The National Federation of Independent Business (NFIB) released its small-business optimism index for the U.S. on Tuesday. The index increased to 95.9 in August from 95.4 in July.
The increase was partly driven by a rise in job openings and earnings trends.
5 of 10 subindexes rose last month, while three fell and two were unchanged.
The NFIB surveyed 656 small business owners.
