ASX300 index rebalance March 2018, page-11

Yes, Cheapy, right at the start of that article that I put in in the last comment there is a list of all the major Australian share indices and you can click on all of them and see the shares in each article. The Major ones like ASX 200 have companies changed every quarter. On the day that they make the change the companies that are pulled out of the indices tend to get sold down and the companies going into the quarter get bought and it is interesting to watch the auction on that day. It is the 19th of March this time.
