Win or lose, we've all got an opinion about which stocks are rockets and which are dogs. If we could invest like Peter Lynch or Mohnish Pabrai, we'd probably have a lot more companies in our win column than on the loss side of the ledger. Warren Buffett began buying railroads last year, and just about any company that ran on tracks came into play.

When top-notch investors back a stock, you might want to give it more consideration. Over on the investor collaboration site Motley Fool CAPS, we can do just that. On CAPS, players who've earned a rating of 80 or better by consistently outperforming their peers are dubbed All-Stars. Sometimes these ace investors will back a stock that others think is a dog. Considering the All-Stars' track records, we might want to look a little more closely at their selections.

Here are five companies that have been marked down by some investors, but enjoy unanimous All-Star backing:

Inventing opportunities
Pharmaceuticals and life-sciences marketing, communications, and staffing firm inVentiv Health has found that there are profits to be made by expanding its horizons internationally. While it has a presence in countries around the globe, its expansion into Latin America provides some unique opportunities that should build on its successes.

The segment provides nearly 20% of the company's revenues and saw 26% growth in the first quarter.
