I generally trade in AMZN, MSFT, META and GOOG. They don’t go straight up and before the next earning report will drop 5-10% before going up again. I reduced my equity exposure to 60% after the sale which is high for my age which should be closer to 30%. I expect a drop at some point before increasing my stock exposure again.I can't find a market wide %.
