Time Warner Inc. (NYSE: TWX ) has been selected as the "undervalued stock of the month" by Paul Tracy, in his StreetAuthority Market Advisor.

The advisor explains, "We think the company's days as an industry laggard are over and we think the company is well-positioned to leverage its valuable assets and unlock shareholder value in the years ahead."

For those unfamiliar with the company's operations, he explains that Time Warner is the largest media conglomerate on the planet. First, he notes, there is AOL, which has built a powerful network of highly-trafficked web sites. He explains, "Its ubiquitous instant messenger service is used to send 1.8 billion messages every day."

Then, he adds, there is Time Warner Cable Inc. (NYSE: TWC), which has grown to become the nation's number two cable provider with a massive base of 15 million customers -- roughly half of whom have signed up for premium services such as digital video or high-speed internet.

The film business, he points out, includes Warner Brothers and New Line Cinema, and has "raked in billions" in global box office revenues from blockbuster hits like Harry Potter and The Lord of the Rings.

In fact, he says, Warner Brothers is planning to bring the Harry Potter world to life, unveiling plans to collaborate on a new theme park based on the "wildly popular" series.
