Abstract: The purpose of this study was to examine the ability of the Fama-French Five-Factor Model in providing
explanatory power to banking stock excess returns on the Indonesia Stock Exchange. In examining the
validity of the model, this study was conducted to determine how the influence of five factors consists of
market risk, book-to-market ratio, market capitalization, profitability and investment in excess return of
banking stock portfolio. The test in this study uses time series data by analyzing multiple linear regression
for each portfolio that is formed based on the Fama-French five-factor model. The data used in this analysis
are the daily average return of the bank's stock portfolio every month, the average daily market return every
month, and the interest rate of Bank Indonesia Certificate as the rate for risk-free investments every month
in the period from January 2012 to December 2017. The results show that the use of variable operating
profit and investment gives anomalous results to banks that have a small market capitalization. But the use
of variable operating profit and investment can provide a strong explanation of the optimism and pessimism
of investors, especially in banks with a large market capitalization
1 INTRODUCTION
The valuation model that is well-known and widely
applied in the world of capital markets is the Capital
Asset Pricing Model (CAPM). This model is very
popular since 1964 and researched separately by
William Sharpe (1964), John Lintner (1965),
and Mossin (1966). The CAPM model is portfolio
theory development proposed by Markowitz (1952)
by introducing a new term, namely systematic risk,
and non-systematic risk. The risk measure used
in CAPM is beta. Beta is used as a measure of the
volatility of a security or portfolio return to market
returns. In other words, beta estimation is done by
collecting historical values of returns from securities
and returns from the market within a certain period
(Hartono, 2010). The concept of the relationship
of β (systematic risk) with the return is explained by
the security market line (SML). The relationship of
expected return and risk lies in the SML line, with
the main components of the CAPM including the
risk-free rate of return, and the risk premium for
securities. The simple calculation process and the
ease of obtaining the required data is a special added
value for the CAPM. However, over time
the CAPM began to show its weaknesses. According
to Tandelilin (2003) the possibility of errors in the
application of CAPM originating from beta
changes according to the length of the observation
period in the study, the market index used does not
represent the entire marketable assets in the
economy and the company's fundamental
fluctuations such as earnings, cash flows, and
leverage affect the beta value . Similarly, by looking
at the real conditions of the market, the validity
of CAPM is often questioned. In addition to the
above, some other researchers also doubt
the CAPM model which only uses beta as the only
indicator of return assessment. They assume that
there are other variables besides beta that can affect
stock returns.
Fama and French (1992) have developed a stock
pricing model by combining the Capital Asset
Pricing Model (CAPM) and Arbitrage Pricing
Theory (APT). This model is known as the Fama-
French three-factor model where the variables
consist of market risk used in CAPM, size and book-
to-market ratio. Size is seen through the stock
market capitalization value. The use of market
capitalization as a factor is due to the difference
between the risks in the stock and the small market
capitalization which tends to have a higher risk

compared to stocks that have big capitalization so
that stocks with small market capitalization have
higher expected profit levels compared to stocks
with big capitalization stocks. The use of book-to-
market ratios as a factor due to the high book-to-
market reflects investors who are pessimistic about
the company's future. Conversely, if investors are
optimistic about the future of the company, then the
value of book-to-market will be low. According to
Fama and French (1992) that these variables can
explain the average stock returns in a cross section
well. Likewise with other studies that have been
carried out such as Liew and Vassalou (2000),
Griffin and Lemmon (2002), Lettau and Ludvigson
(2001, 2006), Tandelilin (2003), and Bello (2008).
They have the same conclusions as for the results of
the Fama and French research. Therefore, the Fama-
French three-factor model has been used as a
reference in the literature on asset pricing.
