LONDON, Aug 27 (Reuters) - The yen rose broadly on Thursday, hitting its highest level in more than a month against the dollar and sterling as a slide in global stocks raised concerns a risk rally in past months may have been overdone.
The Japanese currency climbed to a five-week high against the dollar as European shares <.FTEU3> slipped 0.3 percent, taking a cue from a 0.7 percent fall in Shanghai stocks, which have been a driver of risk trades in past weeks.
"Risk sentiment is down. Asia stock markets were softer overnight, and that's resulted in demand for yen," said Kasper Kirkegaard, currency strategist at Danske Bank in Copenhagen.
He added that the yen was being boosted as some traders continued to cover short positions which had knocked down the Japanese currency last week.
Some in the market said a report that China's sovereign wealth fund would increase new foreign investment this year by around 10 times from last year, and was exploring investment in Japan, was also a support factor for the yen. [ID:nT204302]

Traders awaited a second reading of U.S gross domestic product for the second quarter at 1230 GMT. Expectations are for a 1.5 percent contraction rate compared with a 1.0 percent rate of contraction in the first reading. [USGDPR=ECI]
"The risk is that a downward revision may give the dollar some support from a risk point of view," said Chris Gothard, currency strategist at Brown Brothers Harriman in London, pointing out that a weak reading may increase risk aversion and trigger safe-haven flows into the U.S. currency.
China's cabinet said on Wednesday it would take steps to curb overcapacity and redundant investment in industries ranging from steel to wind power equipment, the official Xinhua news agency reported. [ID:nPEK160728]
Analysts said this may stifle improvements in the Chinese economy, which could have a negative impact on the nation's equities, at least in the short-term. (Editing by Andy Bruce)
