If you own iShares Core S&P/ASX 200 ETF (ASX: IOZ), the stocks you are invested in are about to change.

S&P Dow Jones Indices has announced the December quarter rebalance, which will become effective on 22 December.

Every quarter, S&P Dow Jones rebalances the ASX indices to ensure they accurately rank our largest stocks by market capitalisation.

Indices play an important role in enabling us to monitor and measure the market's performance over time.

The IOZ ETF seeks to track the performance of the ASX 200 before fees.

This means that every time S&P Dow Jones changes the composition of the ASX 200, BlackRock must adjust its IOZ ETF portfolio.

At the next rebalance, six companies will ascend into the ASX 200.

IOZ investors will gain exposure to three additional gold mining shares.

They are Ora Banda Mining Ltd (ASX: OBM), Pantoro Gold Ltd (ASX: PNR) and Resolute Mining Ltd (ASX: RSG) shares.

IOZ unit holders will also become invested in Canadian uranium miner, Nexgen Energy (Canada) CDI (ASX: NXG), telco share Aussie Broadband Ltd (ASX: ABB), and nuclear technology developer, Silex Systems Ltd (ASX: SLX) from the industrials sector.

The next rebalance will also see six ASX 200 shares exit the index.

They include the suspended ASX 200 travel share Corporate Travel Management Ltd (ASX: CTD), which hasn't traded since August.

Corporate Travel Management shares were suspended at the company's request after it disclosed accounting problems with its UK operations. Auditors have since uncovered incorrect revenue recognition of GBP 45.4 million and other irregularities.

If you own IOZ ETF, you will also lose exposure to uranium miner Boss Energy Ltd (ASX: BOE) and car parts retailer Bapcor Ltd (ASX: BAP).

Also exiting the ASX 200 will be poultry producer Inghams Group Ltd (ASX: ING).

Alternative asset manager, HMC Capital Ltd (ASX: HMC), and intellectual property services firm, IPH Ltd (ASX: IPH) will also go.
