The ASX 20 is home to the 20 largest listed companies on the Australian share market and will welcome payments company Afterpay Ltd (ASX: APT). The buy now pay later provider will take the place of insurance giant Insurance Australia Group Ltd (ASX: IAG).

ASX 50.

Afterpay is also being added to the ASX 50 at the rebalance and will be joined by cloud-based business and accounting software provider Xero Limited (ASX: XRO). They will be replacing energy producer Oil Search Ltd (ASX: OSH) and retail property company Vicinity Centres (ASX: VCX).

Finally, the ASX 200 will be welcoming online retailer Kogan.com Ltd (ASX: KGN) and plumbing parts company Reece Ltd (ASX: REH) at the open of trading on December 21. They will actually be replacing three shares in the index. This is due to the ASX 200 currently containing 201 shares following the Deterra Royalties Ltd (ASX: DRR) demerger from Iluka. Leaving the benchmark index are Avita Therapeutics Inc (ASX: AVH), Cooper Energy Ltd (ASX: COE), and Western Areas Ltd (ASX: WSA).

What now?

As fund managers often have strict mandates in relation to the shares they can buy, this news could give certain shares a boost and put pressure on others.

In addition to this, index-tracking funds will be needing to buy the additions and dump the removed shares from each respective index in the near future. This could also add pressure to the buy and sell sides, depending on the share.
