The largest actively-managed emerging-market ETF saw a dramatic surge in investor inflows following the Supreme Court's decision to strike down President Trump's global tariffs, signaling renewed appetite for risk assets in developing economies.

This inflow spike comes as markets react to the removal of trade barriers that had previously dampened emerging-market sentiment. The ETF's performance highlights how quickly investor confidence can shift when major policy obstacles are removed, with capital flowing back into regions previously considered vulnerable to trade tensions.

The surge demonstrates the market's sensitivity to trade policy changes and the significant impact judicial decisions can have on investment flows. Investors appear to be betting on stronger economic growth in emerging markets now that tariff uncertainty has been lifted, potentially setting the stage for broader emerging-market outperformance in the coming quarters.
