Thematic investing

the thematic investment approach

Built to deliver: thematic equity portfolios

March 2019

How every aspect of the thematic portfolio construction process is geared to helping investors secure better returns from their equity investments. 

Why do we believe Pictet Asset Management’s Thematic Equity strategies have the potential to generate investment returns that are superior to mainstream stocks? There are a number of reasons.

Stock returns fuelled by powerful, long-term trends

The first is that returns from thematic equities stem from trends that are both long term in nature and largely unaffected by the ups and downs of the economic cycle.

In the health industry, for example, many companies have benefited from a persistent rise in health care spending worldwide. This is due to a major structural trend, the rise in life expectancy of the populations of the developed world. As Fig.1 shows, investment in health is rising at an accelerating pace, particularly in the emerging world. Experience shows this is unlikely to be derailed by any slowdown in the broader economy.

In the clean energy industry, meanwhile, the transformative power of climate change continues to drive investment in alternative sources of power. The technological advances that are emerging as a result of this wave of investment are helping slash the cost of renewable power. Production costs for onshore wind and solar power are expected to fall by 40 per cent and 60 per cent respectively by 2040.

At Pictet Asset Management, we dedicate significant resources to the study of the non-economic megatrends that are reshaping the investment landscape. The 14 trends we have identified (see Fig. 2) form the basis of each of our thematic equity strategies.

Specialised companies better placed to deliver better returns

The second positive attribute that thematic stocks share is specialisation. The companies we invest in are attractive because they’re specialists in a particular field, not generalists whose activities span a broad range of industries or sectors.

And specialisation tends to be associated with higher returns.

There is a large body of evidence showing that the stocks of specialised firms do better than those of large, diversified companies over the long run. Essentially, large firms suffer from what is known as the “conglomerate discount”. Or, put another way, broadly diversified companies are worth less than the sum of their parts.

A study by the Boston Consulting Group (BCG) found that more complex the business, the more inefficient its investment. And, more importantly, the same study also established that wasteful investment acted as a drag on company stock prices.

By contrast, specialised firms – sometimes known as “pure play” companies – typically have a much clearer view of their strategic priorities and concentrate spending in areas that promise the strongest growth. Their capital allocation is more efficient which, in turn, builds a premium into their share prices over time, the BCG research found.

The companies we invest in are attractive because they're specialists in a particular field not generalists whose activities span a broad range of industries.

The upshot for investors is clear: a portfolio composed of the stocks of specialised companies – firms with three or fewer large divisions - should do better than a portfolio of diversified firms over the long run, other things being equal.

Our thematic strategies are designed to take advantage of this tendency. For each thematic strategy we manage, there are explicit rules for the construction of the portfolio. Each stock must have a high “thematic purity” for it to qualify as a potential thematic investment. Thematic purity is a proprietary, numerical indicator of how specialised a company’s activities are.

The higher the rating, the more specialised the firm. If, for example, a company within our Pictet-Water strategy is found to have a purity of 50, this means that half of its enterprise value is derived from marketing products and services that cater to the water industry. The average purity of the companies in our thematic portfolios is at least 65.

Specialist investment managers, not generalists

The specialist skill of our investment managers is another distinguishing feature of Pictet AM's thematic approach. Each thematic strategy is managed by a dedicated investment team, which carries out its own research and constructs its own portfolio. Every team member is a portfolio manager, sharing responsibility for the management of the strategy.

By dedicating all their attention to a clearly-defined group of stocks, investment managers develop distinctive, specialist expertise. This gives thematic equity investment managers a valuable advantage over traditional global equity funds, which work rather differently.

Most mainstream global equity funds are run by managers that are supported by several analysts, whose task it is to generate lists of their best ideas within their designated industry sectors. Often, portfolio managers struggle to process the vast amounts of data emanating from the thousands of stocks that form their universe.

An additional problem is that global or regional equity funds rarely confine themselves to the very best investment ideas their analysts have identified.

Thematic equity investment managers focus on a narrower range of companies and industry segments... this detailed knowledge can simplify the investment process, producing a more focused portfolio.

By contrast, thematic equity investment managers focus on a narrower range of companies and industry segments. This means they are able to build specialist expertise. And this detailed knowledge can simplify the investment decision making process, producing a more focused portfolio whose sources of return and risk are not only distinct but also more clearly understood. This, in turn, can increase the probability of generating better returns. There is ample evidence that selecting stocks from within specific industries – rather than across a broad range of sectors – can deliver better returns.

Thematic stocks don't feature in mainstream indices

Companies that qualify as thematic investments share another attractive attribute: they do not feature prominently in traditional stock market indices. This has important investment implications. The stocks that find their way into the vast majority of the world’s equity funds are, by and large, constituents of major indices such as the FTSE 100 or the S&P 500 Index.

The result: a portfolio that is destined to generate sub-par returns.

By contrast, thematic equity strategies invest in specialised firms that are not represented in established benchmarks. Essentially, the approach is index agnostic.

Built to deliver

So with specialist investment managers investing in specialised companies in dynamic industries, we believe we can build a portfolio that draws on the very best of human ingenuity. It’s what sets our actively-managed thematic equity funds apart. It’s also what can help investors get the most from their equity investments.
