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.

Broadcom (BRCM), maker of semiconductors for the communications industry, had a tough time in Tuesday's extended-hours session after the company released its latest earnings report. The stock went down 6% to a quote of $43.55. That was quite the reversal of fortune, as the shares had closed the regular session higher by 2.9%, settling out at $46.39. The 52-week high is $47.39, so the pullback might be considered a bit of a disappointment.

Then again, is a pullback in this name an opportunity? The business made, on an adjusted basis, 75 cents per share in the fourth quarter, according to MarketWatch. This was one penny better than the consensus estimate.

Friday's fourth-quarter GDP numbers offered more evidence that the economy is picking up steam, but one of the biggest obstacles to the recovery remains the stubbornly high unemployment rate. We'll find out whether there's been any movement on that front when employment data for January comes out this week. The Challenger Job-Cut report and ADP employment data are due Wednesday, and the government's unemployment rate on Friday. Another mild increase in jobs is expected, in line with the three-month average, but not enough to significantly reduce the unemployment rate.

Also look for the ISM manufacturing and nonmanufacturing indexes this week, as well as the Chicago PMI and the New York NAPM index. And Fed Chairman Ben Bernanke will speak to the National Press Club on Thursday.

The earnings crunch continues this week, and analysts surveyed by Thomson Reuters are anticipating lots of strong quarterly reports.

For example, year-over-year earnings growth from big oil Chevron (CVX), ConocoPhillips (COP), ExxonMobil (XOM) and Royal Dutch Shell (RDS.A) are expected to be in double digits. The same is true of many other energy and mining concerns reporting this week: Allegheny Technologies (ATI), Alliant Energy (LNT), Arch Coal (ACI), Cliffs Natural Resources (CLF), CMS Energy (CMS), CONSOL Energy (CNX), DPL (DPL), Hess Corp. (HES), Minerals Technologies (MTX), Pioneer Natural Resources (PXD), PPL Corp. (PPL), Southwestern Energy (SWN), Total (TOT), Whiting Petroleum (WLL), Williams Companies (WMB) and Wisconsin Energy (WEC).

The tail-end summer heat has been heavily attributable to the mergers and acquisitions blaze. Companies are putting their cash to work on public companies fetching discounted equity prices in a market environment favoring safety (e.g., gold and bonds).

Recently, Hewlett-Packard (HPQ) edged out Dell (DELL) for the 3Par deal award. With an eye toward the future, HP displayed their powerful desire to own a piece of the data storage and cloud computing pie. Since Dell ended empty-handed, it's only a matter of time before the next stock is a tech heavyweight's prime target.

Qualcomm Inc. (QCOM) may be at a tipping point right now. And for a stock that has seen four big price gaps during 2010, the move could be a big one. The question is, will the stock gap higher or lower?

Goldman Sachs -- citing influences like a higher mix of smartphones and tablets, the move from voice-to-data-centric devices in China and India and a weaker US dollar -- recently reiterated its Conviction Buy List rating for Qualcomm and raised its price target from $44 to $46.

The earnings crunch rolls on this coming week, and the analysts surveyed by Thomson Reuters are looking for strong quarterly results from the likes of Avon (AVP), Coinstar (CSTR), Corning (GLW), DuPont (DD), MetLife (MET), Norfolk Southern (NSC), Northrop Grumman (NOC), Royal Dutch Shell (RDS.A) and many others. In fact, Broadcom (BRCM), Chevron (CVX) and Southwest Airlines (LUV) are expected to have doubled their second-quarter earnings per share compared to a year ago.

The three months that ended in June saw Southwest Airlines celebrate the 39th anniversary of its founding, and it also declared a quarterly dividend. Analysts expect the Dallas-based no-frills carrier to report that second-quarter earnings came to 27 cents a share, a 70.4% rise from a year earlier. Revenue for the period is expected to have grown 20.4% to $3.2 billion. So far, analysts predict similar earnings and revenue numbers for the third quarter. But earnings results were better than expected in the past four quarters, beating consensus estimates by as much as 47%.
