The research examines the Capital Asset Pricing Model
(CAPM) in Damascus Stock Exchange (DSE), by using the
monthly excess returns of (8) companies listed in (DSE), for the
period of (2010-2013), and the monthly excess return of (DSE)
index (DWX)
for the same period.
The researcher concluded that there is a significant relation
between the volatility of the market excess return and the volatility of the excess returns of stocks of the examined companies, But the researcher also concluded that (CAPM) is not valid in (DSE), because of the failure in the statistical test. That the constant of the regression equation is not equal to zero and the slope of the security market line is not equal to the average excess return of the stocks of examined companies.
The researcher recommended that this study should be retested
when there are a suitable number of listed companies in order to
form portfolios that can diversify away the effect of the unsystematic risk of each company, and to retest the CAPM after
the crises, because the average excess returns for all of the
examined companies were negative. Finally, the researcher
recommended trying other models of asset pricing such as
Arbitrage Pricing Theory (APT), and (Fama) Multifactor Model.
The objective of this research is to test the stability of systematic risk coefficients of stocks listed on the Damascus Securities Exchange through the period (4/1/2010 – 28/10/2013), and therefore the ability to use the values of these coefficients
to calculate the required rate of return on investment in the individual stocks and portfolios.
The data related to the closed prices of stocks and market index were collected from the website of DSE, which is used to estimate the values of systematic risk (Beta). Then the researcher has tested the stability of the coefficients throughout the entire period and the three sub-periods each one consists of five yearly quarters by using the time as a variable in the regression model, and by testing the significance of the coefficient of time variable.
The results of the research show that greater than 80% of these coefficients were insignificant, that is, the higher percentage of stocks have a stable Beta, and can be used to calculate the required rate of return on investment, therefore suitable investment decisions may be made upon these results.
This study aimed to examine the weak form efficiency of the
Damascus Securities Exchange (DSE). The study used the monthly
returns, adjusted for thin trading, of firms listed in the Damascus
Securities Exchange from 2009 until 2014 and applied var
ious tests
to examine the random walk behavior in returns: the unit root test,
the autocorrelation test, the runs test and the GARCH model. To
take the impact of the Syrian crisis into account when judging the
efficiency of the market, the study period was divided into three
periods, the pre-crisis period, the crisis period and the whole period.
The results revealed inability to reject the weak form efficient
market hypothesis for more than half of the studied firms. Also it
showed that the Syrian crisis, in general, has negatively affected the
efficiency of most of the studied firms.
The individuals’ Participation in the Securities Exchange plays an important role in
the development of the financial market. Without the active and continuous participation,
the financial market lacks the financial products and its liquidity, and
also the increased
participation leads to the creation of effective trading dynamics of buying and selling.
This paper examines the impact of financial literacy on the individuals’ Participation
in Damascus Securities Exchange. To achieve the objective of the study, data is collected
based on a questionnaire specially designed for this purpose. And the questionnaire has
been distributed to a sample of (384) individuals from the merchants and industrialists who
are registered in the Damascus Chamber of Commerce and Damascus Chamber of
Industry. The study to analysis data depends on using a software of Statistical Package for
the Social Sciences known as SPSS. It has been used some statistical methods like
repetition and percentages in addition to Chi-Square Test to examine hypotheses
concerning the relationship between demographic variables and financial literacy, and a
model logistic regression to study the impact of financial literacy on the individuals’s
participation in the Damascus Securities Exchange
The research finds that the financial literacy of the members of the respondents is
very far from the desired level to participation in the Damascus Securities Exchange where
only (22%) of respondents have a good level of financial literacy. In addition to that, the
research highlights the presence of a statistically significant effect of financial literacy to
participate in the securities exchange; the increasing financial literacy index from a low
level to a better one leads to increase the likelihood of participation by (24%). The research
also concludes two things that there is a relationship between each of the variables of
gender, income and financial literacy, and on the other hand there is no relationship
between the educational qualification and the financial literacy.
The study aimed to evaluate the efficiency of the performance of the
brokerage firms and financial services operating in the Damascus
Securities Exchange from the point of view of investors in the market,
study sample included 150 investors, and u
sed the questionnaire to
investigate investors' opinions about brokerage firms operating in the
market and the role they play during the period from December until the
end April of 2015, where the answers were analyzed using spss program.
