ROSC ETF: What Is It? A Complete Guide to Returns, Expense Ratio, Holdings and Alternative ETFs
The Hartford Multifactor Small Cap ETF, or ROSC ETF, is an index-tracking product that applies multiple factor criteria to US small-cap stocks. Investors can review valuation, quality and volatility characteristics together, along with risk factors related to quarterly distributions and dividends.
What Is the Hartford Multifactor Small Cap ETF?
The ROSC ETF tracks the Hartford Multifactor Small Cap Index, which reflects the performance of listed US small-cap stocks. The index determines its constituents and stock weights by considering low valuation, quality, momentum and low volatility factors together.
It may suit long-term investors who want diversified exposure across small caps while reflecting several investment characteristics rather than a single growth factor.
It is a passively managed (index-tracking) ETF run by Hartford Funds.

The ROSC ETF follows a rules-based index that combines relatively low valuations, quality characteristics such as profitability, and price momentum and volatility characteristics among small caps. Rather than relying on judgments about specific sectors or individual stocks, the strategy builds small-cap exposure using predetermined factor criteria.
- A small-cap index approach that reflects multiple factor signals together
- A rules-based construction that considers valuation and quality characteristics at the same time
Hartford Multifactor Small Cap ETF Size and Costs (AUM and Management Fee)
Assets under management (AUM) stand at $49.7M, and the total expense ratio is 0.34% per year.
For small-cap products, buying and selling costs can vary with trading conditions and market volatility. For a long-term holding, investors should look beyond the stated fee and also consider ease of trading, the potential for tracking error and the variability of distributions.
Hartford Multifactor Small Cap ETF Performance and Trends
The performance of the ROSC ETF can be influenced by investor appetite for small caps, valuation re-rating and shifts in economic expectations. A structure that reflects multiple factors can act as a cushion when a particular factor lags, but differences in performance between factors can also widen depending on the market phase.
Small-cap fund flows tend to react sensitively to risk appetite, liquidity conditions and the economic outlook. Because this product uses a rules-based index instead of picking individual companies, it is important to check the volatility of the small-cap asset class and the market liquidity environment before investing.
Hartford Multifactor Small Cap ETF Pros and Cons
Small-cap exposure that weighs several factors together is a strength, but the volatility inherent in small caps and changes in trading conditions need to be monitored continuously.

Hartford Multifactor Small Cap ETF Alternatives and Related Products
The products shown in the table have different investment themes, so they should be compared by exposure objective rather than viewed as simple direct substitutes. The XT ETF focuses on future technology themes, while the KOMP ETF broadly covers new economy growth themes. The MOO ETF concentrates on agriculture-related companies, the NUKZ ETF on the nuclear power industry, and the KSTR ETF on Chinese technology and semiconductor themes. The ROSC ETF, by contrast, reflects multiple factors within US small caps, so theme concentration, fee burden, asset size and distribution characteristics should be compared separately.

Hartford Multifactor Small Cap ETF Investor Checkpoints
Before investing in the ROSC ETF, investors should first confirm the role small-cap exposure will play in their overall asset allocation and understand the characteristics of a multifactor strategy. Rather than judging future cash flows from distribution history alone, it is advisable to review the index construction principles, trading environment and long-term holding objectives together.
| Checkpoint | What to Check | Current Status |
|---|---|---|
| Fee burden | Check how costs accumulate over a long holding period | Comparison needed |
| Index methodology | Check the characteristics of the multiple factor signals and inclusion rules | Check official materials |
| Small-cap weighting | Assess what share of total assets can absorb small-cap volatility | Check risk tolerance |
| Distribution policy | Check the quarterly distribution record and potential for change | May vary |
Small caps can be at a disadvantage to large caps in terms of liquidity and business stability, and price pressure can intensify during economic slowdowns or risk-averse phases. A multifactor strategy also does not guarantee defensiveness in every market environment, so the index tracking method and currency exposure should be considered as well.
The ROSC ETF is a passive product for investors who want to access US small caps while reflecting multiple factors. Unlike single-theme products, its core feature is small-cap factor exposure, so it is appropriate to confirm that the investment objective and tolerance for volatility are aligned, and then review it from a long-term asset allocation perspective.
