    Greenspan - Best Story teller since Walt Disney

    Only one year after that he is now sounding alarms at ARM, IO, Optional ARM, etc, like craze. The fact that he is the best story teller is evident in that so many people became fancinated by his fair tales, but he has to reverse them so often that these fair tales become nightmares.

    That's why he is voted the best story teller since Walt Disney. Two stories by Greenspane stand out in my memory: 1. The wealth effect story in the late 90's. 2. The story of new mortgages (ARM IO etc) making the housing more affordable in 2004.

    Automated trading through Excel

    I use excel to monitor some market and a few selected stocks. The up-side is that it is very easy to do. The down-side is that the excel is very slow and not scalable (cannot handle a large portfolio), so I wrote a c++ program to do the bulk of analysis.
