CBOE 的 DUG Option chains 数据 - 求教一个弱智问题

又忘了密码

如图，今天从CBOE看到的DUG 的option 价格，在strike 30 处call 的价格和put的价格怎么相差那么大？是数据错误么？还是价格不是同一时间的？先谢了

DUGED has no trade for a while, the quote you saw was old. also there are two series DUGXX adn DZGXX [ 本帖最后由 jsl 于 2008-4-18 20:14 编辑 ]

我猜一下。 这些option表明大家觉得dug价格应该在33左右（max pain？）。不是当前的30

Thank you. I just found from optionsxpress DZGXX. BTW, from CBOE, I can only find DUGXX, where can I find DZGXX from the exchange?

Thanks. As jsl said, these data are out of date, possibly when the price of the underlying was around 34.XX.
