What you wrote here you could write every time, and yet, since end of June 2016, a week after the BrExit, trying to short the market based on such thoughts would have made you lose at almost every moment, and in the very rare moments when you got lucky, you would not have earned nearly as much as holding and riding the tide, which is guaranteed to rise over time due to inflation.
Once in a while, they let it crash, but trying to predict it based on yield curve invertion, or profit multipliers, or short term data like job reports or CPI or PPI or rate hikes fails more than delivers when trying to predict crashes like Gregory tries to sell here in order to get an interview in a doom and gloom channel of gold and silver sales business.
