Small-caps are also focused on the domestic economy and have less direct exposure to global geopolitical uncertainty and currency risks, as opposed to large-cap companies that have an international footprint, which may be affected by overseas risks and a strengthening U.S. dollar.

Following Election Day, investors flocked to IWM, IJR and rival small-cap ETFs as markets priced in President Donald Trump’s “America First” mantra that would help domestically-oriented companies led the next leg in economic growth.

Expansionary fiscal policies have fueled inflation expectations, which have in turn raised bets on a Federal Reserve interest rate hike and strengthened the U.S. dollar. Consequently, with a stronger U.S. dollar, large-cap stocks may underperform as many large exporters find it harder to sell goods to foreign markets.

Jonathan Krinsky, chief market technician at MKM Partners, “noted that a buying opportunity could be near given its oversold conditions. In measuring market breadth — the number of stocks pulling back relative to the number of stocks advancing — small caps appear to be their most oversold since January 2016, he said,” reports CNBC.

Flows to big small-cap ETFs are mixed to start 2017 as IWM has bled $2.92 billion while IJR has seen $3.2 billion in inflows.
