MMM has been at somewhat of a discount in my opinion for a while now considering their steady dividend of $1.50, MMM not having lowered dividends in the recent past. The P/E is 9.77 which is great for a company that is a leader in their market and a larger cap stock. The price to book is a little high at 3.4 but lower than a lot of more overpriced stocks that make as much profit.
