You are correct that C is much faster than perl at number crunching. In this case, perl is a screwdriver and the problem is a nail. Perl could compete if you use something like PDL to handle the math in matrix form.

Otherwise, you can write your own Inline::C or XS code to speed up your code. I think that Inline::C could work very well for your application. You can have the speed of C with perl's ease of development. An electric nail-gun!

For analyzing stocks I like R, especially as a post-processor for the data. It has CRAN, which takes after CPAN.

It should work perfectly the first time! - toma
