Wall Street is seen sporting caution, as it heads into the day that also has the FOMC meeting on its calendar. The index futures point to a narrowly lower opening on Tuesday. After Monday’s lull, more earnings news continues to flow in, with Alibaba (BABA), Comcast (CMCSA), Ford (F), DuPont (DD), Pfizer (PFE), Merck (MRK) and UPS (UPS) among the notable companies lined up to release their quarterly earnings release. A 2-day FOMC meeting starts later in the day, although a decision is not expected until Wednesday.
