Market sheds $21 billion

Market sheds $21 billion : "On commodities a barrel of West Texas crude oil was fetching $US73.36 and spot gold was trading at $US664 an ounce."

47 billion gone yesterday and 21 billion gone today. So where has it gone? It doesn't just vaporise and if we are pegged to the American dollar then well, yes...billions are just going to vaporise if they are unstable financially. So how does that tip the whole world market but the oil and gold prices are going up...even Bunning's shares? I gather if you know what you are doing there is a lot of money to be made on this roller coaster ride and it would be a good time to buy shares because you'll get them at low prices and they might bottom out but a good share is a good share and will recover. Do you have the money and the intestinal fortitude to ride it out? Meantime small investors are bought out...and Qantas has made a 50% annual profit. I'd really like someone who knows what they are talking about explain all of this.
