The liquidity of anyone's stock holding depends entirely on how much one holds compared to how much is routinely traded on the markets. If I own 0.01 percent of any heavily-traded stock, it's 100% liquid. I can sell it whenever I want at a moment's notice. In any such accounting it will be added to my liquid wealth. But if I own 25% of the same stock, it's illiquid. If I also run the company, then it's worse because any attempt to sell a large part of my holding will itself trigger a crash in the price.
