INVESTOR LETTER #94
Volume Growth
Volume growth measures the increase in the number of products or services a company sells, independent of price changes. Learn why investors track volume growth to evaluate customer demand, market share gains, and the quality of revenue growth. Sustainable volume growth is often a stronger indicator of long-term business strength than revenue growth driven primarily by price increases.
INVESTOR NOTE
A business owner thinks in decades. A speculator thinks in minutes.
The Restaurant That Never Raises Prices
Imagine two restaurants. The first increases menu prices by 15% every year, but the number of customers stays the same. The second keeps prices unchanged, yet every month more people visit because the food is excellent and customers recommend it to friends. Which restaurant has stronger demand? Most investors would choose the second one. That's the power of volume growth.
What Is Volume Growth?
Volume growth refers to an increase in the number of units sold rather than the price charged. For a car company, it's more cars sold. For a cement company, it's more tonnes sold. For a beverage company, it's more bottles sold. It measures whether the business is attracting more customers or selling more to existing ones.
Revenue Can Be Misleading
A company may report 20% revenue growth, but that doesn't automatically mean the business is becoming stronger. Revenue can grow because prices increased, because more products were sold, or because of acquisitions. Without separating these factors, investors cannot understand what is actually driving growth.
Why Investors Love Volume Growth
Growing volumes usually indicate that customers genuinely like the company's products or services. It often reflects increasing market share, better distribution, stronger customer loyalty, or successful innovation. Unlike price increases, volume growth is difficult to fake over long periods.
When Volume Falls Despite Higher Revenue
Sometimes a company reports impressive revenue growth while unit sales actually decline. This often happens when prices rise sharply. If customers continue buying fewer products every year, management may eventually run out of pricing power. Investors should always examine both numbers together.
The Best Businesses Grow Both
The strongest businesses don't have to choose between price and volume. They steadily increase the number of customers while also raising prices from time to time. When both happen together, revenue and profits can compound much faster than either factor alone.
Market Share Often Tells the Story
A company can grow its volumes because the entire industry is expanding, or because it is taking customers away from competitors. The second type is usually more impressive because it suggests the business has a competitive advantage.
Temporary Volume Growth Isn't Enough
A single year of strong sales doesn't prove much. Promotional discounts, one-time government orders, or unusually high demand can temporarily boost volumes. Long-term investors look for consistent volume growth over many years rather than one exceptional quarter.
Different Industries Measure Volume Differently
Every industry has its own definition of volume. Airlines track passenger numbers, banks monitor loans and deposits, software companies measure subscribers, retailers count same-store sales, and hospitals may track patient visits. Understanding the right operating metric is essential for evaluating business growth.
Where to Find Volume Data
Many companies disclose volume growth in annual reports, quarterly presentations, conference calls, and investor fact sheets. Management often separates revenue growth into volume growth and price growth, giving investors a much clearer picture of business performance.
Price Growth vs. Volume Growth
Neither is inherently better. Young and expanding businesses often rely more on volume growth as they acquire new customers. Mature businesses with strong brands may rely more on pricing power. The truly exceptional companies manage to achieve both over long periods.
One Question Every Investor Should Ask
Whenever a company reports strong revenue growth, ask yourself: 'Did the company actually sell more products, or did it simply charge higher prices?' The answer often reveals whether the business is growing because customers genuinely love it—or simply because prices went up.
