Waiting for the price to go up
As you can see, the shares for company A are available for 100 rupees each. Go ahead, buy some shares.
company A: ₹ 100
Great, you bought XX shares for 100 rupees each. Now, let's sell them to make a profit.
Wait, but nothing happened. We didn't make any profit. Why did no one buy our shares at 110? Because, the market is still selling the shares at 100 rupees. Why would someone buy at 110 from you if they can buy at 100 from the market?
We'll have to wait till the price of the share goes up to 110 rupees.
