I agree supply and demand sets the share price. But demand depends on a company's performance and the market cap and not on the number of shares or the share price. Whether they have 700,000 shares at $30 or 7 milliion at $3 makes no difference or should make little difference to investors, although it's easier to buy board lots of a $3 stock than one trading at $30.
All I'm saying is that investor interest comes mainly company performance and secondarily basedon the share structure which is mostly what's talked about on this board.
