Are seasonal anomalies real? A ninety-year perspective

This study uses 90 years of daily data on the Dow Jones IndustrialAverage to test for the existence of persistent seasonal patternsin the rates of return. Methodological issues regarding seasonalitytests are considered. We find evidence of persistently anomalousreturns around the turn of the week, around the turn of themonth, around the turn of the year, and around holidays.     

Volume and turn-of-the-year behavior

This paper studies the trading characteristics of listed companies by size, and year-end behavior. There were no transactions on nearly 25% of the days for the smallest decile even at the turn of year which is an active trading period for small companies. As a result of low levels of trading and the regulations governing exchange specialists, transaction prices and quotations of small listed companies may require several days to fully reflect equilibrium price changes. The data confirm the existence of a year-end seasonal pattern in rates of return for small companies and suggest that there may be a seasonal pattern for large companies as well.     

A Maturity‐level Assessment of Generalised Audit Software: Internal Audit Functions in Australia

The advancement of information technology in today's technologically driven era has had a significant impact on the way corporate organisations are conducting their business, especially in a developed country such as Australia. Consequently, it is now almost impossible to conduct effective and efficient audits without the use of technology‐based tools in control environments that are dominated by big data and increasing volumes of electronic audit evidence. Generalised Audit Software (GAS) is one of the most frequently used technology‐based tools available for the internal audit function for tests of controls purposes. The objective of this article is to explore the maturity of the use of GAS by internal audit functions in Australia. The literature review reveals that the use of GAS by internal audit functions globally is still at a relatively low level of maturity, despite the increased adoption of information technology and the generation of big data within organisations. Similarly, the empirical results also confirm the low level of maturity in the use of GAS by internal audit functions in Australia. Only 17.4% of the respondents displayed a high level of maturity with regard to the use of GAS.
