Using formulae to emulate Buffett’s investment success as though it’s Physics LOL. Nevertheless, the study is interesting , but don’t think it is good idea for retail investors to have 60% margin which is very high. IMHO using moderate leverage is fine for experienced investors, esp when the market is low, but one should never risk what they can’t afford to lose.
