US stocks opened up with gains on Wednesday, but quickly rolled over into negative territory. Volumes are likely to remain light with many traders away for the holidays.
The Dow Jones Industrial Average trades down 0.1% at 19,925.71, as of 9:55 a.m. ET, and remains a threat to the elusive 20,000 mark. The index has threatened the psychological level for much of the past two weeks, but has been unable to climb above it for the first time.
The S&P 500 and Nasdaq also hold losses, with both down about 0.3%.
The Dow is trying for its eighth consecutive weekly gain, its longest streak since November 2013. Stocks have been on a roll since the election as investors cheered the prospects of President-elect Donald Trump's plans to to cut taxes, ease regulations, and spend hundreds of billions of dollars on US infrastructure.
Elsewhere, the US Treasury market is little changed with the 10-year yield hovering near 2.56%.
The economic calendar is light on Wednesday, limited to the 10 a.m. ET release of pending home sales.
