Yesterday the NYT’s David Leonhardt wrote an interesting piece covering new research from Christopher Malloy of London Business School, Andrea Frazzini from University of Chicago, and Lauren Cohen of Yale. Entitled “The Small World of Investing: Board Connections and Mutual Fund Returns,” the research basically finds that mutual fund managers are more likely to buy stocks and take larger positions in companies that are in their academic network. Further, these money managers perform substantially better than funds that dont buy stocks in their network.

The data:

Yowza! Over 8% per annum difference! These guys beat themselves up for small fractions of a single percentage point return.

The authors conclude thats its either insider trading, ease of information gathering by being in the network, and better manager selection by investors due to network relationships. Intuitively all seem correct but the split is, of course, the rub. (I blog about this some more here.)

So I find this really interesting because it assigns dollars to the value of networking. We all know its important but who would of though that the difference was so large? Sure some of this data includes illegal activity but I think we now have a solid benchmark of networkings value. How does 70% more money sound to you? Its easy to see why social networking sites have been all the rage and why it is imperitive that all you old-schoolers who think your physical network is all you need, need to think again - especially if you are selling lofts to hipsters and not mansions to grand ma. Come on, get connected and get rich!
