Blue (I'm one too by the way) - I was looking at the London Stock Exchange website where it is showing 87/91.
The spread they show is usually between 1.5 and 2.5p, but today has widened to 4. Isn't this effectively discouraging buyers? and if that is so does this indicate the MM's are short of stock?
Another curious thing is that the 'Price' is usually the midpoint between bid and offer which should be 89, but it ‘aint?
Maybe it’s nothing more than a input person who had a long Christmas lunch but it made me wonder.
