repeating the regression n times

[birsorumvar]

I have a data set consisting of 200 companies and their stock values for 70 days
I am trying to to regress each company value to bank interest rate for the same dates.

That is, doing regression (stock value over interest rate) for each company and get the betas from them.

Thanks.
