高斯量化1号净值比较.xlsx

果仁“我的组合”中最底部3个最优策略。1和3组合的相关系数矩阵都较小,可以叠加美林和国债期货策略。 1 3 最优2本质上是个大小混合而已,象去年那样的极端行情,也能赚钱,只要不单一押大小就可以(可惜我们去年就是在押) 2

对比我们目前的部分子策略的相关系数矩阵(好几个策略都是偏向大盘蓝筹的,是我们主观增加曝光的),上面的矩阵基本没有超过0.4的全都是绿色的 cu

3个组合策略的收益曲线,3最好 11 22

最大回撤也是3最好

33

要讨论的问题就是:那么我们要不要改。这个变动会比较大,需要大家考虑下讨论下。

我的出发点是:1. 想理清策略挑选的逻辑,比如相关系数小那也是个标准化的逻辑,目前权重和策略挑选上都有人为因素。2. 目前策略有不少策略间相关性较大,属于主动曝光某个方向,而例如最优3这样的相关系数最小的策略更为被动。在我们方向曝光错误的情况下就会出现一些差别,例如我们1个月的收益只有1%,同期最优123组合的收益为1.5%,2.8%,3.5%。3. 操作层面上,现在有多达接近20个策略,是否能有此进行下简化

上面最优3组合只是样本,还有优化空间,比如,子策略次新和最小市值进一步进行大小轮动后表现会更好。同时我还认为剔出了一些不合时宜的策略,例如ST摘帽,最近跌跌不休,以前持续有效,相关性虽然小,但考虑到目前环境没有选进去。

“KCC has made numerous attempts to engage in constructive negotiations with Gecamines regarding the recapitalisation plan,” Katanga said in a statement. “However, Gecamines has, instead of meaningfully engaging with the company, unilaterally commenced the proceeding.”
