The Market Crash Friday was NOT what you have been told.

The stock market crash was blamed on many things but NONE are true.
The reason why the stock market had a huge run down on Friday was due to
a VOID of BUYERS.
Who were the buyers???
You will never guess.
It was the 436 of the SP 500 companies that have buybacks underway, newly created, or open ended. Corporations have been supporting their own individual stock price.
WHY? To maintain their Market Cap during stressed market times.
To improve their dividend yield for the Buy Side Institutions who many 145 trillion dollars of assets and who own the bulk of those companies stock.
To keep their stock from dropping further on retail news.
Why did the corporations stop buying their stock on Friday?
Because the Earnings Season is getting underway this week and they stop buybacks to avoid a conflict of interest or other regulatory situations from buyin back shares during or before their CEO reports.
The corporations are likely to resume their accumulation a week or so after their CEO guidance and reports.
