UnitedHealth Group is down 12 percent in the third quarter so far, according to The Wall Street Journal.
At that rate, the health insurance giant is nearing its largest quarterly drop since June 2010, according to the report. In premarket trading on Sept. 30, UnitedHealth was down 0.7 percent.
Barron's noted on Sept. 26 that UnitedHealth "could be the best political indicator in the stock market." UnitedHealth hit a low in April with the introduction of a "Medicare for All" House bill.
New lows could signal investor concern around Democratic presidential candidates challenging President Donald Trump in 2020, especially in the wake of the House's recent impeachment inquiry, Barron's noted.
