Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Not if you labour under the delusion that volatility is just measurement noise, not a real effect of economic significance.

Volatility is noise, but not measurement noise :P

For any who think it is "just noise" I would suggest that they try standing within half a kilometer of the launch pad of the Space Shuttle--without ear protection, or, more mercifully, within a meter on axis of a large speaker array being swept with 1/3 octave noise at 130 dB SPL. Indeed, I have wondered how much of the electro-magnetic component of the Big Bang can be accounted for by 1/f noise. A large part of the detonation of a thermonuclear device is "just noise". Idiots.
