$SPDR S&P 500 ETF Trust(SPY)$ Asian investors account for roughly 75% to 80% of all overnight U.S. trading volume. Since the U.S. overnight session (8:00 PM to 4:00 AM ET) aligns with daytime business hours in Asia, regional retail investors use this window to trade U.S. equities without staying up all night.

- South Korea: Contributes the single largest share, making up about 40% to 65% of the platform's entire overnight volume depending on regional retail momentum.
- Other Asia-Pacific Markets: Account for another roughly 30%, driven heavily by active traders in Japan, Hong Kong, and Singapore.
- United States & Rest of World: Comprise the remaining 20% to 25%, which mostly consists of domestic U.S. retail investors trading meme stocks or reacting to late-night corporate earnings reports.
