Love this seculation pre - date. Base on the closing price Dec 12th

Here is how I see it. ( at present)

Hays (89th) MK cap 2.2bn in no problem.BEST bet by far. LONG
BA(80) to drop share price leading to just geting in. NETURAL
Burberry (99) Tracker buying and pushing it to new hights and getting in. LONG
Mitchell & Butler (111) As before being bought on the day and only needs to get to 2.38p (up 5p) to get into 109 and for the committee discretion to keep it in. Very VERY rare that this commitee kicks a present FTSE 100 company out, it ALWAYS favours the present 100 member. LONG

Though there is less 100 tracker funds around more 200 / 250, the pure speclation and trackers buying to get early postions leads to rapid movement and momentum. HAYS is the one most likly to see % rise.
