Any of you watch this? http://www.nyxdata.com/nysedata/asp/factbook/viewer_edition.asp?mode=tables&key=50&category=8 Shows margin debt by month going back a long time. Worth graphing against the market. In the most recent crash, it was preceded by a reduction of margin debt. Margin debt spiked up, then reversed, then market crashed. We are now approaching similar levels of margin debt. I am trying tracking this to get an idea of when the next big drop may be.
