Is it permissible to trade stocks by selling them on the same day that settlement and full ownership of the stocks are completed?

It is permissible to sell shares after acquiring them, even on the same day, as long as the company is established, has its activities, and its assets. As for selling shares immediately after subscription and before the company commences its activities, scholars have differed on its permissibility: some have forbidden it if it involves an increase, because it is the exchange of money for money with an increase. Others have permitted it, considering that the company has other assets besides money, such as the value of the license. However, after the company's funds have been converted into non-cash assets, it is permissible to sell them at the same price or with an increase.
