你买卖Call或Put的时候，或看报价的时候有个日期......在欧洲市场Option在该日到期，Option只能在当日交易（或放弃），而在美国市场这个到期日是某个月份，即到该月最后一个星期五到期，但Option则可以在此前的任何一个交易日交易，过了该日则算放弃。

$35+$2.5表示约定远期股票价格$35，Option合约交易价格为$2.5/股。应该还应注明是Put还是Call

是一股$2.5还是100股?要是一股$2.5也太贵了.从一网上看1 contract 是100股.是不是说我想put or short还不一定有. thanks

当然是一股$2.5，就拿链接里的例子，10 MSFT JUN 55 CALL，每股$2.5，1000股（10手）就是$2500嘛。

100股的option是$250. 无论你要买/卖put/call, option exchange都会买/卖给你

谢谢,明白了点，但是my broker不允许在持有同种股票时put or call，另外是不是cover 还有一次commission? option价格是固定的吗? who decide that?

Option在买入（卖出）时有Commission，比股票略高些。在Exercise时还有一个Commission。但这些比起收益（亏损）而言，几乎可以忽略不及。Option的价格应该是可变的，但变化很小。

Option的价格变化是很大的，方向错了，可以成废纸。

变化大的是股票的价格，而Option的价格只有其几分之一，甚至几十分之一。Option的作用就是四两拨千斤，当然，拨错了方向，砸到脚也是很要命的。

Option的价格一天变化40-50%是常事，翻一翻砍一半也正常。

to jeffrey815: apparently the 'seasoned equity' means common stock of company that is already trading in the open market. it is a term used to differenciate from IPO.generally corporate bond issuers pay up to 2% to the underwriters. i don;t know how much for stocks but it seems to be higher.
