Bubble popping?

I am not saying this will happen, personally sitting in 80% cash besides a few stocks that I still see upside in the next couple months, but could you imagine the pain if this played out. bearish divergence on the monthly Fed turned hawkish. Before you say it couldn't, the 2008 financial crash was 53%. 2000 dot com bubble 60%. Will tech pop this time? or will govts find another way to keep the market going?
