What this ETF is trying to do

The Harbor Active Small Cap ETF (SMLL) is designed to invest in small-company stocks. Unlike some funds that follow a strict list, this is an "active" ETF, meaning managers choose specific stocks they believe will perform well. Based on its top holdings, the fund invests in a variety of businesses, including Pool Corp (5.33%), WillScot Holdings Corp (4.52%), and Wintrust Financial Corp (4.00%).

What the numbers show

As of October 9, 2026, the share price of SMLL was $20.55. To understand how the price has moved, we can look at two different types of returns:

• Price Return: This measures only the change in the share price. The one-year price return was -1.87%, and the year-to-date (YTD) price return was 3.16%.

• Total Return: This measures the overall return, including the cash distributions paid to investors. The one-year total return was 0.43%, and the YTD total return was 3.16%.

For a simple example, if an investor had put $10,000 into the fund based on the estimated price from roughly one year ago ($20.94), the price-only change would have resulted in a slight decline in the value of those shares.

Income and distribution explanation

SMLL provides cash distributions to its investors. The distribution yield is approximately 2.30%. Over the last 12 months, the fund had one payout, and the distribution frequency is described as irregular or less frequent.

It is important for beginners to remember that a distribution yield is not the same as a total return. While distributions provide cash income, they do not guarantee that the original investment (the principal) will stay the same or grow.

NAV erosion explanation

The supplied data is sufficient to evaluate price erosion, but it does not include enough historical NAV-per-share data to confirm or rule out NAV erosion.

However, looking at price-based evidence, the fund has an erosion-risk score of 94, which is labeled as "Stable / sideways" with "good" severity. Additionally, the severe erosion-risk flag is false, meaning the fund's price trend did not trigger a high-risk warning.

Pros

• Stability: The erosion-risk score suggests the price has remained relatively stable.

• Diversification: The fund holds 51 different companies across various industries.

• Positive YTD Growth: Both price and total returns are positive for the current year.

Cons

• Negative One-Year Price Return: The share price alone declined by 1.87% over the last year.

• Irregular Income: Because payouts are irregular, investors cannot rely on a steady, predictable monthly or quarterly check.

Beginner takeaway

SMLL is a fund for those who want exposure to small-cap companies. While it offers a modest distribution yield, the income is not frequent. The most important thing to note is the difference between the one-year price return (which was negative) and the one-year total return (which was slightly positive), showing that distributions helped offset the dip in share price.
