As we all know, the S&P500 is a cap-weighted index. In other words, the largest companies by market capitalization (AAPL, XOM ,MSFT, FB etc) represent the largest percentage weighting in the index. The bigger the company, the more important it is to the index. There are 10 (9?) sectors in the S&P500, and Technology is by far the largest one. Therefore one can argue it is the most important one.

When America’s largest and most important sector is crashing relative to it’s peers, is that a bullish development for the stock market? I would argue that it is not.
