FT Vest U.S. Equity Dual Directional Buffer ETF - May (DLMY)

The FT Vest U.S. Equity Dual Directional Buffer ETF - May (DLMY) is an exchange-traded fund built on a novel premise: that investors might prefer knowing their maximum loss in advance to enduring the uncertainty of open-ended equity ownership. DLMY attempts this through options mechanics, delivering a named outcome tied to the S&P 500 over a one-year period that resets every May.

The structural innovation behind target-outcome funds

DLMY belongs to a newer category of ETFs that invert the traditional investment premise. Rather than asking “how much can I make?” and accepting whatever loss follows, target-outcome funds ask “what outcome do I want?” and engineer a portfolio of options to achieve it. This represents a subtle but significant shift in who bears the risk and how transparency enters the investment contract.

DLMY specifically is the May variant of First Trust’s dual-directional buffer series. The “dual directional” label is key: unlike a standard protective strategy that only guards against losses, DLMY attempts to profit from both upside and moderate downside movement. The “buffer” component sits on top of that—a cushion against severe losses that might otherwise overwhelm the portfolio.

The mechanics: collar strategy in practice

At its core, DLMY implements what options traders call an “iron butterfly” or, more accurately, a “collar with a twist.” The fund holds positions in exchange-traded FLEX options on SPY, structured to deliver three outcomes over its May-to-May outcome window.

First is the upside cap. For the current outcome period, that cap is set at a specific percentage—typically in the 10–13% range before fees, lower after subtracting the 0.85% annual cost. If SPY rises 30%, an investor in DLMY does not capture that full gain; they receive only the capped amount. This cap is how the fund affords the other two legs of the strategy.

Second is the inverse leg. This is where DLMY differs from simple downside-protection funds. If SPY declines by up to 10%, DLMY does not lose money; instead, it attempts to generate a positive return by capturing the absolute value of that decline. This works because the fund has sold (shorted) certain options positions that become profitable when markets fall. The inverse participation is also capped—typically at 10% gain if the underlying asset declines by 10%.

Third is the buffer. Any decline in SPY beyond the 10% threshold triggers the buffer. If SPY falls 15%, the buffer absorbs the first 10 percentage points, and DLMY loses only 5%. If SPY falls 25%, DLMY loses 15%. The buffer does not eliminate loss; it delays it. The idea is that investors willing to hold for the full year can accept a 10% downside cushion in exchange for exposure to both upside (capped) and moderate-downside profit potential.

Why the May cycle matters

DLMY’s outcome period runs roughly from May 20 of one year to May 19 of the next. This timing choice is arbitrary in one sense—First Trust could have chosen any month—but consequential in another. It means that every holder whose shares are held to maturity experiences the same outcome cycle. The options contracts expire on the same day; positions are closed; cash is distributed or returned; and a fresh one-year outcome period begins with newly written options set to the next May.

An investor buying DLMY in March has already surrendered about two months of the nine-month upside opportunity and is betting that the May outcome period remains favorable. An investor buying in August is halfway through and is essentially purchasing an option-based derivative with a known termination date rather than participating in the full engineered outcome.

Expense ratio and the cost of optionality

At 0.85% annually, DLMY’s fee is roughly 25 times higher than a plain S&P 500 index ETF. That cost buys the active management required to maintain the collar, the sophistication needed to adjust the hedges as markets move, and the operational overhead of running a fund with perpetually resetting options contracts. It also prices in the bid-ask spread and slippage the fund incurs when executing option trades.

Whether that cost is justified depends on the investor’s time horizon and loss aversion. In a rising market, the cost compounds—you miss meaningful gains due to the cap, and you pay the fee for the privilege. In a falling or sideways market, the cost may be easily recouped if the buffer and inverse leg protect capital or generate returns.

Positioning within the First Trust suite

DLMY is one of four (or more) variants of the dual-directional buffer strategy reset on different months. DLAG targets August, DLFE targets February, DLNV targets November, and DLMY targets May. A sophisticated investor might stagger purchases across multiple outcome periods—buying $10,000 of each in January, April, July, and October—to ladder outcomes and reduce the concentration risk of betting the entire portfolio on one May-to-May cycle.

First Trust also offers variants with different buffer levels or inverse caps, though the core mechanics remain consistent.

Risks and limitations that are rarely discussed

The primary risk is path dependency. The outcome formula assumes you hold to the May expiration. Selling mid-year means you are accepting the fund’s market price, which could be substantially different from the intrinsic outcome value if volatility has shifted or if the underlying options have moved significantly against you. There is no secondary market liquidity guarantee for DLMY; as a narrowly focused structured product, spreads could widen sharply if many holders try to exit at once.

A second risk is that the inverse leg and buffer depend entirely on the fund’s ability to execute the options hedge flawlessly. If the options markets seize up, or if index volatility spikes to levels not priced into the FLEX contracts, the fund’s actual outcome could diverge materially from the stated terms. Historical precedent exists for this (VIX spikes in 2018, 2020), though modern circuit breakers have made true market seizures rarer.

Finally, there is tax complexity. The daily rebalancing of the collar and the turnover within the options positions can trigger capital gains, making DLMY a poor choice for taxable accounts without careful monitoring. Tax-deferred accounts (IRAs, 401(k)s) are more natural homes.

How readers can evaluate DLMY

Start with the prospectus on First Trust’s website. It contains the precise upside cap, inverse cap, buffer level, and expense ratio for the current outcome period. Track the fund’s price relative to SPY throughout the cycle. Compare the fund’s actual return at the next May expiration to what the published outcome promised. If there is a pattern of outcomes beating their published terms, DLMY is executing well; if they lag, the costs and rebalancing inefficiencies are eating into returns.

Also consider whether a simpler alternative—a 60/40 stock-bond portfolio, a put-protected equity position, or a 10-year Treasury ladder—achieves comparable downside protection at lower cost. DLMY is a legitimate tool, but it is not the right tool for every investor or every market regime.
