Do not fear, citizen: it was not a rational response to the unsustainable government spending and underfunded pensions in Greece and throughout the world, including the United States and its component state and municipal governments, that triggered the Dow Jones’ plunge yesterday.
Instead, it was a computer glitch or typographical error that, for a time being, looked as though it was going to bring economic collapse upon us. That is, it was something completely accidental, random, and out of your control which wreaked havoc with investor confidence and, potentially, your life’s savings.
Carry on as you were.
I prefer a diverse investment portfolio of canned goods, ammunition, and whiskey.
