And what about the future? Given the gloomy backdrop, investors are likely to avoid smaller companies for much of 2023. On the surface, this decision seems understandable. History shows that smaller companies tend to underperform larger ones during economic downturns. But dig a little deeper and a surprising conclusion presents itself: the time to start allocating capital to small caps might be sooner than investors think.

Small caps outperform earlier than expected

There are widely agreed assumptions about the performance of smaller and larger companies in different economic scenarios. Chart 1 shows the relative average performance of US small caps versus large caps, before, during and after recessions (dating back to the 1980s). Of course, each recession is different, with different mechanisms at play. Nonetheless, three factors stand out.

Firstly, larger companies tend to outperform their smaller rivals before, and at the start of, recessions. This makes sense. In economic slumps, risk-averse investors typically favour safer assets. In the equities space, this means more mature, well-established larger companies. Their markets are often less volatile and earnings more stable. By contrast, investors view smaller companies as riskier investments. Many businesses aren’t as entrenched as bigger firms. Earnings and profit margins can therefore come under pressure in times of upheaval.

Secondly, these factors are turned on their head when we exit a recession. In recovery periods, smaller companies usually outperform their larger rivals. By their very nature, small caps are nimbler and able to react faster than large caps to changes in the business environment. Smaller firms can therefore take advantage of the new opportunities a growing economy offers. The consequent rise in investor risk appetite also helps smaller companies.

So far, so predictable. But the third point is not widely known: smaller companies have historically started outperforming large caps soon after a recession starts. As you can see from Chart 1, this rebound can begin as early as three-to-six months into a recession. That’s because the market tends to price in an economic recovery before it happens. Yet this phenomenon is not part of the traditional small/large-cap narrative. We believe this disconnect creates opportunities for active investors.

A potentially attractive entry point

Smaller companies trailed their larger peers in 2022. In Europe, it was the worst relative year since comparative data began (see Chart 2). This has had a knock-on effect on valuations. Historically, European smaller companies have traded at an average premium valuation of 21%¹ above that of larger peers, thanks to superior small cap growth and earnings potential. However, at the close of last year, this difference dropped significantly and is currently at 9%. Given the potential rebound as we exit recession, this could represent an attractive entry point for long-term investors.

A similar dynamic is at play in the US. Here, the valuation discount of small caps relative to large caps is as wide as it has been in more than 40 years (Chart 3). We believe this creates excellent long-term opportunities. Indeed, after US small caps reached a similar level of ‘cheapness’ in early 2001, small-cap stocks materially outperformed larger caps over the subsequent three-, five- and 10-year periods¹.

What about today’s high inflation, high interest-rate environment?

As we highlighted, every downturn has its own characteristics – and this time is no different. Today, elevated inflation is a major factor (although it remains benign in much of Asia). Developed market central banks have responded by aggressively hiking rates. The medicine appears to be working. Eurozone and US inflation has retreated from summer highs, recording 9.2% and 6.5% in December, respectively¹. Nonetheless, it will take time for inflation to reach pre-pandemic levels.

But we believe high inflation shouldn’t worry small-cap investors too much. Many smaller companies operate in niche industries or areas of the market with few players. They’re also often a critical link in complex supply chains or wider manufacturing processes. As a result, they can dictate higher prices despite their size, allowing them to pass on costs to protect their margins. They also have the agility to change where they source goods and materials, further helping to control costs.

What about elevated interest rates? Many assume that higher rates hurt small caps more than larger caps. That’s because many small caps are starting out and have weaker balance sheets and lower profit margins. This is the case for some businesses. However, as anyone watching the headlines knows, several larger companies have also been found wanting in the world of higher interest rates. In short, durability frequently comes down to the quality of the company.

The importance of quality

That’s why we focus on high-quality firms, irrespective of the macroeconomic backdrop. That is, those with low leverage, strong profitability and consistent earnings. True, quality has underperformed in 2022 as many investors rotated into value stocks. But with the economy deteriorating, we believe investors will increasingly favour companies with robust business models, pricing power, healthy balance sheets and unique growth drivers.

Final thoughts…

So is now a good time to start considering smaller companies? The traditional answer would be a resounding ‘no’. The world economy is forecast to slow further in 2023, with a recession possible in the first half of the year. However, as we have shown, smaller companies might be more resilient in the current inflationary climate than many assume. Using history as a guide, we can also see that smaller companies start to rebound quicker during economic downturns than is widely assumed. With valuations depressed, investors could therefore potentially pick up great long-term opportunities at a discount.
