The S&P 500 is up 7.6% year-to-date.

Their outsized contribution to the index's performance is evidenced by the returns of the S&P 500 equal-weighted index, Edwards said, which is down by 5% this year.
In the equal-weighted index, each individual S&P 500 constituent's performance impacts the overall index's performance the same.
