Stock markets across Japan, South Korea, and Taiwan experienced significant volatility last month, driven largely by gains linked to artificial intelligence and increased investor leverage, according to KrASIA.

Japan’s benchmark Nikkei Stock Average reached a record high of 72,366.34 points on June 25 before dropping 4% to 69,360.88 points the following day. Over the past year, the Nikkei has surged nearly 80%, highlighting the strong influence of AI-related sectors on market performance.

For Japanese investors, this volatility underscores the growing impact of technology trends on equities, emphasizing the need for careful risk management amid rapid market shifts.
