In the stock market, if investors have less funds, such as retail investors, it is best to choose small-cap stocks with small circulation, because they are easier to realize, and investors with abundant funds are more suitable to choose stocks with large circulation.
If the total share capital is large and the non-tradable share capital is small, it is not easy for the banker to control the market and the stock is not easy to become a dark horse. On the contrary, the total share capital is small, and the non-tradable shares account for a relatively large proportion. It is easy for the banker to raise funds and open positions, which can quickly raise the stock price and become a dark horse. Without the intervention of the banker, the price fluctuation of large equity stocks is smaller than that of small equity stocks.
The total share capital is the total number of shares issued by a joint-stock company, and the circulating share capital may only be a part of it. For fully tradable shares, total share capital = tradable share capital.
