Wall Street fell on Tuesday, with the S&P 500 and the Nasdaq having their worst day in more than a month, following weak economic data and losses in technology and consumer discretionary stocks.

Pfizer, the largest U.S. drugmaker, maintained its full-year forecast, despite reporting revenue and profit above analysts` estimates, sending its shares down 2.3 percent to $36.44. The stock was the top percentage loser on the Dow.

"We are in an environment of mixed signal, inconsistencies and the markets are being driven by a lack of a positive theme, troubles in European banks and weak oil prices," said Andre Bakhos, managing director at Janlyn Capital in Bernardsville, New Jersey. 

"We`ve been setting up for squeezing of the sponge. It`s time to take some profits from the markets."
