(這是第一次在op版po文>_<"")
我的想法和阿漢大不太一樣@@”
基本上如果要做多期貨+太價外的Buy Put來避險我覺得是不必了(除非是大戶)
但是對於下面這種情況就適合這樣做:
想要波段獲利卻沒定性的非高手-.- 。
舉例在6000點的時候做多一口期貨,你預定要賺到1000點的波段利潤
但是行情總是不太可能一路漲了1000點,於是你預期在某一天會大跌
這時候就可以用價平或價外(內)1~2檔左右的Buy Put來進行操作。
這樣的好處是,假設行情不如你預測時(隔天續漲),你的波段單不會動到(這是重點!)
,而Buy Put可以選擇加碼攤平(預期隔沒幾天會跌),或是損失平倉。
如果行情如你預測,當然波段單也是不會動到,但是這時就可以把Put的部位獲利了結。
所以你的最終獲利除了原先的波段單1000點的利潤(沒動到的情況)+Buy Put的損益
或許有些聰明的大大想到了,既然預期會下跌,那期貨先空手或反手做空不就好了?
簡單的分析一下情況給大大們聽:
(A) 預期正確
1. 波段單不動>>獲利不變。
2. 波段單空手等下跌低接>>1000點+下跌的部分。
3. 波段單反手做空又買回來>>1000點+下跌的部分X2。
(B) 預期錯誤
1. 波段單不動>>獲利不變。
2. 波段單空手等下跌低接>>1000點-下跌的部分。
3. 波段單反手做空又買回來>>1000點-下跌的部分X2。
但是kiwi小小想說:這畢竟是高手大大才能這樣玩阿~~
我覺得對於要做波段的人來說,經常還會去想動自己的部位,那這樣就不算是波段單了。
況且行情總是不如預期,如果真的那麼準做當沖就好了幹麻做波段,對吧?
或許有人覺得A和B二個看起來差不多,其實我也覺得差不多
最近想到一個很簡單的道理,但是大家卻又會容易忽略的思維。
一筆錢: 10萬 >> 5萬 >> 10萬。
看出差別了嗎?
或許用看的感覺差不多,但是當你用賠的時候只損失50%,
要賺回來同樣的錢卻需要100%。
所以A和B還會差不多嗎,事實上一來一回差蠻多的。
說了那麼多,只是想表達 做多期貨+Buy Put也是有好用的地方。
-------------------------------------------------------------
對於期貨+BP 和 期貨減碼這二種操作方式,我就在仔細說明一下差異好了
首先波段獲利這個前提要是成立的 (看對大方向趨勢)
以5口期貨單假設每口最終能獲利200點
在獲利100點的時候預期會下跌:
(1)5口期貨單調節出2口
判斷正確時(下跌): 獲利點數 = 3口x200 + 2口x(100+[?])
判斷錯誤時(上漲):獲利點數 = 3口x200 + 2口x(100-[?])
其中[?]表示還需要進行下一個進場點判斷
因為出了2口單之後可能買回或不買回
(2)5口期貨單+BP
判斷正確時(下跌): 獲利點數 = 5口x200 + BP
判斷錯誤時(上漲):獲利點數 = 5口x200 -BP
若是能將風險控管在 BP能得到的獲利= (1)判斷錯誤時少賺的獲利
那是不是相較之下較(1)就單純的多了?
