To trade the S&P 500, we can choose between SPY and SPX. These two products are perfectly correlated but have differences in other factors, which typically have us lean towards using SPY. Today, tastytrade explains why.
The higher notional value and lower commission fees of SPX often lures traders with large amounts of capital. Based on our study, however, this is not a wise choice. SPX has a much higher bid/ask spreads compared to SPY and the total cost of commission and slippage is more than two times higher for SPX.
