This post is part of a special annual report -- Top Stock Picks '09 -- in which TheStockAdvisors.com asked 75 leading newsletter advisors to select their favorite investment for the new year.

"My top pick is US Cellular 8.75% Senior Notes (NYSE: UZG)," says Carla Pasternak. In her income-oriented advisory service, High-Yield Investing, she says, "The best thing about them? They are bonds, but trade like stocks."

Pasternak explains, "Their total interest payments of $2.1875 a year dished out quarterly are legal obligations, not discretionary payments like stock dividends.

"As senior notes, too, investors can rest assured that UZG's interest payments have a prior claim on the company's assets, ahead of any common or preferred share dividends, if the issuing company were to run into trouble.

"Not that I consider it likely United States Cellular (NYSE: USM), America's sixth-largest wireless firm and the name behind these bonds, is any danger.
