By Craig Bonthron, fund manager in Artemis’ impact equities team.

I’m a big fan of Michael Mauboussin. He’s a leading investment thinker and the various threads of his research are woven through our investment process. I recommend reading Expectations Investing and I particularly like his lecture on “the paradox of skill”. My favourite piece of his research, however, is a short paper with a long title: Dispersion and Alpha Conversion: How Dispersion Creates the Opportunity to Express Skill

Dispersion of returns creates opportunities

Research suggests that the higher the dispersion of returns within a particular asset class, the more likely it is that fund managers will be able to use their skill to differentiate themselves. This is one reason why we chose to focus our efforts on small-cap and mid-cap equities: it is the part of the global equity market where the dispersion of returns is the highest. (The other reason is that smaller companies have more impact).

Higher dispersion allows for enhanced expression of skill across asset classes

Within a given market, the level of dispersion varies by subsector. Returns in some parts of the market (such as utilities, banks and energy) are relatively homogenous because macro factors (inflation, bond yields and energy prices) have a dominant influence. Returns in some other sectors, however, are highly dispersed because stock-specific factors are the predominant driver. Areas where dispersion is higher than average include software, retail and healthcare

Bubbles (and the bursting of bubbles) temporarily leads to high correlations in asset prices

Unfortunately, the dispersion of returns is not consistent through time. Most notably, correlations can become very high when asset-price bubbles are inflating and when they are bursting. Because a macro factor (irrational exuberance; irrational despair) temporarily overwhelms the micro drivers, we see high levels of market inefficiency. These conditions are the short-term enemy of stockpickers – particularly for investors who, like us, focus on small-caps and mid-caps. But over the long-term, temporarily high correlations can also be our friend…

Over the past year or so, ‘profitless growth’ has become a catch-all term used to describe low-quality SPACs and ‘growth-at-any-price’ investments – one synonymous with the most dangerous parts of the market. The following chart shows that the correlation of returns between large-cap, lossmaking growth stocks is at a 32-year high. Valuation multiples of this group of stocks, meanwhile, have fallen to historic lows. The price-to-sales ratio of this group is now 1.47x versus an historic average of 3.8x (a 60% discount) and compared to a 2021 high of 5.4x (a 73% decline).

We currently own three companies that fall into the category of ‘lossmaking growth stock’ but we have strong conviction that their continuing investments in their future growth (rather than sacrificing growth to produce cashflows in the short term) is the correct course.

High correlations and low valuation multiples signal opportunity

The excesses of the 2021 liquidity-driven SPAC bubble are behind us. Now that the tide has gone out, we are beginning to see which growth companies were skinny-dipping; many weren’t, but the assumption the market seems to be making is that every high-growth stock left its swimming costume at home.

The result is that correlations are unusually high and valuations are historically low. To us, this is a clear signal that – over a sensible investment horizon – we are likely to see high rates of future return. So we fully expect that what may seem like our enemy in the short-term will be our fond friend over the long term.
