There's nothing special about a year. It's just the time it takes for the earth to circle the sun. But we use the calendar to make all kinds of judgements and predictions, forecasting what we think will happen over the coming 365 days.
The first week of 2013 has seen a flood of articles prophesying the events of the next 12 months.
My Motley Fool colleague Scott Phillips avoided the temptation, instead listing 12 timeless investing resolutions.
On that same theme, rather than insult you with another list of predictions for the year ahead, I find it more valuable to look back at how some of last year's prediction lists fared.
A year ago, analysts were making a variety of predictions, but there was one common theme: Most of them were wrong. Dead wrong.
So let's review some of last year's biggest predictions that never came true -- not because we want to point fingers, but because you can often learn more from people's mistakes than from their successes.
1. Barron's: U.S. interest rates will rise
A year ago, Barron's began its "2012 Forecast" article with a prediction that left no wiggle room: "Yields on 10-year Treasuries don't have anywhere to go but up in the next year."
But there was another place they could go: down. And that's where they went. Interest rates on 10-year Treasuries began the year at 1.97% and closed at 1.73%.
U.S Treasury bonds have been in a bull market for 30 years. Someday that will end, and interest rates will rise. But no one knows when, and trying to predict a turn is maddeningly difficult.
U.S. Treasuries have gained more than 20% since America's credit rating was downgraded in 2011 -- the opposite outcome of what almost everyone expected.
Traders have been predicting the end of low interest rates in Japan for nearly two decades, and for nearly two decades, they've been wrong. These things can last much longer than anyone expects.
2. Todd Schoenberger: U.S. stocks to crash 35%
A day before Christmas 2011, analyst Todd Schoenberger said, "We're predicting the S&P 500 will be down 20% by mid-year, and by the end of the year, we'll be down 35%. ... Buyer beware."
The S&P 500 finished the year up 14%. The Dow Jones gained 15%. Far from "buyer beware," the reality was "buyer, prepare for one of the best years of the last decade."
Stocks will crash again someday. Count on it. But again, the when is virtually impossible to predict.
The key to successful investing isn't predicting when a crash will occur, but rather being ready for one when it inevitably comes -- preparedness, not prescience.
3. Greece will leave the Euro
Many made this prediction a year ago. Citigroup predicted that Greece would leave the euro on Jan. 1, 2013 (it didn't). In December 2011, London mayor Boris Johnson predicted a Greek exit as well. The BBC wrote:
"I would be amazed if we were all sitting here next year and the euro had not undergone some sort of change," Mr Johnson [said]. ... "I think it highly likely that there will be a realignment in the sense that some countries will fall out ... and we all know who the likely candidates are," he said, adding that ouzo would be "substantially cheaper" in a year's time.
Here's a good rule of thumb for what's going to happen in Greece: No one has any idea what is going to happen, ever.
The forces that dictate events like Greece leaving the euro are political, not economic, and no sane person would ever claim to understand the irrationality of a politician's mind.
Nassim Taleb once wrote: "The best test of whether someone is extremely stupid (or extremely wise) is whether financial and political news makes sense to him."
Bonus fact: Greek stocks returned 33% in 2012, making it one of the best regions in the world to invest in.
Hot air galore
Go down the list of pundit predictions, and you'll find this same story again and again. The track record of financial experts foretelling the next 365 days is dreadful -- so bad, in fact, that assuming the opposite of what they predict may be the best strategy.
If I could offer two tips on how to react to analyst predictions, they would be:
- Avoid those who talk in certainties. The most reliable forecasters think in probabilities. Saying a recession is guaranteed this year is ludicrous and ignorant of history. On the other hand, saying there's a 70% probability of a recession may be a prediction worth paying attention to. They are vastly different calls.
- Listen to people who talk about their mistakes. One of the keys to making good forecasts is constantly updating your thoughts when new information arises. That can mean changing views entirely. In 2009, CNBC host Larry Kudlow proudly announced, "I have not changed my point of view for my entire adult life." I struggle to think of a worse trait for someone hoping to understand the world. The guy you want to listen to is the one who is constantly saying: "I was wrong. Here's why, and here's how it's changing my outlook."
Here's to a happy, safe, healthy, yet most unpredictable 2013.
