Oddly, in a bubble the highest valuations come just before the burst. This is obvious mathematical certainty that can be read by anyone viewing an exponential growth curve.
I mean that as valuations rise before a bubble bursts, the curve provides that successive values grow, sometimes at an increasing rate. The greatest values, and change in values comes just before the bubble bursts. The point being that high valuations and increasing valuations are not very capable of distinguishing bubble/non-bubble. In fact, tulips were most valuable, and those values were climbing at the highest rate before the tulip bubble burst.
