This Big Bet Will Bring You Down

Published in Investing on 26 August 2010

Black swans are all the rage. But rather than focusing on what might happen, staying diversified and sticking to the basics is your best bet for creating long-term wealth.

Everyone seems to be looking for big wins from the markets. Yet time and time again, what's proven to be the best strategy is to take a more conservative, long-term approach with your investments. Too often, if you try to put all your money in one basket, you'll end up with nothing.

Hunting swans

A recent article in the Wall Street Journal observed how an increasing number of investors are looking for ways to profit from an unexpected event, such as a market crash. Known as black swan events, these surprises cause huge amounts of turbulence in the markets, and for most investors who own shares, they can bring big losses in a short period of time.

Some of the strategies people use to cash in on black swan events, however, are exceptionally risky. 

Sophisticated hedge funds use securities like index-based derivatives and privately placed investments to try to take advantage of underestimates of "tail risk" in certain markets. Even average investors are getting in on the action, using spread bets or put options to try to protect themselves from a potential downturn.

The article suggests, though, that such strategies are necessary because old-style diversification hasn't worked well recently. Proponents of black swan strategies argue that during the financial crisis, most markets moved downward at the same time, and therefore those who counted on diversification to save them were sorely disappointed.

Missing the forest for the trees

It's entirely possible that black swan-based strategies may be smart long-term plays. If the markets are indeed underestimating the chance of a catastrophic downturn, then investing a portion of your portfolio could indeed be the right thing to do. 

Investors like US hedge-fund manager John Paulson, for instance, made a killing taking the unpopular position that a housing bubble would burst.

But focusing entirely on black swan events means taking your eye off the real goal of your investing: to maximise your wealth over the long haul. 

It's true that protecting your wealth during bad times is just as important as, if not more important than, maximizing your gains during a bull market. It's true that it can be almost impossible to recover from a big loss. 

If you're not careful, though, the protection you try to buy can be so costly that it takes away any chance you have of reaching your goals if the worst-case scenario never happens.

Diversification still works

Those who say diversified portfolios failed during 2008 and 2009 simply didn't own the right investments. Corporate bonds did suffer along with shares. But if you stuck with Treasury bonds in the US or gilts here in the UK, then you saw excellent gains in 2008 to offset the big fall in the FTSE 100 index.

The prospect of a black swan event is interesting and worth thinking about. But if you let it dominate your attention, you'll miss out on smart investing opportunities throughout the market. 

In contrast, if you can stay focused on the big picture, you'll be more likely to reach all of your long-term investing goals.

I thought that Buffett favours large, concentrated positions that he understands and can see intrinsic value clearly-not diversification?

Be careful with Buffett. What he says, or is wrongly reported to have said, and does are not necessarily consistent over time. Although he has shunned diversification for its own sake (usually in his argument against reliance on beta), his portfolio is actually incredibly diversified.

Trying to imagine Black Swan events (and develop suitable portfolio protection strategies) is a fun way to lose about 1% of your net-worth each year whilst building in enormous upside potential if it ever comes to pass.

However, to conclude that you should employ excessive diverse(worse)-ification, in the rest of your portfolio, is a huge leap because such a portfolio cannot hope to outperform the market; only mimic its long term average and there are much safer ways for the no-nothing investor to save for the future...

Great article from the Fool, as it is my favourtite subject : Passive investing. Loved the part about the t-bills providing an 'uncorrelated asset class' to complement the equities. This article is similar to what the Gurus at Bogleheads always talk about.

Now if only TMF can help us with some simple model portfolios for the UK investor that one can implement with Vanguard funds and ETFs, and just occasionally rebalance, that would be great.

For the US investor, there is a wealth of information to DIY starting from Bogleheds, as well as these amazing sites : Plenty of easy to understand articles, plus model portfolios : Amazingly well written, with simple ideas on how to implement, that is so quintessentially American. From my days in the US, I can say that they are great at taking complicated subjects and explaining it in a simple way for the layman to understand.

Also, nowadays due to globalization, people move between various countries and have assets scattered all over. Thats my situation. Some articles and books advising such people on simple passive investment strategies would also be great.

Thanks

TamesisChild > such a portfolio cannot hope to outperform the market

True, but do you *need* to outperform the market in order to accomplish your long term goals ?
I quote William Bernstein, from http://www.efficientfrontier.com : "If over the past 10 or 20 years you had simply held a portoflio consisting of one quarter each of indexes of large U.S. stocks, small U.S. stocks, foreign stocks and high quality U.S. bonds, you would have beaten over 90% of all professional money managers and with considerably less risk."

You can also take a look at http://www.fundadvice.com/articles/buy-hold/fine-tuning-your-asset-allocation.html
To me, those returns are not bad at all.

Okay, past does not predict future, yada, yada, yada but this approach provides a consistent, scientific strategy to invest.

Of course they dont compare to Buffett's 20%+ returns or Anthony Bolton's or the hedge fund guys such as James Simmons of Renaissance Technologies or Steven Cohen of SAC Capital or Christian Siva-Jothy of SemperMacro, but (a) I cannot identify the Buffetts and the Boltons upfront, and (b) I cannot get access to hedge funds, and even if I did, I know they can collapse spectacularly occasionally, just as LTCM did in 1998.

Of course the Fool has been teaching us that an individual investor can outperform the market, and I believe that to some extent, but dont have the time or indeed the ability to do it consistently. Most of it is making very good judgement calls and I could get it wrong, and may not have the mental strength to continue to hold the investment and compound it. And without compounding, it is no use investing. There is no use having a great idea and just growing my £1000 to £2000 in a short time and stopping there ("taking profits"). I would rather have a strategy where I can feel free to allow the money to grow / compound. To me, therein lies the true power of investing. So I wouldnt dismiss passive investing. It is not such a bad idea after all.

Such as ? Property perhaps ?
