Main Street is optimistic about how the economy is shaping up for the rest of the year.

According to a mid-year survey by Balboa Capital, an independent financing company, 65 percent of American small business owners "feel the economy will perform better" during the second half of 2015. The survey, which queried 35,000 business owners across all 50 states, also found that 48 percent of respondents believe the end of 2015 will be marked by "higher growth."

Thanks to the high levels of economic optimism, Balboa found, 33 percent of business owners plan to expand their operations this year, 20 percent to buy new equipment, 15 percent to increase inventory, and 9 percent to increase their marketing efforts.
