Dec 7 (Reuters) - The S&P 500 and the Dow hit record intraday highs on Wednesday, helped by gains in bank stocks, but President-elect Donald Trump's comments on drug prices slammed the healthcare sector, pulling down the Nasdaq.
Trump, in an interview with the Time magazine, said he would bring down drug prices.
The S&P 500 healthcare index swiftly lost nearly 2 percent, while the Nasdaq Biotechnology index dropped 3.8 percent - set for its worst day in nearly two months.
Trump's effect was also seen on Tuesday, with Boeing's stock falling after his tweet that an order for a revamped Air Force One plane should be canceled as it was too expensive.
"I think it is a new fact of life going forward, that fundamentals can be swept aside any day by comments from the (President-elect)," said David Donabedian, chief investment officer of Atlantic Trust Private Wealth Management.
