Hello ors,
Thank you for weighing in on the article...I tried to write it so that it was applicable around the world and in various markets (e.g. equities, real estate, fixed income, etc.). So I'm thrilled that you picked up on the broad applicability - yea!
As for a piece about how to identify the bottom. I am not brave enough to venture such a piece as there is, to my knowledge, no such Holy Grail of market wisdom. Among the problems with such an endeavor are:
* Market participants have free will and they are free to change their mind at any time. This destroys the predictions made by any deterministic model, system, or theory. People do not behave in the ordered way that atoms do.
* Each market participant has a different time horizon in mind when they buy or sell. This clash of time horizons nets out each day in the level of financial markets. However, when you say "call the bottom" there is an implicit time horizon assumption in that question. Do you mean "all time" as in the preceding 200 years? The previous 2 minutes? Going forward forever more? You tell me the time horizon first and then we can hold that variable fixed and apply a model. Oh, but then we run into the free will problem above.
If you ever encounter such a delight as the market bottom caller that makes better than 50:50 predictions please promise you will come back here and share your finding with everyone!
With smiles,
Jason
