Full analysis of all these stocks is available at http://at.zacks.com/?id=2676.

Here is a synopsis of all five stocks:

Bull of the Day:

SINA Corp. (SINA) is a leading provider of online media and value-added information services to the global Chinese community. The company posted a year-over-year increase in revenue, but results were below our estimates. SINA provided encouraging Q2 guidance.

However, economic growth in the country has continued to slow during to the global downturn. The company is also facing severe competition in its mobile business, though China's Internet penetration has surpassed the world average, which is expected to have a positive impact on the company's business.

We believe the SINA's business will continue on the strength of solid fundamentals and it will emerge as a strong company when the recession ends. We maintain our Buy rating on the stock but increase our six-month price target to $38.00.

Bear of the Day:

Given the reduced visibility in the global economy, which progressively deteriorated during the quarter, Koninklijke Philips Electronics N.V. (PHG) has decided to restructure businesses in all three sectors, which led to additional charges in the Q1FY09. This has caused us to reduce overall revenue growth rate to negative 7.73% in Euro terms, for 2009 compared to negative 2.2% recorded for 2008.

The revenue growth rate in terms of dollars is projected at negative 17% for FY09 compared to 3.78% for FY08. The company is working to improve its cost structure and its EBITA margins have declined in 1Q09 due to restructuring charges booked.

Based on these results, we are maintaining our Sell rating on PHG with a price target of $17.00 or 24.9x 25.1x our 2009 EPADS estimate of $0.68.

Beige Book: Recession Moderating

Counter-balancing this was the expectation that there will not be "a substantial increase in economic activity" throughout the remainder of the year. Again, this is inline what with the trends I'm drawing from the economic and earnings estimate revision data. Conditions are improving, but we are nowhere near to getting out the woods.

On the positive side, signs of improvement were noted in import and export activity, discount retail and lower-priced homes. Though this might sound like good news for Masco (MAS) or Dryships (DRYS), it's important to note that we're still far from a recovery in housing or transportation.

On the negative side, credit remained tight. Several districts blamed the lack of lending activity for depressing auto sales, which is problematic for Ford (F) and other car makers.

Here are highlights from Wednesday's Analyst Blog:

China Denies Coke Acquisition

Today, the Chinese Ministry of Commerce announced that it has rejected The Coca-Cola Company's (KO) proposed acquisition of China Huiyuan Juice Group Limited, a Hong Kong listed company which owns the Huiyuan juice business throughout China. Citing the anti-competitive effects of the acquisition, the decision reflects the enforcement of China's strengthened anti-monopoly law and the internal political pressure of the Chinese government related to protecting indigenous brands from foreign control.

For The Coca-Cola Company, the strong performance of future key markets, like China, has mitigated volume concerns in North America. In 2008, unit case volume in North America declined 1%. Management is extending Coca-Cola's reach in emerging markets not only through the introduction of water and juice products, but also through acquisitions.

For example, in early 2006 Coca-Cola bought a Serbian water bottler, and in March 2007 Coca-Cola, in alliance with Greece-based Coca-Cola Hellenic Bottling Company (CCH), bought out Multon, which controls approximately 25% of the Russian juice market. On September 3, 2008, The Coca-Cola Company made a $2.3 billion cash offer to purchase China Huiyuan Juice Group.

Nat'l Semi: Buying Opportunity

National Semiconductor Corp. (NSM) is an OEM of analog and mixed signal integrated circuits. February quarter revenue fell short of consensus expectations, although the bottom line exceeded. Forward guidance is for a revenue decline of -5% to -10% in the seasonally strong 4th quarter.

Management has refocused R&D into areas that should drive margins. It has also initiated a massive restructuring program to further lower the breakeven point. Although National has been negatively impacted by the recession, the business continues to exhibit the necessary ingredients for a strong comeback. The necessary reduction of fab loadings will have a negative impact on near-term gross margins, but we expect margins to start looking up as restructuring actions are completed.

Buy SINA Corp. at These Levels

SINA Corp. (SINA) is a leading provider of online media and value-added information services to the global Chinese community. SINA posted strong financial results for 2008. Both its revenue and EPS once again exceeded the market consensus.

However, economic growth in the country had continued to slow owing to global downturn. SINA provided weak Q1 2009 guidance on account of a drop in advertising revenue. The company is also facing severe competition in its mobile business.

Vodafone's Strong Connection

We maintain our Buy recommendation for Vodafone Group PLC (VOD), the largest revenue generating international wireless carrier. The company's recent operating results are highlighted by strong growth in overall subscriber count bolstered by record customer additions in its Indian operation.

Additionally, solid growth in service revenue from emerging markets (in Asia and the Middle East) has been accompanied by sequentially improved results across most of the major European markets. Meanwhile, Vodafone continues to accelerate 3G wireless service deployments and expanding network availability across Asia, Eastern Europe and Africa, primarily through acquisitions.
