IDMO Brings Momentum Factor to International Stocks

Investors enjoying the pairing of domestic stocks and the momentum factor are likely familiar with some related ETFs. This includes the Invesco S&P 500 Momentum ETF (SPMO).

SPMO is an $11.6 billion titan that turns 10 years old in October. It’s an ETF that can significantly outpace the broader market when the momentum factor is in style. For the three years ending August 18, SPMO returned nearly 115%, while the S&P 500’s gain was closer to 59%.

Impressive stuff to be sure, and those data points beg the question, “Is there an international answer to SPMO?” Yes — the Invesco S&P International Developed Momentum ETF (IDMO). This fund, which tracks the S&P World Ex-U.S. Momentum Index, doesn’t garner the attention its domestic stablemate does. But that belies the facts that IDMO is neither new nor small. The ETF turned 13 years old in February, and has $1.49 billion in assets under management.

Investigating IDMO Advantages

While IDMO flies under the radar relative to SPMO, the former keeps with the latter’s tradition of delivering the goods when the momentum factor is thriving. Over the past three years, IDMO surged 81.8%, easily trouncing the 51% returned by MSCI EAFE Index.

Year-to-date, IDMO returned 32.3% as of August 18. That’s because in 2025, momentum with ex-U.S. developed market stocks has largely meant exposure to European equities and the financial services. Those two are boxes checked by the Invesco ETF.
