What this means for investors
Clearly, not all index funds are built the same. Choosing which one to buy is an important decision, since it’s likely going to be the one you are going to use to grow your wealth for decades. Minor cost differences, as measured by the expense ratio, can add up over time.
IVV’s higher dividend yield is certainly a bonus, but investors shouldn’t make the yield their deciding factor. Yields can fluctuate with changes in price and sector weightings in these funds’ holdings. The expense ratio is where the rubber meets the road.
The value of selecting the fund with the lowest expense ratio is evident in looking at past returns. Over the last five years, IVV returned 81.12% (including dividends), beating SPY’s gain of 80.52%. Going back 10 years, the difference widens a bit further, with IVV up 280.9% to SPY’s 278.8%.
As long as IVV’s expense ratio is lower, that return difference will continue to widen over many years. For example, a $50,000 investment in IVV at its 2000 inception would be worth $371,140 today, compared to $357,230 in SPY. IVV would have made an investor $13,910 richer.
The cost difference is the single most important difference between these index funds. SPY usually gets all the attention since it has been around the longest. Still, IVV’s lower expense ratio gives it a massive edge in delivering superior returns to investors over the long term.
