Standard Industrial Classification (SIC) codes are an important tool for real estate investors to analyze industries and make informed investment decisions. SIC codes categorize companies by their primary business activity, providing insights into the performance and outlook of different real estate sectors. By studying SIC codes, investors can identify attractive industries with strong growth potential to focus their capital. This article explores how SIC codes work and their application in real estate investment analysis.

SIC codes provide a standardized system to classify industry sectors
SIC codes were developed by the US government to uniformly categorize business establishments by industry. Companies are assigned a 4-digit SIC code that describes their primary line of business. For example, real estate developers fall under SIC code 6531, real estate agents under SIC code 6531, and lessors of real estate under SIC code 6500. There are over 1000 SIC codes that cover the entire economy. By classifying companies into SIC groups, investors can analyze performance trends and growth drivers across different real estate sectors.
SIC code data enables comparison of financial ratios across industries
One of the key applications of SIC codes is comparing financial ratios across different industry groups. By looking at average metrics like revenue growth, profit margins and debt levels of all companies within a 4-digit SIC code, investors can gauge the relative valuation and risk of those sectors. For example, apartment REITs classified under SIC code 6798 will have different ratios compared to retail REITs under SIC code 6798 due to differences in their underlying property types. SIC code data allows investors to identify real estate sectors trading at attractive valuations.
SIC codes help assess demand drivers and growth outlooks for real estate sectors
Each real estate property type has unique demand drivers based on its end-users and macroeconomic forces. Analyzing SIC codes provides insights into key factors affecting the performance of each sector. For example, demand for industrial real estate in SIC code 42xx is driven largely by e-commerce growth, while SIC code 7011 hotels rely on business and leisure travel trends. Assessing growth projections for the end-markets categorized by SIC code provides investors a top-down view of real estate sectors with strong upside potential.
SIC classification is useful for competitive analysis within a real estate sector
When conducting due diligence on an individual real estate investment, SIC codes facilitate analysis of its competitive landscape. By looking at all the companies classified under the same 4-digit SIC code, an investor can assess factors like the number of competitors, market concentration and stability of market shares within that sector. This can highlight risks of increased competition or market disruption when underwriting a particular property or real estate company investment.
In summary, SIC codes are an invaluable tool for real estate investors to analyze sectors in a systematic way. By leveraging SIC code data, investors can identify attractive industries with favorable growth outlooks, assess relative valuations, and conduct competitive analysis to make informed investment decisions.
