If you bought 1000 shares of a stock with the symbol MMM, what company would you be adding to your portfolio?

About as literal as you can get, 3M chose the symbol MMM for their stock, going public in 1946 on the NYSE. 3M stands for Minnesota Mining and Manufacturing Company, and it was initially founded in 1902, with the pointed goal of mining corundum, which is a type of aluminum.
