The National Federation of Independent Business released a survey on Tuesday showing a 0.8 point increase in small business confidence in September. The change brings the Business Optimism Index up to 88.9.

The NFIB wonders if this increase is a "start of a trend, or a blip." Rightly so -- the increase may have ended a six-month decline, but it hardly indicates positive sentiment. The increase was largely because fewer small business owners expect inflation-adjusted sales to contract.

Among the survey's findings, 28% of small-business owners reported poor sales as their top ranked business problem. However the NFIB reports poor sales has been the top concern for the past three years.

Furthermore, the net percent of business owners expecting better business conditions in the next six months landed at -22%, a dismal number that is still up 4 points from August, although 32 points lower than January.

"If that's your view of the world, of course, you're not going to hire, you're not going to buy new equipment, you're not going to do any of the things we need to get the unemployment rate down and raise GDP," said NFIB Chief Economist Bill Dunkelberg said in a CNBC interview.

So we were wondering, which small businesses are feeling optimistic about the future? To help find out, we collected data on micro-cap stocks with market caps between $100M-$300M (used as a proxy for small business sentiment).

To refine the list, we collected data on institutional and insider money flows and identified the companies that have seen significant net buying from those two groups.

Big money managers and insider executives seem to think these small companies have big-time potential -- do you agree?
