Asia equities are set for a sluggish open on Wednesday after Wall Street pulled back from record highs reached in previous sessions, as investors eye the upcoming earnings season for more signs of a recovery following a series of strong U.S. economic data.

The three major Wall Street indexes closed lower on Tuesday, a day after the S&P 500 and the Dow rose to record levels driven by optimism from a greater-than-expected jobs report last Friday and data showing a dramatic rebound in the U.S. services industry on Monday.
