Indeed, it is important to remember that correlation does not imply causation. I also think that this service is supposed to find events that cause searches, not the other way around.

Perhaps if you move the dates around a bit (i.e. push the dates of stock closing prices back a day or two) it could find some real correlations of news items about IBM causing searches about related issues, but I can't imagine a straight relation between _the volume_ of searches and the stock price. Any event, good or bad, will cause a rise in volume of searches. Perhaps you should try to correlate the volume of trading stock, not the closing prices.

I haven't checked by doing a proof of concept, but I think you can probably pull the Google Finance data directly into a Google spreadsheet using the =googlefinance() formula?


I'm agree w/ Michał Tatarynowicz's opinion.
