NEW YORK ( TheStreet) -- National American University Holdings (Nasdaq: NAUH) has been upgraded by TheStreet Ratings from sell to hold. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures and notable return on equity. However, as a counter to these strengths, we find that the growth in the company's net income has been quite unimpressive. National American University Holdings, Inc., through its subsidiary, Dlorah, Inc., engages in the ownership and operation of National American University, a for-profit university with various campuses in the United States. National American University has a market cap of $202.5 million and is part of the services sector and diversified services industry. Shares are up 4.4% year to date as of the close of trading on Wednesday. You can view the full National American University Ratings Report or get investment ideas from our investment research center.
