Where to begin with 3M (NYSE: MMM)? The company defies description. It’s a little bit of a consumer-products company, partly an industrial chemical company, party a healthcare supply company. It makes money, too. Quite a lot of it — more than $30 billion in revenue last year. The real question, though, is whether you’re likely to make money by adding 3M stock to your portfolio.
