BUZZ-JPMorgan dips after Oppenheimer downgrades stock to 'perform'

** Shares of biggest U.S. lender JPMorgan Chase JPM.N fall as much as 1.8%; last down 1.3% at $239.86, underperforming peers

** Oppenheimer downgrades JPM to "perform" from "outperform," stating that the stock has reached its target

** Brokerage notes that while most of the industry should see a steady rise in net interest income, JPM has forecast lower NII and that is what the consensus expects

** Oppenheimer says it is hard to imagine the stock outperforming, especially from the current levels, when its main revenue line is declining while others rise

** Wells Fargo WFC.N and Bank of America BAC.N shares dip 0.3% and 0.7%, respectively, while Goldman Sachs GS.N, Morgan Stanley MS.N and Citigroup C.N are flat

** Fourteen of 24 brokerages rate the stock "buy" or higher, nine "hold" and one "strong sell"; median PT is $237 - LSEG data

** As of last close, JPM shares up 42.9% YTD
