Hi,

Hope all is well. I am quite new to STATA and was using this forum a lot while I was studying a course in Empirical Finance. Now I am working on an event study but I'm having trouble with my data and I can't figure it out. It is a very basic but it is driving me nuts.

My data set is all stocks listed on Nasdaq Copenhagen. Currently, each firm is a separate variable. My problem is that I'd like all firms to be in one single variable, but I don't know if there is a way I can mass reshape all of the variables.

Please the picture below for my current data set(parts of it).

Sorry for the trouble.

Best regards,
Nima
