Yay random walk! Love that book, wish it was taught in schools. I'm so curious what the day traders book says - does it promise you wealth and riches?
If you stay on a finance kick and haven't read them, some suggestions:
The Investor's Manifesto - I really understood asset allocation so much better after reading this
The Bogleheads' Guide to Investing - My finance bible
The Millionaire Next Door - Interesting write up, especially the notes on parenting
