The National Bureau of Economic Research's (NBER's) Business Cycle Dating Committee identifies the beginning and ending dates of U.S. Recessions. Although we have yet to hear from them on an official date for the start of a new recession, there is little doubt in my or my colleagues' minds that we are in one. You may think that this should lead to a recommendation to sell stocks until a healthy economy is once again in place. I strongly recommend against jumping to that conclusion.

Attempting to time your exit from and re-entry into the stock market based on the perceived state of the economy offers small chance of adding value to your portfolio unless you possess amazing skills in foretelling these beginning and ending dates. Most of us (yours truly included), just can't do it. In fact, if history is any guide at all, the best buying and selling times around recessions are most likely to be points in which the data are unclear at best and, in most cases, dramatically misleading.

The Lagged Data & Analysis Factor
The NBER looks at data on personal incomes, employment, industrial production, sales and estimates of changes in GDP to determine the level of economic activity that leads to identifying turning points in the economy. But even they don't have sufficient evidence to identify these points until after some time has passed. They didn't identify the last recession's starting point, March 2001, until eight months later (November 2001). The committee took 20 months to determine that the recession ended in November 2001, making its announcement in July 2003. So, although my colleagues and I believe a recession started months ago (and I'd guess that most Americans share those sentiments), nobody knows. And we won't know for sure until we hear it from the NBER some time in the future.

Now, consider this: Even if you could intuit those economic turning points, you're likely to miss the best times to change your equity allocation, because the market and the economy move in different phases.

A Brief History of Recessions
Since 1953-54, the U.S. has experienced nine recessions not counting the one we're probably in now. That, by the way, isn't cause for undue alarm. Recessions are part of the economic cycle. The federal government can try to shorten recessions and decrease their severity, but it can't make them go away. Investors must learn to live with that.

Those nine recessions averaged 10.3 months in duration. Two recessions (1973-75 and 1981-82) lasted sixteen months. (The recession that kicked off the Great Depression lasted 43 months.) The shortest "recent" recession (1980) lasted only six months. The last recession (2001), as I mentioned, was eight months in duration.

So let's see what would have happened if you'd been able to time the economy—to identify the peaks (booms) and troughs (busts).

Surprising Periods of Best Returns
I gathered two sets of data. The return data in these tables is index data. While they can't be invested in directly, indexes tend to be good proxies for the market. The top row of numbers represents months until peak or trough months following peak or trough for each of the nine most recent recessions listed at left. The first (Table #1) looks at when it might have been best to get out of the market heading into a recession. The second (Table #2) examines when it would have been best to get in heading out of a recession.

Admittedly, this data provides a lot of detail, but the few following examples should prove enlightening.

Let's say you saw the country slipping into recession and wanted to sell, getting out of the market at the economy's peak. If you correctly identified that peak over the nine most recent recessions ending in 2001, your average return for the twelve months following each peak was 7.3%. Not bad, although it's below the market's historic annual average gain of around 11%. But you could have done better!

If you waited for six months past the peak before getting out, your average annual return for the next 12 months was 23.9%. That's more than double the average.

How about getting back into the market as we headed out of a recession? If you bought in at the trough—the low point of the economy—your average return for 12 months following was 17.6%. Very good. But if you got back in six months before the trough—while the economy was still heading down—your average return for the following 12 months was 27.8%. Much better!

This, I grant you, doesn't seem logical. But it is. Here's the explanation.

Eyeing the Future
In the aggregate, investors certainly pay attention to how the economy is doing today. However, they buy and sell based on how they think it will do tomorrow—or more accurately, over the coming months. Anticipating a downturn in the future, they sell well before they think the economy has peaked. As a result, the market usually falls well before the economy does.

Conversely, they buy well before the economy hits bottom based on expectations of a rebound and a brighter future. That's why the market generally bounces back before the economy does.

The Anti-antacid Approach
If I've learned one thing during my decades of research, it's this: No one can precisely time the economy or the market. Not you. Not me. Not anyone. If we react to prevailing recession indicators, such as rising unemployment and declining profits, we're just as likely to exit and enter late. We'll suffer the downside before getting out and miss the upside before getting back in. In tough economic times such behavior is understandable. Unfortunately, it damages our investment performance.

So what's an investor to do? Make a plan and stick with it. Good financial planning takes into account the long-term ups and downs of the economy and the market. Your plan can keep you from taking drastic, and possibly disastrous, steps.

Then, maintain a steady course. Understand that equities' average annual return of 11% beats inflation handily and builds a nice portfolio for your later years.

Finally, there's a big upside to not being able to time the economy—and not wanting to. With a plan in place and ignoring as much of the scary or euphoric news as possible, you may be able to sleep more soundly while other investors stay awake trying to figure out their next nerve-wracking move.
