There's been steady buying since just before Xmas. Pop up today looks to be MMs running up a short position since they don't have stock to cover the buys so far. Bid up to 1p and offer to 1.5p as MMs are running a 0.5p spread on their prices. MMs won't be able to cover their short position easily unless some more people sell soon. IMHO.
Reasons for the buying in the first place? That's a different matter, could be related to any of the following, imho:
- news on legal claim
- franchise news
- other 'deal' news.
