Why UK small cap could be the stand-out performer of 2023

Following a gloomy 2022, 2023 has brought tentative reasons for optimism on the global economy. In particular, softening inflation and hopes that the recession may not be as severe as expected. Smaller companies have often performed well during periods of improving economic sentiment. Following a challenging year, is now the time to reconsider small cap stocks?

Key takeaways:

  • UK small and medium-sized companies struggled in 2022 as elevated inflation and higher interest rates amid a cost-of-living crisis heightened concerns about a deep and prolonged recession.
  • We see three reasons to invest in the small-cap space: current valuations provide an attractive entry point for investors, small caps tend to outperform following periods of underperformance, and a pick-up in M&A activity.
  • Our portfolio companies have robust balance sheets, are leaders in their field with a strong competitive advantage and have experienced management teams that can help them navigate a challenging environment.

Every cloud…

While 2022 was bad for almost all assets, it was particularly bad for smaller companies, with the Numis Smaller Companies Index (ex Investment Companies) down 17.9% all-told by the end of the year.1 The economic and investing environment has been dour for a number of reasons. First, high inflation and interest rates are curtailing the spending power of consumers. Prices for essential items such as food and clothing have become significantly more expensive, while higher mortgage rates have eaten into disposable income. Second, given that smaller companies tend to have more domestic consumer exposure, the cost-of-living crisis has been having a direct impact on revenues.

Slowing growth and uncertainty are never a good combination for smaller companies where operational risks are perceived to be more concentrated versus their large-cap peers. And it’s no surprise, that they have struggled in this market environment. However, we believe that the sell-off has become overstretched and too much gloom is being reflected in the prices of these assets.

What is more, we’re in the midst of a slowdown deliberately manufactured by central banks to deal with inflation, which is showing signs that it may be peaking. Indeed, if the inflationary picture starts to markedly improve over the coming months, Central Bankers might change tack or at the very least, not continue to hike base rates. Given this scenario, we believe there are three reasons investors should be looking to invest in small cap stocks.

1) Buying at low valuations is a good starting point for investors

Many a seasoned investor will see the opportunity to enter stock markets when they are depressed. In essence, there’s the potential to buy great assets at discount prices and given that you are starting from a low base, it can offer the opportunity for strong returns. The UK, in particular, is looking cheap when compared to other markets. For example, when we look at the 12-month forward P/E ratio, UK stocks are much cheaper relative to history and compared to global peers.

Note: Forward price-to-earnings (forward P/E) is a version of the ratio of price-to-earnings (P/E) that uses forecasted earnings for the P/E calculation. There is no guarantee that past trends will continue, or forecasts will be realised. The views are subject to change without notice.

Based on the recent sell-off, the market does not seem to be discerning between good and poor companies – meaning even high-quality companies have also been caught in the storm. While the performance of stocks over the short-term is largely driven by sentiment, over the long-term, valuations matter. To us, current valuations look attractive, potentially offering a great starting point to investors looking to invest in the space.

2) Small-caps tend to perform strongly following periods of bad performance

When assessing performance, context is very important, especially when dealing with smaller and medium-sized companies. While periods of short-term underperformance are obviously disappointing, it’s important to retain the longer-term view. If we look back through history, small caps have outperformed their larger-cap counterparts over the longer-term. In addition, following periods of underperformance – where the value of shares drop by more than 20% relative to large cap stocks – small caps tend to perform strongly afterwards. The Numis Smaller Companies Index (excluding investment companies) offers some evidence. Since the Second World War, the global economy has witnessed four global recessions. Though small cap stocks struggled during periods of high volatility, they bounced back stronger than their larger-cap counterparts and significantly outperformed them in the subsequent years (see below). Since smaller companies tend to be more economically sensitive, they tend bounce back more quickly and grow more rapidly as we come out of a downturn. Since no one can predict when the current downturn is going to end, we believe investors with a small cap risk tolerance should view the current environment as a potentially opportune time to consider small caps.

Past performance does not predict future return

3) M&A activity showing signs of picking up

Another factor to consider is activity within M&A. Takeovers are a strong source of returns in the smaller company space, and the outlook for mergers & acquisitions (M&A) has begun to improve as buyers accept that corporate financing costs are likely to be higher for years to come. UK Plc is looking the most attractive it has in years, it is still sitting at a 40% discount to global peers, low not seen in 40 years, and company valuations remain cheap. What is more, following the wave of recapitalisations undertaken by corporates during the pandemic, company balance sheets are in a good shape. In addition, a calmer political backdrop in the UK may reduce risks in dealmaking. A big potential candidate for takeovers is private equity where they retain a lot of ‘dry powder’ – cash waiting in the wings to be deployed. Given the weak pound, particularly against the dollar, the purchasing power of other currencies to buy into firms increases the attractiveness of deals.

Making the most of the opportunity

Macroeconomic uncertainty remains at elevated levels. Tight labour markets may render inflation sticker than the market is forecasting, which curtails the chances of a pause in interest rate rises. However, the flight to safety in 2022 led to an indiscriminate sell-off stocks in the small and mid-cap space. We believe the consequent attractive valuations on offer in that part of the market in conjunction with low investor sentiment provide a good entry point for investors.

Within the portfolio, we are focused on investing in high quality companies in the small and mid-cap space that should have the means to survive a downturn if it materialises and thrive once it abates. Our investment process should yield a portfolio of companies that have enduring franchises, strong competitive advantages, experienced management teams that can navigate complex environments, and robust balance sheets. In fact, over half of the portfolio value has balance sheets with net cash. Selectivity and good stock picking will be crucial as the strength of the franchises, their market positioning, and the health of their financials will likely determine the winners from the losers. For the long-term investor, it seems now is an opportune moment to invest in the UK’s smaller innovative firms that have the potential to grow far faster than their larger counterparts and deliver strong long-term returns.

    Specific risks
  • If a Company's portfolio is concentrated towards a particular country or geographical region, the investment carries greater risk than a portfolio that is diversified across more countries.
  • Most of the investments in this portfolio are in smaller companies shares. They may be more difficult to buy and sell, and their share prices may fluctuate more than those of larger companies.
  • This Company is suitable to be used as one component of several within a diversified investment portfolio. Investors should consider carefully the proportion of their portfolio invested in this Company.
  • Active management techniques that have worked well in normal market conditions could prove ineffective or negative for performance at other times.
  • The Company could lose money if a counterparty with which it trades becomes unwilling or unable to meet its obligations to the Company.
  • Shares can lose value rapidly, and typically involve higher risks than bonds or money market instruments. The value of your investment may fall as a result.
  • The return on your investment is directly related to the prevailing market price of the Company's shares, which will trade at a varying discount (or premium) relative to the value of the underlying assets of the Company. As a result, losses (or gains) may be higher or lower than those of the Company's assets.
  • The Company may use gearing (borrowing to invest) as part of its investment strategy. If the Company utilises its ability to gear, the profits and losses incurred by the Company can be greater than those of a Company that does not use gearing.
  • Using derivatives exposes the Company to risks different from - and potentially greater than - the risks associated with investing directly in securities. It may therefore result in additional loss, which could be significantly greater than the cost of the derivative.
