The U.S. economic calendar is thin and the market will continue to be vulnerable with the S&P and Dow industrials near record highs. However, the expectation of continuing accommodative monetary policy from the Federal Reserve should continue to lend support to equities.
"There's not strong enough evidence one way or another to change monetary policy," De Gan said, adding that with all the support the Fed has given to equities there are also "fundamental reasons" driving the market.
