What's happening
Goldman Sachs released striking data this week: the South Korea ETFExchange-Traded Fund - a basket of securities trading like a single stock. (EWY) now represents approximately 14% of all global equity ETF volume based on a sample of 688 funds. This is not a measure of assets under management but of daily trading activity, meaning the ETF has become a lightning rod for momentumThe empirical fact that winners keep winning over the medium term. flows. The level of concentration reflects a powerful structural bet on Korean tech (Samsung, SK Hynix) and manufacturing exposure amid AI infrastructure buildout.
The rally in South Korean equities has been driven by several forces: a favourable currency tailwind from yen weakness (Japan's intervention to defend the yen after Golden Week volatility), global appetite for semiconductor and memory-chip exposure, and a perception that Korean companies offer better valuations than US tech peers. However, the massive concentration of ETFExchange-Traded Fund - a basket of securities trading like a single stock. trading volume in a single geographic wrapper creates tail risk. If momentumThe empirical fact that winners keep winning over the medium term. traders reverse positions, the liquidity that has driven the rally could evaporate just as quickly.
Goldman Sachs' own data publication on this phenomenon suggests the bank sees it as noteworthy enough to call out, implying potential concern about crowding. Broader macro headwinds like Trump-Xi tensions, further yen intervention needs (which could reverse if geopolitical tensions ease), or a slowdown in Samsung's AI chip orders from Chinese customers could all trigger a sharp reversal.
The paradox is that this very crowdedness may also be why the trade has legs; momentumThe empirical fact that winners keep winning over the medium term. strategies are locked into ETFExchange-Traded Fund - a basket of securities trading like a single stock. flows, and retail positioning via ETFs means any unwinding takes time. But for traders sensitive to crowded-trade risk, EWY is a name to watch for signs of distribution or early warning signs of rotation.
