Assuming you are bullish on the state of the market on the next 5-10 years what would be a healthy amount of margin to have as a % of your portfolio?? Even better is there a formula or paper written that would tell you the optimal margin % as a function of expected yearly average returns (obviously an assumption), % at which margin call is triggered, and margin interest?
I know large banks and hedge funds do margin optimization but they do it while also performing hundreds and maybe thousands of trades per sec (?). I am a long term investor so I am looking for long term margin investing.
From some research I have done in trying to find this margin optimization formula I think it has to do with the capital market line being closer to the risky investing side than to the safe one.
By the way I am expecting the optimum range to be between 5%-20% I really dont think that the right answer is 0% margin... Even at 115% investment if the margin maintenance is 30% I believe the portfolio would need to drop around 75-79% before getting a margin call, so even in the case of a major crash I think you would be safe.
Any good literature on this would be greatly appreciated. Specially if it has some good ol math
Thanks for reading
