Overview
The Vanguard S&P Small-Cap 600 Index Fund ETF Shares, trading under the ticker VIOO, operates within the US Small Cap category managed by issuer Vanguard. This fund holds an overall rank of #109 out of 458 tracked ETFs across all categories and has received an ETFValuer grade of B with a score of 69.8 out of 100. With assets under management totaling $6.41 billion and a current price of $135.67, the fund demonstrates significant investor adoption relative to the 18 ETFs tracked in its specific category. The fund offers a low-cost structure with an expense ratio of 0.07% while providing a dividend yield of 1.10%. These metrics position VIOO as a substantial, cost-efficient vehicle within the small-cap space, reflecting broad market participation. The combination of high assets and a moderate expense ratio suggests established utility for investors seeking exposure to this segment.
Over the most recent trading day, the fund posted a return of +0.57%, though it experienced a slight decline of -0.18% over the past week. Monthly performance showed a contraction of -0.64%, contrasting with a stronger recovery and growth of +7.56% over the three-month period. The six-month return accelerated further to +14.62%, building upon a year-to-date gain of +21.05%. This upward trajectory continued into the one-year horizon with a return of +31.30%, while the three-year return stands at +47.92%. The data indicates a pattern where short-term fluctuations have given way to sustained positive momentum over longer holding periods. Recent performance shows a clear divergence between the immediate monthly dip and the robust gains recorded over the year and three-year marks.
VIOO carries a Moderate volatility label and exhibits a beta of 1.08, indicating that its price movements tend to be slightly more sensitive to market shifts than the broader benchmark. The fund has experienced a maximum drawdown of -27.93%, reflecting the potential for significant temporary declines during market stress. Despite these fluctuations, the Sharpe ratio of 1.51 suggests that the returns generated have been efficient relative to the level of risk taken. This combination of a beta above 1.0 and a substantial drawdown implies the fund amplifies market movements, yet the high Sharpe ratio indicates strong risk-adjusted performance over the measured period. Investors should expect behavior that mirrors the volatility of the US Small Cap category with a slight premium in sensitivity.

VIOO Liquidity, Domicile & Tax Treatment
Liquidity: Quoted bid/ask spread is — and average daily volume is 77K/day. Tighter spreads and higher volume mean lower round-trip trading costs; this is a live-market snapshot and can widen during volatile sessions. AUM of $6.41B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.
Domicile & tax treatment: VIOO is a US-domiciled, SEC-registered ('40 Act) exchange-traded fund. Dividends and capital gains distributions are reported to US investors on Form 1099-DIV, and the fund is not subject to the PFIC reporting or UCITS-specific rules that apply to Irish- or Luxembourg-domiciled funds. Non-US investors should note that US-domiciled ETFs are generally subject to 30% US withholding tax on dividends (unless reduced by treaty) and to US estate tax exposure on the position — Irish-domiciled UCITS ETFs tracking the same index often avoid both, which is why non-US residents frequently prefer the UCITS equivalent where one exists. This is general information, not tax advice — consult a tax professional for your situation.
