Summary (1)
• First sophisticated, large scale analysis of
Islamic equity funds‘ financial performance and
especially investment style
– 262 funds from 20 countries for up to 20 years
• Development of a “three level Carhart model“ to
simultaneously control for national, regional or
global equity market and investment style
exposure
– Modified versions to
• allow for time varying factor exposure
• Investigate performance during losing markets and crises
2
Summary (2)
• Findings:
– Western Islamic equity funds significantly underperform
– Islamic equity funds seem to have a small cap preference
given their restrictions on corporate revenues from haram
activities
– Islamic funds from the predominantly Muslim GCC
countries and Malaysia neither significantly underperform
nor have a clear small cap preference
• This is theoretically intuitive given the more Shari‘ah
compliant economies.
– Some evidence that Islamic funds exhibit a hedging
function, as their universe is limited to low debt/equity
ratio firms

Background
• Islamic Investment is a multibillion dollar industry with
hundreds of funds and indices (Dow Jones, FTSE, MSCI,
S&P)
• Islamic Funds are defined by their Shari‘ah compliance
• Shari‘ah law prohibits
– Riba al Nasiah (receipt of interest on capital)
• Prevents from bonds, warrants etc.
– Maysir and Gharar (Gambling and uncertainty)
• Prevents from leverage, short selling, derivatives
– Haram (forbidden) products and services
• Prevents from i.e. pork, (non-medical) alcohol or weapons
• Contemporary Shari’ah scholars tend to allow investment in
stocks with tolerable proportions of revenues from prohibited
activities under the condition of Haram purifcation (donation of
impure distributions to charity)

Theoretical perspective on Islamic
funds‘ performance and style
• Shari‘ah law
– prevents a pure profit focus but might be good long term risk
management
– restricts market risk timing abilities, which, on average, do not
generate value (e.g. Bollen & Busse, 2001)
• Islamic funds are less resticted in economies more affected
by Shari‘ah law due to a smaller degree of intolerable stocks
• Shari‘ah compliance of products and services is likely
financially more beneficial in economies with a higher degree
of Muslim consumers
• Islamic funds‘ investment style probably
– exhibits under-proportional betas,
– small cap exposures, as large, diversified companies more likely
have intolerable proportions of revenues from prohibited activites

Previous research on Islamic funds‘
financial performance and investment style
• “Next to nothing“
• On financial performance the benchmarks are
– CAPM for 59 funds for 5 years (Kraeussl & Hayat, 2008)
– CAPM for 14 Malaysian funds for 10 years (Abdullah et al.,
2007)
• On investment style, the reliable benchmark is
– Investigation of size and value/growth exposure of 6 US
funds over 5.7 years
• Hence: We claim to pursue the first sophisticated, large
scale analysis of Islamic equity funds‘ financial
performance and investment style

Research Questions
(1) Does the financial performance of Islamic
equity mutual funds significantly differ from the
respective equity market benchmark?
(2) Which investment styles are preferred by
Islamic equity mutual funds?
(3) Is Islamic mutual funds’ performance
differential to their respective market
benchmarks significantly better in losing
markets and especially in (financial) crises?
(4) Do national differences exist in the answers to
questions (1)-(3)?

Data
• “Data shortage in Islamic equity fund studies“
• Survivorship bias adjusted sample of 262 Islamic equity funds
from Eurekahedge starting with the launch for the first fund in
09/1990 and ending in 04/2009
• We construct equal weighted national portfolios
• Descriptive Stats (in Table 1) show
– Asia-Pacific, GCC and Europe to be leading regions
– Malaysia, Saudi-Arabia and UK (inclusive overseas Islands) to
be leading countries
– Attrition rates in line with conventional funds
– Very diverse geographic foci require special model
• Carhart (1997) model variables from Style Research Limited
based on Worldscope database
• Risk free asset returns from Datastream

National financial performance and
investment style
• Carhart (1997) model
rp ,t   p   nat, p rnatm,t   nat, p SMBnat,t   nat, p HML nat,t  nat, p MOM nat,t   p ,t
• Our results (in Table 2) show:
– Significant underperformance in 75% of cases
– Half of the national portfolios to have a significant
preference for small cap stocks
• Effect much more pronounced for Western countries
– A tendency to prefer growth over value stocks at
national level
– No tendency towards momentum or contrarian
stocks

International financial performance
and investment style
• To control for diverse geographic foci, we develop a three level
Carhart (1997) model using Elton et al.‘s (1993) orthogonalization
approach:
rp ,t   p   nat, p rnatm,t   reg , p rregm,t   glo, p rglom,t   nat, p SMBnat,t   reg , p SMBreg ,t
  glo, p SMBglo,t   nat, p HMLnat,t   reg , p HMLreg ,t   nat, p HML glo,t  nat, p MOM nat,t
 nat, p MOM reg ,t  nat, p MOM glo,t   p ,t
• Our results (in Table 3) show:
– In nearly all cases a substantially higher Adj. R-squared
– Interesting picture of national, regional and global exposure
– Model eliminates nearly 50% of the significant underperformances
• Only 8, mostly Western, national portfolios significantly underperform
– All GCC portfolios and Malaysia perform comparable or better
• Supports theoretical perspective on relevance of „Muslim economies“
– Small cap preference remains in contrast to growth stock preferences

• Our results (in Table 4) show:
– Some evidence of a hedging function of Islamic funds
in losing markets
– No evidence of a specific, additional crisis hedging
function of Islamic funds

Conclusion (1)
• Islamic equity funds, on average, trail their benchmarks
– Possible (complementing) explanations:
• Shari‘ah law compliance
• Active investment strategy
 To be differentiated, once sufficient data becomes available
• Islamic equity funds have small cap preference
– Theoretically intuitive given limited tolerance to revenues from
prohibited activities
• The density of Muslim consumers in an economy
appears positively related to Islamic funds‘ financial
performance and large cap exposure
– Explanations: A higher Shari‘ah compliance in an economy
• mitigates the restrictions on Islamic funds
• increases the probability that Shari‘ah compliance is financially
beneficial for corporations
12
Conclusion (2)
• Islamic funds appear to have a bit of a hedging
function in losing markets but are no additional
hedge in crises
– The hedging function theoretically intuitive, as Islamic
funds are restricted to invest in companies with a low
debt/equity ratio
• Our three level Carhart model and its extensions
appear very useful in the analysis of
geographically diverse investment strategies like
Islamic funds
– It might hence be valuable for other analyses of asset
pricing or investment performance evaluation

Robustness test
• We extend our three level Carhart model to allow for
time varying factor exposure in line with Ferson and
Schadt (1996) and Cortez et al. (2009):

• Our results (in Table 5) show:
– Our results of Table 3 are robust to time variations in factor
exposure, as only two alpha coefficients change their
significance level in opposite directions in conditional
model
– Most Islamic fund managers do not seem to vary their
exposure over time,
– The few, which do, fail to generate alpha with it
