3M Company is at technical support, as we see nice and clean three-wave A-B-C correction by Elliott wave theory.
3M Company with ticker MMM is sitting at interesting 90 support area, especially if we consider equal wave length of waves A=C that stopped at the former wave 3 swing high resistance around that 90 area. A recovery back above channel resistance line and 210 region would be definitely signal that higher degree wave V is in progress, which would send the price back to all-time highs.
