Sentiment continued to be supported by the comments from Bernanke on Wednesday, which was interpreted as being "dovish" and suggested the Federal Reserve may not be as close to unwinding stimulus as previously expected.
Both the Dow and S&P500 rose to all-time highs, and closed 1.1% and 1.4% higher respectively.
The Euro-Stoxx also gained 0.8%, although political uncertainty in Portugal may have capped gains (see below for details).
US treasuries were volatile, but continued to gain support after Bernanke signalled stimulus would remain. Yields on 10-year notes fell, and have pulled back from near two-year highs.

Leading indicators of employment suggest the current soft patch the labour market will linger.
A breach of 6% in the unemployment rate later this year, therefore, is a possibility.
The most worrying aspect of the data lies with what is happening in full-time employment.
There were only 64k full-time jobs created in the year to June, not much of an improvement on 2011/12 and significantly down on the 214k jobs created in 2010/11.
Part-time job creation is picking up some of the slack, but not enough. Subdued levels of confidence among businesses are keeping hiring intentions modest.
The jobs outlook suggests the pressure remains on the RBA to tap on the accelerator again.
