Neat visualization, but as the website itself notes at the bottom (in fine print): "Correlation doesn't necessarily mean causation. Be careful when using correlations to draw causal inferences for trading or research."
Here's another fun tool where you can correlate search activity by drawing an arbitrary time series: https://www.google.com/trends/correlate/draw?p=us https://www.google.com/trends/correlate/draw?p=us
- pranade 13y agoExactly. gotta read the fine print :) We think this could get more interesting with time though. It was really cool when we got our first couple days of data and were able to see the basic principles of economics at work by looking at the anti-correlation of supply with price!

- throwaway13qf85 13y agoWhen you lose money for two weeks straight, it's nice to be able to figure out if it's a statistical blip, or if there's a fundamental reason that the trade stopped working. If all you have is a statistical correlation, you can't do that, and you have to guess. If you have a causal relationship in mind, you can examine the market to see if there are reasons to believe that the causal relationship might have broken down.
