The empirical results find that there are many lower bound arbitrage opportunities in China copper futures market from August 8th, 2003 to August 16th, 2005, Concretely, no-arbitrage opportunity is dominant and lower bound arbitrage is narrow in normal market segment. Lower bound arbitrage almost always exists with huge magnitude in inverted market segment. There is basically no-arbitrage in normal market because spot volume is enough, so that upper or lower bound arbi- trage can be realized, There is mostly lower bound arbitrage in inverted market because spot volume is lack.展开更多

This study examines whether the January effect still exists and if it does, whether arbitrageurs exploit it. We find that the January effect is still persistently significant. Furthermore, we find that arbitrageurs appear to exploit the January effect, especially in good market years when the number of losing firms is limited and are therefore more easily identifiable. We also find that the January effect tends to be higher for losing stocks with high arbitrage costs relative to those with low arbitrage costs.展开更多

The main result gives a sufficient condition on stock prices for the existence of such asymptotic arbitrage.As a consequence, she gives a new proof of a conjecture of F?llmer and Schachermayer.展开更多

The news impact curve of copper future price fluctuation respectively introduced funds speculation position and arbitrage position was given, and the result is consistent with the empirical study conclusion. The results show that investment funds are not the factor that causes copper future price fluctuation, but can reduce the copper future price fluctuation; the copper future price fluctuation is more sensitive to negative information, and ftmd speculative positions can reduce asymmetric effect of copper price fluctuation, while fimds arbitrage position influences less.展开更多

This study derives an extension of the Black-Scholes model and recovers the real drift of binary call options from their market prices. For space-dependent real drift, we obtain stable linearization and an integral equation. We also find that using market prices of options with different strike prices enables us to identify the term structure of the real drift. Results demonstrate that our new approach can confirm the existence of arbitrage opportunities in a binary option transaction.展开更多

Meanwhile, this paper validates the mean reversion time sequence for consecutive 54 week data of fund market. The result indicates that this model can effectively prove that Chinese close-end fund market follows the biased random walk. The research also proves that the fund discount does have mean reversion tendency and averagely the fund with high discount has a higher excess yield than that of the fund with low discount. The mean excess yield and the ratio between discount rate deviation and standard deviation demonstrate a descending relationship. The optimum investment period based on "mean reversion" is one month. Consequently this model provides a new arbitrage method through the discount of close-end fund.展开更多

Secondly, it explores financial derivative system in global economy. Thirdly, this study explores world money notion of M. Keynes. Keynes presented world money concept in 1944, in Bretton Woods Talk. His notion may be applied through global GDP today. Assumption of this study is that world money may finance debt payment of nations, and it finances balanced payment deficit of economies, because capitalism of modem economy requires money to run business system. Uysal (2016) presented World money Notion and 2008 Process in conference of 1 lth International Silkroad in Tbilisi, Georgia. Uysal (2015, 2016) discussed World Money concept in the conference with assumption that it may increase demand in global economy. This study is based on case study, which is 2008 Global Crise.

The authors use data on five developed countries and five emerging countries as well as data on the Tunis Stock Exchange (TSE) after the reforms. The results show that the correlations between emerging markets returns and developed markets returns are very low and sometimes negative. Conditional arbitrage pricing theory (APT) as well as conditional CAPM has low predictive power for emerging markets than that for developed markets. Finally, following the financial reforms, Tunisian financial markets have became more and more integrated into the international market (excess returns and unconditional beta consistent with predictions). However, conditional APT does not accurately explain Tunisian market returns. This study confirms the unavailability of an accurate modelling technique of the TSE structure.展开更多

文摘On the basis of fractal theory, one of the nonlinear theories, this paper studies the validity of Chinese fund market fractal time sequence through Hurst exponent, calculates the H value and proposes a new close-end fund mean reversion model. Meanwhile, this paper validates the mean reversion time sequence for consecutive 54 week data of fund market. The result indicates that this model can effectively prove that Chinese close-end fund market follows the biased random walk. The research also proves that the fund discount does have mean reversion tendency and averagely the fund with high discount has a higher excess yield than that of the fund with low discount. The mean excess yield and the ratio between discount rate deviation and standard deviation demonstrate a descending relationship. The optimum investment period based on "mean reversion" is one month. Consequently this model provides a new arbitrage method through the discount of close-end fund.
