Opacity and frequency dependence of beta
This paper examines the relationship between opacity and frequency dependence of systematic risk (β), estimated over different horizons using Wavelet Transform, for small and large firms. The findings provide evidence for the frequency-specific nature of opacity and suggest that while opacity is positively related to the frequency dependence of beta for large firms at all frequencies, for small firms the relationship is significant at low (long horizon) and insignificant at higher (short horizon) frequencies.

Currently, a large number of studies are being conducted to improve the accuracy of the developed forecasting methods for the stock market. At the same time, multivariate models based on machine learning methods are increasingly used. Since liquidity indicators have a significant impact on asset pricing, taking them into account can improve the accuracy of ...

I study how (VaR-based) financial constraints affect liquidity and welfare under different structures of the arbitrage industry. When capital is dispersed across competitive arbitrageurs, financial constraints may impair their ability to provide liquidity, lowering other investors' welfare. However, when capital is concentrated among arbitrageurs with market power, introducing constraints can make everyone better off and ...

The efficiency of digital filters in signal processing from a distributed fiber optic sensor (DTS) is evaluated. Improvement of the metrological characteristics of DTS is possible either by improving hardware or the signal processing algorithm. As a rule, the first issue requires large financial investments. Digital filters can significantly improve the characteristics of DTS as ...

This paper presents the empirical liquidity study of Islamic fixed-income securities during 2020–2021. Using bid-ask and Z-spread metrics we demonstrate that the apogee of both, liquidity and credit stresses in international sukuk market is reached in early April 2020. Contrasting results for non-Islamic fixed-income instruments, we show that sukuk credit spreads recover to pre-Covid levels ...

We perform a comprehensive study of different illiquidity effects in the relatively illiquid Russian stock market. Over the period 2010–2020, we apply cross-sectional and time-series regressions using two low-frequency illiquidity proxies: the Amihud ratio and the invariance-implied ratio. The evidence suggests that implicit trading costs influence only the returns of small-capitalization stocks or low size ...

Using high-frequency transaction-level data for liquid Russian stocks, we empirically reveal a joint nonlinear relationship between the average trade size, log-return variance per transaction, trading volume, and the asset price level described by the Intraday Trading Invariance hypothesis. The relationship is also confirmed during stock market crashes. We show that the invariance principle explains a ...

The work is devoted to credit risk modeling of international banks by constructing ordered logistic models of credit ratings assigned by the agencies: Moody’s, Standard & Poor’s, and Fitch ratings. It was demonstrated that mapping the credit ratings into a base scale helps to decrease the possible subjectivity of CRAs and increases models’ forecasting power. ...
