This is a defined outcome ETF that gains exposure to a US equity index while using options to protect against a set range of losses. Over a one-year outcome period, it cushions a certain amount of decline in exchange for a cap on upside returns, and the structure is reset every February.

It suits moderate-risk investors who want to invest in US stocks, accept a cap on gains, and receive protection against a set range of declines.

It is a passive (index-tracking) ETF managed by First Trust.

The fund gains exposure to a US equity index and uses an options structure to cushion a set range of declines over the one-year outcome period, in exchange for a cap on upside returns. A new buffer and cap are set every February, and buying partway through an outcome period can change the protection and cap that apply.

• Structure that cushions a set range of declines
• Defined outcome design with a cap on gains

Assets under management (AUM) stand at $372.1M, and the total expense ratio is 0.85% per year.

Compared with other buffer and defined outcome ETFs such as BUFR and BUFD, the main points of comparison are the level of protection, the cap level, and the outcome period.

Buffer strategies tend to see returns limited relative to the underlying index in rising markets because of the cap, while declines are reduced in falling markets as a set range of losses is cushioned. The protection and cap that actually apply depend on whether you enter partway through the outcome period.

Defined outcome products tend to attract inflows from investors seeking downside protection when market uncertainty rises, and money sometimes moves into this product category when interest in volatility management increases. It is also worth noting that performance varies with market conditions and the outcome period.

Its strength is a defined cushion against declines, while the upside cap, dependence on the outcome period, and changing conditions for mid-period entry are factors to consider.

For direct exposure to US stocks without protection, the S&P 500 ETFs SPY and VOO are straightforward substitutes, and for a laddered buffer that spreads across several outcome periods, products such as BUFR are also worth comparing. Buffer products with a different start month, such as GMAY, can be considered as well. The three products shown in the table, BUFR, BUFD, and PJAN, differ in protection level and structure: a laddered buffer, a deep buffer, and a buffer with a different start month, respectively. What sets this ETF apart is its February-based defined outcome buffer structure.

These are the points to review before investing in GFEB. The downside cushion is attractive, but the upside cap, dependence on the outcome period, and the limits of the buffer should be checked in advance. It is best to approach the fund only after fully understanding the defined outcome structure.

The cap in strong rallies and large declines that exceed the buffer are the main variables for performance, and buying partway through the outcome period changes the protection and cap that apply. Without a full understanding of the defined outcome structure, you may end up with results that differ from your expectations.

It is a suitable candidate for moderate-risk investors who want to invest in US stocks while being protected against a set range of declines. If you want to invest without protection, consider products such as SPY and VOO. If you want a defined outcome buffer structure, it is advisable to choose this product after understanding how it works.
