does any other "fixes" come to your mind regarding data analysis in matlab? like something along the pinv type fix?

Can't think of a major fix right now.

If there are higly correlated inputs one could also use Principal components analysis (PCA)

Here is the Matlab link:

There are lot of good tutorials on it online.

One interesting anecdote (this is not first hand - you might be able to verify or deny it) I read at wilmott was that DE Shaw used it as their first strategy to trade a basket of stocks, becasue some of the components were predictable. But since then, it has been eliminated.

Once I checked out the strategy on one sector and it was seemed pretty useless.

So it is unlikely that OP's strategy would be very scaleable....but maybe he is onto something.
