Blue Ridge is the only seller, just like one year ago Federated Investors Inc was the.
It does not matter BR sells their full or part of their position. Once they stop selling, this stock will move up dramatically. Remember FII sold out at $1.7x last year, and the PPs more than doubled early this year.
perhaps coordination with external investors? When EI stake sold awhile back, wasn't there some process where the shares were absorbed without tanking the price? I think the close in folks at XIN on the US side are "tiger cubs" --- would have long relationships with big money in US from the original fund / relationships.
