There are many factors influencing the stock market, these include events as unimagined as sports and even obvious ones such as war. Generally, there is a relationship between change in stock prices and investor sentiment. This is as demonstrated by Guy Kaplanski and Levi in their paper on “Exploitable Predictable Irrationality” taking into account the FIFA world cup event.( Kaplanski & Levi. 2010. Pp 535-553)
In the paper, the writers argue that losing and winning often shift the investor sentiment, which in the end affect their investment decisions. Naturally, there is only a single winner out of every football match encounter and therefore after every game the stock market gets affected.
To investigate this hypothesis, an ideal neutral market is chosen, in this case the US stock market. This is due to its versatility of global investors and therefore all the games played in the world cup are likely to affect it. In their findings, a conclusion that losing affects the stock market negatively whereas the effect of winning is negligible.
One of the main hypotheses is that losing instigates a negative effect by the fans whose countries lose. To test this, three methods are employed, i.e.:
In brief, the paper focuses on sentimental influence on the investment decisions made by investors. Not only on local stock markets but also on international markets.
The major points drawn include:
Several scholars have carried out research in order to answer the question of whether there is a relationship between investor sentiment and investments. There have been a number of researches conducted such as:
All these articles and many others seek to answer the same question as that rose in the research. It is therefore important to determine the factors that influence the investor decision since it is through this that the market may be modeled for prediction. Interestingly, games are among instigators for sentiments, this is due to the loyalty attached to a particular team and even more the spirit of nationalism. Therefore, the research question is important in contributing to the learning of the mindset of the investor in relation to stock returns.
The research process is designed into six sections, each covering a specific aspect to consolidate the whole research process, i.e.:
The study design is a standard research procedure; therefore, it captures most of the research aspects. However, inclusion of the areas into which the research features would improve the relevancy to the readers. I.e. explanation of the study context, hence it is sensible
The method on data analysis involves regression to determine the relationship presented among the data variables; which include:
The research involves multiple regressions i.e. Ri= Yo+ βXi + £I where R is the daily stock returns, Y correlation coefficient intercept and Xi are the independent variables robustness check and visual graphing, which is adequate to investigate multiple relations between interest variables and in carrying out data interpretation. This enables to establish the significant factors. The process of data analysis and output processing was done using Eview software.
Interestingly, despite the indirect relation between football and stock in America, the research pitches the economic specification to determine stock trends during world cup events. In the American stock market, this is because, according to the authors the fact that approximately a third of the companies quoted in the stock market are foreign and therefore the stock market is most likely to be influenced by foreign investor decisions. Therefore
In application of mathematics and statistics to economics, the authors set up an economic model used to show the effect of football sport during world cup events in a period after the Second World War and 2006. The model specification includes outliers so as to be realistic and in line with real life situation.
Model:
Ri= yo + 1iRi-1+ 2iDii+y3Hi + y4Ti + y5Pi+ y6Ei + 7iJii+ ?i
Where ( Rt =daily return,Y0= regression intercept coefficient, Rt-1, Rt-2 =
1st and 2nd preceding day returns, Dit , [1,2,3,4], are dummy days of the week: Monday, Tuesday, Wednesday, and Thursday,10 Ht is a dummy variable for days after a non-weekend holiday and Tt is a dummy for first five days of taxation year, Pt is a dummy variable for the world cup (June–July) event.) (Kaplanski & Levi, 2010. Pp 545).
The authors carry out a sensitivity analysis through:
Therefore, the researchers carry out adequate sensitivity analysis.
After testing the null hypothesis, carrying out analysis and interpretation of the output, the authors find a relationship between stock prices during the world cup events and the winning or losing of teams. Therefore, they conclude that the world cup effect is:
Such that the average return during the event is -2.58%, compared to normal days on the same period when returns average on +1.21%.
This conclusion is sensible and is important in determining when to buy and sell stocks as major sports events happen, it also suggests balancing on stocks bought to avoid bad losses during world cup event.
In analyzing the relationship between stock returns from value-weighted index and from equal weighted index, we use market data, having variables:
|
i. Dates ii. Stock returns( RVW- value weighted index, REW- equal weighted index) iii. Dummy days- ((D1,D2,D3,D4,D5-mon, Tue, wed, Thurs, Fri), H-dummy variable for days after non-weekend holiday, T-dummy days for 1st 5 taxation year days, E-event days, J-dummy for 10 days with highest returns(1= highest, 2=lowest), P-control variable |
The analysis involves ordinary least squares regression and ANOVA in R. Output is then generated as:

The conclusions drawn from the analysis include:
Economic theorists often argue that major multiregional boost local economies of the host countries, this includes:
This is suggested to be due to a gush in the economic activities connected to the event. (Ross. 2018) . Previous research shows that when a country wins an Olympic medal, national stock activity decreases (Jessica & Markellos, 2018).
The suggested reasons infer that games distract both the public and investors alike. The main hypothesis is that Olympic games affect the stock market of the host country and the international markets of other countries participating in the event. Our null hypothesis is that Olympic Games do not affect the stock market and that stock markets are independent of investor swayed sentiments.
The alternative hypothesis is that Olympic Games distract investors, where with every gold medal won, sales volume drop otherwise there is no effect in the sales. (Jessica & Markellos, 2018).
However, it is a topic of argument as to whether the Olympic Games affect attention or sentiments of the investors.
The dataset used is based on 4 summer Olympic Games):
Six of the eight countries that have hosted the Olympics since 1984 saw their stock market generate positive returns. (Kiran, 2016

From the output, we can conclude that:
This supports the survey done in London (2012) games that indicate; one out of four people listen or watch the event while at work (University of East Anglia, 2018).
Therefore, from the research analysis we conclude, major sports events affect the investor attention therefore affecting the stock volume sales.
