Why One Financial Ratio Is Insufficient in Financial Analysis

One Ratio Measures Only One Aspect of Performance

An analyst can calculate liquidity, profitability, solvency and leverage ratios (in isolation) for a given company at a given time. All financial ratios have limitations, especially liquidity ratios.Liquidity ratios are used to measure the amount of cash in a company at a given time period to cover current liabilities, so they do not depend on the length of time until those liabilities must be paid off..by way of explanation, liquidity ratios do not tell us whether the company will continue to be profitable if cash is removed from circulation; therefore, if we focus our analysis of a business solely based on liquidity, we do not take into consideration that the company may not earn enough profit to qualify as 'profitable.'

Conflicting Signals from Different Ratios

Different ratios yield contradictory messages. By using financial ratios to assess the performance of businesses, each ratio conveys a unique perspective on business performance. The financial ratios examine specific areas of a business' operations thereby the ratio reflects an assessment of those operations within the context of the area being studied. Therefore, when evaluating financial ratios one may initially appear to provide a positive evaluation; however, when multiple ratios are evaluated together they may illustrate a situation within the business that cannot be determined through the assessment of a single financial ratio.

As an illustration, a company may exhibit a high return on equity ratio as being a good indicator of efficient use of stockholders' capital. Conversely, the same company may display a very high debt to equity ratio. Therefore, it is possible that the company's high return on equity ratio results from the use of high levels of debt for financing rather than high levels of operational performance. As a result, while the company does exhibit a high return on equity, they also reflect increased financial risk due to their high levels of debt.

Thus, if an analyst solely relied upon the return on equity ratio to measure the financial performance of the company, they could possibly misinterpret other significant elements of the company's business.

Industry Differences and Their Impact on Ratios

Financial ratios vary in their importance across several different industries. Each industry has different operating costs, capital requirements, and economic cycles that cause the ways in which an industry utilises these ratios to differ from one another. Therefore there can be instances where certain ratios may look good in one industry but appear to be unfavourable or high-risk in another industry; therefore, it is critical to understand the industry context when looking at a specific ratio.

Manufacturers are normally considered to be heavily capitalised and generally depend on inventory and machinery as their main source of revenue. Due to their capital-intensive nature, manufacturers may also carry a relatively high level of debt. As such, when looking at the debt-to-equity ratio for a manufacturer, you should expect that the ratio will generally be higher for a manufacturer than other types of companies. On the other hand, service-based companies typically have lower capital requirements and therefore can fund their operations with little or no debt. Thus, comparing the debt/equity ratios between manufacturers and service-based businesses without considering industry characteristics could result in erroneous conclusions.

Retail businesses also represent a suitable example. Retail businesses usually operate with a lower current ratio than service or manufacturer businesses due to the speed of their inventory turnover.

Effect of Business Size and Scale on Ratios

The size and/or scale of businesses cannot be measured using financial ratios alone. The financial strength and market positions of two businesses may differ greatly, even when their respective financial ratios appear comparable to each other.

As an example, assume the net profit margin of both companies is 10%. The first business generates revenues of Rs. 10 crore, while the second generates only Rs. 10,000 crore. Although both businesses have a 10% net profit margin, the second company is in a better position as it has access to more resources and can bear greater risk.

Likewise, the small company may show growth in terms of its low revenue, while the large business may have a high revenue and thus fell slower. If only one financial ratio is used as a means of determining a business' level of performance, the reality of the business's financial position could go unnoticed by analysts.

In addition, the size of the business impacts its ability to access financing, have a strong negotiating position, and maintain operational stability. Ratios do not account for these differences. Therefore, in evaluating a business, absolute financial data and consideration of the scale of the business must be part of the analysis.

Thus, simply using one financial ratio will not give a clear picture of the overall performance of a business.

Ratios Are Based on Historical Information

Financial ratios are based on past financial information, so reflect only what a business has already done and does not predict what it will do in the future. Also, as business conditions continuously evolve, to depend on one ratio from one time may be very misleading.

