Group 2 - The current market rally shares characteristics with previous policy-driven surges, such as the "5·19 rally" in 1999 and similar events in late 2008, late 2014, and early 2019, suggesting a potential for a subsequent consolidation phase after the initial surge [2]. - Following the rally, the market experienced profit-taking on October 9, with a decrease in trading volume and increased divergence between bulls and bears, indicating a shift towards a consolidation phase [2]. - For investors holding index or ETF positions, employing a collar strategy is recommended to manage downside risk during this volatile period [2]. Group 3 - The collar strategy involves holding the underlying asset, buying put options for downside protection, and selling call options to offset the cost of the puts, making it suitable for investors with a bullish long-term outlook [3]. - When selecting put options for the collar strategy, shallow out-of-the-money puts are preferred for minor declines, while deep out-of-the-money puts are chosen for potential significant downturns, allowing for greater coverage against losses [3]. - The choice of call options in the collar strategy should consider the potential upside, typically opting for higher out-of-the-money options to limit profit caps while managing risk [3]. Group 4 - An example of the collar strategy using the Shanghai 50 ETF illustrates its effectiveness; an investor bought a shallow out-of-the-money put option and sold a high strike call option, resulting in a return of 1.34% with a maximum drawdown of 0.44%, compared to a -3.16% return and 8.93% drawdown for the underlying ETF [4][5]. - The collar strategy demonstrated superior performance in terms of risk management and return compared to simply holding the underlying asset, especially in a volatile market environment [5].
