My friend and erstwhile co-worker Nabeel is getting deep into the Google Map hacking these days, and for his latest trick he’s come up with a real winner. His GeoIndex tool takes the stock performance for each company in the S&P 500 and puts it onto a map of the US. Little green and red arrows tell you if the stock went up or down for the day. Click on a company ticker or location, and you get a nice little in-place five-day chart. I found this moderately interesting until I realized I could click on industries too. So for today, I see that Pfizer had a bad day (not so surprising these days). But a click on “Pharm/Biotech” shows me that most of the pharmas also had an off day. I can also see the geographic distribution of companies: the big East Coast pharmas clustered around New Jersey went down, but the younger West Coast biotechs in San Diego and San Francisco did well on the whole.
I don’t know if it will help me make money, but it’s fun to look at.
He must be expecting some company pretty soon, because he’s got the place decked out with Google Ads. I can’t blame him: one mention on SlashDot will send his bandwidth bills skyrocketing.

Thanks for the blog :) GeoIndex did get mentioned in a Fool.com article, which I though was really cool. Bring on the visitors, my bandwidth is ready!
