Hello, SKL3S is a 3X short ETF product for SKL. Its price fluctuation is about three times that of the SKL market. However, due to the existence of regular and ad hoc adjustments, the price fluctuation over a certain period of time is not always three times. The ETF product hedges through the Perptual Futures market. Profit will enter a position, and loss will reduce position. The leverage ratio will be adjusted back to 3x daily. Due to the adjustment mechanism and holdings cost, leveraged ETFs are not suitable for long-term holding. ETF products have large price fluctuations and high risks. Please participate with caution. For detailed rules, please see the leveraged ETF document in the problem center.
