Monsanto has had a poor history as an long-term investment…
You must be thinking of a different company. MON was spun off by the drug company, Pharmacia in an IPO at a split-adjusted price of $10/sh in Oct 2000; since then, the share price is up a whopping 645%, which equates to a compounded annual return of about 50%!
Sales and earnings have increased at a similar rate during the past 11 years.
