The smoother the road, the faster people are likely to drive. The faster they drive, the more excited they are about getting to their destination in good, if not record time; but, also, the greater the risk of an accident that could also harm other drivers, including those driving slower and more carefully.

That is an appropriate analogy for the way unusually low financial volatility influences positioning, asset allocation and market prospects. And it holds for both traders and investors.
