On CAPS, 96% of the 946 members who have rated Harris & Harris believe the stock will outperform the S&P 500 going forward. These bulls include Zemko100 and Writerjeff2.

Just last month, Zemko100 described Harris & Harris in a purely positive light:

Venture capital group well positioned in a number of companies primarily involved with some aspect of nanotechnology. Very smart guys leading this parade. Sector diversification by people with real skin in the game.

Currently, Harris & Harris even sports a cheapish price-to-book ratio of 1.1. That represents a clear discount to much larger private-equity plays, such as Blackstone Group (NYSE: BX) (1.8), Fortress Investment (NYSE: FIG) (2.6), and Kohlberg Kravis Roberts (NYSE: KKR) (2.9).

CAPS member Writerjeff2 elaborates on the bull case:

Harris & Harris is a company that invests in start-up companies in nano-technology. The stock has been hurt by the recession and general absence of M&A activity in the technology sector. As the business climate improves TINY should see opportunity to cash in on some of its investments. Case in point: their portfolio company BioVex [was] acquired by Amgen. I expect to see more of this in the next two to four years.
