Model Threshold Generalized Autoregressive Conditional Heteroscedasticity (TGARCH) merupakan model yang digunakan untuk memodelkan volatilitas yang memiliki efek asimetris. Tujuan penelitian ini adalah memodelkan dan meramalkan volatilitas IHSG menggunakan model TGARCH untuk sepuluh periode ke depan. Data yang digunakan adalah data return IHSG penutupan mingguan dari tanggal 8 Februari 2009 sampai dengan 10 Februari 2019. Penelitian ini diawali dengan pembentukan model Box Jenkins. Residual model Box Jenkins terbaik digunakan untuk mendeteksi heteroskedastisitas menggunakan uji ARCH-LM. Data residual yang memiliki heteroskedastisitas dimodelkan ke dalam model GARCH. Residual model GARCH dan residual model Box Jenkins digunakan untuk memeriksa pengaruh asimetris, yaitu dengan melakukan korelasi silang pada kedua residual model tersebut. Berdasarkan hasil korelasi silang yang dilakukan didapatkan adanya pengaruh asimetris terhadap volatilitas, sehingga digunakan model TGARCH untuk mengatasinya. Model TGARCH terbaik dalam penelitian ini adalah TGARCH(1,1) berdasarkan nilai Akaike Information Criterion (AIC) dan Schwarz Criterion (SC) terkecil. Model TGARCH(1,1) digunakan untuk meramalkan volatilitas IHSG. Hasil peramalan volatilitas yang diperoleh untuk sepuluh periode ke depan mengalami peningkatan sebesar 0,000015 sampai dengan 0,000029.Kata Kunci: Asimetris, GARCH, TGARCH

Investment can be defined as an activity to postpone consumption at the present time with the aim to obtain maximum profits in the future. However, the greater the benefits, the greater the risk. For that we need a way to predict how much the risk will be borne. Modelling data that experiences heteroscedasticity and asymmetricity can use the Asymmetric Power Autoregressive Conditional Heteroscedasticity (APARCH) model. This research discusses the time series data risk analysis using the Value at Risk-Asymmetric Power Autoregressive Conditional Heteroscedasticity (VaR-APARCH) model using the daily closing price data of Bitcoin USD period January 1 2019 to 31 December 2019. The best APARCH model was chosen based on the value of Akaike's Information Criterion (AIC). From the analysis results obtained the best model, namely ARIMA (6,1,1) and APARCH (1,1) with the risk of loss in the initial investment of IDR 100,000,000 in the next day IDR 26,617,000. The results of this study can be used as additional information and apply knowledge about the risk of investing in Bitcoin with the VaR-APARCH model.

Era globalisasi menyebabkan banyak perubahan dalam pengembangan sistem ekonomi, salah satunya adalah data keuangan. Tujuan dari penelitian ini ialah untuk mendapatkan model terbaik dalam menganalisis dan memprediksi data penutupan harga saham mingguan untuk PT Adhi Karya (Persero) Tbk dari September 1990 hingga Januari 2016 yang berjumlah 1314 data. Model yang digunakan adalah model Asymmetric Power Autoregressive Conditional Heteroscedasticity (APARCH). Model terbaik dipilih berdasarkan Akaike Info Criterion (AIC) dan Schwarz Criterion (SC). Dari hasil analisis diperoleh model terbaik yaitu APARCH (1,1) dengan ARIMA (1,1,1) sebagai model rerata bersyarat. Hasil peramalan untuk 7 periode berikutnya menunjukkan bahwa perkiraan tersebut dalam interval kepercayaan 95% yang berarti bahwa hasil peramalan menggunakan model ini dapat dipercaya dalam kisaran 95%.   The era of globalization led to many changes in the development of economic systems, one of which is the data that is financially. The purpose of this study is to get the best model in analyzing and predicting weekly stock price closing data for PT Adhi Karya (Persero) Tbk from September 1990 to January 2016 which amounted to 1314 data. The model used is the Asymmetric Power Autoregressive Conditional Heteroscedasticity (APARCH) model. The best models are selected based on Akaike Info Criterion (AIC) and Schwarz Criterion (SC).

The Generalized Autoregressive Conditional Heteroscedasticity (GARCH) modelhas been widely used in time series forecasting especially with asymmetricvolatility data. As the generalization of autoregressive conditionalheteroscedasticity model, GARCH is known to be more flexible to lag structures.Some enhancements of GARCH models were introduced in literatures, among themare Exponential GARCH (EGARCH), Threshold GARCH (TGARCH) andAsymmetric Power GARCH (APGARCH) models. This paper aims to compare theperformance of the three enhancements of the asymmetric volatility models bymeans of applying the three models to estimate real daily stock return volatilitydata. The presence of leverage effects in empirical series is investigated. Based onthe value of Akaike information and Schwarz criterions, the result showed that thebest forecasting model for daily stock return data is the APARCH model.Keywords: Volatility, GARCH, TGARCH, EGARCH, APARCH, AIC and SC.

Many models have been developed to model, estimate and forecast financial time series volatility, amongst which are the most popular autoregressive conditional heteroscedasticity (ARCH) model introduced by Engle (1982) and generalized autoregressive conditional heteroscedasticity (GARCH) model introduced by Bollerslev (1986). The aim of this paper is to determine which type of ARCH/GARCH models can fit the best following cryptocurrencies: Ethereum, Neo, Ripple, Litecoin, Dash, Zcash and Dogecoin. It is found that the EGARCH model is the best fitted model for Ethereum, Zcash and Neo, PARCH model is the best fitted model for Ripple, while for Litecoin, Dash and Dogecoin it depends on the selected distribution and information criterion.

Autoregressive Conditional Heteroscedasticity

Many experts and scholars at home and abroad have studied this topic in depth, laying a solid foundation for the research of financial market prediction. At present, the mainstream prediction method is to use neural network and autoregressive conditional heteroscedasticity to build models, which is a more scientific way, and also verified the feasibility of the way in many studies. In order to improve the accuracy of financial market trend prediction, this paper studies in detail the neural network system represented by BP and the autoregressive conditional heterogeneous variance model represented by GARCH. Analyze its structure and algorithm, combine the advantages of both, create a GARCH-BP model, and transform its combination structure and optimize the algorithm according to the uniqueness of the financial market, so as to meet the market as much as possible Characteristics. The novelty of this paper is the construction of the autoregressive conditional heteroscedasticity model, which lays the foundation for the prediction of financial market trends through the construction of the model. However, there are some shortcomings in this article. The overall overview of the financial market is not very clear, and the prediction of the BP network is not so comprehensive. Finally, through the actual data statistics of market transactions, the effectiveness of the GARCH-BP model was tested, analyzed and researched. The final results show that model has a good effect on the prediction and trend analysis of market, and its accuracy and availability greatly improved compared with the previous conventional approach, which is worth further study and extensive research It is believed that the financial market prediction model will become one of the mainstream tools in the industry after its later improvement.
