Quote from TheStudent:
It's a meaningless figure since it is based on $600 trillion of underlying asset value.
It has no meaning on the potential exposure of the market : If I sell puts on $1mm of IBM, I buy calls on $1mm of IBM at the same strike - we get $2mm of derivatives. But really it's the same exposure as being long only $1mm of IBM.
It also has no meaning on the market value of the traded volume. A put on ABC struck at $0.01 when ABC is trading at $100 is worth about zero, but if I buy 100 of those puts, I have traded $1mm of underlying asset value but nearly zero of market value.
Exactly. Most of these stories are written by the same reporters who had the Katrina death toll at 50,000.
