Spiffy! A buddy and I have been working on a similar thing (not open sourced (yet?)) for a while off and on. The model we're going to shoot for is to look at online opinion on the stock as a base for estimating rise/fall.

Derwent Capital Markets (website down now) tried to do this with twitter, but ultimately collapsed:

Interesting. The venturebeat story suggests that the strategy works, but the company's web presence is dead. Hmm.

Reminds me of an article I read awhile back that pointed out a correlation between news about Anne Hathaway and an increase in Berkshire Hathaway stock.

Since stock prices are all about speculation and market psychology, it is an interesting approach. I'd be very interested to know about how you implement.

How do you define and track the "online" world though?

Wink wink, nudge nudge, that's the secret sauce. ;-)

But more seriously, the plan of attack right now is just to scrape newsfeeds from news sources via rss.

While of course this is susceptible to bias in the media, my hypothesis is that so are the stocks. A rising tide lifts all ships as has been said: so long as you buy lowish and sell highish you'll do all right[1]

Other routes might be:

- twitter

- stock trading forums

- industry news sites

[1] bear markets demand some kind of shorting strategy I believe.
