Mns's be very careful in posting or expecting a share price jump on the 19th due to "funds having to buy in". I can tell you with 99% certainty it won't happen. It may go up but while funds may have to hold a percentage of the asx 300 for example. Non will just buy in on volume because a certain share has entered. The majority of any funds holding will be in the top 20 of say the asx 300 and filter down to none at the bottom of the asx 300.
Don't get me wrong it's excellent mns has been included just don't expect rockets or buy based solely on that new info.
