I really like this definition because it is understandable. However we do not know long term where the stock market will be. There are countries that have been wiped out and their stock markets decimated (e.g. country that had a revolution). The US stock market is an exception in that distribution.

Perhaps you mean macro vs. micro as in economics. Even there micro is far more predictable than macro. Macro is almost voodoo when it comes to prediction of any sort on any timescale.
