This is an actively managed ETF that invests mainly in US small-cap stocks within the market capitalization range of the Russell 2000 Index. Rather than simply tracking an index, the management team actively selects stocks based on growth potential.

It suits growth-oriented investors who want exposure to US small caps through active selection rather than simple index tracking, and who are willing to tolerate high volatility.

It is an ETF run with an active (actively managed) approach by SEI.

The fund invests most of its net assets in US small-company stocks that fall within the market capitalization range of the Russell 2000 Index, and the management team actively selects stocks based on growth potential and fundamentals. Instead of simply tracking an index, it pursues long-term excess returns in small caps through proactive stock selection.

• Active selection of US small caps
• Active management rather than index tracking

Assets under management (AUM) stand at $630.3M, and the total expense ratio is 0.55% per year.

Compared with simple index-based small-cap ETFs, the main points of comparison are its active selection approach and its stock concentration.

US small caps react sensitively to the economic cycle, interest rates, and risk appetite. They tend to outperform large caps during economic recoveries and fall harder during economic slowdowns. Because of its active selection structure, the fund's performance may diverge from the market average.

Fund flows in small caps diverge sharply depending on risk appetite and the economic outlook, and money sometimes moves into small caps when expectations of an economic recovery grow. Given the nature of an active strategy, it is also worth noting that fund flows can depend on management performance.

Active stock selection is its strength, while the high volatility typical of small caps, active management fees, and liquidity are points to consider.

Direct substitutes for simple index-based small-cap exposure include lower-fee options such as IWM and IJR, and for those who want to focus on small-cap value stocks, products like AVUV and VBR are also worth comparing. The three products shown in the table, HELO, FHEQ, and INFO, differ in investment target and strategy, using option hedging and large-cap core strategies respectively, so they serve more as reference points than direct comparisons. The distinguishing factor of this ETF is its active management, which selects US small caps actively.

Here are the points to review before investing in SEIS. Active selection is the appeal, but high volatility, liquidity, and management fees need to be confirmed in advance. It is also a good idea to compare it with simple index-based small-cap products.

Drawdowns during economic slowdowns and risk-averse phases, along with shrinking small-cap liquidity, are the main variables for short-term performance, and an active selection strategy can see its results diverge from the market average depending on the period. Investors should be mindful of the high volatility typical of small caps.

It is a suitable candidate for growth-oriented investors who want to invest in US small caps through active selection. If cost and simple index tracking are the priority, consider products like IWM and IJR; if you trust active small-cap selection, it is advisable to compare this product alongside them before choosing.
