Techcrunch had good coverage of Wikinvest’s launch of embeddable, annotate-able, wiki-able charts. Wikinvest, which like it sounds, is a wiki focused on building out user-generated company and stock information. Now, the site has developed charts that can be annotated and embedded into websites and blogs.
If you check out Apple’s chart (sorry wordpress.com doesn’t allow posting of javascript) and click on ‘B’, you’ll see that on June 10th, Apple reported a new iPhone with GPS and 3G capabilities, better battery life and improved audio quality.
Or, on Amgen’s chart, you can click on ‘L’ and see someone’s explanation for a continued slide in the stock price (which he/she attributed to a potential safety risk for Aranesp)
Google Finance has charts that attempt to pair up news events with movements in the stock price. While it’s a really interesting cause-effect, Google Finance unfortunately doesn’t capture the news or information that is affecting stock price movement. I attribute this to 2 reasons: 1) Sometimes it’s just impossible to explain price movement (sorry, financial commentators) 2) Google’s news set is in some cases unexplicable weird and picks up stories that seemingly have little impact.
Anyway, these charts powered by wikinvest are interesting for financial bloggers and may ultimately do a good job of providing numerous opinions as to what’s affecting individualk stocks at any given moment. It would be very interesting for someone to look into the accuracy of wikinvest’s annotated charts and provide some metrics at some point (if this is possible to track). If anything, these charts improve on Google’s charts (which I happen to like) by overlaying wiki-like UGC on top of stock charts.
