Built on exposure to the Russell 2000, the benchmark index for US small caps, this ETF pursues a buffer strategy that cushions downside losses within a set range and, in exchange, places a cap on upside. Its defining feature is a ladder structure that combines buffer ETFs with different maturities at equal weights.

It suits investors who want to invest in small caps while softening downside volatility during sharp declines to some degree.

It is an actively managed ETF operated by First Trust.

Through a ladder structure that holds small-cap moderate buffer ETFs of various maturities at equal weights, the fund spreads out a defined outcome strategy that cushions downside losses within a set range while capping upside. It is designed to avoid concentration in a single maturity, so the buffering effect is delivered evenly throughout the year.

• A ladder structure combining multiple maturities reduces dependence on the entry point
• A defined outcome design that pairs small-cap exposure with a buffer strategy

Assets under management (AUM) stand at $197.3M, and the expense ratio is 1.01% per year.

The buffer and cap vary with the defined outcome period of each underlying ETF, and at the fund level they work as an average buffering effect.

The fund moves in line with the small-cap market, but its downside buffer structure tends to reduce the magnitude of losses during sharp declines. During rallies, however, the cap may prevent it from capturing the full gains of the underlying index.

When volatility rises, demand for downside protection tends to increase interest in buffer strategy ETFs. Conversely, in bull markets, the cap structure sometimes shifts investor preference toward standard small-cap ETFs.

Its strengths are the downside buffer and timing diversification, while the upside cap and the fee burden of an active structure are the main drawbacks.

The three tickers shown in the table, BUFR, BUFD, and BUFQ, are laddered buffer ETFs from the same First Trust family, and they differ in underlying exposure and buffer strength: a standard buffer on large caps, a deep buffer, and Nasdaq exposure, respectively. SFLR and PJAN are buffer strategy ETFs from other issuers and can be considered for comparison. Meanwhile, investors who want uncapped exposure to the small caps underlying this ETF can also look at IWM, which tracks the Russell 2000.

These are the points to review before investing in BUFS. Alongside the benefit of a downside buffer, it is important to understand in advance the upside cap, the fee burden of active management, and the buffer limit, meaning that a buffer cannot prevent every loss.

The buffer softens losses only within a set range, and the fund remains exposed to steeper declines beyond it. In addition, the upside cap and active fees can affect long-term returns, so it is necessary to understand how the buffer structure works before investing.

It is an option worth considering for investors who want to combine small-cap exposure with a downside buffer. If you prefer pure small-cap exposure without a cap, we recommend comparing alternatives such as IWM, and if large-cap buffering is the goal, BUFR.
