depends if it was the company that bought them or a director;
but either way, it could be good or bad.
If the Director is buying them, he may see good value in the firm. He may be under pressure to send a calming message toexisting shareholders (despite the value of the shares), or he may be exercising some options he has earned in order to cash out. Pretty difficult to tell without a sound understanding of the firm.
If the company is buying its own shares.... may be it has a stack load of spare cash (bad), maybe it is trying to up it's tier 1 ratio, maybe it is trying to defend itself from a hostile - again, very difficult to tell.
