3M Company (MMM)

[bar1080]

Many "MM or brokerage games" IHUBers complain about fade in importance with high priced stocks that are less often traded and held for years. No one plays games with BRK.A at $280,000, especially when the Berkshire Hathaway people are watching it.

And would you care if you overpaid a few cents for MMM if you bought it 40 years ago? Over the long run, short term upgrades and downgrades count for almost nothing. The company's success or lack of it drives the stock's price long-term.
