The efficient market hypothesis (EMH) in the weak-form requires that there is no serial correlation between the returns at different times and successive price changes. On the contrary, stock returns displaying statistically significant autocorrelation between observations widely separated in time, or long memory, would weaken the properties derived from martingale models for pricing derivatives and other financial assets. Using spectral regression method, the fractional differencing parameter is estimated using 522 trading days (2 years post-UK general election day) in the London Stock Exchange (LSE). Evidence suggests that, regardless of the political party forming the government and consistent with findings for major capital markets, there is no evidence to suggest that the market is inefficient in the weak form of the efficient market hypothesis.

This article demonstrates how Rule 10b-5 of the 1934 Securities and Exchange Act fails to induce voluntary disclosure. We show that company owners may deter the disclosure policy for their financing decisions. While there is a link between the way in which firms raise external capital and the information which their firms disclose, we show that the transformed reaction of disclosure is the signal for the company's financing policy.

The article examines long memory in equity returns and volatility for South Africa using the ARFIMA-FIGARCH model in order to assess the efficiency of the market. The sample considered encompasses a period of equity market reform in order to ascertain if such reforms promoted efficiency in the market. The results show that volatility exhibits a predictable component in both sample periods, while returns in both sample periods do not. This suggests that equity market reforms had a benign impact on the market.

We use the stochastic volatility model as a basis for investigating the statistical properties of absolute returns as a measure of latent volatility in financial markets. Our results are compared with existing results for squared returns.

R&D, particularly basic research, is generally considered as a public good. It provides positive externalities to other firms. This article investigates rival firms' stock-price responses to an increase in the R&D expenditures of a firm. Examining firms in the pharmaceutical industry, we found that the market valuations of some rival firms benefit from R&D externalities. Moreover, the cross-sectional analysis indicated that R&D-intensive firms benefit immensely from them. From this result, investors might assess that these firms have the full potential to absorb new R&D knowledge.

Employing data from 13 Latin American countries, we find that greater central bank independence is associated with lesser intervention in the foreign exchange market, and also with leaning-against-the-wind intervention. We also find that the structural reforms that occurred in Latin America mostly in the 1990s helped to reduce the need for foreign exchange intervention.

The portfolio management strategy can gain additional wealth from measuring the cost of accounting for events jumps. This study captures the characteristic of jumps on international equities return in the real world. This frame work follows the Das and Uppal (2004) and bridges the gap on the p. 2817. We find, in their study, the problem that exists an expected term in the final solution of compensating wealth. This article also finds some relationship between the jump size and portfolio weights on the risk compensation.

This article examines the factors that are not considered in the Black–Scholes model in determining the price of warrants. Using the outstanding percentage as a threshold variable, we test for the existence of threshold effect in warrant prices. It is shown that for warrants with a low outstanding percentage, an increase in the outstanding percentage will lower the call price. On the other hand, for warrants with high outstanding percentage, the call price is less affected by the outstanding percentage.

We propose a nonparametric method to determine the functional form of the noise density in discrete-time stochastic volatility models of financial returns. Our approach suggests that the assumption of Gaussian noise is often adequate, but we do observe deviations from Gaussian noise for some assets, for instance gold.

The purpose of this article is to identify whether there is a short-term continuation of returns and a long-term reversal of returns in an Australian setting and to subsequently investigate if the Capital Asset Pricing Model (hereafter CAPM) and the Fama and French (1993) three factor model (hereafter FFM) are capable of explaining these anomalies. We find a short-term continuation of returns but not a long-term reversal of returns. We also find that both models fail to explain the short-term continuation in returns. However, the FFM yields higher explanatory power than the CAPM.
