BAD WEEK: Major indexes fell more than 2 percent for the week, their worst weekly showing since a 3 percent drop the week ending June 1.
HOW COME? So-so earnings. Financial stocks fell even though Wells Fargo and JPMorgan results were generally better than expected. Results from Alcoa, Safeway and Yum Brands have been mixed. Chipmaker AMD's revenue is falling faster than expected.
WHAT'S NEXT: Third-quarter earnings continue, including Citi on Monday, Goldman Sachs and Intel on Tuesday, and Union Pacific and Verizon on Thursday.
