ABSTRAK
Penelitian ini bertujuan untuk mengetahui dan menganalisis pengaruh
variabel ekonomi makro dan ekonomi mikro terhadap volatilitas Indeks Saham
LQ45. Variabel ekonomi makro dalam penelitian ini adalah nilai tukar, inflasi, BI
Rate, Produk Domestik Bruto (PDB), dan volume perdagangan, sedangkan
variabel ekonomi mikro adalah Earning Per Share (EPS), Price to Book Value
(PBV), Debt to Equity Ratio (DER), dan Return On Equity (ROE). Data yang
digunakan adalah data time-series dengan periode penelitian Januari 2009 sampai
September 2014. Analisis yang digunakan dalam penelitian ini adalah metode
analisis deskriptif kuantitatif dengan menggunakan tiga model, pertama model
variabel ekonomi makro dan ekonomi mikro secara bersama-sama terhadap
volatilitas Indeks Saham LQ45, model kedua yaitu variabel ekonomi makro
terhadap volatilitas Indeks Saham LQ45, dan model yang ketiga yaitu variabel
ekonomi mikro terhadap volatilitas Indeks Saham LQ45.
Untuk melihat pengaruh antara satu variabel dependen dengan variabel
independen dilakukan dengan menggunakan metode Error Correction Model
(ECM), sedangkan untuk mengukur volatilitas Indeks Saham LQ45 digunakan
analisis ARCH-GARCH. Hasil estimasi menggunakan tiga model penelitian
dengan metode ECM menunjukkan bahwa dalam jangka pendek variabel
ekonomi makro dan ekonomi mikro secara bersama-sama signifikan terhadap
volatilitas Indeks Saham LQ45. Secara parsial variabel nilai tukar, volume
perdagangan, EPS, PBV, DER, dan ROE berpengaruh signifikan, sedangkan
inflasi, BI Rate, dan PDB tidak signifikan. Berdasarkan analisis ARCH-GARCH,
model yang pertama mengandung unsur ARCH dan GARCH, model yang kedua
hanya memiliki unsur ARCH, dan model yang ketiga tidak mengandung unsur
ARCH. Selain itu hasil penelitian menunjukkan bahwa volatilitas Indeks Saham
LQ45 yang terjadi tinggi dan berlangsung terus-menerus.
Kata Kunci : Volatilitas Indeks Saham LQ45, variabel ekonomi makro (nilai
tukar, inflasi, BI Rate, PDB, volume perdagangan), variabel
ekonomi mikro (EPS, PBV, DER, ROE), Error Correction Model
(ECM), ARCH-GARCH.
ABSTRACT
This research aims to know and analyze the influence of macro-economic and
micro-economic variable toward volatility Index LQ45 shares. Macro-economic
variables in this research are the exchange rate, inflation, BI Rate, Gross Domestic
Product (GDP) and trade volume , while the micro-economic is earning Per Share
(EPS ), Price to Book Value (PBV), Debt to Equity Ratio (DER), and return On
Equity (ROE ). Data used in this research was time-series data in research
periode of January 2009 until September 2014. Data analysis method used in this
research was desktiptif quantitative analysis method by using three models , the
first is macro-economic and micro-economic variable analyzed together against
volatility Index LQ45, second model is macro-economic variables to volatility
Index LQ45 shares, and the third model was micro-economic variables to
volatility Index LQ45 shares.
The methode used to see the influence between dependent variable and
independent variables was error correction Model ( ECM), while to measure
volatility of Index LQ45 used analysis of ARCH-GARCH. Result of the
estimation by using three research models with ECM method shows that in the
short-term, both macro-economic and micro-economic variable together
significant to Share Index LQ45 volatility. Partialy, exchange rate, trade volume,
EPS, PBV, DER, and ROE significantly affect, while inflation, BI Rate, and
Gross Domestic Product does not significantly affect. Based on the analysis
of ARCH-GARCH, the first model contains elements ARCH and GARCH, the
second model have only elements ARCH, and third model that does not contain
elements ARCH. In addition, results of the study showed that volatility Index
LQ45 relaticely high and keep going.
Key words : Volatility Index LQ45, macro-economic variables, ( Exchange rate,
inflation, BI Rate, Gross Domestic Product, trade volume), microeconomic
variables (EPS, PBV, DER, ROE), error correction
Model (ECM), ARCH-GARCH.
