利率市场趋势定量跟踪：利率择时信号维持中性偏空

• The report introduces a multi-cycle timing strategy for interest rates, which is constructed using shape recognition algorithms to identify support and resistance lines in interest rate trends. The strategy combines signals from short, medium, and long cycles to form composite timing views. The switching frequency for these cycles is weekly, bi-weekly, and monthly, respectively[10][23][24] - The multi-cycle timing strategy is based on the principle that when at least two cycles show downward breakthroughs of support lines and the interest rate trend is not upward, the portfolio is fully allocated to long-duration bonds. Conversely, when at least two cycles show upward breakthroughs of resistance lines and the interest rate trend is not downward, the portfolio is fully allocated to short-duration bonds. Other configurations include mixed allocations depending on the direction of the interest rate trend[23] - The strategy employs a stop-loss mechanism where the portfolio is adjusted to equal-weighted allocation if the daily excess return falls below -0.5%[23] - The backtesting results of the multi-cycle timing strategy show a long-term annualized return of 6.17% since 2007, with a maximum drawdown of 1.52% and a return-to-drawdown ratio of 2.26. Short-term results since the end of 2023 indicate an annualized return of 7.24%, a maximum drawdown of 1.55%, and a return-to-drawdown ratio of 6.21[23][24] - The strategy has consistently outperformed its benchmark, which is an equal-weighted duration strategy, with a long-term excess return of 1.65% and a short-term excess return of 2.14% since the end of 2023. The excess return-to-drawdown ratio is 1.17 for the long term and 2.29 for the short term[23][24] - Historical performance analysis reveals that the strategy achieved a 100% success rate in generating positive absolute returns and excess returns annually over the past 18 years[24] - The report also tracks the behavior of public bond funds using an improved regression model to estimate the duration and divergence of medium- to long-term pure bond funds. The latest results show that the median duration of public bond funds, including leverage, is 3.51 years, with a 4-week moving average of 3.45 years. This represents an increase of 0.13 years and 0.04 years compared to the previous week, respectively, and places the duration level at the 96.53% percentile over the past five years[6][13][14] - The divergence in public bond fund duration, measured by the cross-sectional standard deviation, is 1.55 years, which is slightly lower than the previous week and is at the 59.07% percentile over the past five years[6][14] - The yield-to-maturity (YTM) data for public bond funds, calculated similarly, shows a median YTM of 1.7%, a 4-week moving average of 1.74%, and an average of 1.79%. Compared to the previous week, the unsmoothed median YTM decreased by 4 basis points, while the smoothed data decreased by 3 basis points, indicating that institutional holdings are near historical lows[18]
