- In the S&P 500's top 25, the average winner is up 61%, the average loser down 32.5%.
- Ownership by exchange-traded funds has played little role, with winners owned only slightly more often than losers.
- Dividends also haven't been much of a factor, with the average yield among the top 25 just 0.99%, compared to the 1.9% average for the 500.
