How Inflation Affects Companies and Stocks

A company reports sales up 20% in a year. Good news? That depends on how much prices rose across the economy in the same year. Inflation makes the numbers bigger without the business necessarily growing.

What you will learn

  • Tell nominal growth from real growth in a company's figures.
  • See why one company copes with inflation while another is squeezed.
In this lesson

Nominal and real

Inflation means prices across the economy are rising in general, so a pound buys less than before. Any figure in pounds in a company report, such as sales or profit, is a "nominal" figure. To know whether the business really grew, compare its growth with inflation over the same period. That comparison is "real" growth.

Sales growth (nominal)+20%
Prices across the economy+25%
Sales in real terms, roughly−4%
Sales rose in pounds, but if prices rose more, sales in real terms may have shrunk.
An invented exampleAn invented company, Oasis Detergents, grew sales from EGP 500 million to 600 million, up 20%. If prices across the economy rose 25% that year, the 600 million is worth only about 480 million at last year's prices (600 ÷ 1.25). So its sales are roughly 4% lower in real terms, even though the number grew. This is a rough adjustment using general inflation; knowing how much the company actually sold needs its own volume and price data.

Who copes with inflation better?

Inflation hits a company from two sides: its costs rise, such as materials, wages and shipping, while it tries to raise its own prices. The outcome depends on one question: can the company raise prices as fast as its costs rise without losing customers? That ability is called pricing power.

Same inflation, different marginsA company sells a product for EGP 100 that costs 70 to make, keeping 30. Costs rise 30% to 91. If it can raise its price 30% to 130, it keeps 39. If the market only accepts 15% and the price becomes 115, it keeps just 24. Same inflation, opposite outcomes.

No sector wins or loses from inflation as a whole. Pricing power differs from company to company, depending on competition, on whether the product is essential or easy to give up, and on whether some prices are set by others.

Reading figures in inflationary times

Compare sales and profit growth with inflation, not with zero. Watch the profit margin year to year: a shrinking margin can be a sign that costs are outrunning prices, though it can have other causes too, so look for the reason in the company report. The central bank uses interest rates to try to cool inflation, so the two stories are usually read together.

Watch outA higher profit in pounds does not mean the company got better, or that its share must rise. The market may value it higher or lower depending on how it reads its real growth and its margin.

Look at company figures

Open any company's results and compare its sales growth with inflation over the same period.

Check yourself

1. A company's sales grew 10% while prices rose 15% that year. What is its real growth, roughly?

Sales grew less than prices, so sales fell in real terms.

2. What helps a company cope with inflation better than others?

Pricing power is what protects the margin.

Summary

  • Inflation inflates nominal figures, so compare a company's growth with inflation, not with zero.
  • The ability to raise prices along with costs protects the profit margin.
  • No sector wins from inflation as a whole; the effect differs by company.
