The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in.

(NYSE:INSP) stock is up an impressive 248% over the last five years. It's down 1.7% in the last seven days.
So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.
