Hi,

does anyone know of any online resource that can show the top 20 % ownership of a share?

Right now I'm just manully going to the annual reports of every company and I'd like a less labour intensive way to screen for tightly held registers.

My conviction that a tightly held register can be a great indicator of volatility was confirmed today with NCL. T20 own 98%!

I'd like to start a strategy of patiently buying stocks like this.

Any pointers appreciated,
