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 LightPath Technologies as a hold. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures and good cash flow from operations. However, as a counter to these strengths, we also find weaknesses including deteriorating net income, disappointing return on equity and a generally disappointing performance in the stock itself.

Highlights from TheStreet Ratings analysis on LPTH go as follows:

  • Despite its growing revenue, the company underperformed as compared with the industry average of 9.2%. Since the same quarter one year prior, revenues slightly increased by 5.5%. This growth in revenue does not appear to have trickled down to the company's bottom line, displayed by a decline in earnings per share.
  • LPTH's debt-to-equity ratio is very low at 0.00 and is currently below that of the industry average, implying that there has been very successful management of debt levels. To add to this, LPTH has a quick ratio of 2.10, which demonstrates the ability of the company to cover short-term liquidity needs.
  • The gross profit margin for LIGHTPATH TECHNOLOGIES INC is rather high; currently it is at 52.55%. Regardless of LPTH's high profit margin, it has managed to decrease from the same period last year. Despite the mixed results of the gross profit margin, LPTH's net profit margin of -4.45% significantly underperformed when compared to the industry average.
  • 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 Electronic Equipment, Instruments & Components industry. The net income has significantly decreased by 161.8% when compared to the same quarter one year ago, falling from $0.22 million to -$0.13 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 Electronic Equipment, Instruments & Components industry and the overall market, LIGHTPATH TECHNOLOGIES INC's return on equity significantly trails that of both the industry average and the S&P 500.

TheStreet Ratings rates Aehr Test Systems as a sell. Among the areas we feel are negative, one of the most important has been weak operating cash flow.

Highlights from TheStreet Ratings analysis on AEHR go as follows:

  • Net operating cash flow has significantly decreased to -$0.60 million or 165.22% when compared to the same quarter last year. In addition, when comparing to the industry average, the firm's growth rate is much lower.
  • The company's current return on equity greatly increased when compared to its ROE from the same quarter one year prior. This is a signal of significant strength within the corporation. Compared to other companies in the Semiconductors & Semiconductor Equipment industry and the overall market, AEHR TEST SYSTEMS's return on equity significantly trails that of both the industry average and the S&P 500.
  • AEHR's debt-to-equity ratio is very low at 0.06 and is currently below that of the industry average, implying that there has been very successful management of debt levels. Although the company had a strong debt-to-equity ratio, its quick ratio of 0.96 is somewhat weak and could be cause for future problems.
  • The gross profit margin for AEHR TEST SYSTEMS is rather high; currently it is at 51.57%. It has increased significantly from the same period last year. Despite the strong results of the gross profit margin, AEHR's net profit margin of 3.77% significantly trails the industry average.
  • This stock has increased by 67.15% over the past year, outperforming the rise in the S&P 500 Index during the same period. Regarding the future course of this stock, we feel that the risks involved in investing in AEHR do not compensate for any future upside potential, despite the fact that it has seen nice gains over the past 12 months.

Currently there are no analysts who rate BTU International a buy, no analysts rate it a sell, and none rate it a hold.

TheStreet Ratings rates BTU International as a sell. The company's weaknesses can be seen in multiple areas, such as its disappointing return on equity and weak operating cash flow.

Highlights from TheStreet Ratings analysis on BTUI go as follows:

  • 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 Semiconductors & Semiconductor Equipment industry and the overall market, BTU INTERNATIONAL INC'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 -$2.70 million or 56.59% when compared to the same quarter last year. In addition, when comparing to the industry average, the firm's growth rate is much lower.
  • BTU INTERNATIONAL INC has improved earnings per share by 42.4% in the most recent quarter compared to the same quarter a year ago. This company has not demonstrated a clear trend in earnings over the past 2 years, making it difficult to accurately predict earnings for the coming year. During the past fiscal year, BTU INTERNATIONAL INC reported poor results of -$1.21 versus -$1.16 in the prior year.
  • Despite currently having a low debt-to-equity ratio of 0.44, it is higher than that of the industry average, inferring that management of debt levels may need to be evaluated further. Despite the fact that BTUI's debt-to-equity ratio is mixed in its results, the company's quick ratio of 1.72 is high and demonstrates strong liquidity.
  • 38.34% is the gross profit margin for BTU INTERNATIONAL INC which we consider to be strong. It has increased from the same quarter the previous year. Regardless of the strong results of the gross profit margin, the net profit margin of -15.28% is in-line with the industry average.
