One of the firms we watch closely here at The Acquirer’s Multiple is GMO and its co-founder, Jeremy Grantham. Grantham successfully predicted numerous financial asset bubbles. He warned against the dot-com bubble and vulnerability in the U.S. stock market leading up to the financial crisis. Over the years his shareholder letters have provided valuable insights for investors. One of my favorites is his 2012 letter in which he provides ten timeless investing lessons under the heading – Investment Advice from Your Uncle Polonius(#).
Here’s an excerpt from that letter:
For individual investors setting out on dangerous investment voyages.
1. Believe in history. In investing Santayana is right: history repeats and repeats, and forget it at your peril. All bubbles break, all investment frenzies pass away. You absolutely must ignore the vested interests of the industry and the inevitable cheerleaders who will assure you that this time it’s a new high plateau or a permanently higher level of productivity, even if that view comes from the Federal Reserve itself. No. Make that, especially if it comes from there. The market is gloriously inefficient and wanders far from fair price but eventually, after breaking your heart and your patience (and, for professionals, those of their clients too), it will go back to fair value. Your task is to survive until that happens. Here’s how.
2. “Neither a lender nor a borrower be.” If you borrow to invest, it will interfere with your survivability. Unleveraged portfolios cannot be stopped out, leveraged portfolios can. Leverage reduces the investor’s critical asset: patience. (To digress, excessive borrowing has turned out to be an even bigger curse than Polonius could have known. It encourages financial aggressiveness, recklessness, and greed. It increases your returns over and over until, suddenly, it ruins you. For individuals, it allows you to have today what you really can’t afford until tomorrow.
It has proven to be so seductive that individuals en masse have shown themselves incapable of resisting it, as if it were a drug. Governments also, from the Middle Ages onwards and especially now, it seems, have proven themselves equally incapable of resistance. Any sane society must recognize the lure of debt and pass laws accordingly. Interest payments must absolutely not be tax deductible or preferred in any way. Governments must apparently be treated like Polonius’s children and given limits. By law, cumulative government debt should be given a sensible limit of, say, 50% of GDP, with current transgressions given 10 or 20 years to be corrected.) But, back to investing …
3. Don’t put all of your treasure in one boat. This is about as obvious as any investment advice could be. It was learned by merchants literally thousands of years ago. Several different investments, the more the merrier, will give your portfolio resilience, the ability to withstand shocks. Clearly, the more investments you have and the more different they are, the more likely you are to survive those critical periods when your big bets move against you.
4. Be patient and focus on the long term. Wait for the good cards. If you’ve waited and waited some more until finally a very cheap market appears, this will be your margin of safety. Now all you have to do is withstand the pain as the very good investment becomes exceptional. Individual stocks usually recover, entire markets always do. If you’ve followed the previous rules, you will outlast the bad news.
5. Recognize your advantages over the professionals. By far the biggest problem for professionals in investing is dealing with career and business risk: protecting your own job as an agent. The second curse of professional investing is over-management caused by the need to be seen to be busy, to be earning your keep. The individual is far better-positioned to wait patiently for the right pitch while paying no regard to what others are doing, which is almost impossible for professionals.
6. Try to contain natural optimism. Optimism has probably been a positive survival characteristic. Our species is optimistic, and successful people are probably more optimistic than average. Some societies are also more optimistic than others: the U.S. and Australia are my two picks. I’m sure (but I’m glad I don’t have to prove it) that it has a lot to do with their economic success.
The U.S. in particular encourages risk-taking: failed entrepreneurs are valued, not shunned. While 800 internet start ups in the U.S. rather than Germany’s more modest 80 are likely to lose a lot more money, a few of those 800 turn out to be today’s Amazons and Facebooks. You don’t have to be better; the laws of averages will look after it for you.
But optimism comes with a downside, especially for investors: optimists don’t like to hear bad news. Tell a European you think there’s a housing bubble and you’ll have a reasonable discussion. Tell an Australian and you’ll have World War III. Been there, done that! And in a real stock bubble like that of 2000, bearish news in the U.S. will be greeted like news of the bubonic plague; bearish professionals will be fired just to avoid the dissonance of hearing the bear case, and this is an example where the better the case is made, the more unpleasantness it will elicit.
Here again it is easier for an individual to stay cool than it is for a professional who is surrounded by hot news all day long (and sometimes irate clients too). Not easy, but easier.
