1.  Room to work
Although American Capital, like competitor Allied Capital (NYSE: ALD), has been struggling with losses, its large portfolio of investments has helped it book gains this yearthrough strategic exits. It recently made a $35 million gain from a sale to Corning (NYSE: GLW), and portfolio exits have helped it pay off about $300 million in debt since the beginning of the fourth quarter of 2008. Though the future is uncertain, many observers contend that American Capital has the resources to manage the tough environment.

2. Free cash flow
The economic downturn has had a wide-reaching effecton businesses as well as asset-management firms such as American Capital, Fortress Investment Group (NYSE: FIG), and Blackstone Group (NYSE: BX). Despite its struggles, American Capital has a solid history of generating strong free cash flowin all markets. It's grown its leveraged free cash flow at a healthy rate in recent years and has kept it coming in over the past 12 months.

3. Discounted shares
Picking up shares of a financial company such as CIT Group (NYSE: CIT), which is flirting with bankruptcy, because they're cheap may be a high-stakes gamble. But not all CAPS members lump financial companies in the high-risk categoryand expect companies such as American Capital and commercial lender CapitalSource (NYSE: CSE) to ultimately survive and prosper. With American Capital's shares selling below book value, some investors believe it's worth a closer look.
