Why does the stock market often tank when there's good economic news reported? Well, it's usually related to interest rates. Alan Greenspan and his buddies at the Federal Reserve set interest rates, trying to keep inflation at bay and promote a healthy economic environment. When positive economic news is released, such as lower unemployment figures, rising wages, or growing national productivity, the specter of possible inflation is raised. Economies growing too quickly can spur inflation, with too much currency in the marketplace leading to the weakening of the dollar and rising prices.
To stem inflation, the Fed notches up interest rates to decrease the amount of borrowing and slow down the economy. Rising interest rates render bonds more attractive, as they offer fixed incomes. Investors pull money back from stocks, which are hit doubly with the threat of shrinking corporate earnings and with the attractiveness of growing bond yields.
Got that? Maybe reread it once or twice. It's a bit complicated and can hurt your head until it sinks in.
Here's the Fool scoop on Greenspan and the Federal Reserve, and info from the horse's mouth itself, the Fed.
