Evoi: Social media for financial markets

I came across Evoi in the unnecessarily good London free newspaper City A.M. Jessica Mead wrote a piece about it in the edition of 22 January 2009, interviewing director Martin Hollands. The article explains that Evoi lets financial market traders see other traders' positions and publish their own if they want.

This is interesting because it's bringing a sense of the old open outcry market back to financial trading. Hollands says: “You are getting a real feel for real trades”.

And Mead says: “Algorithms might be the name of the game in the big investment banks, but for the smaller players, getting an idea of what traders are actually doing, rather than what they say they are doing, is immensely helpful and arguably levels the playing field a little.”

Doctrine tells us that markets are, in themselves, information systems. The price of a stock or a commodity supposedly encapsulates all that is known about its standing and performance characteristics. Therefore traders should be able to take decisions simply by responding to price movements. And algorithms – computer models and programmed trades – can do that for them.

Evoi call the information in its community “flow”. Users can watch what other traders do, and follow their lead if they want to. They can benchmark themselves, and improve their consistency. They can also shield themselves from the misinformation that's layered into financial markets even though, officially, it isn't.

This is the first example I've seen of social media adapted for the financial domain. But if social media belongs in any commercial context, it belongs here. Reclaiming the trading activity for traders has got to be a good thing: I'd trust the herd instincts of frontline traders over backroom analysts any day. I can imagine that becoming a leader in the Evoi world is a position of some status, too – not one that could be earned easily, or held on to without sustained performance. And that means, ultimately, the trust of the community.
