MMM is not an investment for every portfolio or every investor. For my income portfolio, I like this level as a good entry point. I had one position earlier at $160 and took another one today at $143 but will take several more if we continue lower. A dividend aristocrat yielding 7% on earnings and a 4% dividend seems like a good entry area if one has a 5-10 year investing horizon and is focused on dependable income. Chart from Y-Charts.
