Must have had to clear them by the end of the tax year, they would have made a load more money by selling in small chunks and not destroyed the SP. unless they�re planning on buying a load more at the lower SP
If MM�s were working a big sell the spread would be smaller to encourage buyers. If the MM�s are trying to work a big buy they�ll try to scare people into selling and keep the spread huge to put off buyers.
Always positive or negative options, either BOD are quiet because the company is in trouble financially or there�s something positive they can�t disclose. Not seen a share drop like this for no apparent reason before.
