don't get so worked up (unless you're on margin). it's normal to have a correction, the question is where the bootom is? but mid to long term this a great buying opportunity. there is no question the economy is moving up albeit slowly, corporate profits are rising sharply it's normal in such a scenario that corporations will take the plunge and start hiring.
What your seeing is panic selling, the markets are oversold.
as warren buffet says "be greedy when others are fearful and fearful when others are greedy".
