Barclays analyst Karen Short upgraded Dollar General to Overweight from Equal Weight and raised her price target for the shares to $125 from $102. The company is doing what all "best-in-class" retailers do, it is investing from a position of strength to enhance its competitive edge, even if it means near-term guidance disappoints, Short tells investors in a research note. As such, the analyst believes last week's post-earnings selloff in shares of Dollar General has created an attractive entry point. The company offers long-term growth and "rare defensive characteristics," says Short.
