US stocks opened up with gains on Wednesday, but quickly rolled over into negative territory amid a thin holiday trade.

The Dow Jones Industrial Average trades down 0.3% at 19,884.23, as of 12:25 p.m. ET, and remains unable ti reach the 20,000 mark.

The S&P 500 and Nasdaq also hold losses, with both down about 0.6%.

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.

A notable laggard on Wednesday is Nvidia, which trades down about 3% after short-seller Andrew Left’s Citron Research tweeted, “Citron readers know we have long been fans of $NVDA, but now the mkt is disregarding headwinds.”

Elsewhere, the US Treasury market is little changed with the 10-year yield hovering near 2.55%.
