Rick Rieder of BlackRock told CNBC he believes the current investing backdrop is the best in history. He cited a large pool of cash outside markets, strong buybacks and low IPO supply as supporting demand for equities, and noted that bond markets also offer attractive yields. Rieder said valuation concerns are offset by companies’ ability to boost profitability—especially the Mag 7—and that long-term inflation expectations are around 2.5% with core inflation under 3%. He sees housing exerting disinflationary pressure and believes the Fed has room to cut rates; he also warned that productivity developments could lead to a sharp rate drop followed by a sudden rise in inflation. #BlackRock #FiatNews
