conditional copula-garch methods for value at risk of portfolio: the case of tehran stock exchange market

ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...

Market Portfolio Efficiency and Value Stocks

In this journal, Best, Best and Yoder (2000) recently demonstrated that portfolios of US value stocks dominate portfolios of US growth stocks in terms of second-order stochastic dominance (SSD). However, we cannot conclude from this finding that the market is SSD inefficient, because market portfolio efficiency generally does not require growth portfolios to be efficient.

Value-at-Risk Based Portfolio Optimization

Multiperiod portfolio investment using stochastic programming with conditional value at risk

This paper proposes the portfolio stochastic programming (PSP) model and the stagewise portfolio stochastic programming (SPSP) model for investing in stocks in the Taiwan stock market. The SPSP model effectively reduces the computational resources needed to solve the PSP model. Additionally, the conditional value at risk (CVaR) is used as a risk measure in the models. In each period of investme...