Many times a profit ratio for a specific year may appear very strong due to a unique item being recorded that year, such as the sale of an asset or the occurrence of a large gain. As a result, profit figures for that specific year may look very good; however, this one time event does not guarantee the same type of results will recur in following years. Thus, an analyst focusing on this ratio only, may miss or misinterpret the long-term earning potential of a business.

Furthermore, as there are economic, competitive, and political impacts on financial performance in the future (i.e., losses or decreases in gross sales), those influences cannot be quantified through the use of a ratio. Additionally, there is no direct correlation of how a performance ratio changes for an entire company, based on years of performance.

The best way to mitigate these limitations of a ratio would be to conduct an analysis of the same ratios over a number of consecutive years; therefore identifying trends as opposed to "one-shot" situations. In conclusion, the ratio from any particular year is not a true representation of the financial status or picture of a business.

Effect of Accounting Policies on Financial Ratios

Both the financial ratios and how they are derived are directly influenced by both the accounting policies employed by the firms reporting the financial ratios and the industry within which each firm operates, and because there are no uniform accounting practices or accounting policies across the same industry, financial statements from different companies may not provide a comparable basis between the companies reporting those financial statements. Therefore, relying exclusively on one ratio when analyzing a corporation's financial performance is misleading without an understanding of the accounting policies that created that ratio.

For example, there are various methods for depreciating assets (e.g. straight-line method or the written-down value method), and these different methods will create differing amounts of depreciation expense, which will in turn derive different profit levels, and therefore affect profitability ratios (e.g. net profit margin or return on assets). Similarly, there are also various methods of valuing inventories (e.g. FIFO or weighted average) which will result in different costs of goods sold and ending inventories, which will also affect gross profit ratios.

Likewise, revenue recognition policies also impact how profits are recognised and reported. The timing of when revenue is recognised can vary widely between companies; one company may recognise revenue sooner than another company, or if both companies use a more conservative approach, they both may have similar revenue amounts at the same time when finalised, but one company may have a greater profit due to utilising a different revenue recognition policy.

Financial ratios cannot be compared between firms with different types of accounting policies. Therefore, it is necessary to interpret financial ratios in conjunction with the accounting policies used by the firm reporting the ratio instead of relying solely on one ratio.

Profit Does Not Always Mean Cash Flow

Although many financial ratios emphasize the profitability figures of businesses, this does not necessarily represent their cash position. For instance, a business can have a high enough profit, but also be experiencing considerable cash-flow issues. Profits are calculated using accrual accounting, which reflects profit earned (on credit) but not actually received in cash; rather than actual movement of cash represents cash flow.

In other words, a company can demonstrate strong sales and above average sales margins, but even if a majority of those sales are made using credit, this could result in not getting paid as quickly as anticipated. As such, regardless of how profitable a company looks on paper, they may not have enough cash to pay employees, suppliers or make loan payments, thus indicating profitability ratios alone are not sufficient to measure the financial health of a company.

Cash flow from operating activities provides the best measurement for the ability of companies to operate on a day-to-day basis. The combination of liquidity ratios and cash flow analysis must be used together with profitability ratios to see and understand the complete financial position of a company.

To rely on one profit-based financial ratio without considering one's cash flow, simply overlooks the importance of cash management within companies. Therefore, even a business that is highly profitable may run into trouble without having adequate cash flow. Consequently, this demonstrates that one financial ratio does not tell the entire financial story of a company.

One Ratio Cannot Measure Business Risk

Financial ratios are useful tools for evaluating specific risks associated with a company. Financial risk is just one portion of the total exposure of an organisation. Many other factors contribute to total exposure including financial leverage (debt), competition, and government or regulatory changes, as well as economic changes over time. A single financial ratio does not adequately provide insight into all of these elements of financial risk.

A business with a low debt-to-equity ratio indicates lower risk potential from a financial viewpoint. An approach to analysing the risk profile of a business requires a more in-depth evaluation of other variables such as industry competitiveness, regulatory requirements, technological advances, and changing market conditions over time, in conjunction with multiple financial ratio analyses.

