Notice that 50% of company is now held by 4 people/groups with the biggest newbie being Hunter Hall Investment Management Limited with 18%.
There are a couple of other companies, GJT & SFH for example that have had sudden interest from new investors all of which ramp up to the 15-20% mark very quickly.
Have to wonder if people are taking advantage of the cheap share price and either setting up a blocking vote or preparing for a takeover play.
