TheStreet Ratings team rates AMERICAN CAPITAL LTD as a Hold with a ratings score of C-. The team has this to say about their recommendation:
"We rate AMERICAN CAPITAL LTD (ACAS) a HOLD. The primary factors that have impacted our rating are mixed -- some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its solid stock price performance, good cash flow from operations and expanding profit margins. However, as a counter to these strengths, we also find weaknesses including deteriorating net income, disappointing return on equity and feeble growth in the company's earnings per share."
