China/Search-engine company/Baidu

CNN Money: Blue Baidu

"Baidu, the China-based search-engine company frequently referred to as China's Google, went public nearly three weeks ago and the stock soared 354 percent in its first day of trading."

"But since then, it's been all downhill. Shares have plunged 37 percent from the first-day close and are nearly 50 percent below the all-time high of $153.94 a share they hit on day 2."

"Even though the company reported late Tuesday afternoon that second-quarter sales more than doubled and that profits increased more than six-fold, shares tumbled more than 5 percent Wednesday morning on the news."
