The Invesco S&P Intl Developed Momentum ETF (IDMO) offers disciplined, rules-based international momentum exposure, diverging from traditional market-cap-weighted ETFs. I rate IDMO a BUY for investors seeking dedicated momentum exposure or to complement broad international ETFs, as long as they can accept higher turnover, concentration, and tracking error. IDMO's adaptive sector allocation currently favors Financials and Industrials, with a 3.45% yield driven by recent momentum trends and a 0.25% expense ratio.