Fama and French (2015) added two factors in the
asset pricing model to become five factors. Two
factors added in the model are profitability and
investment factors. The use of these two factors is
based on the model used in Novy-Marx (2013)
which gives the conclusion that higher returns tend
to occur in companies that have high profitability
compared to companies that have low profitability
and the results of Aharoni et al. (2013) who found
that there was a statistically significant relationship
between proxy investment and the average rate of
return. Fama and French (2015) use operating profit
as a proxy for profitability and change in total assets
as a proxy investment. In their research, Fama and
French (2015) found that the five-factor model was
better than the three-factor model in explaining stock
excess returns in the United States. Likewise with
other studies such as Chiah, et al. (2015) which
compares the performance of Fama-French three-
factor model and Fama-French five-factor model in
the Australian stock market in the period January
1982 to December 2013 where the research found
that the addition of profitability and investment
provides explanatory power on market risk,
profitability and investment factor and able to
explain anomaly better than other asset pricing
models
However, despite its success in some cases, there
are also other cases that deviate from the discovery
of Fama-French. Cakici (2015) using company-level
data from July 1992 to December 2014, which forms
size-to-market, size-gross profitability (GP) and
size-investment. Cakici (2015) found that the HML
factor (High Minus Low) or the difference in book-
market stock portfolio returns is high with the low
book to market share portfolio strongly influential in
all regions of the world, except North America.
Profitability factor is only significant in Europe and
the global market, but not for North America, Japan,
and the Asia Pacific. Significant investment factors
on Global, European and North American (slightly
significant), but not significant in Japan and the Asia
Pacific. These studies assume that the five-factor
model of Fama-French is less able to adapt to every
market situation in different regions and countries in
the world.
Martins and Jr (2015) re-examined the
performance of Fama-French three-factor and Fama-
French five-factor by using data obtained from the
Brazilian stock market in the period 2000-2012. The
results of this study indicate that market risk, size,
and Market-to-book ratios have the effect of most
variations in average returns. While for the new
variables which include profitability and investment
have explanatory power that is still relatively weak,
but still able to provide a better explanation than the
Fama-French three-factor model.
Sutrisno and Ekaputra (2016) from Indonesia
conducted research on Fama French Five Factors
using secondary data obtained from Thomson
Reuters Datastream during the period July 2000 to
June 2015. The results concluded that the Fama-
French five-factor model has the better capability in
explaining the excess return of the stock portfolio in
Indonesia compared to the Fama-French three-factor
model, although profitability and investment factors
have a weak effect on excess return. A significant
intercept of empirical tests of Fama-French asset
pricing models in Indonesia in every set of portfolios
25 indicates that the Fama-French model is invalid
in Indonesia. With the addition of profitability and
investment factors, the book-to-market factor is
redundant in explaining the excess return of stock
portfolios in Indonesia. This can be seen when the
book-to-market factor is re-enacted with four other
factors, the value of the intercept is near zero and
insignificant. In conclusion, the findings in
Indonesia support the findings of Fama and French
(2015) in the US.
Elliot et al., (2016) presents a comprehensive ex-
post analysis of Australian stock returns over the
period 1975 to 2013. Using concentrated datasets
with stocks showing high investment but low profits,
the researcher suggests that additional factors such
as profitability and investment are inconsistent and
insignificant in explaining stock returns. While the
market-to-book factor has a redundant power to the
stock return. Huynh (2017) compared the ability of
Fama-French three-factor to Fama-French five-

factor in explaining the profit opportunities obtained
from the selection of several anomalies in the rate of
return of Australian equity. The results obtained are
the Fama-French five-factor model capable of
explaining 16 anomalies from the 19 selected
anomalies. So that the Fama-French five-factor
model is considered better than the Fama-French
three-factor. Where the market-to-book factor is
very significant in explaining stock returns, the
results of factor profitability and investment are very
large and very significant, while the size factor is
insignificant.
