英文摘要:
We propose a new heavy-tailed distribution --- Gaussian-Chain (GC) distribution, which is inspirited by the hierarchical structures prevailing in social organizations. We determine the mean, variance and kurtosis of the Gaussian-Chain distribution to show its heavy-tailed property, and compute the tail distribution table to give specific numbers showing how heavy is the heavy-tails. To filter out the heavy-tailed noise, we construct two filters --- 2nd and 3rd-order GC filters --- based on the maximum likelihood principle. Simulation results show that the GC filters perform much better than the benchmark least-squares algorithm when the noise is heavy-tail distributed. Using the GC filters, we propose a trading strategy, named Ride-the-Mood, to follow the mood of the market by detecting the actions of the big buyers and the big sellers in the market based on the noisy, heavy-tailed price data. Application of the Ride-the-Mood strategy to five blue-chip Hong Kong stocks over the recent two-year period from April 2, 2012 to March 31, 2014 shows that their returns are higher than the returns of the benchmark Buy-and-Hold strategy and the Hang Seng Index Fund.

中文摘要:
我们提出了一种新的重尾分布——高斯链分布,这是受社会组织中普遍存在的等级结构启发而产生的。我们确定高斯链分布的均值、方差和峰度以显示其重尾特性,并计算尾部分布表以给出显示重尾有多重的具体数字。为了滤除重尾噪声,我们基于最大似然原理构造了两个滤波器——二阶和三阶GC滤波器。仿真结果表明,当噪声为重尾分布时,GC滤波器的性能远优于基准最小二乘算法。利用GC过滤器,我们提出了一种交易策略,名为“骑行情绪”,通过检测市场中大买家和大卖家的行为来跟踪市场情绪,该策略基于嘈杂、重尾的价格数据。在2012年4月2日至2014年3月31日的两年内,将“搭便车”策略应用于五只香港蓝筹股,结果表明,它们的回报率高于基准买入持有策略和恒生指数基金的回报率。
