This post is part of a featured report on stocks in the Chinese online gaming sector.

"Perfect World Co., Ltd. (NASDAQ: PWRD) is a leading online game developer and operator in China; is our latest 'stock of the month' feature," says Dennis Slothower in his Stealth Stocks newsletter.

"The company primarily develops three-dimensional, or 3D, online games based on its proprietary Angelica 3D game engine and game development platform.

"Its strong technology and creative game design capabilities, combined with its extensive local knowledge and experience, enables the company to frequently and rapidly introduce popular games designed to cater to changing customer preferences and market trends in China.

One month ago, we featured a special report featuring the favorite China-based stocks among financial newsletter advisors. Since then, the 14 stocks covered in the report have risen an average of more than 15%.

The performance of these stocks -- along with the overall China market -- has far exceeded the 3% gain in the S&P 500 index over the same time period. That report can be viewed here.

Despite these gains, many of the leading advisors remain bullish on China; in particular, several have recently focused on the online gaming sector in Asia. Indeed, Timothy Lutts notes that while the video game market in the U.S. is slowing, the video game market in China is expected to show 20%+ annual growth in coming year.

Much of the attention this week will no doubt be on how the impending General Motors (NYSE: GM) bankruptcy will shake out, as well as the usual economic concerns: Has the housing market bottomed? Will oil prices keep rising? Is the employment situation getting any better? And so on (see highlights of the economic calendar below).

What probably won't get much attention are quarterly earnings, as the earnings season for this quarter winds down. But there are a few reports that analysts surveyed by Thomson Reuters have high hopes for.

While much of the attention was on the upside surprise offered up by Lowe's Companies Inc. (NYSE: LOW), Hastings Entertainment Inc. (NASDAQ: HAST) and Perfect World Co. Ltd. (NASDAQ: PWRD) also reported beating earnings expectations Monday.

Leading multimedia entertainment retailer Hastings reported that, for the three months ended April 30, it earned about $1.7 million, or $0.17 per diluted share. That compares to a profit of $0.28 per share a year ago, as well as to $0.13 per share forecast by analysts surveyed by Thomson Reuters. First-quarter revenue decreased 4.7% from a year ago to $125.7 million.

Last week we got a good look at how the apparel retailers have been doing when JCPenney Inc. (NYSE: JCP), Kohl's Corp. (NYSE: KSS), Nordstrom Inc. (NYSE: JWN), and Urban Outfitters Inc. (NASDAQ: URBN) all reported better-than-expected earnings for the most recent quarter. On the other hand, Abercrombie & Fitch Co. (NYSE: ANF), Eddie Bauer Holdings Inc. (NASDAQ: EBHI), Liz Claiborne Inc. (NYSE: LIZ), and Macy's Inc. (NYSE: M) reported quarterly losses, reflecting the ongoing reluctance of consumers to spend.
