As to the question of whether Google could exploit their search data to predict the stock market: http://messymatters.com/searchpred http://messymatters.com/searchpred (summary: not really)
- wdewind 16y agoSlightly less short summary: In some things search can add a slight benefit to predictive analysis (from the current baseline strategy), in others it doesn't really help at all and even in the cases it does it's only marginally useful, "we find search volume on its own is predictive of future outcomes, but search is nevertheless outperformed by baseline models trained on publicly available data; combining search and baseline models generally leads to modest improvements."
