> Isn't the definition of a bubble that it has the capability to pop and then eventually pops? It's a description of a linear trend over a period that rises and falls. Why the trend falls (or how sharply) is not related. A housing "hump" isn't the preferred metaphor, although it's more apt. People like to think that a trend bubble has to "pop" because they imagine a physical bubble instead of a hump in a line.
