U.S. small business confidence fell in January to its lowest level in nearly two years amid worries about the near-term outlook for business conditions and sales growth, consistent with a recent slowdown in economic growth.

The National Federation of Independent Business said on Tuesday its Small Business Optimism Index fell 1.3 points to 93.9 last month, the weakest reading since February 2014. Still, small businesses remained fairly upbeat about the labor market.
