JPMorgan analyst Kenneth Worthington lowered his price target for Charles Schwab to $59 saying the company's business model has increasingly become dependent on earnings generated on customer cash. While its transition from sweep money funds to the bank "remains robust," investors have been concerned about lack of average earning asset growth, Worthington tells investors in a research note. He believes Schwab will see growth trough in May with June data, with growth picking up seasonally June through the seasonally strong December. The analyst keeps an Overweight rating on the shares.
