The stock market's pre-election funk has extended into an eighth straight day, marking the longest losing streak for a key benchmark since the 2008 financial crisis, the AP reports. The Standard & Poor's 500 index took another turn lower Thursday as investors worried that Election Day could upset the status quo in Washington and the US economy. The losses for US stocks were modest but broad. Health care and technology companies fell more than the rest of the market, and several companies declined after reporting disappointing earnings or outlooks. Fitbit plunged 34% and Facebook lost 6%. The Dow Jones industrial average slipped 29 points, or 0.2%, to 17,930. The S&P 500 fell 9 points, or 0.4%, to 2,088. The Nasdaq composite lost 47 points, or 0.9%, to 5,058. (More Dow Jones stories.)
