Study Says World's Stocks Controlled by Select Few (InsideScience.org)
"You start off with these huge national networks that are really big, quite dense," Glattfelder said. “From that you're able to ... unveil the important structure in this original big network. You then realize most of the network isn't at all important."
The most pared-down backbones exist in Anglo-Saxon countries, including the U.S., Australia, and the U.K. Paradoxically; these same countries are considered by economists to have the most widely-held stocks in the world, with ownership of companies tending to be spread out among many investors. But while each American company may link to many owners, Glattfelder and Battiston's analysis found that the owners varied little from stock to stock, meaning that comparatively few hands are holding the reins of the entire market.
“If you would look at this locally, it's always distributed,” Glattfelder said. “If you then look at who is at the end of these links, you find that it's the same guys, [which] is not something you'd expect from the local view.”
