As an active long-term investor, we aim to create sustainable value for our clients in a way that also has a positive impact on wider society. We believe that building an inclusive organization will unlock the power of diversity, and by embracing difference, we will achieve better performance and more innovation. For us, striving for inclusion and diversity is not only the right thing to do; it’s the only thing to do.
While investors can approach 2021 with optimism that an effective Covid-19 vaccine will be available, the path of the economic recovery remains unclear. A broader toolkit of investments is needed – not just the regions, sectors and strategies that have recently done well.
We are pleased to introduce The Investment Intelligence Podcast, where experts discuss all things investing, from recent market developments, to strategy, sustainable investing, asset allocation, risk management and more.
Today’s high-tech innovations have not only failed to lift official productivity measurements, but they could be less likely to boost overall equity returns than many people think. Our research shows that investors may need to be very selective and active to capitalize on the technology boom.
Even if new high-tech developments eventually boost productivity growth, which remains puzzlingly low, equities in general are not likely to benefit automatically
Our research shows that attractive long-term equity returns have only occasionally coincided with major technological innovations throughout history
High valuations are a key reason why innovation has had a limited market impact in the past: many investors have overpaid for future growth potential, which increased the odds that ensuing returns would be low
Rather than looking for a broad market boost from technological innovation, investors should focus more on “disrupting sectors” – AI-related industries, for example – and on becoming more active as the pace of innovation increases
There is an ongoing debate among economists about when – or even if – today’s new technologies will generate productivity growth, which has been languishing for decades. Yet our research shows that even if high-tech gains manage to boost productivity, equities in general are not likely to benefit automatically.
This emphasizes the need for investors to be active in identifying future wininers, to not overpay for growth potential and, most importantly, to be patient enough to let their decisions play out.
A low correlation between innovation and positive long-term returns
As the accompanying chart shows, attractive long-term equity returns have only occasionally coincided with major technological innovations throughout history – and these results were not consistent.
Periods of above-average returns followed the introduction of mainframe computers and nuclear energy in the 1950s, the development of the PC in the mid-1970s and the debut of the web and new mobile phones in the early 1990s.
Periods of below-average returns occurred after several major technological innovations, such as the invention of the telephone (1876), the roll-out of electricity in Western cities (1882), and the invention of autos (1886), radios (1920) and plastics (early 1930s).
Short-term windows of opportunity followed the invention of the steam engine (1781), the introduction of railways (1825) and the advent of modern steel production (1850s). However, those who came in a bit late experienced low, and sometimes even negative, real returns. In the late 1990s, many technology investors learned this lesson the hard way.
Major innovations have not consistently led to superior equity returns

We looked at rolling ten-year real UK equity returns since the late 18th century and at rolling ten-year simple average returns of 15 global equity markets from 1870 onwards until 2017. We chose the UK because it was the world’s dominant economy and super-power until World War I.
High valuations are a key reason why innovation has had a limited market impact
So why is it that periods of major technological innovation haven’t consistently coincided with superior long-term equity returns? We believe there are three primary reasons.
First, it is important to reiterate that innovation and productivity are not identical. Any new technological breakthrough can lead to higher productivity, but it might be accompanied by a substantial time lag.
Second, other negative factors can more than offset the positive impact of new technologies on productivity. For example, World Wars I and II were major global events that held back productivity in the 1910s and 1940s, respectively.
Third, and most important from an investment perspective, valuations matter. The S&P 500 index’s cyclically adjusted price-to-earnings (CAPE) ratio was particularly high during many previous periods of high-tech innovation – such as the “go-go years” of the mid-1960s, and the dot-com bubble of the late 1990s and early 2000s. During times like these, investors simply overpaid for the chance to enjoy future growth potential, which increased the likelihood that ensuing market returns would be low.
It is important to note that today, the S&P 500’s CAPE is again at a stretched level of around two times its long-term average – similar to the level seen in 1929 – which suggests that overall US equity returns in the coming decade are likely to be low compared to their long-term averages. Somewhat fittingly, some of the biggest drivers of the recent stockmarket boom have been high-tech innovators such as the FANG stocks: Facebook, Amazon, Netflix and Google.
Even though technological innovations by themselves do not necessarily bode well for broad equity market returns, investors can still capitalize on innovation in a broader sense.
Innovation can have a larger impact at the sector level
Our research has found that in the past, “disrupting” sectors – those representing technological innovations – tended to outperform the broad market during long stretches of time after the innovation was made. This could mean that sectors and companies related to, for example, artificial intelligence might continue outperforming as long as valuations are not excessive. We are thinking in particular of stocks associated with AI infrastructure (big data, the “internet of things” and cloud computing), AI applications (robotics and deep learning) and AI-enabled industries (the health care, transportation and automotive sectors are just a few).
As the pace of innovation increases, active management becomes more important
Another important market implication to highlight is the pace at which today’s high-tech changes are unfolding. Consider that it took around 100 years until railways were used by half of the countries worldwide, but less than 10 years for the internet to be adopted by a similar number of nations. This shows that investors have increasingly less time to assess the impact of innovations and to identify winning sectors, let alone the most attractive individual companies within those sectors. Joseph Schumpeter’s “creative force of destruction” – which these days is called “disruption” – seems to be growing ever stronger. This clearly strengthens the case for active investment management.
Only time will tell whether new technological innovations will help the global economy become structurally more productive. Nevertheless, innovation clearly matters for investors, but innovation doesn’t translate easily into positive portfolio returns. To identify future winners, we suggest that investors consider an active approach to investing, and we caution them to not overpay for growth potential. Most importantly, however, we stress the importance of patience.

In May 2018, a number of China’s A-shares will become part of MSCI’s flagship emerging-market index for the first time, and we believe investor interest is likely to grow. But in many ways, this market is as misunderstood as it is underrepresented in portfolios, so here are 10 things investors should know.
China’s stock markets were once notoriously difficult to access, but the government has made a concerted effort to open its markets – including launching the Stock Connect programmes
The MSCI Emerging Market index – the benchmark for EM investors globally – will soon include China A-shares for the first time, sending an important signal about the credibility of A-shares
High stock turnover, more institutionalized markets and reduced stock suspensions are opening investors’ eyes to China: an estimated USD 18 billion is set to be allocated to A-share markets
