A N-Assets Efficient Frontier Guideline For Investments Courses

This article provides directions that allow instructors and students to build an efficient frontier for investments courses. Our step-by-step approach intends to substantially reduce or eliminate the problems in combining the steps of downloading from the internet and use the data  to build the efficient frontier and the capital market line, when short sales are present or not. In a less restricted theoretical framework, the approach can be applied to any subset of assets.&nbsp

Long Term Inter- And Intra-Regional Stochastic Trends To Middle East And North African Capital Markets

This paper investigates the contribution of Middle East and North African (MENA) capital markets to global strategic asset allocation. Eleven MENA stock markets are examined from January 1st, 1990 to December 30th, 2001. Cointegration studies are conducted on daily, weekly and monthly stock market index price to investigate long-term market linkages. Our results indicate few pairwise stochastic trends between markets, but no common long-term co-movements. We suggest that MENA markets provide diversification potentials for the global investor and should not be treated as a block for global strategic asset allocation purposes

On the Pricing Of Chinese Stocks

This study identifies the leading risk attributes to Chinese stock returns. We demonstrate that the forecasting ability of a multifactor expression that includes micro (fundamental) risk factors conditioned by time-varying macro global and local risk factors is significantly superior to the forecasting ability of simpler nested unconditional models. We conclude that micro and macro local and global risks are instrumental in describing the return-generating process of Chinese equities. Using an attribution analysis, we further show that the valuation of Chinese equities is largely conditioned by expected changes in local and global macro risks, and less by unconditional micro risk premiums

Dynamical amplification of phase conjugation using a modulated optical feedback in a Nd:YVO_4 laser

International audienceWe demonstrate an efficient dynamical amplification of phase conjugation in the gain medium of a diode-pumped Nd3+:YVO4 solid state laser via excitation of its relaxation oscillations. Consequently, enhancement in the modulated amplitude of the phase conjugate wave is observed with up to +30 dB compared to classical homodyne approach
