U.S. stocks fluctuated, after the biggest drop in three weeks, as health-care shares rallied on a U.S. Supreme Court decision while investors watched for a breakthrough in Greek debt talks.

HCA Holdings Inc., Tenet Healthcare Corp. and Universal Health Services Inc. jumped at least 7.5 percent after the Supreme Court upheld the nationwide tax subsidies that are a core component of President Barack Obama’s health-care law. Eli Lilly & Co. rose 4.2 percent after a favorable patent ruling. Netflix Inc. lost 2.7 percent, and energy shares slipped with oil.

The Standard & Poor’s 500 Index added 0.1 percent to 2,111.54 at 12:16 p.m. in New York. The gauge fell 0.7 percent Wednesday. The Dow Jones Industrial Average rose 14.61 points, or 0.1 percent, to 17,980.68. The Nasdaq Composite Index climbed 0.2 percent.

The S&P 500 is headed for a ninth week without a move of more than 1 percent, the longest streak since August 1993, as investors await a resolution to the Greek crisis while assessing data for clues on the timing of any Federal Reserve interest-rate increase.
