全球市场ETF轮动策略 - 本地回测版本
|
||
原始策略来源：聚宽 https://www.joinquant.com/post/1399
|
||
|
||
核心逻辑（与动量策略共用）：
|
||
1. 加权线性回归（权重1→2递增）计算趋势得分
|
||
2. score = 年化收益率 × R²
|
||
3. ATR动态调整回看窗口（20~60天）
|
||
4. 崩盘过滤：连续3天任一天跌>5%则得分归零
|
||
5. 溢价过滤：溢价率≥5%则降权
|
||
6. 全仓单一品种轮动
|
||
|
||
ETF池：全球化配置
|
||
纳指100 / 日经225 / 德国DAX / 黄金 / 有色金属 /
|
||
南方原油 / 30年国债 / 红利低波 / 创业板
