Core Viewpoint - The article discusses two common hedging strategies: protective put strategy and collar strategy, highlighting their effectiveness in different market conditions, particularly during market downturns [1][2]. Group 1: Protective Put Strategy - The protective put strategy significantly reduces maximum drawdown during the downtrend of the 300ETF, decreasing it from 42% to 27% [2]. - In downtrending phases, in-the-money put options outperform a pure hold strategy on the ETF, while out-of-the-money options show weaker performance except during sharp declines [2]. - The strategy is more effective in covering option costs during prolonged downturns due to frequent triggers of in-the-money options, while out-of-the-money options incur larger cumulative losses [2]. Group 2: Collar Strategy - The collar strategy does not outperform the 300ETF overall, with annualized returns around -1%, compared to the ETF's 2% [3]. - However, the collar strategy reduces maximum drawdown to below 30%, compared to the ETF's 42% [3]. - In down markets, the collar strategy benefits from using in-the-money puts for strong protection and selling high-strike calls for additional income, creating a dual enhancement effect [3]. - Caution is advised when using the collar strategy during uptrending markets due to potential losses from exercised calls and untriggered puts [3]. Group 3: Performance of Structured Hedging Products - Structured hedging strategies like TAIL and JHEQX have shown effective drawdown control during market volatility, with JHEQX demonstrating a more moderate decline compared to the S&P 500 during the significant market correction in 2022 [1]. - The barbell strategy employed by TAIL combines bonds and options to provide a hedge during market panic phases [1].
