I think CEOs and higher ups are selling some of their stock before the 2 Infrastructure bills cost them more in taxes

 So, it is logical on many different fronts including what Powell of the Fed has said that people who are CEOS and higher ups who are investors are selling a lot of stock before they have to pay more in Capital Gains and other taxes next year. (Powell by the way is saying that interest rates are going to be raised by the Fed in order to dampen inflation but that isn't necessarily good for investors but is good for the average person who is not an investor. So, interest rates rising likely will mean inflation will begin to end and less new people starving because they cannot afford Gas or food to eat and get around to work and school etc.
