Baidu.com (BIDU - option chain) shares are rising today on reports that Google (GOOG) advertisers in China have been advised to switch to its rivals, including Baidu and Sohu.com (SOHU). This is on the heels of this weekend's report that Google will shut down its Chinese search engine rather than bow to the countries strict censorship rules. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on Baidu.

BIDU opened this morning at $570.48. So far today the stock has hit a low of $563.20 and a high of $628.50. As of 12:35, BIDU is trading at $581.05 up $30.81 (5.6%). The chart for BIDU looks neutral and S&P gives BIDU a neutral 3 STARS (out of 5) hold ranking.

Yesterday was a good day for Baidu (BIDU), the Chinese Internet search portal, after some Wall Street analysts noted that the departure of Google (GOOG) from China could "benefit Baidu tremendously."

BIDU has traded well in the United States, hovering in the upper reaches of the $380 region -- but GOOG's decision to operate in China without censoring local search results after recent cyber attacks pushed BIDU as high as $470 before the stock settled into the lower $400s.

Twitter-watchers have been expecting the company to make some move toward corporate microblogging capabilities for months now. This is one of the two directions that the social media platform has on its agenda for generating revenue, and it is likely the one with the greater potential. The other, serving ads on Twitter.com, is currently constrained by the fact that nearly 70% of Twitter use occurs away from the company's website.

While all talk of corporate accounts is still shrouded in speculation, the obvious plan would be for corporate users to have more robust analytics and other marketing tools for which a premium would be paid. Among the tools being rolled out ostensibly in advance of this business model is a multi-user account model, in which several "Contributors," as Twitter is calling them, can tweet under the same umbrella.

Google (GOOG) may be going after real-time search, but Microsoft (MSFT) isn't following. The company said on Tuesday that it doesn't see a pressing need to integrate with social media platforms such as Twitter and Facebook to deliver real-time results. According to Adam Sohn, director of Bing, Microsoft's search engine, "We're focused on our customers, not the competition."

Real-time search involves taking the freshest updates from social media platforms as soon as they are posted and including them in search results. For Google, the search engine segment leader by a mile, this has been a priority. In addition to Facebook and Twitter, Google has also inked an agreement with Yahoo! (YHOO).

Unless you already have a major foothold in the search engine market – or an amazing, disruptive technology that can make the world take notice – there isn't much point in staying. Competing with Google (NASDAQ: GOOG) is hard enough, even when you're Yahoo (NASDAQ: YHOO) or Microsoft (NASDAQ: MSFT) ... and, apparently, when you're IAC/InterActive Corp (NASDAQ: IACI). Barry Diller is ready to give up Jeeves, but only if asked nicely.

Diller's presence in the search space is Ask.com, ranked #4 behind Google, Yahoo and Microsoft's Bing. With a substantial gap between first and second, fourth barely registers at all. Ask.com has only a 2% U.S. market share, according to Hitwise, more than 60 percentage points behind the industry leader.

It's tough to take on Google (NASDAQ: GOOG). The search engine behemoth owns 65% of the U.S. search market and has a commanding brand presence. Yet, the software maker up the coast isn't known to give up easily. Microsoft (NASDAQ: MSFT) has cut a deal with microblogging site Twitter that should give it an edge in the battle to harness data and make it easier to find. A new deal will feed all those tweets into Bing, the Microsoft search engine.

Twitter is giving Microsoft full access to its data, in a deal announced Wednesday. Bing will provide search functionality for Twitter that you won't find in Google, which seems to have been outbid for the rights to the "tweet-stream." Under the deal, Bing will be able to index and display the tweets almost immediately as they are posted.

The number two search engine in the United States turned in a fantastic third quarter, far ahead of expectations. Cost-cutting, layoffs and business divestitures led to a surge in Yahoo's (NASDAQ: YHOO) profits and a 4.8% increase in share price in extended trading on Tuesday evening. Net income more than tripled to $186.1 million (13 cents per share) from the third quarter of 2008's result of $54.3 million (4 cents a share). Sales (exclusive of fees passed to partner sites) reached $1.13 billion, slightly above the $1.12 billion expected by analysts, according to a Bloomberg survey.

With the advertising market in rough shape and competition from Google (NASDAQ: GOOG) continually rising, Yahoo refocused on its core properties: the home page, messaging and mobile services. The company trimmed what it didn't need, which is why it was able to boost its earnings even with a decline in revenue. Increased ad revenue from auto manufacturers, travel companies and consumer product manufacturers also helped.

Yahoo's chief financial officer, Timothy Morse, says that the company's markets are "starting to stabilize." Of course, Yahoo itself must be doing something right: its share price is up 41% this year.

Some people join wine-of-the-month clubs. There are plenty of other programs out there, too, where your credit card is hit every month, and your purchase is sent to you directly. If only such programs were available for Google (NASDAQ: GOOG). . . .

The company's CEO, Eric Schmidt, said Wednesday that Google plans to pick up a small company a month as a way to get its acquisition head back in the game. With the worst of the recession behind us, Google believes, this is a great way to get moving.

After months of speculation, several media reports say that a deal to create a joint venture on search between Yahoo! (NASDAQ: YHOO) and Microsoft (NASDAQ: MSFT) may be announced as early as today.

Details of the transaction make the much-anticipated partnership seem immensely complex, which could undermine its future. Many analysts had expected Yahoo! to get up-front cash payments for putting its search business together with Microsoft's. That will not happen. The two firms will split the revenue from ads sold on their sites. Microsoft's Bing search technology will be the platform for the venture, but Yahoo! will sell the ads.

Google (NASDAQ: GOOG) isn't invincible. The search and online ad giant is expected to report lukewarm growth for the second quarter today because of a brutal market for advertising and redoubled efforts by Microsoft (NASDAQ: MSFT) to own a bit more than its meager share of the online market.

Good news would have to come in the form of a better mousetrap for growing Google's ad market and ways to keep the Redmond machine from tripping it up. Ultimately, analysts are looking to see how Google can get back to the double-digit growth that used to be a given.
