Why Micron Technology, Eldorado Gold, and America's Car-Mart Jumped Today

Tuesday was down day on Wall Street, with major benchmarks losing a quarter percent or more. Market participants spent a lot of time watching the geopolitical situation, where a planned meeting between leaders of North Korea and the U.S. ran into possible hurdles.
