Union Pacific Corporation – UNP could be a low-risk buy here. It is very oversold, and is trading around the same levels that were support in late March. The last four times that it was oversold, in January, late February, May, and again in June, a rally followed. Depending on tomorrows action, I may go long. I'll be looking for a reversal pattern as my trigger. For example, if tomorrow's close is above today's low that could signal a reversal.
