• The Fed looks set to raise interest rates for a 10th consecutive time at its May meeting this coming week. 
• A signal of a pause in hikes or a dovish Chairman Powell could ignite a rally in markets. 
• A portfolio manager said it may take a black swan event to prompt the Fed to cut rates this year.
