- Suppose you had an accurate computer model of market behavior as well as
- an accurate set of initial state variables and enough Teraflops to run the

- As a small investor your actions will have little effect at first. The
- problem is as your model becomes better and your success grows then
- your actions will be noticed by other investors and they will modify
- their actions. You will create a system that is stable as long as you
- are not making money but will grow increasingly unstable the richer
- you become. It is not clear that you would be able to profit from the
- existance of such a predictor.
