Colombian stocks that've increased the most in a year

Who cares about a stock that reached its all time high back in 2007? This list of companies at their 52-week highs is perhaps a better yardstick for recent performance, and consequently profit potential. As with all time highs, there are two ways to read this information: 1) that the business is doing well and probably will continue to do well as a result and 2) that it's getting into over-hyped territory and may retrace soon.
