Looking for meaning in financial markets is like looking for patterns in a violent sea. The information that emerges is the product of buying and selling by people, with all their contradictions. Prices reflect a mix of emotion, biases and cold-eyed calculation. Yet taken together markets express something about both the mood of investors and the temper of the times. The most commonly ascribed signal is complacency. Dangers are often ignored until too late. However, the dominant mood in markets today, as it has been for much of the past decade, is not complacency but anxiety. And it is deepening by the day.
