Doug Roberts, chief investment strategist at the Channel Capital Research Institute -- author of "Follow the Fed to Investment Success" -- says that Jerome Powell is currently trying to live "the financial version of the Hippocratic oath, which says 'First, do no harm.'" Roberts says that Powell is trying to adjust expectations gradually, which is why Wednesday's statement from the Fed boss was benign, trying to play both sides, setting expectations at one rate cut this year but with the potential to avoid that if the data doesn't demand it. In the ETF of the Week interview, Todd Rosenbluth, head of research at VettaFi, takes a young, small fund that has struggled out of the gate -- X-trackers US Green infrastructure Select Equity -- and makes the case for making it a long-term holding and, in the Market Call, Stephen Dodson of The Bretton Fund talks about how his style of business value investing works in current market conditions.
