There was a time when PCs practically sold themselves, but that was before everyone started crowing about the tough economic landscape and other factors that, as Dell explains, makes growing a PC business "challenging," a word the OEM used when describing its second quarter financial results. Amid slumping sales and declining profits, Dell said it's in the process of transforming its business with a clear strategy focused on long-term results.

Auction site eBay is rolling in riches as its online business continues to boom. Revenue for the second quarter ended June 30, 2012 spiked 23 percent year-over-year to $3.4 billion, eBay said. Second quarter income on a non-GAAP basis reached $730 million, up 16 percent compared to one year ago, while GAAP income hit $692 million. PayPal is a big reason why eBay is doing so well these days.

Scanning AMD's financial report for the first quarter of 2012, you would think the Sunnyvale chip maker is in big trouble. Revenue was $1.59 billion, a nice number if not for the fact that it represents a net loss of $590 million, or $0.80 cents per share, along with an operating loss of $580 million. That's a 6 percent sequential decrease and a 2 percent decrease year-over-year. Non-GAAP earnings were $0.12 a share. So why wouldn't investors want to hit the panic button?

Record enterprise solutions and services revenue of $18.6 billion for fiscal year 2011 ($4.9 billion the fourth quarter) played a big role in Dell reporting its "most successful financial year ever." Revenue for the full year topped $62 billion, representing a 1 percent year-over-year increase, with $16 billion pouring in during the final quarter, a 2 percent increase over the previous year. But it was Dell's outlook for the coming quarter that didn't sit well with investors, who collectively sent the company's shares down more than 4 percent.
