The dividend yield on shareholders' funds of Australia's top 120 companies for the week ended Friday 10 July 2009 is recorded in the data file.
1. Column 1 stores the dividend yield for the top 1-40 companies ranked by market capitalisation
2. Column 2 stores those for the top 41-80 companies and
3. Column 3 for the top 81-120 companies.
To understand the meaning of these yields, consider 3.43% yield that was realised on the first company's shares in 2008. This means that $ 100 invested in the shares of that company at the beginning of 2008 would have yielded a profit of $3.43 over the year, leaving you with a total of $103.43 at the year's end. The data is also available to you in an excel spread-sheet for your convenience.
