在網路看到別人提出這個策略,想說那就來回測看看,看起來是有回測價值
於是開始做參數調整,那這邊要考慮的點第一個是週期,以天為單位做交易週期對我來說太困難(資金量不夠),其實以週為單位仍然需要蠻大筆資金,但以月為單位太不現實,所以基本上就是以週為週期做交易。
第二個問題是殖利率的問題,去XQ查發現定義如下:(現金股利 + 股票股利) ∕ 收盤價 * 100%。然後是以前一年為單位,而不是平均5年之類。
那可以看到,在殖利率6%表現是最好的,策略回測到這邊基本上就可以用了,但我本人後續是想做現金殖利率部分回測看看,就等之後有做再把內容補上來。

改成現金殖利率之後
4%:73.28%/438.05%
5%:74.86%/497.27%
6%:77.63%/553.21%
7%:77.03%/522.12%
8%:75.09%/450.83%
基本上,勝率跟報酬率都提高,虧損方面無顯著差別,然後還是6%回測起來表現最好。
然後是再更改淨值比
淨值比1.5倍情況下
4%:75.58%/478.82%
5%:77.46%/516.08%
6%:79.21%/599.53%
7%:78.74%/648.61%
8%:75.89%/450.70%
淨值比1倍情況下
4%:78.13%/562.18%
5%:77.83%/617.68%
6%:80.74%/711.42%
7%:70.54%/767.00%
8%:80.33%/303.95%
股淨比維持2倍,本益比改10倍或12倍的情況下,績效都沒有比原本好。
其他不變,持有時間更改的話(淨值比1.5倍)
13週:64.79%/936.22%/-52.66%
14週:66.77%/1068.71%/-52.97%
22週:71.51%/873.41%/-53.59%
26週:73.18%/801.02%/-48.99%
39週:76.53%/739.80%/-57.44%
52週:79.21%/599.53%/-65.15%
以報酬率來說的話,持有14週(一季),報酬率最高,但勝率不到7成,考量到實際情況的話,以上面選股條件,至少持有兩季,我覺得是比較合理的情況。

39週:83.56%/1769.81%/-29.79%

目前
成交量3-3.5倍
持有時間26週
淨值比以1.5倍
現金殖利率6%
但後續還必須回去看交易次數,次數太少的話可能也不適用。

PE13 / PB1.4 會更好
技術面60/120最好
月營收YOY>0%最好
稅後淨利1季成長就好最好
