Yahoo! (YHOO) is an easy target to assail.. just look at this chart, which shows utter misery over the past year, but beyond that, shows utter non performance vs the price performance of Google (top of chart).
http://www.theflyonthewall.com reports this bit of intelligence:
"YHOO is expected to report EPS of .13 cents on 1/23. AMTR say's "conservative Guidance is expected; we still like YHOO in 2007." YHOO call option volume of 74,440 contracts compares to put volume of 48,653 contracts. YHOO February option implied volatility of 47 is above its 26-week average of 35 according to Track Data, suggesting increasing risk. :theflyonthewall.com"
