jobs, capacity utilization, GDP, wages, Unemployment, consumer confidence, retail sales - the list of economic indicators more important than the Dow goes on and on.
Also, the Dow itself isn't very useful as a market indicator - it's a dollar weighted index of 30 stocks. The S&P 500 and the NASDAQ composite are much more useful indicators of than the Dow.
My one worry since I'm disabled don't mess with my social security or Medicare.
