Shareholders call for Fox buyback 21ST Century Fox expects to complete the delisting of its shares from Australia by May 8 as retail shareholders joined calls for the company to launch a buyback for local investors. The US-based film and pay-TV business plans to hold a meeting in New York on March 21 to vote on the proposal, which would result in share trading being concentrated on the NASDAQ market in the US, where most of the business is based.
