European stocks ended the day in the green on Tuesday, after fluctuating throughout the day.
The pan-European FTSEurofirst 300 provisionally closed up around 0.3 percent at 1,358.55 points, with all major indexes ending flat-to-higher. Spain's benchmark IBEX lead the gainers, closing up approximately 0.7, while the U.K's FTSE 100 ended around 0.2 percent higher.
In the U.S., stocks crept higher, with benchmarks setting intraday records, even as investors found little impetus to move decisively in one direction or the other.
Earlier in the day, Philadelphia Federal Reserve President Charles Plosser expressed concern over low interest rates in the U.S., which he said are unprecedentedly low. "There are many indicators that tell us interest rates are too low," Plosser, who is one of the Fed's most outspoken "hawks", told CNBC.
