So, in theory, if they get to, lets say $70 a share, I could buy them and sell them within minutes of each other and make a profit (minus brokerage fees of course)? I don't have the nearly $7000 to buy them anyway, but do brokerages allow for the purchase and sale without any money upfront? Meaning that they provide the purchase funds knowing that they are cashing out 2 seconds later?
