Group 1: Market Volatility - The recent market fluctuations have been more significant compared to previous years, with the A-share market performing relatively well, while the US stock market has experienced a notable decline of over 20% in the last two months [4][6]. - Long-term investors may view recent downturns as mere corrections, but those who entered the market in January may feel the impact of a 2.6%+ decline over a month [6]. Group 2: Key Metrics for Safe-Haven Assets - Important metrics for evaluating safe-haven assets include maximum drawdown, recovery time from drawdowns, and the probability of positive returns over various holding periods [11][12][13]. - The analysis includes various global stock markets, bond markets, commodities, and cash-like investments to determine their performance as safe-haven assets [14][15].
