As the FTSE 100 index in the United Kingdom continues to hover around 7,000 points, a surprising trend has emerged: small-cap stocks are outpacing their larger counterparts, with some UK-listed small-cap stocks delivering returns as high as 30% this year. This phenomenon is not unique to the UK market; across the globe, small-cap stocks have been crushing their S&P 500 counterparts. The Vanguard FTSE UK Small-Cap Index Fund, for example, has outperformed its FTSE 100 counterpart by a staggering 25% over the past 12 months. This remarkable performance has many investors wondering: what’s behind this surge, and how can we tap into it?

One key driver of this trend is the UK’s thriving startup ecosystem. The country is home to a plethora of innovative companies, from fintech disruptors like Revolut to e-commerce upstarts like Deliveroo. These companies are not only creating new products and services but also disrupting traditional industries and creating new markets. Take, for example, the case of growth-hacking pioneer, Zapp, which has been instrumental in revolutionizing the UK’s food delivery landscape. Founded in 2014 by entrepreneur Ido Segev, Zapp’s innovative platform has enabled consumers to order food directly from restaurants, eliminating the need for intermediaries. Today, Zapp is one of the leading food delivery platforms in the UK, with a valuation of over £1 billion.

Another key factor driving the outperformance of small-cap stocks is the UK’s venture capital scene. According to a recent report by investment bank, Goldman Sachs, the UK has seen a significant increase in venture capital investments over the past few years, with many startup founders raising millions of pounds to fuel their growth ambitions. This influx of capital has enabled small-cap companies to scale quickly and aggressively, often leading to rapid returns for investors. Take, for example, the case of AI-powered software company, Darktrace, which has seen its valuation soar to over £1.5 billion after raising significant funding from venture capital investors. Founded in 2013 by former Cambridge University researcher, Poppy Gustafsson, Darktrace’s innovative platform uses machine learning algorithms to detect and prevent cyber threats.

The Full Picture

To understand the full picture, it’s essential to delve into the numbers. According to data from Bloomberg, the Vanguard FTSE UK Small-Cap Index Fund has outperformed the FTSE 100 index by a staggering 25% over the past 12 months, making it one of the top-performing small-cap funds globally. Similarly, the iShares UK Small Cap ETF has delivered returns of over 20% this year, outpacing its FTSE 100 counterpart by a significant margin. These numbers are all the more remarkable given the UK’s economic backdrop, which has been marked by Brexit uncertainty and sluggish economic growth.

But what’s driving this outperformance? Analysts point to a combination of factors, including the UK’s thriving startup ecosystem, the influx of venture capital investments, and the resilience of small-cap companies in the face of economic uncertainty. “The UK’s small-cap space is incredibly vibrant, with a plethora of innovative companies creating new products and services,” notes a senior analyst at Morgan Stanley. “These companies are not only disrupting traditional industries but also creating new markets, which is driving their outperformance.”

Root Causes

So, what’s behind the UK’s thriving startup ecosystem? One key driver is the country’s talent pool, which is rich in tech-savvy entrepreneurs and engineers. According to a recent report by recruitment firm, Robert Walters, the UK is home to over 1 million tech professionals, making it one of the largest tech talent pools in Europe. This talent pool has enabled the growth of a thriving startup ecosystem, with many entrepreneurs and founders leveraging the UK’s world-class universities and research institutions to develop innovative solutions.

Another key driver is the UK’s regulatory environment, which has made it easier for startups to raise capital and scale their businesses. For example, the UK’s Venture Capital Trust (VCT) scheme has provided entrepreneurs with a tax-efficient way to raise capital from venture capital investors. Similarly, the UK’s Enterprise Investment Scheme (EIS) has enabled investors to claim tax relief on investments in small-cap companies. These regulatory frameworks have helped to create a supportive environment for startups to grow and thrive.
