Piper Jaffray analyst Sarah James attributes yesterday's post-earnings pullback in shares of Centene to the macro backdrop and the company's spending bump that she believes fuels the bear concern that constant spending for growth pressures margins. The analyst "strongly" disagrees and believe this is when investors should double down on Centene shares. The company will see the greatest multiple expansion in the group and has the highest potential for earnings upside, James tells investors in a research note. She raised her price target for the shares to $105 from $85 and keeps an Overweight rating on the name.
