I'm here wondering if the Korean whales will still come into action, because the South Korean stock market, known as KRX (Korea Exchange), usually operates at specific times. Trading hours, which is when investors can trade stocks, start at 9 AM and go until 3 PM, local time in South Korea (KST).
Currently, South Korea is 12 hours ahead of Brazil (Brasília time), so when it is 9:46 PM here in Brazil, it is already 9:46 AM the next day in South Korea. Therefore, the South Korean market is already open and investors can start trading.
