Greg McBride, chief financial analyst at BankRate.com, says the Federal Reserve has little choice when it meets this week but to follow through on its signals and cut interest rates by one-quarter of a percent, noting that anything larger or smaller than that come Thursday would wind up being destabilizing for the market. The anticipated rate cut, however, may not move all interest rates as expected; McBride noted that mortgage rates actually have surged since the Fed's oversized first cut in September and they may not follow in lock-step with the next move either. Eric Balchunas, senior ETF analyst at Bloomberg Intelligence — co-host of the Trillions podcast — talks about the spate of new, unusual investing ideas that have been turned into ETFs recently — from BattleShares to the oxymoronic single-stock ETFs — and how most of them will go away when the stock market takes its next protracted downturn. David Trainer of New Constructs revisits WarbyParker — which he first put in the Danger Zone as it was launching its initial public offering, but which he says is even more radically overvalued now, and Eden Cooper, founder and managing partner at Drift Capital discusses crowdfunding classic automobiles and the return potential of classic cars.
