"History shows very little evidence that sector peaks are related to the size of a sector's single largest component. In fact, history suggests investors looking for bubbles among sectors in the S&P 500 would be better served to look for sectors with broadening, not narrowing, market cap concentration," said Gina Martin Adams, institutional equity strategist at Wells Fargo Securities.
