Him fox buys another 70,000 shares - 140,000 or $300,000 in past week

As far as I can find jim fox has never bought any bta shares out of his own pocket - assuming he must be planning to exit the board sooner rather than later based on the shame he must feel (lol! ) I find it interesting he has all of a sudden decided to buy up big after years of nothing ? In a situation such as this it would normally be a show of support from a director to a company in a tough period nut as jim has never bothered about communicating anything of substance to shareholders I doubt he has bought the shares to make a statement ? I wonder if he smells a bottom and has decided to take a big bite!!
