Corporations can tweet their financial results and other news. The ruling from the SEC allows publicly traded companies to release corporate news on social media sites as long as they tell investors which sites they intend to use. The decision came after controversy about Netflix CEO Reed Hastings, who said on his Facebook page that monthly online viewing by Netflix customers had exceeded one billion for the first time. The SEC said it will take no action against Hastings.

Apple used to be the hottest stock around. Certainly not now. Goldman Sachs has taken Apple off its list of most highly recommended stocks, joining other analysts in dialing back expectations for the company. Goldman analyst Bill Shope said in a client note that the iPhone 5, introduced last fall, hasn't sold as well as he expected. He says the company now needs some real "hits" among the products it rolls out during the second half of the year.

Apple plans to start production on a new iPhone, and a summer launch is possible, says The Wall Street Journal. Apple is also working on a cheaper iPhone model that could win it more market share in developing countries, the paper said, citing unnamed people "familiar with the device's production." The report is in line with the expectations of company watchers and Wall Street analysts. The iPhone 5 costs around $600, and while Apple maintains older iPhones in production, even those aren't cheap enough to compete effectively against low-end smartphones running Google Inc.'s Android software. The Journal said Apple is set to start production of the new iPhone within the next three months.

What's the size of the average tax refund? About $2,800 according to the IRS. For many people a big refund check is an excuse to spend money on travel, consumer electronics or some other treat. But John Kiernan, director of Industry Research and Analysis at CardHub.com, says refunds should be an opportunity to boost savings. "What we've seen a lot of in recent years is people are spending beyond their means and not really leaving themselves with the emergency fund they may need," Kiernan tells ABC News Radio. "If you have a little bit of extra money don't think 'Oh, I've got this cash burning a hole in my pocket.'" With credit card spending on the rise, he says, a tax refund can shore up the household budget. "The most responsible approach is to put it away in case of an extended period of unemployment or some other unexpected expense."
