The research was focused on assessing the companies listed on the ASX with their sector area and financial information. It was established that most of the companies listed on the ASX were from the material sector, although about 52.00% were either suspended or delisted. All the continuous variables in the sample data were highly positively skewed. The analysis indicated that the sample data used could not estimate the population parameter for the total asset for all companies that are trading. However, the sample could estimate the population parameter for the total revenue for the GICS sector of material only. It was found that total revenue for financial (GICS) is not more than the average total revenue for Health Care (GICS) and the average market capitalization, for financial and materials, did not differ. Lastly, it was found that there a significant relationship between net profit after tax and total assets.
