Do these ratio values and ratios look strong, weak or in between?

Ratio values cannot be judged in isolation.  For example, the Phone Corporation's ratios calculated previously have no industry benchmarks against which they can be compared.  The ratios for competitor can also be used for comparison.  Again, the ratios were calculated for only one period in each case.  There should be a trend analysis and computation of ratios over some years in order to assess their strengths and weaknesses.

Overall, they do not look strong.  But, one should not be too quick to conclude on this issue.

Explanation:

Ratio analysis is a technical method of gaining insight into a company's liquidity, operational efficiency, and profitability by comparing the elements of its financial statements such as the balance sheet and income statement.  While ratio analysis is a cornerstone of fundamental equity analysis, it must be noted that the values produced are just relative measures which cannot be meaningful without being related to some benchmarks or compared over a number of years.
