※ 引述《centaurjr (魔術師)》之銘言:
: 卡恩斯週四深夜在看了他的羅賓漢賬戶後顯然陷入了絕望,賬戶裡似乎有1.6萬美元,但
: 現金餘額也顯示為負730,165美元。在福布斯看到的最後一份筆記中,卡恩斯堅稱,他從
: 未授權過保證金交易,並震驚地發現,他的小賬戶竟然會出現如此明顯的虧損。
光這句話就有問題惹
很明顯的他做期權是裸賣,不然根本不可能會有負餘額出現
然後裸賣一定要融資帳戶(保證金帳戶)才能開權限
白話來說
這小子拿1.6萬美元去玩一個73萬美元的交易喇
整個過程大概是這樣
某股票現在50鎂
下個月到期的49和50元的put分別是0.5跟1元
如果我買入49元put和賣出50元put各一張合約
那麼我能先拿到(1-0.5)*100=50元現金(一張合約=100股)
但是我有義務在股票低於50元的時候以50元買入
也就是我手上的購買力要有50*100=5000美元
雖然說我能在結算時用49元賣出
啊問題是
你原本手上沒股票是要賣個屁
就算是買來賣也要你有錢可以先去買股票R
更不用說這種作法其實就是開槓桿
開槓桿哪有在放到結算的喇
不就是手上沒那麼多錢才要開槓桿嗎
結果放到結算你還是要花一堆錢去行權
那開屁槓桿= =
再來,我沒記錯的話期權交割是T+1但股票是T+2
你的buy put會比股票早交割
所以實際上你還是要花錢吃下這堆股票才行
結論
這人就是韭菜,不懂交易還敢玩OP啊
然後券商也有問題,為啥能給一個沒經驗又沒收入的學生開裸賣權限
家屬拿這個去吵搞不好真的能吵到什麼結果
