On CAPS, 97% of the 4,228 members who have rated 3M believe the stock will outperform the S&P 500 going forward. These bulls include All-Star mrindependent, who is ranked in the top 2% of our community, and TheSmelloscope.

Late last year, mrindependent followed the lead of the Mad Money maven and got bullish on 3M: 

Cramer says this company will benefit from weakness in the US dollar. I agree. I also note that valuation is attractive given the stability and strength of this company, which also has the proven ability to continue growing sales.

Fools remain attracted to 3M's wide diversification and rock-solid financials. In fact, 3M's three-year average return on equity (29.5%) even tops that of rivals Avery Dennison (-3.8%), DuPont (27.8%), and Johnson & Johnson (27.1%), as well as other large conglomerates like General Electric (NYSE: GE) (12.4%) and Textron (NYSE: TXT) (3.8%).

CAPS member TheSmelloscope expands:

I'm impressed by the consistency of this company. Even during the recession they were able to keep turning a decent profit. And they didn't cut their dividend. ... It seems 3M is more effectively managed than others in the industry.

Even aside from its good looking numbers ... there are plenty of practical things to love about 3M. For example, they're everywhere. In fact, they make 55,000 different products. Yes. That's right. 55,000. ...

Yet even with so much success they keep pushing themselves. They have a passion for inventing. ...

One final thing I love about 3M is their CEO George Buckley. He seems like a thoughtful and very intelligent guy. In addition, he's a very serious scientist with several patents to his name. Pretty cool!
