This ETF uses a U.S. small-cap index as its underlying asset and has a defined outcome structure: it buffers a set range of losses during the outcome period and captures gains only up to a predetermined cap. The outcome period begins in November and resets on an annual basis.

It suits investors who want small-cap exposure, would like to soften volatility during sharp declines, and can accept a cap on upside.

It is an actively managed ETF run by Innovator Capital Management.

The fund combines FLEX options linked to the underlying small-cap index to provide a set buffer against declines during the outcome period. In exchange, it captures upside only up to a predetermined cap. The buffer and the cap are set at the start of the outcome period, and the designed outcome is approached only by holding through to the end of the period.

• Predetermined downside buffer range
• Options-based structure with an upside cap

Assets under management (AUM) are $42.9M, and the expense ratio is an annual 0.79%.

Because the buffer and the upside cap are set at the start of the outcome period, buying partway through the period may mean the buffer and cap levels differ from those at the beginning.

The fund moves with the small-cap market, but in down markets the buffer reduces the drawdown relative to the underlying asset, and in up markets additional gains are limited as returns approach the cap. The performance an investor actually experiences varies depending on where they enter within the outcome period.

When market volatility rises, interest in buffer products tends to emerge on demand for downside protection, and the direction of fund flows may differ depending on small-cap direction and the interest rate environment.

Its strength is that the downside buffer lowers the burden of volatility, while the upside cap and the requirement to hold to the end of the period act as constraints.

Comparable products in the same buffer and defined outcome category, as shown in the table, include BUFR, BUFD, BUFQ, PJAN, and SFLR. They differ in underlying index, buffer size, issuer, and fee structure. Among them are products with different underlying assets and buffer approaches, such as ladder structures that stack multiple maturities, Nasdaq-based products, and large-cap-based products. For direct small-cap exposure without a buffer, a product tracking a U.S. small-cap index such as IWM can be considered as an alternative. When choosing a buffer product, it is important to compare the underlying asset, reset timing, and fee differences together.

Here are the points to review before investing in KNOV. For buffer-structure products, it is important to check in advance the remaining buffer, the upside cap, and your position within the outcome period, and to keep in mind that the actual buffer and cap levels may differ depending on your purchase date.

The upside cap limits returns in strong markets, and buying mid-period may mean the buffer and cap differ from the original levels. Small-cap volatility can also lead to losses once declines exceed the buffer range.

It may be worth considering for investors who want small-cap exposure while softening part of the downside volatility. For direct exposure without a buffer, a small-cap ETF such as IWM may be more suitable.
