BlackRock — Shares of the asset management giant rose 3.6% after BlackRock beat expectations on the top and bottom lines for the third quarter.

JPMorgan Chase — Shares of JPMorgan fell 2.6% despite the bank’s better-than-expected quarterly profit. Revenue for the largest U.S. bank by assets also came in higher than expected. The stock is up more than 26% this year. Other bank stocks also dipped ahead of earnings reports later this week. Bank of America dipped more than 1%, Wells Fargo shed 1.9 % and Citigroup fell about 1%.
