I read the book Chaos: A Very Short Introduction by Leonard Smith this summer. On page 146, he writes that Predco is a company that was formed by Doyne Farmer and Norm Packard who joined with other people who chose to be entrepeneurs rather than pursue post-docs. The company attempts to predict the markets based on non-linear dynamics. I suppose "non-linear" dynamics might not imply that fractal equations are used necessarily, but close enough. The author points out that the continued profitability of the company implies that they hit pay dirt. Predco is very tight lipped about their methods.

Anyone know more about this company?

Thank you so much for those links. Very interesting. The area of Fractals, chaos and complexity is quite a little rabbit hole. It seems to go deeper and deeper. I wonder if it finally comes out on the other side of the mirror. Lewis Carrol would have found this area of mathematics quite amusing, I'm sure.

Thx
