LONDON, April 9 (Reuters) - European shares erased earlier gains in afternoon trade on Tuesday, with the FTSEurofirst 300 index dipping into the red after a muted start on Wall Street.
The pan-European index was down 0.1 percent at 1,164.25 points by 1346 GMT, retreating from an earlier session high of 1,172.07.
The benchmark U.S. S&P 500 index was flat in early deals , and aluminium major Alcoa added just 0.2 percent, confounding expectations for stronger gains after it posted forecast-beating earnings after the previous session's close.
"The dip came around the U.S. open, where the S&P is now trading unch (unchanged)," a London-based portfolio trader at a leading investment bank said.
"The market is considerably more bearish than it was a week ago," he added, citing the recent run of weaker economic data.
