The greatest dependence on the top 10 stock return contributions this century
Exhibit 6 compares the return contribution generated by the top 10 stocks and compares them to the respective aggregate market returns. In the final year of the TMT bubble the market returned 24.1% with the top 10 stocks contributing 9% (over 1/3rd)of the aggregate return. So far in 2023 the market has returned 8.8% with the top 10 stocks contributing 8.4% (95%) of the aggregate return. In this respect the market is delivering the most concentrated returns this century.
