SPMO (SPDR® Portfolio S&P 500 Momentum ETF) is passively managed. It tracks the S&P 500 Momentum Index, which is designed to provide exposure to large-cap U.S. stocks that have exhibited positive momentum characteristics. Being an index-based ETF, it is passively managed to replicate the performance of that index, rather than actively selecting securities.
SPMO (Invesco S&P 500® Momentum ETF) is not a passively managed ETF in the traditional sense. It is factor-based and follows a smart beta strategy, which focuses on companies in the S&P 500 that exhibit strong momentum characteristics. While the ETF is designed to track the S&P 500 Momentum Index, the underlying methodology involves selecting stocks based on specific criteria (momentum), making it more of a rules-based active management approach, though it isn't actively stock-picking like a traditional actively managed fund.
