Oct 30 (Reuters) - An Apple-led surge in technology stocks lifted the Nasdaq to a record high on Monday, while the Dow and the S&P were weighed down by losses in healthcare stocks.
Gains were limited as investors assessed charges against Paul Manafort, a former campaign manager of President Donald Trump, and one of his affiliates - the first in connection with a probe into possible Russian meddling in the 2016 U.S. presidential election.
Apple was higher after research firms pointed to strong demand for the iPhone X. The stock provided the biggest boost to the three main indexes.
Merck fell 4.7 percent, setting up the stock for its biggest two-day decline, after the company said it had withdrawn an application for European use of its key cancer immunotherapy.
