Every week, I take a look at a few companies that surpassed their profit targets. Leaving Wall Street's pros with quizzical looks on their faces can be a good thing. It usually means that the companies have more in the tank than analysts figured and capital appreciation often follows.

Let's take a look at a few companies that humbled the prognosticators over the past few trading days.

We can start with Gmarket (NASDAQ:GMKT). South Korea's leading online marketplace saw second-quarter earnings climb to $0.30 a share, about 66% higher than last year's showing and well ahead of the $0.21 a share that analysts were looking for. The company was assisted by a tax break during the period, but would have easily smoked past the pros even without it.

Gmarket is keeping ahead of both Mr. Market and eBay (NASDAQ:EBAY) in the Web-savvy nation. It has now beaten Wall Street's guesstimates -- by double-digit percentage margins -- in each of the past three quarters.

Sohu.com (NASDAQ:SOHU) is another topper. The Chinese new media company can thank a hot online computer game for its runaway success. Quarterly profits soared sevenfold, to $1.02 a share, completely obliterating the market's expectations of net income clocking in at just $0.67 a share.

Sohu isn't the first nongaming Chinese stock to stumble into greatness in this niche. NetEase.com (NASDAQ:NTES) diversified out of its Internet portal and wireless content delivery services several years ago to become a market leader in Chinese Web games. Even enterprise software specialist CDC (NASDAQ:CHINA) is giving it a go these days.

Finally, we have IAC (NASDAQ:IACI) hitting it out of the park. Barry Diller's media conglomerate earned an adjusted $0.35 a share in what may be its last quarter as a stand-alone company. IAC is gearing up to split its empire into five distinct entities. IAC's bottom-line showing beat out analyst projections of $0.31 a share.

So, keep watching the companies that lap expectations. Over time, it will be a rewarding experience for investors as the market rewards the overachievers. That's the kind of surprise we look for in the Motley Fool Rule Breakers newsletter service.
