After the stock is issued, the ex-dividend price is13/(1+1) = 6.50 yuan, which is higher than the allotment price of 8 yuan, so no one participates in the allotment (that is to say, at present, the share price is around 6.50 yuan, so you can buy whoever you spend 8 yuan money on, and the allotment is a voluntary behavior of investors with rights, that is, it is up to you to decide. If this happens, holding stocks will eventually make money (because stockbrokers in 8 yuan will not sell at a loss). Of course, we can also calculate the final ex-dividend price (6.50+0.2*8)/( 1.2)=6.75 yuan.
