Fund manage Anthony Bolton last week launched a China fund
An eminent British fund manager, Anthony Bolton, last week launched a fund aimed at putting $1bn into Chinese stocks. He has left retirement for the purpose: China, he explained, is in an “investment sweet spot”, with incomes per head rising and consumption accelerating.
Doubtless, Mr Bolton knows what he is doing. But less experienced hands should beware of an implicit fallacy. The long run evidence shows there is no correlation between economic growth and investment returns.
If that sounds counter-intuitive, remember it is not the opportunity that matters, but the price attached to it. As Adam Smith put it more than two centuries ago, “the chance of gain is by every man more or less overvalued”.
That is, we tend to pay more for growth than it is worth. That applies both to growth stocks and growth economies. And I suspect though it is harder to prove that it also applies to investment by corporations.
The latest Credit Suisse annual study from the academic trio of Dimson, Marsh and Staunton (DMS) gives us 110 years of evidence on this. Among 19 countries covered, the long run correlation between real growth in gross domestic product and real equity returns is in fact slightly negative. The country with the lowest growth, South Africa, had the second highest average equity returns. Italy, with half the growth rate, produced nearly four times the returns.
As for emerging economies, live indices have been around only since the late 1980s. But the study backdates them to 1975, since when emerging markets have returned 1 per cent less per annum on average than developed markets.
But everything depends on the starting date. Since the indices went live, emerging markets have outperformed by 1 per cent. In the past decade they have outperformed by 10 per cent. This looks suspiciously like an emerging fad, prompted by the existence of the indices themselves. In the last decade, we have had Goldman Sachs’ doctrine of the supremacy of the Brics Brazil, Russia, India and China. It is not impossible that all four will achieve developed market status, but it would certainly be unusual. The DMS study simulates emerging and developed markets since 1900, based on per capita GDP.
In that time, five of 38 countries graduated from emerging to developed status, among them Greece and Portugal. Two more, Argentina and Chile, slipped from developed to emerging.
In the past 30 years, it gets worse. Besides Greece and Portugal, only two countries Israel and South Korea moved up a grade. Many more were downgraded from emerging to so called “frontier” status.
This is a handy reminder of the futility of long range forecasting. That said, how to explain the underwhelming performance of emerging equities, besides a simple propensity to overpay for growth?
One strong possibility is that stock markets fail to capture growth adequately. In an entrepreneurial economy, growth is what happens at the grass roots. By the time companies come to the market, the best is over an idea supported by remarkably slow-growing or even shrinking real dividends in almost all countries over time.
Another possibility raised by Smithers & Co is that investors expect countries with fast rising GDP per head to have strengthening currencies. So it makes sense to pay high multiples of earnings at today’s exchange rate, since a rising currency will make good the difference.
If investors do in fact think that, they should be careful. According to Professor Dimson, of the 19 countries in his 110 year study, none has shown average currency movements over the period of more than 1 per cent per annum either way after inflation. Another suggestion from Mr Smithers brings me to a question raised at the outset whether corporate managers, like investors, overpay for growth. Fast growing economies, he says, should have faster depreciation rates, presumably because any given piece of plant or equipment will be obsolete more quickly. It is doubtful, he adds, whether accounting practice recognises this properly.
More generally, companies may be tempted by the lure of high growth to pitch their prices low when first entering a market. Thereafter, their profits will rise rapidly with GDP. But if their starting point is too low, they are making the same mistake as portfolio investors who buy stocks too high. The end result in both cases is a disappointing long term return.
Does this mean you should steer clear of emerging markets? Not at all. In non crisis times they offer diversification, which is worth something in itself. But if you are invested in emerging markets to begin with, you should of course buy some old style, low growth developed market stocks on just the same grounds
