how much money do you make stocks?
500 shares of a $20 stock costs you $10,000, assuming you only use your capital. If you use leverage, which most brokerages will give you at 2 to 1 and some brokers will give you at 3 to 1, you lower the capital requirement. With 2 to 1 leverage, you need $5000 to make the $2500 profit.
