Living
in Southeast Asia gives me the chance to attend the Cambodian water
festival. Locals and tourists pack the streets of the capital city Phnom
Penh, laughing as they splatter each other with water to welcome in the
new year – but the fun often comes at a cost. Pickpockets roam the
crowd, lightening the wallets of the unsuspecting.
Shake your head at the tourists’ naiveté if you must. But most
investors also lose money in crowds. And it costs them far more than it
does Cambodian tourists.
The problem is our tendency to jump on
stocks, bonds or real estate that other people also like. Even if we
haven’t personally profited from Canadian bank stocks or Apple shares,
we feel good about their future prospects, because their prices have
shot up in recent years as the crowd has rushed in. We recoil, however,
when somebody mentions the languishing Spanish or Italian stock markets.
Other investors have fled those troubled regions, so why should we
stick around?
It’s natural to think this way, but it’s a very
expensive habit. Our desire to be part of the pack is a key reason why
individual investors in 17 fund categories do far worse on average than
the typical funds in those same categories, according to research firm
Morningstar.
Investors fall behind because they can’t resist the
temptation to jump out of areas with poor recent returns and hop into
sectors that have already gone up. This habit ensures most of us sell
low and buy high – just the opposite of what we should be doing – and
typically shaves 2.5 per cent a year off our returns compared to how we
would have fared by simply standing pat, according to the Morningstar
study.
Avoiding this tendency can provide a big boost to your
returns – and the way to do so is simple. Just develop a plan for
allocating the assets in your portfolio across many different areas and
types of assets, then rebalance your portfolio once a year to get back
to your target allocation.
The great psychological challenge is
the annual rebalancing. It means taking a deep breath, trimming back on
your winning investments, and putting money into areas that have been
falling – going where the crowd isn’t.
This pulls against the way
most of us think. A good example of the problem: Readers constantly
question why I have selected an international mix of index funds for my Strategy Lab portfolio. Don’t I know that Canadian markets have thumped the competition for much of the past decade?
I
do. Nobody, though, can consistently predict which markets will do well
in the future. Who would have looked at the lacklustre U.S. economy
back in January and guessed that the S&P 500 would have soared to
double-digit gains this year, handily outpacing the Toronto market?
The
easiest way to make sure you’ll benefit from whatever happens is to set
up a global portfolio of low-cost index funds, then rebalance once a
year. Say your overall goal is to have a mix of 30 per cent Canadian
stocks, 30 per cent international stocks and 40 per cent bonds in your
portfolio. If your Canadian stock index fund has made big gains and now
constitutes 45 per cent of your holdings, you would sell some and pour
the proceeds into your international stock index fund and your bond
index fund to get back to your 30-30-40 target.
Rebalancing is a
way of acknowledging that different assets bloom at different times. For
instance, bonds typically outperform stocks during the first stages of
economic weakness as investors flee to their perceived safety. Stocks
usually start outperforming bonds before a recession officially ends.
It’s
next to impossible to predict when these shifts will take place, but a
disciplined system of rebalancing ensures you’re not piling into a hot
sector just as it cools. In a study titled Does Portfolio Rebalancing Help Investors Avoid Common Mistakes?,
Steven Beach and Clarence Rose, professors of finance at Radford
University, show that regular rebalancing produces better returns than
chasing top performing sectors.
Rebalancing works best if you have
a diversified portfolio that is spread out among several asset classes,
ranging from Canadian stocks to global bonds. A lot of investors resist
this notion – some, for instance, prefer an all-Canadian portfolio
because they perceive it as safer than risky emerging-market stocks and
the like.
I can understand how they feel, but those investors
should remember that there are long periods – such as much of the 1990s –
when Canada’s markets lagged behind the U.S. market and other global
alternatives.
Think of it this way: A global portfolio ensures
that if there’s a party going on for investors anywhere in the world,
you’ll participate in it. Meanwhile, rebalancing ensures that you’re not
having your pockets picked by blindly following the crowd. Both
strategies make sense, whether you’re in Cambodia or Canada.
