Wells Fargo analyst Christopher Harris upgraded Charles Schwab to Outperform from Market Perform and raised his price target for the shares to $50 from $42. Schwab's business is nearing an inflection point, Harris tells investors in a research note. He expects accelerating growth in "several key areas" and is encouraged by updated guidance from the company, which "infers considerably less interest rate sensitivity than previously noted and flexibility on expenses." This could drive consensus earnings revisions "from negative to positive," which should be a catalyst for the stock, contends the analyst.
