Coulter Regal explains how buffer ETFs work, including buffers, caps, and defined outcome periods. He also covers the trade-offs investors should understand before using them.
Time in the market is what builds wealth over the long run, but sitting still through a downturn is harder than it sounds, and selling near the bottom is one of the most expensive mistakes an investor can make. Buffer ETFs were designed for that problem, so let's walk through how they work.
How Buffer ETFs Work
A buffer ETF uses options to reshape the return of a reference asset, usually the S&P 500, over a set period of time, most often one year. These funds are designed to absorb a set amount of the asset's losses, but in return, your upside is limited to a cap.
Because the buffer, the cap, and the time period are all known up front, these are called defined outcome strategies. The goal isn't to beat the market, it's to narrow the range of what can happen.
Potential Outcomes in Various Market Scenarios
Most buffer ETFs are defined by four things the reference asset they track, the size of the buffer they offer, the level of the cap, and the length of the outcome period.
Assume a fund has a twenty percent buffer. If the reference asset falls ten percent, then the fund seeks to finish flat rather than down ten. If it falls 30%, the first 20 is buffered and your loss would be the remaining 10%. And if the asset gains more than the cap, the fund would participate up to the cap, but not beyond.
That said, there are a couple of things to keep in mind. First, timing. The buffer and the cap are built for investors who hold for the whole period. Buy in halfway through, and both will look different than where the fund started.
Second, the cap. In a strong year, a buffer ETF's maximum return is limited by its cap. That's the trade-off for the downside protection of the buffer.
And third, this is not principal protection. You can still lose money. Once losses move past the buffer, they are borne one-to-one and passed through in full.
How Buffer ETFs Help Address Investor Concerns
So, why do investors use buffer ETFs? A large part of it comes down to behavior. When a set amount of loss is buffered, it becomes easier to remain invested through a period of market volatility.
Buffer ETFs also serve as a portfolio risk tool. Some investors use one in place of part of an equity allocation to help soften declines. Others move money out of cash or bonds to pursue more growth potential while still keeping a level of downside management. And some even use them when valuations feel a bit stretched, or if they're nearing retirement and want some downside management.
VanEck recently entered the buffer ETF space with a lineup of our own funds that offer buffered exposure to US equities whose outcome periods are staggered across the year so that investors can choose when to start or ladder positions over time.

Buffered outcome ETFs use investment strategies that differ from more typical products and may not be suitable for all investors. Before investing, please carefully read the prospectus to understand the funds’ strategies and associated risks.
The Funds seek to provide a buffer against the first portion of Underlying ETF losses and a cap on upside returns, but there is no guarantee these outcomes will be achieved, and an investor may lose their entire investment. Investors who purchase or sell Shares during an Outcome Period, rather than holding for the entire period, may experience returns very different from those a Fund seeks to provide. Please refer to each Fund's website, www.vaneck.com/JULV and www.vaneck.com/OCT, which provide updated information related to the remaining cap and buffer levels on a daily basis.
The Funds will not terminate after the conclusion of an Outcome Period. It is expected that, after the conclusion of an Outcome Period, a new Outcome Period will begin. The Outcomes may only be realized by investors who continuously hold Shares from the commencement of the Outcome Period until its conclusion.
The Fund’s Cap is likely to rise or fall from one Outcome Period to the next. If the Outcome Period has begun and a Fund has increased in value to a level near its Cap, an investor purchasing Shares at that price has little or no ability to achieve gains but remains vulnerable to downside risks. If the Outcome Period has begun and a Fund has decreased in value beyond its pre-determined Buffer, an investor purchasing Shares at that price may not benefit from the Buffer. Similarly, if the Outcome Period has begun and a Fund has increased in value, an investor purchasing Shares at that price may not benefit from the Buffer until the Fund’s value has decreased to its value at the commencement of the Outcome Period. An investment in the Funds is only appropriate for shareholders willing to bear those losses.
An investment in the Funds may be subject to risks which include, but are not limited to, risks related to the Funds' defined outcome strategy, FLEX Options, option contracts, derivatives, clearing member default, counterparty, underlying ETF, correlation, concentration, investment objective, liquidity, market, tax, investing in ETFs, active management, sub-adviser, affiliated fund investment, operational, authorized participant concentration, new fund, cash transactions, no guarantee of active trading market, trading issues, fund shares trading, premium/discount, liquidity of fund shares, non-diversified and valuation risks, all of which may adversely affect the Funds. The Funds' defined outcome strategy may entail other risks, such as buffered loss, capped upside return, outcome period, upside participation, cap change and buffer change risks. Underlying ETFs may entail other risks, such as equity securities, information technology sector and large-capitalization companies risks.
FLEX Options Risk. FLEX Options are customizable exchange-traded option contracts guaranteed for settlement by the Options Clearing Corporation (the “OCC”). The Fund bears the risk that the OCC will be unable or unwilling to perform its obligations under the FLEX Options contracts, and in the unlikely event the OCC becomes insolvent or is otherwise unable to meet its settlement obligations, the Fund could suffer significant losses. FLEX Options may also be less liquid than certain other securities, such as standardized options, and the Fund may have difficulty closing out certain FLEX Options positions at desired times and prices, which may adversely affect the value of your investment.
Investing involves substantial risk and high volatility, including possible loss of principal. An investor should consider the investment objective, risks, charges and expenses of the Fund carefully before investing.
