(FORTUNE Magazine) – In the Pokemon universe, characters gain strength by "evolving" into superpowered versions of their primary-colored selves. Pokemon licenser 4Kids seems to have learned this trick well, emerging once again as the quickest of the quick. Joining it are 38 other veterans and 61 newcomers. To make the list, compiled by Zacks Investment Research, companies had to be based in the U.S., have been publicly traded for at least three years, and have revenue and market cap of at least $50 million. At a minimum, firms had to show 30% annual growth over three years in revenue and EPS, and positive earnings in the latest quarter and for the last four combined. The final order derives from the sum of the rankings of growth in revenue, EPS, and total stock market return over three years.
