While Charles Schwab's Q2 results were relatively in line with estimates, investors are underappreciating the downside risk to net interest revenue given the lower interest rate environment and the lack of growth in the company's balance sheet cash, Deutsche Bank analyst Brian Bedell tells investors in a research note. He sees the stock getting pressured on Friday during Schwab's business update, as he expects management to reemphasize a flat balance sheet this year along with an expectation for a net interest margin closer to 240 basis points versus a previous mid-240s expectation. Bedell lowered his price target for Charles Schwab to $41 from $43 and keeps a Hold rating on the name.
