A much-quoted survey of small business owners said that the economic confidence felt by this segment leveled off in June to halt a two-month rise. The dip, although not large, reflected increased unease about the near-term outlook for smaller firms. Cash flow issues led the list of concerns in the June report from the Discover Small Business Watch, a survey conducted monthly by Discover Financial Services. Of 750 small business owners polled, half (51%) reported temporary cash flow issues, up six percentage points from May. Overall, concerns about cash flow were chiefly responsible for driving down the survey’s confidence index to 86.1 in June from 87.4 in May despite some reported improvements in business conditions for the respondents. For example, although 43% of the owners said they planned to decrease spending on advertising, inventories, and capital expenditures, they were fewer in number than the 46% who said they planned to curtail investment in May. There was a slight increase (from 28% to 30%) in the number of those saying economic conditions for their businesses are improving, and a small decrease (from 56% to 51%) among those who rated the economy as poor. But these responses were offset by other answers signaling persistent doubt about how small business owners expect to fare as the global economy continues to churn. Sizable percentages of respondents said that their businesses had been negatively affected by the stock market (51%), the Gulf oil spill (30%), and the debt crisis in Europe (40%). Nevertheless, according to the survey, the shape of the economy over the last two years apparently hasn’t had a huge impact on the American entrepreneurial spirit. Better than half (53%) of those surveyed said they would not take a job for the same or more money, and fewer owners than last year would make the switch.
