Copa is an airline stock that's well worth watching

Because developed market airline stocks have traditionally underperformed other sectors, investors frequently overlook emerging market counterparts -- such as Panamanian based carrier Copa.

Given the profitability of some firms in the sector, such dogmatic avoidance could be a mistake for investors seeking lucrative returns. One of the best emerging market airline stocks is Copa.

Copa originally ferried passengers to and from Panama City. Over the past few years however, it has evolved into an airline connecting passengers all over North, Central, and South America.
