past the floor. In extreme scenarios (historic crashes, geopolitical shocks, liquidity crunches), the option chain can fail to provide the full cushion promised.

Who this is for

QMMY suits investors who want the long-term growth profile of large-cap tech and growth stocks but are genuinely uncomfortable with the 30 to 50 per cent drawdowns that Nasdaq-100 holdings can experience. It is most natural in the portfolio of someone within ten years of retirement, or someone saving toward a goal with a specific timeline rather than a multigenerational horizon.

It is a poor fit for investors who trade frequently, those in taxable accounts without tax-loss harvesting discipline, or anyone who believes the Nasdaq will deliver exceptional returns — because the cap will bind, and they will have paid for protection they did not need.

Reading the prospectus

The prospectus contains the precise definitions of the buffer, the cap, the rebalance date, and the methodology for calculating both. It specifies whether the protection is per share or per investment, and it discloses the historical tracking error — the difference between the fund’s actual returns and what the formula promised. Investors should read the current-year prospectus and a copy from the prior year to understand how the terms reset and what changed.

The fund publishes daily holdings and the current state of the options overlay. Track the expense ratio year to year and watch the actual return profile — does the downside protection seem to be functioning, or are losses exceeding the stated buffer? Real-world tracking can drift from theory, especially in volatile periods.
