For passive investors, it's the best of times: They're seeing new highs on the two major cap-weighted indexes — S & P 500 and the Nasdaq Composite — with low volatility. One example is the Invesco S & P 500 Momentum ETF (SPMO) , which tracks the S & P 500 Momentum Index. That index follows the performance of stocks in the S & P 500 that have a high "momentum score." Momentum ETFs in 2024 S & P 500 up 18.1% Invesco S & P Momentum ETF (SPMO) up 39.9% iShares USA Momentum Factor (MTUM) up 28.5% Both ETFs also have concentrated bets. Why momentum is a risky strategy Let the buyer beware: Everyone looks like a genius holding on to winners in up markets.
