throughout 2022, except for Q1 2022 due to the high rainy season, ITMG's coal
production growth is quite solid, and investors' high expectations that ITMG will
distribute dividends at a ratio of 70% of 2022 net profit like the previous year's dividend
distribution ratio.
Table 4 shows the results of linear regression which can be explained as follows:
1. Based on R
, R2, and
Adjusted R2, Small Low portfolios are the only portfolios that have
values close to 1 (0.899, 0.808, and 0.606), which means that the independent variable
has a high correlation (89.9%0, and is able to explain 80.8%/60.6% variance of the
dependent variable. Meanwhile, the Small Medium portfolio has the lowest value
among the six portfolios with values of 0.118, 0.014, and -0.197. The meaning of this
value is, the independent variable has a low correlation of 11.8%, and is only able to
explain or not able to explain at all when viewed from the negative Adjusted R2
value to the dependent variable. If the linear regression of the portfolio is based on
the year, it can be seen that the R
, R 2, and Adjusted R2 values of the portfolio in 2020, and 2022 have values close to 1
(R, and R 2
), and above 0.5 (
Adjusted R2). Different results were obtained in the 2021
portfolio which had the lowest value compared to the other two portfolios.
However, when compared to the linear regression results of each 6 portfolios, the
values of R, and R 2 are only inferior to the values of R, and R2 Small Low. However,
for the Adjusted R2 value, the 2021 portfolio is only higher than the Big High, Small
High, and Small Medium portfolios.
2. Based on the F value, the High-Low portfolio is the only portfolio where hypothesis
H4 is accepted. In this portfolio, a set of independent variables has a strong influence
on the formation of dependent variables. In other portfolios, hypothesis H4 is
rejected. Based on the results of linear regression it was found that a set of
independent variables has a weak influence on the formation of expected return.
However, when the six portfolios are combined and separated only by year (2020,
2021, and 2022), the results show that a set of independent variables has a weak
influence on the formation of expected returns.
3. Based on the t value, the majority of portfolios (Big High, Big Low, and Small High)
the formation of expected return is influenced by the JCI variable, which means H5
is accepted. SMB has only the greatest influence on the formation of expected return
2 portfolios (Big Medium, and Small Medium), meaning H6 is received. The
independent variable HML has only the greatest influence on the formation of the
portfolio's expected return of 1% (Big Low), meaning H7 is received. However,
when the six portfolios are combined and separated only by year (2020, 2021, and
2022), it is found that HML has a strong influence on the formation of expected
returns for all portfolios in 2020, and 2021, which means H7 is received. However,
in 2022, JCI is an independent variable that has a strong influence on the formation
of expected returns for the entire portfolio, which means H5 is received.
