[討論] 如果真的有聖盃,那應該是藏在做空的奧義
今天在工作上有感而發,不知道習慣自己東拼西湊各種程式交易演算法
的各位同好,你們是否有一種體認,就是做多能賺的策略遠遠多於做空的
策略,且績效也相對好很多.我可以跟各位保證,你們可以很容易的用一般
的均線或技術指標,開發一個只做多,不做空(空頭時出場觀望)的賺錢系
統,但是你大概很難發明一個只做空,績效一樣好的系統.原因倒不全是
因為股市長期以來以多頭格局居多,我認為關鑑在於"指數"大都急跌,多
頭波段,股票可以慢慢買,指數也不會一下就到高點.偏偏做空時,大都只能
做指數期貨的放空,融卷放空,對資金的容納度有限,且很多市場法規也讓
放空股票變的不容易. 要靠放空指數賺錢,必需很精準的抓住頭部,且很快
速的在下跌滿足點出場.否則很容易白忙一場又被嘎掉獲利.小弟在此開個
端,希望大家踴躍發表高見.洩洩~
