R optimization

Hansi,There are several good packages in R for optimization. For your case, I would use "DEoptim" and use your restrictions as penalties in the objective function. Hope this helps!

Lunar Phases and Madoff

<r>I guess some of you have read articles that try to explain the relation between lunar phases and stock returns.
