CNBC"Street Signs" May 22, 2008

Against the backdrop of turbulent markets and a less robust economy, the Calamos investment management team is finding a wide variety of long-term opportunities. In the May 22, 2008, broadcast of CNBC's "Street Signs," Nick Calamos highlighted two companies that meet his team's growth criteria.

In this broadcast, the co-chief investment officer of Calamos Investments discussed his positive outlook for IHS, Inc., a company in the industrial sector that provides software, data, and parts services for the energy, construction, and aerospace industries. IHS, Inc. offers the Calamos team a strategy for tapping into longer-term secular trends (such as infrastructure building), with reduced cyclical vulnerabilities common to many traditional industrial companies. IHS, Inc. is also positioned to benefit from the energy sector's growth, but is less directly tied to volatile commodity prices. Nick cited the company's high return on invested capital as another compelling merit.

Within the technology sector, the Calamos team is bullish on Dell Computer. "I think it's a very cheap stock right now, with free cash flow yield of about 9%. [Dell is] buying back stock. Michael Dell is back at the helm … the right guy is in charge and we're excited about the stock," Nick said. As the economy slows and consumers become more cautious, Nick believes that Dell offers "good upside in a market where low-cost producers should be winning again and [Dell is] on a cost-cutting focus right now."
