Opportunity: Value investing

The beauty of small and mid caps

Bigger is not always better: some of the best opportunities can be found in mid-cap and small-cap stocks. Our value investing strategies offer the opportunity to tap into this vibrant and diverse corner of the equity market.


Why mid caps and small caps?

Most of the growth in a developed economy is driven from the bottom up, led by smaller companies at the cutting edge of new trends and products. Don’t forget that Microsoft and Apple were once start-ups.

Using Russell’s definitions, mid-cap companies start at USD 7 billion in market value and go up to USD 52 billion. These companies are well established, with strong track records, so they typically do not face bankruptcy risk, and can offer considerable growth opportunities.

Why now?

Mid caps and small caps tend to be more highly leveraged, with higher relative debt levels than large caps. This means they benefit more from an environment in which interest rates are cut, lowering interest payments and boosting profits. As rates are likely to have peaked on both sides of the Atlantic, this is the environment we are witnessing today.

The domestic focus of President Trump is also expected to benefit mid caps, where over 80% of revenues are generated domestically, thus avoiding any future tariffs. As Trump’s policies also point to a higher-for-longer inflationary and rates environment, the value style would also benefit.

Taken together, mid caps and small caps have generally outperformed other stocks once central banks begin their easing cycle, and emerged better from downturns, as the charts below show.

A time-tested approach

Boston Partners uses the tried and tested ‘three circles’ philosophy to find the best stocks across all capitalization sizes. A company must have good fundamentals, strong business momentum, and a valuation that allows for upside, to be eligible for inclusion in portfolios.

Research driven

Research driven

A quantitative screen ranks the universe of names across valuation, fundamentals and momentum, using metrics that have been back tested to ensure true representation of the desired metric. Fundamental analysts then conduct bottom-up research on each company.

Sustainability integration

Sustainability integration

As a pioneer of sustainable investing since the 1990s, the integration of environmental, social and governance (ESG) factors, plus the use of engagement, is standard practice. The UCITs strategies are both classified as Article 8 under the SFDR.
