I've been through the 1987 October crash, the 2000 dot com bubble and the 2008 financial crash. None of those markets had a combination of zero percent interest rates, huge financial stimuli/money printing, and huge liquidity. For sure this market will correct at some point, and probably pretty hard but as I recently heard, more money has been lost in anticipation of a correction than from the correction itself. It's really tough to fight the market. One just has to be prudent and agile in this particular market.
