The Plummet Protection Team has been working every day buying huge numbers of call options on stocks in order to signal a turnaround. It has failed every day and they have now spent hundreds of billions.
If you understand which calls they are making and at what times they make them, then you can buy the corresponding put and make a lot of money. That he increased his investment by a factor of 9 in a week or so shows how much money we are talking about.
If the fed stops doing these daily calls though you can get holding the bag. Also in the event of a total collapse you can end up never being able to redeem your gains.
Elite traders know this game and are happily taking the billions that the fed is shoveling to them.
For the public, we'll see the elite doing well and able to afford the inflated cost of goods that results from pursuing this policy over an extended time period when it has repeatedly been shown to be a failing strategy since there are actual fundamental problems with the market right now, such as supply chain issues, likely loss of large numbers of staff, and upcoming mass unemployment and a global Depression.
