My son has an upcoming assignment in Eco which is basically to compare and contrast two blue chip companies in the same sector: explain the industry, analyse the recent share price action based on fundamentals and evaluate which of the two would be better to add to a long-term investment portfolio based on fundamental criteria. He initially went for the obvious CBA/WBC, but took my advice that they were really quite similar and he may be better to find two companies with different trends. He's now thinking WES/WOW, but I reckon TLS/TPM or STO/WPL would be much easier to find differences in and be able to very clearly find differences in their major fundamental ratios. What do the experts think???
