假設目前有3支策略在RUN
3支都是順勢,correlation相互介於0.7-0.8之間
以年為單位比對,用MC Portfolio測的
由於相關性太近,所以策略組合能降低的drawdown有限,
且創造力低落也寫不出其他邏輯的順勢策略來了
現在有一想法,寫一支逆勢策略,回測績效為
逆勢 profit factor = 1.4 3支順勢平均 profit factor = 2
net profit/MDD = 3.0 net profit/MDD = 5
逆勢的績效超爛,沒辦法我程度低落...
不過對上其他順勢correlation都只有0到負0.2之間
我在想其實只要策略組合的net profit/MDD有上升,達到互補作用
單一策略績效很爛也都是可以考慮的吧? 不知道各位有什麼想法
