Long-stock is not a leveraged transaction. When you buy a stock, 100% of the money is transferred to the person who sold it. That money has to come from somewhere. It may a loan from the broker.
I was referring to stocks and this is exactly what i have been trying to tell him.
Unfortunately English isn't my first language so my posts probably didn't make too much sense at times
It seems like he thinks that if he is the broker dealer he only needs to transfer a little bit of his own money and the exchange will provide the other part (the margin).
As far as i am aware that is impossible. If he is his own broker dealer he will need to put up 100% of the purchases value, since nobody is giving him a loan. Unless he takes a loan elsewhere, he will have no leverage.
Not including financing by short selling that is.
Correct me if i am wrong please.
