BIDU traded up almost 6% on Wednesday after reporting quarterly earnings that raced past subdued expectations. The stock, which opened at $60 even, ended up the day at $54.73. Volume was extremely heavy, with over 5.6 million shares changing hands, compared to a normal daily average of 857k. The stock is still well of its 52 week high of $153.98, and you would have to say that the pullback after the gap up was extremely disappointing to investors who expected a stronger performance on Wednesday.
