SPX crushes never stopped above MA 200.
Even FED pump of 3 trillion into market, buying even stocks of companies that are in bankruptcy, would be over.
Earlier or later the crush of -50% will happen as of people will need to sell something to pay bills - already 20% unemployed, 30% not paying rent or mortgage bills in time.
As long FED pumps money to keep the dead market breathing as hard would it be when the market will awaken.
In 1929 it was the speculators who pumped the market 4 times from 7 to 30 and it crushed below 7.
