"Investors have shied away from the big telcos in recent years because of concerns that their traditional businesses were shrinking," notes George Putnam III, an expert in uncovering turnarounds.

But now, he explains, "After years of concern about the cable companies invading their turf, the big telecoms are now well positioned to fight back."

In his The Turnaround Letter, the advisor looks at seven leaders in the global telecom space, all of which he says represent global leaders, with dominant positions in their local markets and the "potential to grow steadily by expanding the services they offer."

AT&T (NYSE: T) Putnam notes, gained control of Cingular Wireless due to its merger with Bellsouth. The renamed AT&T Wireless, he says, will account for about 35% of AT&T's revenues.

The advisor observes, "In addition to a strong wireless presence, AT&T is rolling out fiber-based landline services. With revenues expected to be north of $120 billion in 2007 and substantial operating cash flow, AT&T is a force to be reckoned with." Further, he notes, the dividend was just raised for the 22nd consecutive year, and the company is expected to repurchase roughly $7 billion worth of stock in 2007.
