Just put an exponential mean, and the actual level slighly bellow that mean, and there is where we are. I see 700 the return to mean value.
And I agree that this graph is starting to get annoying.
There are always newbies who have never seen it... Doesn't bother me that much, especially since the bubbles DO follow a curve similar to it (but not exactly).
You mean they go up then go down? First there is an "up phase" then there is a "down phase", I now created an universal curve for any traded market in history, fits any time scale and any historical data! Feel free to derive your trading strategy from it! I use it to buy before "Bubble" phase and sell before "Crash" phase, works every time!
