If you want to buy and sell GEM stocks, you need to go to the securities company to open the GEM trading authority. At present, the exchange stipulates that all investors must have two years or more trading experience before they can apply to open the GEM. Take my ID card and shareholder card and go directly to the sales department. Investors can only participate in the subscription of new shares on the Growth Enterprise Market after the securities company confirms and opens the GEM transaction within the prescribed time limit.
