STOCKS TO BUY: TheStreet Quant Ratings has identified a handful of stocks that can potentially TRIPLE in the next 12 months. Learn more.

TheStreet Ratings rates Professional Diversity Network as a sell. The company's weaknesses can be seen in multiple areas, such as its deteriorating net income, disappointing return on equity, weak operating cash flow and feeble growth in its earnings per share.

Highlights from TheStreet Ratings analysis on IPDN go as follows:

  • The company, on the basis of change in net income from the same quarter one year ago, has significantly underperformed when compared to that of the S&P 500 and the Internet Software & Services industry. The net income has significantly decreased by 266.9% when compared to the same quarter one year ago, falling from -$0.13 million to -$0.49 million.
  • Current return on equity is lower than its ROE from the same quarter one year prior. This is a clear sign of weakness within the company. Compared to other companies in the Internet Software & Services industry and the overall market, PROFESSIONAL DIVERSITY NETWK's return on equity significantly trails that of both the industry average and the S&P 500.
  • Net operating cash flow has significantly decreased to -$0.77 million or 2161.76% when compared to the same quarter last year. In addition, when comparing to the industry average, the firm's growth rate is much lower.
  • PROFESSIONAL DIVERSITY NETWK has experienced a steep decline in earnings per share in the most recent quarter in comparison to its performance from the same quarter a year ago. The company has reported a trend of declining earnings per share over the past year. However, the consensus estimate suggests that this trend should reverse in the coming year. During the past fiscal year, PROFESSIONAL DIVERSITY NETWK swung to a loss, reporting -$0.23 versus $0.27 in the prior year. This year, the market expects an improvement in earnings (-$0.19 versus -$0.23).
  • In its most recent trading session, IPDN has closed at a price level that was not very different from its closing price of one year earlier. This is probably due to its weak earnings growth as well as other mixed factors. Regardless of the rise in share value over the previous year, we feel that the risks involved in investing in this stock do not compensate for any future upside potential.

TheStreet Ratings rates Qualstar as a sell. Among the areas we feel are negative, one of the most important has been poor profit margins.

Compared to other companies in the Computers & Peripherals industry and the overall market, QUALSTAR CORP's return on equity significantly trails that of both the industry average and the S&P 500.
  • QBAK, with its decline in revenue, underperformed when compared the industry average of 9.2%. Since the same quarter one year prior, revenues slightly dropped by 4.6%. The declining revenue has not hurt the company's bottom line, with increasing earnings per share.

During the past fiscal year, QUALSTAR CORP continued to lose money by earning -$0.47 versus -$0.85 in the prior year.
