"We, however, also saw some parallel option trading activity in another name in the space, Bucyrus , which makes power shovels and drills for mining companies. We saw a 14 percent spike in implied volatility in Bucyrus options yesterday; it's up at 67 1/2 percent against 60 percent historic volatility reading on the stock." (See video for more)

On Nokia ...
"Interesting activity in Nokia yesterday on back of the warning from Qualcomm , suggesting that there may be a lengthening of the cell-phone replacement cycle. What we saw in Nokia was a spike in implied volatility of 13 percent; this was occurring sort of part and parcel with the activity in Qualcomm. It's up, actually, by a third over the past week."

On semiconductors ...
"I did want to mention that implied volatility in a number of the semiconductors was elevated yesterday, not only on back of the defesniveness in Qualcomm and Nokia, but also Corning's warning of a softer demand for flat-screens, so keep an eye on implied volatility in the semiconductor names, as well as National Semiconductor , which reports earnings on Friday, which could also explain why we saw the 14 cent spike in implied volatility in National Semiconductor calls, National Semiconductor options yesterday. I did want to mention also that the volatility that we saw yesterday tended to favor the calls by a factor of about two and a half."
