March 7 (Reuters) - U.S. stocks pared losses late Tuesday morning as a decline in drug stocks, triggered by President Donald Trump's tweet about lowering drug prices, was countered by gains in technology shares.
Pharmaceutical stocks came under fire after Trump said he was working on a new system to increase competition in the drugs industry and bring down prices.

The S&P 500 healthcare index dropped 0.54 percent, setting it up for its worst day in more than five weeks.
Johnson & Johnson was the top drag on the S&P 500 and the Dow Jones Industrial Average, while Amgen weighed the most on the Nasdaq.
However, a 0.4 percent advance in the S&P technology sector , led by gains in Apple and Microsoft , helped offset the impact of the decline in drug stocks.
