From Seoul's Neon Glow to New York's Volatility Vortex: A Trans-Pacific Trading FrenzyImagine a late-night ritual in Seoul: Thousands of young professionals, bleary-eyed and buzzing with adrenaline, swipe through mobile apps under the hum of K-pop playlists and instant ramen steam. It's not gaming or binge-watching—it's trading. But not on the tame Kospi exchange. No, these are South Korea's retail investors, channeling their inner Squid Game contestants, betting big on the wildest corners of Wall Street. Their weapon? Unbridled risk appetite, leveraged bets, and a herd mentality that's already pumped nearly $170 billion into US stocks by October's end—a near-doubling from the year's start. What began as a domestic quirk—retail traders driving over half of Korea's daily volume—has gone global, injecting meme-stock mania into America's blue-chip facade. Wall Street, meet your new disruptors.
