"... Materials lists MON,DD, DOW, LYB, PX, FCX, IP, PPG and others, but not 3M.
“Materials” as a market sector has nothing to do with materials science (what 3M does)..."
We agree on 1st paragraph above, but you fail to recognize that every company listed in that paragraph
[MON, DD, DOW, LYB, PX, FCX, IP, PPG] necessarily engages in materials science as well. Your response, IMO, makes no sense.
And how or why does energy enter the picture? Another deflection, off the topic?
