吼~~~ 我少說也算操作 期貨 選擇權也算好歹超過一段時間
有時候看盤整的時候 我也會做一下 賣方勒式
就像我從上星期 賣6500 PUT ~~7500CALL 部位
有個小問題一直覺得很疑惑 = =
書上都嘛說 [波動率大的時候 比較適合當選擇權賣方]....(  ̄ c ̄)y▂ξ
可是就覺得怪怪 通常賣方要賺的不就是結算前 開始縮水的"時間價值"嗎??
我怎麼覺得結算前盤整 指數沒啥波動的時候 反而比較能穩穩的賺取慢慢消逝"時間價值"?
可是偏偏書上又說 波動率大 -->賣方?!
(因為有時候我會發現 當大盤當天指數有大波動的時候
原本有賺到的時間價值 反而因為call or put 大漲 而縮水 = =|||
今天也是咩~~ 上攻到季線 我發現今天所賺的時間價值獲利 居然跟昨天差不多
也就是我今天選擇權賣方的部位 跟昨天比起來 時間價值根本沒流失 = =)
咦咦咦?? 好怪 = = 這樣不是跟書上講的波動大的時候適合當賣方不一樣嗎??
不是很多選擇權賣方因為一個大跳空 大波動就掰了掰???
還是書上的意思只是指 "波動大的時候 適合當賣方進場 比較能賣到好價錢的權利金?"
(至於賺取"時間價值"啥的就不一定?? 雖然我知道最近波動率好像比較大
選擇權易漲難跌 所以好像比較難賺到時間價值??)
究~~~竟是我有哪個觀念 還是哪個地方沒注意而搞錯嗎?? @@
在此問個笨問題 向版上高手們請教一下 謝謝 ( ′-`)y-~
