When investors think that the stock price is too high or too low, they can make the stock price more reasonable by selling the margin and selling the margin, which is helpful to the formation of the internal price stabilization mechanism in the market.

Two, margin trading can enlarge the supply and demand of funds and securities to a certain extent, increase the volume of pactions in the market, thus activating the stock market and increasing the liquidity of the securities market.
