If you want to reduce speculation and uninformed trading, at least one way to do that is to give companies rights over who trades their shares and under what circumstances. You're not forced to sell your house to anyone, so why should you be forced to sell your company to anyone -- particularly day traders who will just introduce volatility and aren't in it for the long haul?
A long overdue organic reaction to the silly laws passed in the wake of the last financial crisis. No doubt we will see similar workarounds for the work of art that was "FinReg", though those workarounds may take the form of debuting on the Hong Kong Stock Exchange rather than the NYSE.
It's a little known fact, but Google also made use of certain legal workarounds to avoid going public for as long as possible (among other things, they split the company into two units of 499 people apiece, or so I recall).
