Thursday's early trade: Dow breaks above 24,000 mark as tax bill wins crucial support

The Dow Jones Industrial Average pierced through the 24,000 mark for the first time on Thursday and the other indexes rallied on strong indications that President Donald Trump's tax-cut plan may get enough support for passage. Republican US Senator John McCain said he would back the tax legislation under consideration by the Senate, saying he believes it will directly benefit all Americans.
McCain, who had voted against the healthcare overhaul effort this summer, is considered a critical vote for the Republican effort. The blue-chip Dow index has crossed four similar 1,000-point milestones this year on the back of strong corporate earnings, robust economic data and hopes that Trump's tax plan would make headway.
"The market is pushing higher as the tax reform gets closer to becoming a reality. The market is beginning to price in a higher certainty of tax reform happening and that is the big driver today," said Mark Heppenstall, chief investment officer at Penn Mutual Asset Management in Horsham, Pennsylvania.
At 10:48 am ET (1548 GMT), the Dow Jones Industrial average was up 144.91 points, or 0.61 percent, at 24,085.59 and the S&P 500 was up 11.65 points, or 0.44 percent, at 2,637.72. The Nasdaq Composite was up 0.54 percent to 6,861.25, a day after posting its biggest one-day drop in more than three months as investors rotated out of technology stocks.
Tech heavyweights such as Apple and Facebook, the worst hit in Wednesday's sell-off, boosted the indexes on Thursday. Goldman Sachs jumped 2 percent, while JPMorgan and Bank of America rose more than 0.5 percent, tracking higher US treasury yields.
