SPYM has the lowest total cost among S&P 500 ETFs
The S&P 500 remains a reliable long-term investment strategy, with an average annual return of around 10% over the past century.
The index has four major ETFs: VOO, IVV, SPY, and SPYM, all with ultra-low expense ratios and virtually identical performance records.
For investors, the key differentiator is cost, with SPYM having the lowest total cost, making it a slight advantage over the others.
The total cost is a combination of the expense ratio and the trading cost incurred whenever a trade is made.
