On CAPS, 95.5% of the 934 members who have rated Harris & Harris believe the stock will outperform the S&P 500 going forward. These bulls include All-Stars Geofiz and imajerbear, both of whom are ranked in the top 5% of our community.

Just last month, Geofiz touched on the company's giant potential: "This is purely a bet that, over time, [Harris & Harris] will have invested in 1 or 2 'big ones'."

With more than 30 companies in its portfolio, Harris & Harris continues to be one of the easier ways to tap the exciting potential of nanotechnology. While Harris & Harris shares sit almost exactly where they did one year ago -- versus other private equity firms like MVC, Ares, and Gladstone, which are all up nicely over the same period -- many Fools remain attracted to the powerful tailwinds working in its favor. Not all of Harris & Harris' picks will become a smashing nanotech success, but imajerbear believes its winners should more than make up for it:

Nano tech is very quietly taking over the world with everything from nanotubes to nano-robotics to God only knows what being developed in some lab in some start-up company that Harris and Harris probably has a piece of. Swinging for the fences does cause strike outs but it also makes for a lot of home runs. Hold long term.
