大股東站在買方的績優成長股

大股東站在買方且近期漲幅不大，然後基本面連2季毛利率成長，過去五年到少有1年獲利大於3元，再搭配近一日外資買超佔成交量一成以上，這樣基本面+技術面+籌碼面的組合，往往可以找到短線呈現多頭走勢的股票

以下的策略，是根據這個想法，所設計出來的

其中大股東站在買方的腳本如下

複製
1value1=GetField("關鍵券商買賣超張數","D");
2value2=getField("關聯券商買賣超張數", "D");
3value3=getField("地緣券商買賣超張數", "D");
4if GetField("內部人持股比例","M")
5>GetField("內部人持股比例","M")[1]
6or GetField("大戶持股比例","W",param := 1000)
7>GetField("大戶持股比例","W",param := 1000)[1]+0.5
8or value1>=500
9or value2>500
10or value3>500
11then ret=1;
12outputfield(1,GetField("內部人持股比例","M"),0,"內部人");
13outputfield(2,GetField("內部人持股比例","M")[1],0,"前期內部人");
14outputfield(3,value1,0,"關鍵券商");
15outputfield(4,GetField("大戶持股比例","W",param := 1000),1,"千張大戶比例");
16outputfield(5,GetField("大戶持股比例","W",param := 1000)[1],1,"前期千張大戶比例");
value1=GetField("關鍵券商買賣超張數","D");
value2=getField("關聯券商買賣超張數", "D");
value3=getField("地緣券商買賣超張數", "D");
if GetField("內部人持股比例","M")
>GetField("內部人持股比例","M")[1]
or GetField("大戶持股比例","W",param := 1000)
>GetField("大戶持股比例","W",param := 1000)[1]+0.5
or value1>=500
or value2>500
or value3>500
then ret=1;
outputfield(1,GetField("內部人持股比例","M"),0,"內部人");
outputfield(2,GetField("內部人持股比例","M")[1],0,"前期內部人");
outputfield(3,value1,0,"關鍵券商");
outputfield(4,GetField("大戶持股比例","W",param := 1000),1,"千張大戶比例");
outputfield(5,GetField("大戶持股比例","W",param := 1000)[1],1,"前期千張大戶比例");

這個策略過去七年，停損停利都設為7%，回測報告如下圖

這樣的策略在景氣行情中表現不錯，在無基之彈中表現就會比較差
