Tesla's share price has experienced a substantial decline, dropping approximately 40% recently, which has adversely affected investors in South Korea who engaged in leveraged trading of the company's stock. Reports indicate that some shareholders have received margin calls from securities firms due to this downturn. The situation has led to a significant drop in the value of Tesla-related leveraged exchange-traded funds (ETFs), with one 3X long ETN plummeting 85% from its peak in December. South Korean investors reportedly hold over 90% of these leveraged ETFs, which have been described as risky bets on the U.S. automaker's performance. The decline follows a remarkable 575% surge in the stock price post the 2024 election, highlighting the volatility and risk associated with such investments.
