Why The S&P 500's $100 Billion Club Matters
Because the index is weighted by market capitalization, the bigger companies have a bigger impact on the way it moves.
In a new note to clients, Morgan Stanley's Adam Parker discusses the $100 billion club: the companies worth more than $100 billion:
There are 35 stocks listed in the US that each have a market capitalization greater than $100 billion. Combined, these stocks are $6.9 trillion of market capitalization today, representing 40% of the S&P 500's market capitalization and 44% of earnings... The fact is, these 35 names matter deeply for the performance of most benchmarks, and the competitive impact of these companies affects nearly all US companies at some level. For a long time, hedge funds had an anti-mega-cap bias, underweighting these names in favor of stocks less than $100 billion in market capitalization. Is that smart? This $100 billion club is one where historically a sizeable amount of alpha can be generated...
So, 7% of the companies account for 40% of the S&P 500's market cap and are responsible for 44% of earnings