Estimating risk and stock returns are important
for investors, so estimating with the Fama-French
model is one way to predict and identify the
movement of stock returns in the company. The
effect of market risk, size, market-to-book,
profitability, and investment on excess return has
been widely studied in various countries' capital
markets. However, in the Indonesian capital market
itself, especially in the Indonesia Stock Exchange
(IDX), research with the Fama-French model is still
very limited. This research uses a sample of the
banking stock population listed on the Indonesia
Stock Exchange. The bank is a company that has
more complex risks than other companies. The
Fama-French five-factor model in which investment
factors are included in the model is very suitable in
this study because the Bank has a risk in investing in
productive assets that are heavily influenced by
market risk so that the decision in determining the
number of assets is influenced by market risk. On
the other hand, profitability is also influenced by the
quality of assets that have asset quality due to
market risk conditions at that time, because asset
quality is influenced by market risk, indirectly
profitability is also influenced by market risk. The
regulation of the Bank's minimum capital limitation
in financing assets is one of the factors that influence
the expectation of higher excess returns so that the
market capitalization has a link between profitability
and bank investment, this variable also has an
impact on the volume of stock sale transactions that
occur where the large volume of stock sales will
have an impact on the high or low book-to-market
ratio so that the use of the Fama-French five-factor
model is in accordance with the research using a
sample of banks whose shares are traded on the
Indonesia Stock Exchange.
2 METHODS
Fama and French (1992) suggested that the CAPM
model that uses only single factor models cannot be
market beta as a whole so that other factors are
needed to complement market risk factors. The
factors used to complete market risk are market
capitalization (size) and market-to-book. Based on
research conducted by Fama-French (1992) in
looking at the effect of size on stock excess returns,
each company is first divided into two groups:
companies that have big market capitalization and
small market capitalization where grouping is based
on the median that has calculated the total market
capitalization of the company. Grouping is divided
into companies with a total market capitalization that
are above the median into companies that have a big
size (B), while companies with market capitalization
that are below the median become companies that
have small size (S). The same thing is done in
grouping based on the market-to-book ratio.
Furthermore, it is calculated the difference between
stock returns with a big market capitalization (B)
and small capitalization (S), the same thing is also
done between stock returns with high (H) and low
(L) book-to-market. In the formation of portfolios in
independent variables, a grouping consists of 4
portfolios, namely companies with big market
capitalization (B) and high book-to-market (H),
companies with small market capitalization (S) and
low book-to-market ( L) and so on to become a
portfolio of B / H, B / L, S / H, S / L. Each portfolio
is calculated as excess return and regressed with the
following equation:

This study uses the Fama-French five-factor
model by entering the profitability and investment
variables in which the grouping of banks that have
robust (R) and weak (W) profitability and banks that
have conservative (C) and aggressive (A)
investments are the same as the groupings used in
size and book-to-market. Furthermore, the excess
return difference between banks that have robust
operating profitability and weak is sought (robust
minus weak), the same thing is also done to find

The population in this study were all banks listed on
the Indonesia Stock Exchange (IDX) in the period
2012 to 2017. The samples in this study were
selected from the entire population using purposive
sampling method with criteria for banks listed on the
Indonesia Stock Exchange from January 2012 to

Before testing the hypothesis in this study,
we formed a stock portfolio of 28 Bank samples
using models such as Fama and French (2015) with
sorts of 2 x 2 x 2 x 2 on size, book-to-market,
operating profit and investment consisting of
portfolios : 1) S/H//R/C; 2) S/H/R/A; 3) S/H/W/C;
4) S/H/W/A; 5) S/L/R/C; 6) S/L/R/A; 7) S/L/W/C;
8) S/L/W/A; 9) B/H/R/C; 10) B/H/R/A; 11) B/H
/W/C; 12) B/H/W/A; 13) B/L/R/C; 14) B/L/R/A; 15)
B/L/W/C; 16) B/L/W/A. Where S is a bank that has
small market capitalization, B is a bank that has big
market capitalization, H is a bank that has high book
to market, L is a bank that has low book to market,
R is a bank that has robust operating profitability
and a bank that has weak operating profitability, C is
a bank that has conservative investment and A is a
bank that has aggressive investment. By using the
Fama and Fench (2015) model, the determination of
the dependent and independent variables in this
research are:
1) Dependent variables: The dependent
variable used in this study is the excess
return of each bank's stock portfolio that
has been formed as the pattern specified
above. After forming a portfolio, the excess
return for each portfolio is calculated
monthly with the formula: Rit - Rft. Where
Rit is the average daily portfolio return
every month and Rft is the Bank Indonesia
rate (BI Rate) every month.