7. But on rare occasions, try hard to be brave. You can make bigger bets than professionals can when extreme opportunities present themselves because, for them, the biggest risk that comes from temporary setbacks – extreme loss of clients and business – does not exist for you. So, if the numbers tell you it’s a real outlier of a mispriced market, grit your teeth and go for it.
8. Resist the crowd: cherish numbers only. We can agree that in real life as opposed to theoretical life, this is the hardest advice to take: the enthusiasm of a crowd is hard to resist. Watching neighbors get rich at the end of a bubble while you sit it out patiently is pure torture.
The best way to resist is to do your own simple measurements of value, or find a reliable source (and check their calculations from time to time). Then hero-worship the numbers and try to ignore everything else. Ignore especially short-term news: the ebb and flow of economic and political news is irrelevant. Stock values are based on their entire future value of dividends and earnings going out many decades into the future. Shorter-term economic dips have no appreciable long-term effect on individual companies let alone the broad asset classes that you should concentrate on. Leave those complexities to the professionals, who will on average lose money trying to decipher them.
Remember too that for those great opportunities to avoid pain or make money – the only investment opportunities that really matter – the numbers are almost shockingly obvious: compared to a long-term average of 15 times earnings, the 1929 market peaked at 21 times, but the 2000 S&P 500 tech bubble peaked at 35 times! Conversely, the low in 1982 was under 8 times. This is not about complicated math!
9. In the end it’s quite simple. Really. Let me give you some encouraging data. GMO predicts asset class returns in a simple and apparently robust way: we assume profit margins and price earnings ratios will move back to longterm average in 7 years from whatever level they are today. We have done this since 1994 and have completed 40 quarterly forecasts. (We started with 10-year forecasts and moved to 7 years more recently.) Well, we have won all 40 in that every one of them has been usefully above random and some have been, well, surprisingly accurate.
These estimates are not about nuances or PhDs. They are about ignoring the crowd, working out simple ratios, and being patient. (But, if you are a professional, they would also be about colossal business risk.) For now, look at the latest of our 10-year forecasts that ended last December 31 (Exhibit 1). And take heart. These forecasts were done with a robust but simple methodology. The problem is that though they may be simple to produce, they are hard for professionals to implement. Some of you individual investors, however, may find it much easier.
10. “This above all: to thine own self be true.” Most of us tennis players have benefited from playing against nonrealists: those who play to some romanticized vision of that glorious September day 20 years earlier, when every backhand drive hit the corner and every drop shot worked, rather than to their currently sadly atrophied skills and diminished physical capabilities. And thank Heavens for them. But doing this in investing is brutally expensive.
To be at all effective investing as an individual, it is utterly imperative that you know your limitations as well as your strengths and weaknesses. If you can be patient and ignore the crowd, you will likely win. But to imagine you can, and to then adopt a flawed approach that allows you to be seduced or intimidated by the crowd into jumping in late or getting out early is to guarantee a pure disaster. You must know your pain and patience thresholds accurately and not play over your head.
If you cannot resist temptation, you absolutely MUST NOT manage your own money. There are no Investors Anonymous meetings to attend. There are, though, two perfectly reasonable alternatives: either hire a manager who has those skills – remembering that it’s even harder for professionals to stay aloof from the crowd – or pick a sensible, globally diversified index of stocks and bonds, put your money in, and try never to look at it again until you retire. Even then, look only to see how much money you can prudently take out.
On the other hand, if you have patience, a decent pain threshold, an ability to withstand herd mentality, perhaps one credit of college level math, and a reputation for common sense, then go for it. In my opinion, you hold enough cards and will beat most professionals (which is sadly, but realistically, a relatively modest hurdle) and may even do very well indeed.
Good luck. Uncle Polonius
(#) Polonius, a character in Hamlet, a verbose, self-important advisor to the King, was clearly intended to be a real loser, but curiously in the end Shakespeare couldn’t resist making most of his ponderous advice actually useful and memorable. His famous speech to his son Laertes who is embarking on a dangerous sea voyage to France (from Denmark) is reproduced as an Appendix. (Hamlet makes genocidal if rather unintentional war on the Polonius family, accounting for Laertes, his sister Ophelia, and poor Polonius himself: a clean sweep.)
