It's this: Corporate earnings reports and broader indicators like employment numbers are often used as guides to where the whole economy is going, which can be a big mistake right now. These numbers are never terribly good guides in isolation, because by the time they show trouble, it's probably too late to react. However, they can be even more misleading than usual at times - like right now - when there's a significant chance of a U.S. recession. The two-part survey method in the U.S. works fine most of the time, but history suggests that when there's a major change in the trend of economic activity, the household survey does a much better job of picking it up, suggests David Rosenberg, an economist with Merrill Lynch. And as it happens, the household survey, which typically shows the same broad trend as the employer survey, is now showing a much gloomier picture: with an average job loss of 18,000 per month since July compared with the average gain of 112,000 in the official number out of the employer survey.The only reason that the unemployment rate didn't rise in October is that, in a very unusual development for a healthy economy, 211,000 workers dropped out of the U.S. job market. As well, notes Ian Shepherdson of High Frequency Economics, the employer survey can't pick up on jobs at newly created companies that aren't yet included, so these numbers must be estimated. He worries that this monthly estimate seems not to be responding much to the slowdown in the economy, so it could be helping to produce an unrealistically rosy total job number. This is all pretty technical stuff, but it serves to remind us of something that's not hard at all to understand: It's relatively easy to extrapolate the future when nothing big is changing. But when some important parts of the economy are in turmoil, forecasting - or even measuring what happened last month - becomes less accurate than usual. That's when its a good idea for investors to be especially cautious. jbryan@thegazette.canwest.com