2) independent variable: the independent
variable used in this study consists of:
a) SMB (Small Minus Big) is the
difference in average returns on eight

279
stock portfolios with small market
capitalization and average return on
eight stock portfolios with big market
capitalization. Grouping portfolios in
banks by categorizing shares with 50
percent market capitalization below,
and 50 percent market capitalization.
The market capitalization used to
classify shares in forming a portfolio
each year is market capitalization at the
end of December t-1 adjusted for
changes in the number of shares
outstanding at the end of December.
The SMB equation above is as follows:
SMB = (S/H/R/C + S/H/R/A +
S/H/W/C + S/H/W/A + S/L/R/C +
S/L/R/A + S/L/W/C + S/L/W/A)/8 –
(B/H/R/C + B/H/R/A + B/H/W/C +
B/H/W/A + B/L/R/C + B/L/R/A +
B/L/W/C + B/L/W/A)]/ 8.
b) HML (High Minus Low) is the
difference between the average return
of eight stock portfolios with a high
book to market ratio and the average
return of eight stock portfolios with a
low book to market ratio based on the
proportion of 50 percent stock portfolio
formation for the lowest group (Low),
and 50 percent for the highest group
(High). The book equity used to
classify shares in forming a portfolio
each year is book equity at the end of
December t-1 while the market
capitalization class is the same as the
above classification of SMB. HML
equation as follows: HML =(S/H/R/C
+ S/H/R/A + S/H/W/C + S/H/W/A +
B/H/R/C + B/H/R/A + B/H/W/C +
B/H/W/A)/8 – (S/L/R/C + S/L/R/A +
S/L/W/C + S/L/W/A + B/L/R/C +
B/L/R/A + B/L/W/C +B/L/W/A)/ 8
c) RMW (Robust Minus Weak) is the
difference in the average return on
eight stock portfolios that have a high
operating profitability value with an
average return on eight portfolios that
have a low operating profitability value
by classifying operating profitability
based on the proportion of 50 percent
for the highest group ( robust) and 50
percent for the lowest group (weak).
Profitability used to classify shares in
forming a portfolio each year is
profitability at the end of December t-
1. RMW equation as follows: RMW =
(S/H/R/C + S/H/R/A + S/L/R/C +
S/L/R/A + B/H/R/C + B/H/R/A +
B/L/R/C + B/L/R/A)/8 – (S/H/W/C +
S/H/W/A + S/L/W/C + S/L/W/A +
B/H/W/C + B/H/W/A + B/L/W/C +
B/L/W/A) / 8
d) CMA (Conservative Minus
Aggressive) is the difference between
the average return of eight stock
portfolios that have high investment
value with the average stock portfolio
return which has low investment value
by classifying investments based on the
proportion of 50 percent for the lowest
group (Aggressive), and 50 percent for
the highest group (Conservative). The
investment used to classify shares in
forming a portfolio every year is an
investment at the end of December t-1.
CMA equation as follows: CMA =
[(S/H/R/C + S/H/W/C + S/L/R/C +
S/L/W/C + B/H/R/C + B/H/W/C +
B/L/R/C + B/L/W/C) – (S/H/R/A +
S/H/W/A + S/L/R/A + S/L/W/A +
B/H/R/A + B/H/W/A + B/L/R/A +
B/L/W/A)] / 8
The data analysis technique used is multiple
linear regression with time series data with a total of
72 months by regressing each independent variable
with the excess return of each portfolio with the
following equation (2) above.
