has ever correctly predicted financial booms/crisis in the history of financial markets. These things don't work according to logic.
A logic can be drawn only after the event .
These are black swan
events , very difficult to predicted, occurs when least expected and
made to look obvious by "experts" after its occurrance.
IMHO, the next boom will also tread on the borders of being a black swan , if not a full black swan . Maybe a grey swan .
A sector, completely unkown now, might take the charge and lead the next boom. Technology might not lead . You'll then have people scrambling to get into that sector,
like what happened in IT in the 90s. The boom might be of a magnitude unheard of before . Massive and enormous , dwarfing the previous booms .
May be a boom might never happen for a hundred years and we might suddenly find ourselves in the midst of a third world war . I am somehow convinced that its not
going to be on the lines of the previous boom .
Anyone close to a correct prediction and taking steps accordingly (taking up work in correct sector or buying stocks which are dirt cheap now but might become another google later on) is going to very rich.
