Web traffic represents a powerful mirror for various real-world phenomena. For example, it was shown that web search volumes have a positive correlation with stock trading volumes and with the sentiment of investors. Our hypothesis is that user browsing behavior on a domain-specific portal is a better predictor of user intent than web searches.
With the observation that equity analysts tend to cover similar stocks, we propose a simple, intuitive method to convert their coverage sets into pairwise similarity values among stocks. These values are shown to have a strong positive relationship with future stock-return correlation. Further, these values are easily combined with historical correlation. Together, they produce more accurate predictions...
