Why does the stock market fall?

I recall a story. British Prime Minister Winston Churchill was asked, "Sir, why is the stock market falling every day?"

His answer, "There are more sellers than buyers".

This is what is happening now to the global stock markets. Everybody (except Warren Buffett) is so negative. Nobody is buying. They expect the stock markets to fall.

The hedge funds have to liquidate their position due to withdrawals by the investors. They sell their holdings at any price. Some may be selling short. The wave after wave of selling will continue, until the value become $0. (Just joking. It will not reach this extreme point).

This is our wonderful global financial system, that has now totally collapsed.
