firstrade把我的put not exercised - 理財

※ 引述《scoy (Fire)》之銘言：
: Firstrade這幾天把我12月到期價內的選擇權assign 成not exercised
: 原因是因為我沒有持有該標的現股沒得賣
: 我是覺得挺怪的，因為既然是價內broker 為何不幫我買股來賣
: 我查了google
: https://www.google.com.tw/amp/s/investorplace.com/2010/09/options-expiration-and-in-the-money-puts/amp/
: 這頁面也說“If you don’t have the shares in your account (and most people
: don’t), your broker will buy them on your behalf and then sell them.”
: 向Firstrade 反應了也沒用 他還是堅持你要持有現股才能exercise
: 我覺得這是一個在邊際的問題
: 可以說他的做法合理也不合理
: 不知道其他券商都是怎麼做的
: 大家有何想法或經驗可以回饋給我
以傳統的週五到期option來說，當決定是否價內的時候，股票市場已經收盤了
硬要從盤後交易買股來賣...光是BID/ASK spread可能就倒虧好幾倍
另一個選擇則是借券來賣

然而，借券來賣，首先是不一定有券可以借
帳號的權限與額度也不見得能允許借好借滿
再者，可能會在回補部位時受到損失

是否允許借券來執行價內put
不同券商可以有不同的政策
如果券商不同意這麼做，你只好換家券商了

You got to know when to hold 'em, know when to fold 'em, Know when to walk away and know when to run.
You never count your money when you're sittin' at the table. There'll be time enough for countin' when the dealin's done.

'Cause ev'ry hand's a winner and ev'ry hand's a loser, And the best that you can hope for is to die in your sleep."
now Ev'ry gambler knows that the secret to survivin' Is knowin' what to throw away and knowing what to keep.
