Margin Debt, part II

We mentioned earlier [1] the recent rise in Margin. Have a look at the following chart:

NYSE Member Firm Margin Levels

The raw numbers are not what actually matter — and adjusting for inflation isn’t significant.

The reason Margin matters is that it is potentially revealing of extreme sentiment and/or speculation (margin clerks can do major damage in a downturn).

There are a few ratios I would like to identify and convert to oscialltors relative to Margin:

Total Margin / Total Market Cap

NYSE Margin / Account Assets

Margin / Trading Volume

Total Margin / Market Volatility

The idea would be to test these versus historical tops and bottoms . . .
