I used to be a margin clerk. You don't have to explain margins to me.
In that case, could you explain your apparently sarcastic response to me:
In 1929, every Tom, Dick and Harry was buying hyper-priced stocks on margin and with ......interest only loans.........Polybius
Yeah, margin loans are interest only. Duh.........Toddsterpatriot
As I understand it, in the 1920's, besides using margin accounts, people were also borrowing money with interest-only loans secured by their own real property, not securities, in order to get even more cash to feed their stock market speculation.
How is that the same as having a margin account with their broker to the point that it deserves a "Duh"?