For example, while net profit margin indicates strong profitability, an extended dependence on only one product or customer creates a concentration risk that does not appear within the financial ratio system. Likewise, external influences from the economy (such as increased interest rates) and changes in federal policies can have a tremendous impact on profitability but are not necessarily reflected through the financial ratios.

Lastly, although multiple financial ratios can give a good overview of certain areas of potential risk, they are not comprehensive measures of total risk. Hence, the need for both quantitative and qualitative ways to assess total risk, including the need for multiple financial ratios instead of one ratio that may not adequately indicate how to assess total risk.

Window Dressing and Manipulation of Ratios

Window dressing is a common accounting strategy used by businesses to create artificially high levels of financial ratios. This is accomplished through the manipulation of temporal data, which gives a business better ratios at the end of an accounting cycle than it has actually achieved. While the financial ratios appear to show improved economic viability for the business, they do not reflect an increase in the actual working capital and will generally not reflect on-going revenue-producing capacity of the business.

One way to "window dress" a company is to pay off its short-term liabilities at the end of the fiscal year (FY). By doing this, the company increases its ratio of current assets to current liabilities, increasing its liquidity. Another method is the postponement of all maintenance and promotional activity (so as to have no rupee expenditure against sales revenue at the end of FY). The end result is that the financial ratio of profitability and liquidity of the company has been increased, but the company's operational efficiency has suffered.

The use of one ratio to evaluate the financial performance of a company for a limited set of time could mislead the valuer as the valuer may not take into account any temporary improvements created by the management. Analysing financial ratios over a progressive period of time, in conjunction with a review of cash flow statements, will enable analysts to begin to form a well-rounded opinion of an organisation's financial situation.

Importance of Using Multiple Ratios Together

To assess how well a business performs financially, it cannot just rely on a few financial ratio values individually and instead combine many kinds of financial ratios into one overall analysis of how good the company has been able to perform, as it gives investors an accurate representation of what happened and allows them to make more informed investments. The multiple kinds of financial ratios are based on the basis that they are used to help understand the functionality of a business from a number of different perspectives: liquidity represents the company's ability to cover its short-term debts; profitability is an indication of the company's ability to generate income; solvency (next level of loan repayment) shows the soundness of the company over the long term; efficiency looks at how well a company has maximized its assets.

If investors only analyze one financial ratio, they will be left with an inadequate picture of both the strength and weaknesses of investing in that company and potentially make investment decisions based on incorrect information. By combining all the various kinds of ratios together, investors will hopefully have enough understanding of the ratios' relative values to give them an understanding of the relationship between each ratio's strength and weaknesses, which will allow them to make informed decisions regarding investment in and management of that business.

conclusion

While financial ratios provide insight into the financial performance of a business, they are not without limitations. A financial ratio is simply a measure of one aspect of a business; therefore, one financial ratio cannot portray a complete picture of a business's financial performance. The excessive reliance on only one financial ratio may create misleading interpretations due to the omission of other key elements that play a major role in a business's financial performance, including the following: liquidity, profitability, efficiency, solvency, and cash flow.

In addition, financial ratios are also subject to industry differences, company size, accounting policy difference, and temporary factors or events. Conversely, factors such as window dressing, trend analysis, and qualitative factors such as management abilities and industry competitive position also influence the way in which financial ratios are interpreted by analysts, investors, and management teams. Consequently, it is critical that analysts, investors, and management teams combine multiple financial ratios when evaluating a business, look at trends over time, and compare their businesses to their peers to obtain a better understanding of the business's financial performance.

To summarize, financial ratios are indicators of financial performance but are not a conclusive measure of a business's financial performance. Financial performance analyses must incorporate multiple financial ratios, context, and quality factors in order to accurately evaluate a business's performance and arrive at sound financial decisions. This is why a single financial ratio does not present the complete picture regarding a business's financial performance.
