Integrated circuit and systems software solution provider Qualcomm Inc.'s (QCOM) shares, first discussed here on January 28, 2011, at a price of $53.74, have pulled back about 10% to $54 in early 2011, but just view the retreat as a chance to scoop up shares, if you missed the January entry price.

And the reason is obvious enough: Qualcomm has the right products at the right time. The smartphone segment, aided by the 3G internet, is on fire, which has resulted in record model station modem (msm) chipset shipments.

Apple's (AAPL) iPad 2 got off to a great start during the first weekend of its launch, selling an estimated 400,000 to 500,000 units. Apple holds a substantial lead in the tablet market over competitors like Research In Motion (RIMM), Motorola Mobility (MMI), Dell (DELL), Samsung and LG Display.

How Much Will Suppliers Benefit from iPad 2 Sales in 2011?

Here we take a look at how much various iPad 2 component suppliers stand to gain from the product's success. We assume that Apple will continue to source iPad 2 components from the same set of suppliers throughout 2011.

Over the years, Marvell Technology (MRVL) has built a solid business in developing chips for PC storage. The problem is that, with the emergence of tablets, the market is feeling some pressure. While Marvell has been moving hard into the mobile space, the results have been muted.

So, it should be no surprise that the company's recent earnings report was fairly lackluster. In fact, the shares were off 8% to $16.75 in morning trading.

Mobile chips leader Qualcomm (QCOM) is planning to launch a variety of 'augmented reality' software for use in different consumer applications, according to Bloomberg/Businessweek.

Qualcomm wants to drive demand for its powerful processors that can handle high speed computing tasks for mobile devices. To do that, it intends to promote processor intensive augmented reality applications. Augmented reality aims to aid consumers with what they see. By pointing the phone's camera to objects and scanning them, the application can then identify them in the database, and find relevant material.

Qualcomm (QCOM) recently announced its fiscal 2011 first quarter earnings, in which it provided an outlook for the year. The notable positive here is the higher expected royalty rate in 2011, which reverses the trend of declining royalty rates in recent years. The tripling of capital expenditures that the company expects in fiscal year 2011 compared to 2010 also stands out to us, and we discuss the potential impacts of these below.

Qualcomm competes with other chip makers like Texas Instruments (TXN), Broadcom (BRCM) and Infineon (IFNNY), and we have a $53.82 Trefis price estimate for Qualcomm stock, which is around 4% below the current market price.

Coca-Cola (KO) has more than $13 billion in cash.

The top five companies (according to market cap) are:

• Exxon Mobil (XOM): $398.3 billion
• Apple (AAPL): $309.0 billion
• Microsoft (MSFT): $237.5 billion
• General Electric (GE): $215.0 billion
• Berkshire Hathaway (BRK.A): $202.5 billion

For years Microsoft (MSFT) was the tech leader. Then, Google (GOOG) came along and Microsoft missed the entire search engine revolution. But Microsoft still dominated in software. Then came Apple (AAPL) with its iPod, iPhone, and iPad. Again, Microsoft missed the small device revolution.

The Wall Street Journal reports that now Microsoft is playing catch-up again. With its next operating system it will use low-powered chips similar to those Apple uses.

Qualcomm (QCOM) is spreading its wings. It said Wednesday it has agreed to purchase Atheros Communications (ATHR) for $3.2 billion, as reported by the Associated Press. Why is Qualcomm making this deal? What are the advantages to the company?

Qualcomm is a big player in supplying chips to wireless phones. It has been looking to put its products in tablets and social notebook computers.
