The Only S&P 500 ETF You Need in 2026 and It's Not the One You Think

SPDR S&P 500 ETF (SPY) remains the default S&P 500 vehicle due to first-mover status and dominant options liquidity, but its structure and costs mean buy-and-hold investors pay more each year than they would with lower-cost S&P 500 ETF alternatives. For portfolio managers, evaluate core long-only S&P exposure against lower-fee ETF share classes and consider allocating to SPY selectively for options/liquidity needs rather than as the default buy-and-hold vehicle. This is a cost-efficiency/implementation issue with limited market-moving implications.
