Core Viewpoint - The article discusses the significant discount in the futures market compared to previous years and the higher implied volatility of put options compared to call options, suggesting a potential pessimistic outlook among investors. It proposes a quantitative timing strategy based on the synthetic underlying price of ETF options to address these issues [1]. Group 1: Concepts of Premium and Discount - The premium and discount of stock index futures is defined as the difference between futures prices and spot prices, with a positive value indicating a premium and a negative value indicating a discount. The annualized premium rate is often used for better comparison [2]. - The seasonal discount phenomenon in stock index futures is attributed to dividend payouts from constituent stocks, which can lead to a natural decline in the index and is particularly evident from May to September [2]. Group 2: Synthetic Underlying of ETF Options - The price of the synthetic underlying for ETF options can be expressed using the call option price, strike price, and put option price. The premium or discount rate is calculated as the difference between the synthetic price and the underlying ETF price [3]. - There is a strong positive correlation (over 0.97) between the annualized premium rate of the synthetic underlying of ETF options and the annualized premium rate of stock index futures after excluding dividends, indicating that the synthetic underlying may provide a more accurate reflection of market expectations [3]. Group 3: Quantitative Timing Strategy Backtest Results - The strategy suggests that when the valuation of put options is significantly higher than that of call options, it does not necessarily indicate a market downturn. Instead, it may present a buying opportunity [4]. - The strategy is based on the premise that when the ETF synthetic underlying futures premium is at a historical low, it indicates excessive pessimism, and a potential rebound may occur, prompting a buy signal for the next trading day [4]. Group 4: Historical Backtest Performance - The strategy has shown significant outperformance compared to the underlying ETFs since 2018, with an annualized return of 19.05% and a maximum drawdown of -17.83% when trading the Huatai-PineBridge 300 ETF [6]. - The cumulative return of the timing strategy reached 142.9%, significantly higher than the 51.8% return of the IC monthly contract and 2.52% of the 500 ETF [6]. Group 5: Summary - The article highlights the relationship between the synthetic underlying of ETF options and stock index futures, emphasizing the effectiveness of a quantitative timing strategy based on the synthetic premium. The results indicate that significant discounts in the futures market do not necessarily signal a sell-off but rather present opportunities for long positions [12].
