Sprint Nextel (S)Background: Sprint offers a comprehensive range of wireless and wireline communication services to consumer, business and government customers. Sprint was founded in 1899 and trades an average of 81 million shares a day and has a market cap of $14.3 billion. 52-Week High: $5.49 After last week's dip in price, Sprint really tore up the charts. It is still 18% higher than a month ago. Investors will want to monitor changes to see if short sellers dial up the warning signals. Otherwise, current short interest of 5.2% of the float is relatively small and not a major concern. Unsurprisingly, Sprint short interest has fallen quite a bit in the last month and a half. The new iPhone 5 will likely provide another boost to Sprint in two ways: Lower iPhone 4S prices will help Sprint meet contract obligations and a new iPhone product will increase interest in Apple products. I was in Sam's Club, which is owned by Wal-Mart ( WMT), this weekend and saw that an iPhone was priced at $149 with a contract. My wife was quick to point out that she would like one to go along with an Apple computer.