3 RESULTS AND DISCUSSION
In providing a better explanation of the four factors
that affect the excess return of the banking stock
portfolio, this study first calculates the daily average
portfolio return every month in the period January
2012 to December 2017 based on 4 factors
consisting of size, book-to-market, profitability, and
investment so that it can be seen that there is an
interaction between one independent variable and
another in generating the average return. The results
of this calculation form the pattern presented in
Table 2:
IRCEB 2018 - 2nd INTERNATIONAL RESEARCH CONFERENCE ON ECONOMICS AND BUSINESS 2018
280
Table 2: Average Monthly Return
The average bank stock return with small market
capitalization shows that the average stock return
that has robust profitability give higher return if
book-to-market gets higher. But if the Bank has low
profitability it does not show the difference in the
average significant return between low or high book-
to-market conditions. These results indicate that
there are pessimistic investors in banks with a small
market capitalization that provides weak
profitability. If we look at the relationship between
book-to-market and investment, it shows the
negative relationship in generating high average
returns, where high book-to-market with aggressive
investment gives a high average return and if low
book-to-market with conservative investment also
gives a high average return. The results show that
investors are optimistic that banks have low market
prices to make aggressive investments and high
market prices to make conservative investments. If
we look at the relationship between profitability and
investment in generating average returns, it indicates
that banks that have robust operating profitability
and aggressive investments provide average higher
return while robust operating profitability with
conservative investment provides a lower average
return. When the Bank is in a condition of having
weak operating profitability, there is no difference in
the average significant return in the conservative and
aggressive investment conditions. These results
indicate investors are optimistic about banks that
have robust profitability to invest aggressively.
The average stock return of banks that have big
market capitalization shows high average return if
the Bank has low book-to-market with robust
profitability but provides an average low return if
weak profitability. In the low book-to-market
condition there is no significant difference in the
average return between banks which provide robust
and weak profitability. These results indicate that
investors are optimistic about banks with big market
capitalization to have high book-to-market and
robust operating profitability. Likewise, with
investments where banks that have low book-to-
market will have an average high return if the
investment is aggressive but will provide an average
low return if the investment is conservative. These
results indicate that investors are optimistic that
banks have low book-to-market to invest
aggressively. In looking at the average return
generated in terms of the relationship between
operating profitability and investment shows a
significant difference, so this result shows that
relation between operating profitability and
investment provide more explanatory power to the
average return on companies that have big market
capitalization. The results from Table 2 show that
operating profitability and investment provide a
strong explanation for the average bank stock return
which has big and small market capitalization.
Before conducting multiple linear regression
analysis on time series data, a classic assumption test
consisting of multicollinearity test and
autocorrelation test is needed as presented in Table 3
Table 3: Classic Assumption Test
Multicollinearity testing results in a perfect
correlation between SMB and RMW variables so
that the multicollinearity test between SMB and
RMW variables is done separately by doing two
tests, namely multicollinearity testing between
variables using the SMB variable and take out the
RMW variable, then doing multicollinearity testing
again with enter the RMW variable and take out
SMB variable so that there is no multicollinearity.
The autocorrelation test results using the Langrage
Multiplier test (LM-Test) where the results show no
Prob. Chi-Square (2) is below 5 percent so it can be
said that autocorrelation does not occur for each
portfolio.

In this study, each portfolio was regressed twice
by using the SMB and RMW factors alternately.
This is done because of the problem of
multicollinearity between SMB and RMW. The
influence of five independent variables (market risk,
size, a book to market ratio, operating profitability,
and investment) on the dependent variable namely
excess return for each portfolio from January 2012
to December 2017 was tested using time series data

Market risk has a positive effect on the excess return
of all portfolios where this result shows that the
market risk variable is a systematic risk that has a
very strong impact on the banking industry in
Indonesia. Market capitalization (SMB) has positive
and significant effect on the S/H/W/C portfolio
excess return but has negative and insignificant
effect on the S/L/W/C portfolio excess return, then
market capitalization (SMB) has a negative and
significant effect on B/H/R/C and B/L/R/A portfolio
excess returns. These results indicate that market
capitalization cannot show an explanation of the
Bank's excess return in Indonesia by using a 2 x 2 x
2 x 2 pattern where the research was previously
Fama and French (2015), Martins and Jr (2015), and
Huynh (2017) Using portfolio formation with a
pattern of 2 x 2 and 2 x 3 can show a significant
explanation of the effect of market capitalization
(SMB) on excess return. The use of patterns in this
study shows anomalies where the effect of market
capitalization is positive on S/H/W/C portfolio
excess return and negative on the B/H/R/C and
B/L/R/A portfolio excess return which are not
suitable as presented in Table 2.
