TheStreet Ratings rates Perma-Fix Environmental Services as a sell. The company's weaknesses can be seen in multiple areas, such as its deteriorating net income, disappointing return on equity, poor profit margins and feeble growth in its earnings per share.

Highlights from TheStreet Ratings analysis on PESI 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 Commercial Services & Supplies industry. The net income has significantly decreased by 4857.2% when compared to the same quarter one year ago, falling from -$0.63 million to -$31.38 million.
  • Return on equity has greatly decreased when compared to its ROE from the same quarter one year prior. This is a signal of major weakness within the corporation. Compared to other companies in the Commercial Services & Supplies industry and the overall market, PERMA-FIX ENVIRONMENTAL SVCS's return on equity significantly trails that of both the industry average and the S&P 500.
  • The gross profit margin for PERMA-FIX ENVIRONMENTAL SVCS is rather low; currently it is at 16.71%. It has decreased from the same quarter the previous year. Along with this, the net profit margin of -246.53% is significantly below that of the industry average.
  • PERMA-FIX ENVIRONMENTAL SVCS 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 two years. However, the consensus estimate suggests that this trend should reverse in the coming year. During the past fiscal year, PERMA-FIX ENVIRONMENTAL SVCS reported poor results of -$3.03 versus -$0.30 in the prior year. This year, the market expects an improvement in earnings (-$0.35 versus -$3.03).
  • PESI, with its very weak revenue results, has greatly underperformed against the industry average of 3.9%. Since the same quarter one year prior, revenues plummeted by 52.3%. Weakness in the company's revenue seems to have hurt the bottom line, decreasing earnings per share.

Guanwei Recycling ( GPRC) was another company that pushed the Materials & Construction industry higher today. Guanwei Recycling was up $0.04 (2.9%) to $1.41 on light volume. Throughout the day, 72,230 shares of Guanwei Recycling exchanged hands as compared to its average daily volume of 101,800 shares. The stock ranged in a price between $1.33-$1.46 after having opened the day at $1.36 as compared to the previous trading day's close of $1.37.

Guanwei Recycling Corp. manufactures and distributes low density polyethylene (LDPE) and other recycled plastics products primarily in the People's Republic of China and internationally. Guanwei Recycling has a market cap of $17.2 million and is part of the industrial goods sector. Shares are down 52.4% year-to-date as of the close of trading on Friday. Currently there are no analysts who rate Guanwei Recycling a buy, no analysts rate it a sell, and none rate it a hold.

TheStreet Ratings rates Guanwei Recycling as a buy. The company's strengths can be seen in multiple areas, such as its largely solid financial position with reasonable debt levels by most measures, attractive valuation levels, increase in stock price during the past year and notable return on equity. We feel these strengths outweigh the fact that the company has had somewhat weak growth in earnings per share.

Highlights from TheStreet Ratings analysis on GPRC go as follows:

  • GPRC has no debt to speak of therefore resulting in a debt-to-equity ratio of zero, which we consider to be a relatively favorable sign. Along with this, the company maintains a quick ratio of 7.54, which clearly demonstrates the ability to cover short-term cash needs.
  • Compared to where it was a year ago today, the stock is now trading at a higher level, regardless of the company's weak earnings results. Turning our attention to the future direction of the stock, it goes without saying that even the best stocks can fall in an overall down market. However, in any other environment, this stock still has good upside potential despite the fact that it has already risen in the past year.
  • GPRC, with its decline in revenue, underperformed when compared the industry average of 3.9%. Since the same quarter one year prior, revenues fell by 11.0%. Weakness in the company's revenue seems to have hurt the bottom line, decreasing earnings per share.
  • 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 Commercial Services & Supplies industry and the overall market, GUANWEI RECYCLING CORP's return on equity exceeds that of both the industry average and the S&P 500.
