Simon been looking back on this one. On Friday the matrix was at about 14c when the share traded between 4320 and 4180 (middel ground of about 4250). After close the matrix changed and the same range but was 12c. Then Monday morning when share was ex div the matrix again changed to be on 10c for same price (4250). My question is as there were no major changes in gearing/delta etc, I know exercise price change ex div etc., but was there not a double input of data to move the matrix so far in the time frame? Maybe someone (the computer) changed the matrix after close friday to reflect Monday ex div and monday morning manual intervetion changed the matrix again ex div? Could you look into this for me. I am just interested in what the changes were as i cannot see them on B&S model either. Maybe I am missing something.
