That is a good as theory as his to the plunge protection team.
Here is the origin:"
What Is the Plunge Protection Team?
The "Plunge Protection Team" (PPT) is a colloquial name given to the Working Group on Financial Markets. Created in 1988 to provide financial and economic recommendations to the U.S. President during turbulent market times, this group is headed by the Secretary of the Treasury; other members include the Chair of the Board of Governors of the Federal Reserve, the Chair of the Securities and Exchange Commission and the Chair of the Commodity Futures Trading Commission (or the aides or officials they designate to represent them)."
The team existed in some form but what they do is nothing like what some posters on here think they do. "Price discovery" is a term used by conspiracy theorists to portray something very basic ( like air and water ) as something more sinister. Basically it supposedly only exists when markets go down. It's all a bunch of baloney.
