????我們曾就期權買賣如何影響蘋果(Apple)股價寫過很多文章。因此，我們覺得如果看看有一天蘋果股價反過來推動期權市場——所謂的Max Pain價格，即期權賣家利潤最大、買家損失最大的執行價——的情況，一定很有啟發意義。

????自從去年7月蘋果的一周期權開始交易以來，幾乎每個周五蘋果股價都收于或接近Max Pain價格，如果上周五沒有中國iPad 工廠爆炸這樣的意外消息影響，可能也會這樣。

????上面兩張圖源自讀者密克?布萊基的一張幻燈片演示稿。在現實生活身為火箭科學家兼資深電腦用戶的布萊基一直密切跟蹤Max Pain價格的變動。圖一是上周五開盤前的截屏，Max Pain價格為340美元。蘋果股票開盤報339.56美元，日間交易區間不超過1美元，直到中國工廠爆炸消息傳出。圖二是收盤后的截屏，Max Pain價格已降至335美元。蘋果股價收于335.22美元。

????We've written a lot lately about how traders buying and selling options seem to be driving Apple's (AAPL) share price (see here, here and here.) So we thought it might be instructive to look at what happened on a day when Apple's share price took over and drove the options market -- specifically, the so-called Max Pain price point where options writers make the most profit and options buyers suffer the biggest losses.

????Apple's shares have closed at or near Max Pain nearly every Friday since weekly option trading in Apple began last July, and they might have done so again last Friday if unexpected news -- in the form of an explosion in a Chinese iPad factory -- hadn't intervened.

????The charts above are from a slide show put together by reader Mick Blackledge, a real-life rocket scientist and veteran computer user who's been following the Max Pain story closely. In the first chart, a snapshot taken before Friday's opening, Max Pain stood at $340. Apple opened at $339.56 and traded within a $1 range until news of the explosion in China crossed the wires. In the second, taken after the closing bell, Max Pain has shifted to $335. Apple closed at $335.22.
