I'm generally interested in statistical learning and optimization.

Richard- I didn't write $E\{...\}$ for any distributions. Also, I don't understand what your point is RE: $\mu_0 = \mu_1$. In that case the solution is a constant, but this is just a special case. In any event, since the OP is trading based on an HMM, it is quite unlikely that $\mu_0 = \mu_1$ here.

Added detailed proof of Sharpe ratio <> mean-variance equivalence. This is a standard result though.

This answer doesn't really address the question of selecting 5 stocks. You state "If you wish, you can...", but don't really justify your suggestion.
