My understanding is that, similar to other indexes globally, a company officially becomes part of an index on or after a rebalance date. At that point, or closely before, tracker funds will begin to buy in to those entering and sell those leaving. The bottom of the index is likely to change daily - the tracker funds aren't selling the company that has gone from 298 to 302 - as it may well jump back in a few days later.
There is currently one Exchange Traded Funds (ETF) that tracks the performance of the S&P/ASX 300: Vanguard Australian Shares Index (VAS) . As at Feb 28th it didn't hold any shares in EMR (note - it has a holding in 309 companies)
