Data Integrity

July 31, 2009

One of the reasons that we are fond of using price as an input to calculate relative strength is not it does not rely on forecasting and is not subject to revision. If you subscribe to the “garbage in, garbage out” school of thought as we do, having reliable data is somewhere near the top of your wish list.

Fundamental analysts often forecast earnings for their valuation models, which creates another set of complication to getting things right. Economists, on the other hand, often have to deal with data that is revised after the fact. The Commerce Department recently revised U.S. GDP data going all the way back to 1929! (Click here for Eddy Elfenbein’s hilarious take on the data revisions.)

This just seems ridiculous to me. Pity the poor economists. It is no wonder that economic forecasting is so difficult with data like this! It brings to mind the old saying that the only function of economists is to make weather forecasters look good.


Money Still in the Till

July 31, 2009

Last fall and early this year, the financial crisis seemed exceedingly dire. Governments and citizens across the globe felt as if the entire commerce and banking system might implode. So governments rode to the rescue and pledged to bail out various banks and financial institutions, along with providing all sorts of related credit facilities and backstops.

According to the International Monetary Fund, it turns out that governments have only had to spend about 40% of the money they pledged so far. It’s a good thing that governments haven’t spent all the money, by the way. The forecast for the pile up of debt in industrialized nations over the next five years is not pretty, and the massive U.S. share can’t be too helpful to the dollar.

The economic crisis may not have been as bad as believed, but in my view, it is more likely that financial institutions adapted very rapidly to the new environment and stemmed some of their own bleeding. Even big banks are not fond of going out of business or operating under government mandate. The government kick-start might have been necessary, but the healing has happened faster than anyone guessed.

The underlying problem may really be one of forecasting. Economists often make straight line forecasts—which would be accurate if no one reacted to the situation. An economist would probably forecast that you would drive your car off the road at every turn. You don’t, because each time a turn comes up you react by adjusting the steering wheel. Adaptation is a wonderful thing—and a necessary one, since forecasts can often be so far off the mark.
