Day of the week anomaly (Monday Effect) – How to do it?
Day of the week anomaly or more known as Monday Effect is one of calendar anomalies in financial market. It states that the stock market returns on Monday is significantly different from other day. This anomaly is proposed by Kenneth French in 1980, and his research paper was published in Journal of Financial Economics. The appearance of Monday Effect is an evidence of market inefficiency. Yet, in French (1980) paper, he suggested an arbitrage profit or mispricing profit from this anomaly. He further surmises “Although an active trading strategy based on the negative expected returns would not have been profitable because of transactions costs, investors could have Increased their expected returns by altering the timing of trades which would have been made anyway – delaying purchases for Thursday Friday until sales scheduled Monday on preceding Friday”

Heteroscedasticity in SPSS
Hi! One of the test for CLRM assumption is Heteroscedasticity. Testing it in E-views or Stata for Time-Series or Panel data is easy because the software provides the command. You just need to click this and that, then the heteroscedasticity will be out. However, testing it under SPSS software (perhaps cross-sectional data) it needs a work.
Below is the process to run it. Note that you need to copy paste the macro syntax below to run it. We use Breusch-Pagan and Koenker Test for it. The procedure is as follow: Continue reading

Herding in financial Market: How to do it?
Remember a folk story about pied piper of Hamelin (https://en.wikipedia.org/wiki/Pied_Piper_of_Hamelin) ? Once upon a time, Hamelin town was full of rats.

Women on Board Effect: How to do it?
Women on Board research is an interesting research considering the issue of gender equality. However, the role of women in firms has not extensively and empirically discussed like other corporate governance issues. Research has found that women may change the board room situation because women are more cautious than male on board in corporate decisions making (Huang and Kisgen, 2013 and Levi et al., 2013). Laura Tyson, a former economic adviser to US President Bill Clinton, recommended the improvement of board diversity to increase firm’s financial performance through the number of women on board (Tyson, 2003). Adams and Ferreira (2009) studied 1500 companies at United States from 1996-2003, and found female directors have significant impact on corporate performance of firms with weak shareholders right. They stated that female directors are more likely to monitor their committees. As the greater the gender diversity, the directors have fewer attendance problem. Therefore, this issue should be explored more in the future

Temperature Effect: How to do it?
Weather effect is another interesting research in finance. It is actually an argument for the traditional finance that relies much on rational behavior assumption. So, whenever you write problem statement for this topic, start it with the argument on rational behavior. I firstly read paper of Saunders (1993) then followed by Dowling and Lucey (2005). It really attracted me. How come weather may affect stock price? Right?
Who support it? A lot! For example, Loewenstein (2000) argues that the emotions and feelings influence our decision making process. It may dictate our long-term cost and benefits, hence, it will affect the equity pricing. The logic is simple, when it is rainy day, we tend to feel lazy compared to bright day (we tend to be aggressive). This emotion may affect our decision making. If it is rainy day, we tend to have our leisure time, meanwhile, during sunny day we tend to be rushed out (Yet, this debatable even in psychology field). Continue reading
