ABBREVIATIONS C4F: Cahart four-factor model CAL: Capital allocation line CAPM: Capital asset pricing model DDM: Dividend-discount model FF3F: Fama-French three-factor model GICS: Global Industry Classification Standard HML: High minus Low MPT: Modern portfolio theory SMB: Small minus Big ABSTRACT On the ground of a well-known Markowitz (1952)’s Modern Portfolio Theory, Sharpe (1964) and Lintner (1965) developed a specific relationship between risk and expected return, which has been named as the Sharpe-Lintner Capital Asset Pricing Model (CAPM) CAPM or the Sharpe-Lintner CAPM is a well-known and most widely used model for estimating a rate of return/cost of capital The CAPM confirms that only systematic risk – denoted by ß (beta), does matter and investors are only compensated for taking systematic risk Since its introduction, many studies have been conducted in an effort to assess the validity of the CAPM in practice Practitioners and regulators around the world including Australia, Germany, New Zealand and United Kingdom employed CAPM as a primary model to estimate asset’s return However, various studies demonstrated that CAPM appears to underestimate returns for low-beta assets and overestimate returns for high-beta assets The criticism went further as Fama and French (1992) introduced the three-factor model to estimate the asset’s return The Fama-French three-factor model has been proven to work well in the US market and that beta is alive in the American context However, in contrast to the US market, Vo (2015) argued that the Fama-French three-factor model has been proven to not work well in the Australian context A work by Savor and Wilson (2014) concluded that beta, or systematic risk, is still alive in the US market A similar question is that whether or not beta is still alive in Australia because Vo (2015) has never tested this hypothesis? We are not aware of any study on the issue which has been conducted This study is conducted to fill in the gap This study examines the validity of the Capital Asset Pricing Model (1965) in the context of Australia on the ground of the pioneering work by Savor and Wilson (2014) for the US The choice of Australia is important because, among all nations in the Asia-Pacific region, Australia is one of a few which has required data for the analysis to be conducted In the heart of the CAPM, beta is considered an important measure of systematic risk which is generally defined as an uncertainty about general economic conditions, such as GNP, interest rates, or inflation From that perspective, a key purpose of this study is to examine and quantify whether or not systematic risk is responsive on the days when macroeconomics news/events are announced or scheduled for announcement On the ground of Savor and Wilson (2014), four different types of portfolios are considered in this study including: (i) 10 beta-sorted portfolios; (ii) 10 idiosyncratic risk-sorted portfolios (iii) 25 Fama-French size and book-to-market portfolios; and (iv) industry portfolios In addition, macroeconomic events include announcements in relation to growth, inflation, employment, central bank announcements, bonds, housing, consumer surveys, business surveys and speeches from the Prime Minister or the Governor of the Reserve Bank of Australia Days with these events are allocated into the group (the so-called a-day) which is separated from the n-day (non-announcement days) group In addition, in this study, a sensitivity check, which is beyond Savor and Wilson (2014), by adopting different definition1 of the a-day group including (i) macroeconomics announcements which consist of news about growth, inflation, employment, Central Bank, bonds and speeches; (ii) microeconomics announcements which contains news related to housing, consumer survey and business survey; (iii) economics announcements which are basic news about news about growth, inflation, employment, housing, consumer surveys, business surveys and speeches; and (iv) financial announcements which are combined by news about Central Bank and bonds This study is conducted on a sample including more than 2,200 Australian listed firms collected from Bloomberg for the period from January 2007 to 31 December 2016 is employed As such, the total of nearly million observations has been used in this study Using the linear regression with panel-corrected standard errors method and Fama-Macbeth regression across various portfolios, two fundamental findings achieved from this study are as follows First, there is evidence supporting the presence of systematic risk in the Australian context Second, the above evidence may disappear when different portfolio formations and different definitions of macroeconomic events are adopted In summary, whether or not beta, or systematic risk, is alive in the Australian context depends on how portfolios are formed and macroeconomic events are classified These fundamental issues are generally known as puzzles in asset pricing studies and multi factor model has never been proven to withstand well when different markets/time/techniques are tested An appreciation to an anonymous reviewer who provides critical comments to the previous version of the paper which was presented at the Vietnam’s

of the Reserve Bank of Australia which is already mentioned to some groups This study classify nine of them into fours group: macro event-related group, micro event-related group, financial event-related group and economic event-related group Particularly, macro event-related group consists of news about growth, inflation, employment, Central Bank, bonds and speeches Micro event-related group is constructed from news about housing, consumer survey and business survey Financial event-related group contains news about Central Bank and bonds Economic event-related group is characterized by news about growth, inflation, employment, housing, consumer surveys, business surveys and speeches For each group, the results are installed in four tables The first two tables demonstrate result in which beta is estimated separately for a-day and n-day, so call conditional beta A claim “Yes” in the pooled regression row means that coefficient of βNi, t and βAi, t in the following model are different and βAi, t is significant Ri, t +1 – Rf, t + = α0 + γ1Dt + + γ2(1- Dt + 1)βNi, t + γ3Dt + 1βAi, t + µi, t + and vice versa A claim “Yes” in the Fama-Macbeth regression row means that coefficient of βNi, t and βAi, t in the following model are different and βAi, t is significant Although the independent variables - β - in two following equations are denoted differently in the surface, they all equal in value RAi, t+1 – RAf, t+1 = α0 + γ0βAi, t + µi, t+1 RNi, t+1 – RNf, t+1 = α0 + γ0βNi, t + µi, t+1 and vice versa 58 The next two tables are stemmed from estimating beta regardless types of day, so call common beta A claim “Yes” in the pooled regression row means that coefficient γ3Dt + is statistically significant different from zero Ri, t +1 – Rf, t + = α0 + γ1Dt + + γ2βi, t + γ3Dt + 1βi, t + µi, t + and vice versa A claim “Yes” in the Fama-Macbeth regression row means that coefficient of βNi, t and βAi, t in the following model are different and βAi, t is significant RAi, t+1 – RAf, t+1 = α0 + γ0βAi, t + µi, t+1 RNi, t+1 – RNf, t+1 = α0 + γ0βNi, t + µi, t+1 and vice versa 59 Macro event-related group – conditional beta Pooled regression Fama-Macbeth
