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 AeroCentury as a sell. The company's weaknesses can be seen in multiple areas, such as its deteriorating net income, generally high debt management risk, disappointing return on equity, poor profit margins and weak operating cash flow.

Highlights from TheStreet Ratings analysis on ACY 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 Trading Companies & Distributors industry. The net income has significantly decreased by 305.1% when compared to the same quarter one year ago, falling from $4.02 million to -$8.25 million.
  • The debt-to-equity ratio is very high at 3.15 and currently higher than the industry average, implying increased risk associated with the management of debt levels within the company.
  • 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 Trading Companies & Distributors industry and the overall market, AEROCENTURY CORP's return on equity significantly trails that of both the industry average and the S&P 500.
  • The gross profit margin for AEROCENTURY CORP is currently extremely low, coming in at 6.25%. It has decreased significantly from the same period last year. Along with this, the net profit margin of -171.27% is significantly below that of the industry average.
  • Net operating cash flow has significantly decreased to -$1.55 million or 185.47% when compared to the same quarter last year. In addition, when comparing to the industry average, the firm's growth rate is much lower.

Spar Group ( SGRP) was another company that pushed the Diversified Services industry higher today. Spar Group was up $0.07 (5.0%) to $1.48 on heavy volume. Throughout the day, 16,480 shares of Spar Group exchanged hands as compared to its average daily volume of 6,100 shares. The stock ranged in a price between $1.41-$1.60 after having opened the day at $1.41 as compared to the previous trading day's close of $1.41.

SPAR Group Inc., together with its subsidiaries, provides merchandising and other marketing services worldwide. Spar Group has a market cap of $30.0 million and is part of the services sector. Shares are up 0.7% year-to-date as of the close of trading on Friday. Currently there are no analysts who rate Spar Group a buy, no analysts rate it a sell, and none rate it a hold.

TheStreet Ratings rates Spar Group 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 notable return on equity. However, as a counter to these strengths, we also find weaknesses including poor profit margins and a generally disappointing performance in the stock itself.

Highlights from TheStreet Ratings analysis on SGRP go as follows:

  • SGRP's revenue growth has slightly outpaced the industry average of 8.7%. Since the same quarter one year prior, revenues rose by 11.7%. This growth in revenue does not appear to have trickled down to the company's bottom line, displaying stagnant earnings per share.
  • SGRP's debt-to-equity ratio is very low at 0.28 and is currently below that of the industry average, implying that there has been very successful management of debt levels. To add to this, SGRP has a quick ratio of 2.02, which demonstrates the ability of the company to cover short-term liquidity needs.
  • SPAR GROUP INC reported flat earnings per share in the most recent quarter. 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, SPAR GROUP INC increased its bottom line by earning $0.15 versus $0.13 in the prior year.
  • SGRP's stock share price has done very poorly compared to where it was a year ago: Despite any rallies, the net result is that it is down by 27.37%, which is also worse than the performance of the S&P 500 Index. Turning toward the future, the fact that the stock has come down in price over the past year should not necessarily be interpreted as a negative; it could be one of the factors that may help make the stock attractive down the road. Right now, however, we believe that it is too soon to buy.
  • The gross profit margin for SPAR GROUP INC is rather low; currently it is at 23.56%. Regardless of SGRP's low profit margin, it has managed to increase from the same period last year. Despite the mixed results of the gross profit margin, SGRP's net profit margin of 1.23% is significantly lower than the industry average.