The anomaly results also occur in the analysis
of book-to-market influence on excess returns which
shows a positive and significant effect of book-to-
market (HML) on S/H/W/C portfolio excess return
and negative and significant effect on portfolio
excess return S/L/W/C where Table 2 shows that
S/L/W/C portfolio should provide a higher average
return compared to the S/H/W/C portfolio. The
results of this anomaly are in accordance with the
conclusions of Fama and French (2015) that the
addition of variable operating profit and investment
provides anomalies caused by the existence of small
companies that invest aggressively with low
operating profit so that high investments made in the
company become a problem in research.
But the pattern of 2 x 2 x 2 x 2 in this study can
explain that the effect of operating profit and
investment on the excess return of the Bank's
portfolio in Indonesia. These results are shown in
Table 4 where operating profit has a positive and
significant effect on excess return portfolio B/H/R/C
and B/L/R/A. These results indicate that the pattern
of 2 x 2 x 2 x 2 can show that operating profit
explains the relationship between book-to-market
and investment where banks that have high book-to-
market and conservative investments give the same
results as banks that have a low book-to-market and
aggressive investment in large banks if the operating
profit condition is robust. But the results that occur
in small banks cannot provide an explanation for the
book-to-market relationship with investment. These
results reinforce the same conclusion from Fama and
French (2015) which has been stated that small
companies with small profits carry out high
investment actions so as not to influence investors'
optimism.
The influence of investment presented in Table
4 can also explain the reciprocal relationship
between market capitalization, book-to-market and
operating profit where investment has a positive and
significant effect on the excess return on the
S/L/W/C and B/H/R/C portfolios. These results
indicate that investors prefer small banks that have
low book-to-market but produce weak operating
profit and large banks that have high book-to-market
but generate robust operating profit to invest
conservatively. These results can provide an
explanation that the pattern of 2 x 2 x 2 x 2 used in
this study can better explain that investment can
provide a pessimistic and optimistic relationship
between investors through conservative investments
by banks compared to previous studies that applied 2
x 2 and 2 x 3 patterns.
4 CONCLUSION
This study is to test the five-factor model developed
by Fama-French (2015) on banks listed on the
Indonesia Stock Exchange. This research was
conducted because there are still not many studies
that use the Fama-French five-factor model to test its

validity in Indonesia. The use of banks as samples in
this study is because banks have assets that are
riskier than other companies and the management of
banks in generating profits is a factor that is very
much considered by investors so that it is more
suitable in testing operating profit and investment
factors used in Fama-French five-factor model.
The pattern used for the formation of portfolios
using 2 x 2 x 2 x 2 is rarely done by previous
research with the intention of operating profit factors
and investment can provide explanatory power that
can influence other factors on excess return. The
application of this pattern provides anomalies in
testing market capitalization and book-to-market
factors. But this pattern can explain that investors
are pessimistic and optimistic about large banks in
investing in terms of the operating profit they have.
The results show investors like a high investment if
they generate high profits and low investment if
profits are low. But this relationship does not occur
in banks that have small assets due to the high
investment made by small banks even though the
resulting profits are low so there is an anomaly in
the results of this study
The results obtained from testing the portfolio
of small banks provide anomalies in testing the
factors of market capitalization, book-to-market, and
operating profit, giving a finding that investors
prefer small banks to invest low in their assets. This
result is reinforced by the results of the test of the
effect of the investment on excess returns where
investors are optimistic about small banks that make
conservative investments if their book-to-market has
a low.
