Narrative
Risk
The
Economist tells us that
“the emerging market slowdown is not the beginning of a bust. But it is a
tuning point for the world economy.” Growth, to cut to the chase, will be lower
in China and across the emerging market realm. Some pundits look at
this reasonable assumption and warn that it’s the beginning of the end; we’ve
crossed the Rubicon as it relates to the global economy and international
investing. Actually, there’s far less drama to this story. Narrative risk, as
Barry Ritholtz explains, may be lurking. Indeed, if you’re
looking at the evolution of emerging markets through the prism of certain media
headlines of late, the end appears to be nigh, at least for this week.
Perhaps
the bigger issue is one of managing expectations. Emerging markets have had a
good run, an extraordinary run, in fact, if you choose your look-back period
carefully. But let's think about this from a different perspective. Consider
rolling three-year annualized returns for these countries in comparison with
the US stock market (S&P 500) and foreign equities in
developed markets (MSCI EAFE). By this standard, the track record for emerging
markets looks a bit more complicated from an investment angle. Indeed, there
are periods of above- and below-average performance. Shocking, isn’t it?
In
the late-1990s, I recall talking to numerous financial advisors who complained
that they had been sold a false bill of goods. Emerging market equity funds at
the time were an innovative concept, and one that relatively few investors had
embraced. A few early adopters jumped on the bandwagon, largely because of
several influential research studies that highlighted the impressive track
record in these stocks. As an added bonus, the diversification benefits were
potent, i.e., return correlations were quite low vs. US and
foreign-developed-market stocks.
But
the cult of equities in, say, 1999 was dominated by US stocks. It was hard not
to notice, with the S&P 500 routinely delivering 20%-to-30% annual returns.
Owning emerging market stocks, by contrast, looked like a wet dish rag as the
new millennium approached.
Since
then, emerging market stocks have rallied, crashed, and rallied again.
Something similar can also be said about US and foreign developed-market
stocks, albeit in varying degrees. But now we’re told by some that the party’s
over for emerging market stocks, or at least that the celebrations from here on
out will be toned down by more than trivial amounts.
The
truth is that we didn’t wake up today and find that what had been an
extraordinary investment opportunity last night had suddenly become dirt. The
real story is that as the world has become increasingly globalized, and markets
have become ever more securitized, expected return for the long run generally
has inched down. This is almost certainly true for emerging market stocks, but
it’s no less relevant for the rest of the planet’s equities (and bonds, real
estate and commodities). For the same reason that you should expect that
Apple’s growth rate will slow in the years ahead relative to history, the same
applies to emerging markets. The low hanging fruit of return has been picked.
We've been here before, with countries, with asset classes, and individual
companies. Trees don't grow to the sky.
But
there's more to this story. From an asset allocation perspective, it’s prudent
to assume that expected return is in constant flux in shorter periods. Yes, as I discussed last week, it’s reasonable to assume that
diversification benefits will fade through time. Earning a risk premium is
going to get tougher, all else equal. Gravity prevails eventually.
This
isn’t news, even if it’s tempting to treat it as such. If you think you've
heard this somewhere before, you're right. The ancient writings a la the
efficient markets hypothesis and the capital asset pricing model imply that the
"market" portfolio's return is likely to trend lower rather than
higher over time. The rate of decline is unknown, but it's tempting fate to
assume that the performance of beta in the coming decades is going to rise.
This
isn’t a new development; it’s been with us all along. It’s hardly a smooth
process where, say, expected return drops by five basis points every year like
clockwork. And just to keep things interesting, the process reverses itself at
times and ex ante performance goes up. Over longer stretches, however, it’s
going to be tough to escape the terminal slide. In a world crawling with
institutions armed to the teeth with computer-based quantitative strategies,
searching through every nook and crevice of markets, the long, slow descent of
risk premia will yield to financial gravity.
That
said, it’s a mistake to focus on one piece of the major asset classes and single it out for abuse.
What
hasn’t changed is that over shorter periods there will be quite a lot of
volatility in expected return, for all the asset classes. What should we do? More
of the same. Diversify broadly (which is about as hard as falling asleep) and
spend most of your time on designing and managing a rebalancing strategy.
Oh,
yes, one more thing: Don’t get tangled up in narrative risk. Why? Because
turning points, in both major and minor forms, are a dime a dozen—there’s
always another one coming.
