期貨跟OP來到價內後,風險是一樣的,
至於損失會不會無限,不會,只是都可能會破產。
那麼期貨跟OP賣方誰比較容易破產?
一定是OP,那就怪了,期貨跟價內OP虧的錢一樣阿,
不一樣,因為實務上OP的賣方就是會壓得比期貨大。
比方說,小台我留倉10口,OP則可能賣出50口。
如果OP我也只賣十口,那不太可能。
這還是保守的說法,有些是押到千口。
那麼430的時候,這種裸賣根本無法處理。穿過去就是
破產了,沒什麼好講得。
OP的裸賣要不就小小賣幾口,怡情養性,要拿來賺身家,
裸賣只是在等黑天鵝而已。算是找死的行為。
至於有人說,我可以做價差交易阿,那就對啦,不要裸賣。
※ 引述《circlelee (悟x)》之銘言:
: 1 賣方每次爽爽贏,輸一次就賠光
: 這句話,完完全全是嚴重誤解賣方
: 也嚴重不了解指數的波動程度。
: 事實上 做op賣方比玩台指期(大小台)賠的還少
: 損失無限? 真的是扯翻天的謬誤迷信
: 2 賣方不能讓履約價被穿價,否則賠翻
: 也不太對。
: 3 遠價雙賣是最安全的賣方方法
: 也不太對。它算勝率高,但不是最高。
: 它算賠的少,但也不是最少。
: 以期望值來看,它並非是最理想的。
: 而甚至可能是績效很差的一種方式。
: 我不解釋太多 我喜歡激起回應
: 說不定是我錯,但這機率極低。
: 請各位op高手指教了
