ASX Top 20 Companies

The S&P/ASX 20 (XTL) is Australia’s narrowest stock market index.

The index contains the 20 largest ASX listed stocks and accounts for ~47% (March 2017) of Australia’s sharemarket capitalisation. All companies are highly liquid and considered “bluechip” shares.

The ASX top 20 companies offer little diversification with only 8 GICS Sectors represented. The Financials sector holds four of the five largest companies and accounts for ~46% (March 2017) of the index.

There’s currently one Exchange Traded Fund (ETF) that tracks the performance of the index: iShares S&P/ASX 20 (ILC).

The best website is Market Index.
They have current ASX share prices, company charts and announcements, dividend data, directors’ transactions and broker consensus.


How are ASX 20 companies selected?

Constituents are selected by a committee from Standard & Poor’s (S&P) and the Australian Securities Exchange (ASX).

All companies listed on the Australian Securities Exchange (ASX) are ranked by market capitalisation. Exchange traded funds (ETFs) and Listed Investment Companies (LICs) are ignored. The top 20 ASX stocks that meet minimum volume and investment benchmarks then become eligible for inclusion in the index.

Rebalances are conducted quarterly in March, June, September and December. If a significant event occurs (e.g. delisting, merger, etc.) an intra-quarter rebalance may be conducted. A minimum of two business days’ notice is given to the market.
