Abstract
Making profit is the common goal for the most of investors. In order to make a decision
concerning investing in stock exchange, investors should deeply understand the factors that
determine the stock price. According to scholars, the stock price of a company tend to be
unstable, which lead investors to look for the elements that are influencing it in order to predict
its movement, consequently make a profitable investment decision. The factors that influence the
stock price can be either internal or external, and direct or indirect. The internal factors include
dividend, which is the cash payment that the stockholders receive, the market capital that is the
company’s value, the net income that is the total earning of the company, the earning per share,
the liquidity of the firm, the book value and the return on equity. The external factors could be
any change in the government policies, political issues, rules and regulations, the international
situation, the exchange rate and the media. In this study, we selected three internal factors that
could affect the stock price, which are the earning per share, the book value, and the return on
equity. After running different tests using the multiple regression analysis including T-test, F-test,
and Durbin Watson test, we found significant results as P-value < α, which would be interpreted
by the existence of a linear relationship between the independent variables (earning per share,
book value, and return on equity), and the dependent variable (stock price).

1. Introduction:
Many factors can cause the price of a stock to rise or fall; it could be from specific news
about a company’s earnings or a change in how investors feel about the stock market in general.
In our research, using the statistical tools learned in class we decided to demonstrate how the
stock price is influenced by other factors, particularly in Moroccan’s companies. In order to
choose our independent variables and before collecting data, our team has done some extensive
research to find out what are the appropriate factors that we can use for the research. We based
the search on other countries in order to see afterwards if the same factors could be applied to the
Moroccan context.
According to a study that was conducted in Malaysia, earning per share significantly affects
stock prices. The aim of the study was to determine the impact of the earning per share (EPS) on
stock prices of Public Banks located in Malaysia, and to measure the degree of stock prices’
response to changes in earning per share. The study indicated that EPS has a significant impact
on the movement of stock prices of the bank, and contributes significantly to the explanation of
long-term stock price variation. Hence, it is considered as one of the strongest factors to evaluate
the actual performance and the progress of a company since it reflects its financial situation.
In 1984, a researcher called Balakrishnan studied the impact of dividend per share, earning
per share, and book value and yield on share price of firms in India and his studies showed up
that the book value and dividend per share turned out to be the most valuable determinants of
market price in all firms studied. However, in our project dividend per share was not found in
many Moroccan companies while collecting data so we could not consider it as one of the
independent variables and only chose the book value. Moreover, in another study that AL
Khalaileh conducted in 2001; 40 Jordanian public firms were chosen as a sample for his study. Al
Khalaileh examined the link between accounting performance indicators and market ones. The
outcome showed an important optimistic relationship between the market price per share and the
ratios of return on assets and return on equity.

2. Data and Descriptive statistics:
Data:
To collect data in order to conduct our project, we have been searching in the Casablanca
Stock Exchange website, and we have retrieved a sample of 35 companies for the year 2014 after
erasing those with insufficient data. After a deep research in what are the factors that could
influence the stock price, we have found ourselves with only three main factors applicable in the
Moroccan context that are earning per share, book value, and return on equity. The sample size
is equal to 35, so the central limit theorem is applicable for this study and the population is
normally distributed.
Descriptive statistics:
First, we will analyze the data using descriptive analysis techniques.

After the analysis of the data, we should be able to conclude that earnings per share, book
value and return on equity positively affect the stock price of the companies that we selected for
the study.

Assumptions:
1st Assumption: Linearity.
Using SPSS and Excel, we plotted the independent variables, which are earnings per share
EPR, book value and return on equity ROE (%) against the dependent variable which is the stock
price separately in three different graphs. From the three graphs, we were able to conclude the
linearity.
Please refer to Appendices B and C for the linearity graphs.
2nd Assumption: Normal Distribution.
Figure 4: Histogram of the Frequency versus the Regression Standardized Residual.
The figure above shows a histogram of frequency vs. regression-standardized residuals. The
graph demonstrates that the residuals are normally distributed.
3rd Assumption: Independence of errors.
Durbin-Watson: We have found that Durbin-Watson = 1.953 close to 2
Which means that we do not have a positive autocorrelation.
4th Assumption: Equality of variances.
Using SPSS, the graphs confirm that there is no pattern of residual errors. (See Appendix C).

3. Methodology and Findings:
Methodology:
To reach the objective of our project, we have conducted a research in order to know what
are the factors influencing the stock price of the Moroccan firms. We have conducted a multiple
regression analyses by using the statistical tools we have learned throughout this semester. The
way our team have preceded is as followed:
Looking for the factors influencing the stock price of companies in other
countries.
Select only the factors that are significant to our study and applicable to the
Moroccan context.
Dependent variable:
Y: Stock price is the price of a single share of a number
of saleable stocks of a company, derivative or other
financial asset.
Independent variables:
X1: Book value is a measure of all of a company's
assets: stocks, bonds, inventory, manufacturing
equipment, real estate, etc.
X2: Return on equity (%) effectively measures how
much profit a company can generate on the equity
capital investors have deployed in the business, and can
be used over time to evaluate changes in a company’s
financial situation. In other words, Return on Equity
indicates the amount of earnings generated by each
dollar of equity.
X3: Earnings per share is the amount earned on behaves
of each outstanding common stock not the distributed
amount to shareholders. This is perhaps the most
important factor for deciding the health of any company
and they influence the buying tendency in the market. It
can measure the profitability of the company.
Plot the data and run the regression through SPSS software and Excel also.
Make sure that we met all four assumptions.
Analyze and interpret all the output results.
