SME (also known as Small and Medium-sized Enterprise) is a term used to classify businesses based on their size, typically measured by the number of employees and financial metrics like annual turnover or the total value of assets on their balance sheet. These businesses are the unsung heroes and the backbone of most modern economies, creating jobs and driving innovation far from the limelight of giant multinational corporations. While the concept is universal, the exact definition of an SME can be a bit of a moving target, varying significantly from one country or organization to another. For an investor, understanding SMEs is crucial because they represent a vast and often overlooked universe of potential investment opportunities. They are the acorns from which mighty oaks can grow, but they also face a unique set of challenges compared to their larger, more established counterparts.
Pinning down a single, global definition for an SME is like trying to nail jelly to a wall. The thresholds are different depending on where you are. The two most influential definitions for European and American investors come from the European Union and the U.S. government.
The EU has a very clear and widely adopted definition that breaks SMEs down into three categories. To qualify, a company must meet criteria for both staff headcount and either turnover or balance sheet total.
Across the pond, the U.S. Small Business Administration (SBA) takes a more tailored approach. Instead of a one-size-fits-all financial threshold, the SBA often defines a small business based on its industry. Size standards are usually stated as either the average number of employees over the past 12 months or the average annual receipts over the past three years. For example, a company in the manufacturing sector might be considered small with up to 500 employees, while a travel agency might have a revenue-based cap of $22 million in annual receipts. This complexity means you have to do a little more homework to see if a U.S. company officially qualifies as “small.”
For followers of value investing, the world of SMEs can feel like a treasure hunt. While large, famous companies are scrutinized by thousands of analysts, many SMEs operate just below Wall Street's radar.
Of course, it's not all smooth sailing. Investing in SMEs comes with its own set of significant risks.
For the ordinary investor, there are a few common pathways to gain exposure to SMEs.
