Finally, ratio analysis enables a firm to take the time dimension into account. In other words, whether the financial position of a firm is improving or deteriorating over the years. This is made possible by the use of trend analysis. The significance of a trend analysis of ratios lies in the fact that the analysts can know the direction of movement, that is whether the movement is favorable or unfavorable. For example, the ratio may below as compared to the norm but the trend may be upward. On the other hand, though the present level may be satisfactory but the trend may be a declining one.
