Every quarter the S&P Dow Jones Indices group adjust or rebalance their indices.
For example the S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) index ranks the top 200 companies by size. The companies included in the top 200 must also be highly liquid and tradable.
In my opinion, watching which companies are added to the S&P/ASX 300 (Index: ^AXKO) (ASX: XKO) is a good pastime. That's because it can include the smaller, emerging, companies listed on the ASX that you may not always notice.
Also, many of the largest fund managers (think superannuation funds, multinational asset managers, etc.) are prohibited from investing in companies smaller than those included in the S&P/ASX 300 for obvious reasons.
Therefore, when companies are added to the index, they can be bought by more money managers and index funds – making a stronger market for the company's shares.
