In fact, the sum total of investor negative credit balances are huge, even compared to days of the tech and the housing bubble. That’s very worrisome from a contrarian point of view because high negative credit balances, when investors are at their most optimistic, occur at some point before a major market break. Moreover, the huge level of margin debt also mean any downward moves will be significantly exacerbated by forced margin selling. These most likely occurred in march, when over-extended investors can’t meet broker margin calls. Thus, leaving plenty of margin left to be eliminated until we can to a positive credit balance.
