State Street SPDR S&P 500 ETF Trust vs Vanguard S&P 500 ETF
VS
Comparative Analysis
VOO wins this head-to-head comparison due to its lower expense ratio and superior long-term trailing returns, making it the more cost-effective choice for investors seeking broad market exposure. While both SPY and VOO offer similar exposure to the S&P 500, VOO's lower fees translate to better net performance over time. SPY's slightly higher expense ratio, though marginal, compounds over longer periods, eroding investor returns. Investors prioritizing cost efficiency and maximizing long-term gains will find VOO to be the more compelling option.
Key Differentiator
The key differentiator between SPY and VOO is VOO's significantly lower expense ratio (0.03% vs. 0.095%). This cost advantage translates directly into higher net returns for investors over the long term, making VOO the more efficient and cost-effective choice for gaining exposure to the S&P 500 index.
Joint Outlook
The outlook for both SPY and VOO remains closely tied to the performance of the broader U.S. equity market and the S&P 500 index. Given their current positioning near 52-week highs and positive technical indicators, a continuation of the upward trend is plausible, supported by strong corporate earnings and favorable macroeconomic conditions. However, potential headwinds such as inflation, rising interest rates, or geopolitical tensions could trigger market volatility and pullbacks. In a bull case scenario, both ETFs could see further gains, with VOO outperforming SPY due to its lower fees. In a bear case, both would decline, with the magnitude dictated by broader market forces.

VOO presents a more attractive valuation proposition primarily driven by its significantly lower expense ratio of 0.03% compared to SPY's 0.095%.

Technical rating: based on current price action versus moving averages and momentum. This measures short-term chart trend, not analyst opinion or company fundamentals.
SPY
Technical Score: 75/100
VOO
Technical Score: 75/100
As SPY and VOO are index ETFs, they do not have analyst ratings or median price targets in the traditional sense. Sentiment is primarily driven by market-wide trends and investor flows into broad market exposure. The current technical indicators for both ETFs, such as RSI and CCI, suggest positive market sentiment. Investor demand for broad market exposure, as evidenced by their substantial net assets (SPY: $811.9B, VOO: $1.74T), indicates a generally favorable view of the U.S. equity market.
Risk Stratification
| Metric | SPY | VOO |
|---|---|---|
| Sharpe Ratio | 0.73 | 0.76 |
The primary risk for both SPY and VOO lies in broad market downturns, as they are designed to mirror the S&P 500 index. A significant economic recession, geopolitical instability, or a sharp rise in interest rates could lead to substantial declines in their value. SPY's slightly higher expense ratio presents a minor, compounding risk over time, meaning investors will underperform VOO by the fee differential if market returns are equal. However, the core risks are identical: systemic market risk and sector-specific downturns within the index.
Comparative ProTips
- Prioritize VOO over SPY for long-term S&P 500 investments due to its lower expense ratio, which enhances net returns.
- Monitor the expense ratios of ETFs regularly, as even small differences can significantly impact portfolio performance over extended periods.
- Consider the inception date of ETFs; while SPY is older, VOO's lower fees have made it a preferred choice for many investors seeking cost efficiency.
