  "summary": "The Korea Exchange (KRX) introduced after-hours trading on Monday, operating between 4 p.m. and 8 p.m., aiming to enhance global competitiveness and provide more trading opportunities for investors. During the inaugural four-hour session, a significant 72.24 million shares worth 1.8 trillion won were traded, a stark contrast to the 905 million shares valued at 25.8 trillion won that were exchanged during the regular trading session. Notably, the frequency of volatility interruption mechanisms surged to 1,637 times, more than three times the 400 activations observed during the regular trading. This increase in volatility was largely attributed to insufficient liquidity, coupled with the allowance of real-time buying and selling of a broad spectrum of stocks. However, investors were prohibited from trading exchange-traded funds and exchange-traded notes during this period due to concerns about potential market volatility.",
