MENENTUKAN PORTOFOLIO OPTIMAL MENGGUNAKAN MODEL CONDITIONAL MEAN VARIANCE
When the returns of stock prices show the existence of autocorrelation and heteroscedasticity, then conditional mean variance models are suitable method to model the behavior of the stocks.

Conditional Variance Forecasts for Long-Term Stock Returns [PDF]
In this paper, we apply machine learning to forecast the conditional variance of long-term stock returns measured in excess of different benchmarks, considering the short- and long-term interest rate, the earnings-by-price ratio, and the inflation rate ...

Common Persistence in Conditional Variances [PDF]
Summary: Since the introduction of the autoregressive conditional heteroskedastic (ARCH) model by the second author [ibid. 50, 987-1007 (1982; Zbl 0491.62099)], numerous applications of this modeling strategy have already appeared. A common finding in many of these studies with high frequency financial or monetary data concerns the presence of an ...

Mean–variance relationship and uncertainty [PDF]
This study investigates the impact of uncertainty on the mean-variance relationship. We find that the stock market's expected excess return is positively related to the market's conditional variances and implied variance during low uncertainty periods ...

Modeling Realized Variance with Realized Quarticity
This paper proposes a model for realized variance that exploits information in realized quarticity. The realized variance and quarticity measures are both highly persistent and highly correlated with each other.

Modeling the exchange rate of the euro against the dollar using the ARCH/GARCH models [PDF]
The analysis of time series with conditional heteroskedasticity (changeable time variability, conditional variance instability, the phenomenon called volatility) is the main task of ARCH and GARCH models.
