I went back and had a look when the last sale of director's shares happened. It was on the 8th & 11th of August 2010, which was approximately 2 months after the "Base Metal Demerger" announcement. At that time the share price reached a high of 96.5c on high volume, but I can't tell you if that was the price one of the directors received on the sale of some of his shares.
To put things in perpective, three directors companies redeemed 1,392,540 20c listed options with a 29/3/13 expiry date. Between them they added $278,508 to THX's coffers. Two of those directors still hold all their FPO shares including the ones from the option redemption. The 3rd director's company (Ragged Range Mining Pty Ltd)redeemed 982,560 options and then sold a further 1,282,440 FPO shares (9.07% of his original FPO holding) Maybe Mr Crabb was intending to buy a reasonable stake in the Base Metal company, and of special importance was the consideration that the options were unlikely to be eligible for preference in the "Base Metal Demerger"
I hold a small number of shares in THX, I dont know any of the directors or staff, but I do think balance of opinion is important, especially when they are getting some flak. Merv
