Major U.S. stock-indexes lower on Tuesday after mixed earnings reports from major U.S. companies, weaker-than-expected data and further declines in crude oil prices.

Investors are also watching the Federal Reserve, which began its two-day policy meeting. While expectations of a rate hike this week are slim, traders will focus on the Fed's statement on Wednesday for clues on the timing of a liftoff.
