The mean return of all the three stocks has been negative in the period of 52 days. Also, the return of benchmark index ASX 200 is also negative in past one year. QAN is highly negative due to recession hit airline industry. WBC in terms of mean return had outperformed the benchmark index. This is due to the growth in banking industry in Australia. Similarly the standard deviation and variance shows WBC is the lowest risky stock among all the three securities. The market for regional banking and brokerage services is significantly competitive as it allows consumers to access financial products and compare interest rates and services from numerous financial institutions. Customers in this sector are always sensitive to competitive interest rate levels and services. Therefore, banks need to lure clients away from competitor banks by offering lower financing, preferred rates and investment services. Success in this sector lies in offering both the best and fastest services, but this also causes banks to experience a lower ROA. Hence, the company has to compete effectively for deposit, loan, and other clients in its markets in order to maintain its market share and growth. WBC primarily competes with larger financial institutions with greater financial resources, lending limits and larger office networks as well as a broader range of products and services. WBC in order to maintain its profit levels and remain in business must control its operating costs as well as credit and funding costs. Apart from this, rapid technological changes in the banking sector have also increased the level of competition with the introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to reduce costs and has also made it possible for non-financial institutions to offer products and services that have traditionally been offered by financial institutions, thereby increasing the competition further. Since WBC competes with larger financial institutions with greater resources, it faces the threat as the peers would be in a better position to invest their resources for technological advancement and gaining an edge over others in terms of better products and services.
