The main U.S. stock indexes ended Thursday's trading in the red zone, which was affected by weak labor market statistics. The Dow Jones was down 1.65 percent, the S&P 500 was down 1.83 percent and the NASDAQ was down 2.05 percent.

Initial jobless claims rose more than expected last week to a 10-week high of 211,000. A week earlier the figure was 190,000 and analysts had expected a slight rise to 195,000. Secondary jobless claims also rose unexpectedly strong for the market, reaching a 14-month high of 1.718 million.

According to Cathy Jones, chief strategist at Charles Schwab, these results suggest that the U.S. labor market may be deteriorating, according to investing.com. The first two labor market reports released this year showed significant job gains, but experts warned that they were driven by seasonal and other factors rather than indicative of the strength of the U.S. labor market, the report said.
