The short version

How SPY and VOO compare today, and what CleaRank Financial AI makes of it.

The verdict

SPY and VOO on the figures that matter most, and which one CleaRank Financial AI prefers today.

CleaRank Financial AI favours VOO
SPY VOO
75/100 AI score 75/100
+14.9% 1-year change +14.9%
10.9% Volatility (30d, yearly) 11.2%
43.8 RSI (14-day) 43.7
The verdict
VOO wins this head-to-head comparison against SPY, primarily driven by its superior valuation due to a significantly lower expense ratio. While both ETFs track the broad U.S. equity market and exhibit similar technical and profitability profiles, VOO's cost advantage translates to better long-term net returns for investors. For cost-conscious investors seeking broad market exposure, VOO presents a more compelling choice.
Key difference
The decisive factor separating SPY and VOO is their expense ratio. VOO's significantly lower expense ratio of 0.03% versus SPY's 0.095% translates to a direct cost saving for investors. This difference, while seemingly small, compounds over time and is a critical differentiator for long-term wealth accumulation, making VOO the more cost-efficient choice for broad U.S. equity market exposure.
Outlook
The outlook for both SPY and VOO is largely tied to the performance of the broader U.S. equity market over the next 6-12 months. Given their similar technical profiles and sector concentrations, they are expected to move in tandem. A scenario of continued economic expansion and stable interest rates would likely see both ETFs trend higher, with VOO's lower fees providing a slight performance edge. Conversely, a market downturn driven by inflation concerns or recessionary fears would impact both negatively, though VOO's cost efficiency would remain a persistent advantage.

10.9% Volatility (30d, yearly) 11.2%
0.83 Sharpe ratio 0.86
Risk
The primary risk for both SPY and VOO lies in the overall performance of the U.S. equity market, which is heavily influenced by macroeconomic factors, interest rate policies, and geopolitical events. As large-blend ETFs, they are exposed to significant concentration in the Technology sector, making them vulnerable to downturns in that specific industry. SPY's slightly higher expense ratio presents a minor, ongoing drag on returns compared to VOO. Both funds are susceptible to market volatility, as indicated by their similar technical readings suggesting a lack of strong upward momentum and prices trading below short-term averages.
ProTips
  1. Prioritize VOO over SPY for long-term investments due to its significantly lower expense ratio, which directly enhances net returns.
  2. Monitor the Technology sector's performance closely, as it represents a substantial portion of both ETFs' holdings and can drive significant volatility.
  3. Consider the slight difference in dividend yields, but recognize that VOO's cost advantage is a more impactful factor for overall wealth accumulation.
