Yellen, Janet L. on 2018 February 4 at 09:00
Well, I don't want to say [asset prices are] too high. But I do want to say high.
As for whether Yellen's view that the stock market (which plummeted on Friday) has been too high in recent months: "Well, I don't want to say too high. But I do want to say high. Price-earnings ratios are near the high end of their historical ranges. If you look at commercial real estate prices, they are quite high relative to rents. Now, is that a bubble or is too high? And there it's very hard to tell. But it is a source of some concern that asset valuations are so high. Yellen, Janet L.
