Effective Transfer Entropy Approach to Information Flow Among EPU, Investor Sentiment and Stock Market

Frontiers in Physics, 2020
In contrast to the traditional view that economic policy affects investor sentiment and eventually causes stock price fluctuations, we reveal that investor sentiment is a reflection of both economic policy and stock market information. This article first

How information technologies shape investor sentiment: A web-based investor sentiment index

Borsa Istanbul Review, 2019
Este artículo propone un nuevo indicador de sentimiento del inversor que combina el uso del principal componente de análisis con búsquedas en web. Esta propuesta provee de significado económico a variables subyacentes, una sólida estructura de factores y reduce el ruido de las búsquedas en web comparado con otros indicadores de sentimiento basados en ...

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

Advanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Investor Sentiment Measures

, 2004
Our paper examines two potential proxies for investor sentiment - the closed end fund discount (CEFD) and consumer confidence (CC). We can validate these proxies against a recently available more direct proxy for investor sentiment from UBS/Gallup. We find that the CEFD has no correlation with the UBS/Gallup survey, while the consumer confidence index ...

Adaptive Twisting Metamaterials

Advanced Materials, EarlyView.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Relative investor sentiment

International Review of Economics & Finance
We propose a new investor sentiment index by estimating the differences between moments from realized stock returns and option-implied moments. Validating the Relative Investor Sentiment index, we show that the index is correlated with other proxies, exhibits known patterns of stock market reactions to sentiment shocks, is stronger for hard-to ...
