Salesforce.com Inc CRM.N fell 2.3% in premarket trading after a report that UBS lowered its rating on the stock to "neutral" from "buy". Shares of oil companies and major Wall Street lenders continued their march higher, with Marathon Petroleum Corp MPC.N and JPMorgan Chase & Co JPM.N leading the packs. Interest-rate sensitive growth shares were also under pressure from a recent rise in U.S. Treasury yields, sparked by growing angst towards the prospect of interest rate hikes by the Fed to curb inflation.
