Financial Ratios

Introduction to financial ratios

What are financial ratios? 

Financial ratios are indicators of a company’s or industry’s performance. Comparing financial ratios at the company and industry level allows companies themselves to evaluate their own performance against peers and external parties to evaluate financial health from a risk perspective. Ratios can be used to benchmark present against past performance but also as a predictor of likely future performance.  

Investopedia defines ratios analysis as “a quantitative method of gaining insight into a company's liquidity, operational efficiency, and profitability by studying its financial statements such as the balance sheet and income statement.”

Some examples of popular ratios are:

Profitability – with ratios related to profit margins, return on assets and more.

Liquidity – including working capital, quick ratio, and more

Efficiency – including inventory turnover, turnover ratio and more

Financial ratios and industry codes

Industry codes

Familiarity with industry codes can help you find financial ratios. Industry codes are numerical systems used to classify companies, organizations and traders into groupings based on how they operate.

The most popular classifications used in North America are NAICS and SIC codes. Some publishers may also create their own classification. Please note that not all resources allow searching by industry codes.

NAICS codes North American Industry Classification System

NAICS is a 2- through 6-digit hierarchical classification system. Each digit in the code is part of a series of progressively narrower categories. The first two digits designate the economic sector, the third digit designates the subsector, the fourth digit designates the industry group, the fifth digit designates the NAICS industry, and the sixth digit designates the national industry.  

This standard is used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. NAICS is an industry classification system, not a product classification system.

SIC codes - Standard Industrial Classification

SIC codes are four-digit numerical codes assigned by the U.S. government to business establishments to identify the primary business of the establishment.

US Department of Labor SIC Manual includes short descriptions and examples of main products or services. SIC search – allows you to quickly identify relevant codes by performing keyword searches.

SIC is gradually being replaced by NAICS but many resources allow searching by both.
