When we look at the annualized returns, both these ETFs perform very similar to the benchmark, with VOO performing slighter better.
Conclusion – Is there really a difference?
From the findings above, both funds perform very similar. This is no surprise as they both track the same index. So then, which one should you buy?
If you are buying for very long term investment, I would go with VOO, because of the lower expense ratio. This is how much you will be paying fees assuming you invest $100k at a 7% return every year for the next 20 years.
You will be paying double in fees for SPY compared to if you invested in VOO.
However, if you don’t plan on holding long term, and is looking to do more trading, then SPY might be a better choice because of the higher trading volume. When you are trading, every little bid/ask spread will translate into profit or losses for you. The expense ratio won’t make much difference to you in this scenario.
As always, remember that Past Performance is No Guarantee of Future Results.
