Crises in financial markets affect humans worldwide. Detailed market data on trading decisions reflect some of the complex human behavior that has led to these crises. We show that massive new data sources resulting from human interaction with the Internet offer a different perspective on the behavior of market participants in periods before large market movements. Analyzing Google query volumes for search terms related to finance, we find that we can identify early warning signs of stock market moves. We further demonstrate that a trading strategy based on our analysis can outperform the market. Our results illustrate the unprecedented potential that combining extensive behavioral data sets offers for a better understanding of collective human behavior.
