The Materials sector is the second smallest of all the 11 sectors in the S&P 500 index. At just a 2.5% weighting, it’s worth less than each Apple, Amazon, Microsoft, NVIDIA, and Alphabet. And if you stripped out the Materials’ largest component, which makes up one-fifth of the 29 member sector, you’d be left with a group that’s setting new multi-year lows when compared to the rest of the large-cap equity market.
