Institutional Development and Stock Price Synchronicity: Evidence from China [PDF]

SSRN Electronic Journal, 2013
Abstract Better developed legal and political institutions result in greater availability of reliable firm-specific information. When stock prices reflect more firm-specific information there will be less stock price synchronicity. This paper traces the experience of China, an economy undergoing dramatic institutional change in the last 20 years with

Economic effects of IFRS adoption in Brazil: An empirical analysis of stock price synchronicity [PDF]

, 2014
This study aims to identify the impact of IFRS adoption in stock price synchronicity of Brazilian capital market through its influence on how much and in which way firm-specific information is incorporated by stock prices. There are divergences in the

Stock price synchronicity and public firm-specificinformation

Journal of Financial Markets, 2011
Abstract How stock price synchronicity mirrors firm-specific information has been a subject of much debate. We posit that price synchronicity can be low in either good or bad firm-specific information environments because stock prices incorporate both public and private information.

N and P constrain C in ecosystems under climate change: Role of nutrient redistribution, accumulation, and stoichiometry

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract We use the Multiple Element Limitation (MEL) model to examine responses of 12 ecosystems to elevated carbon dioxide (CO2), warming, and 20% decreases or increases in precipitation. Ecosystems respond synergistically to elevated CO2, warming, and decreased precipitation combined because higher water‐use efficiency with elevated CO2 and higher ...

Evolutionary Game Model of Stock Price Synchronicity from Investor Behavior

Discrete Dynamics in Nature and Society, 2020
Institutional and individual investors are the two important players in the stock market. Together, they determine the price of the stock market. In this paper, an evolutionary game model that contains the two groups of players is proposed to analyze the

Meta-Stock: Task-Difficulty-Adaptive Meta-learning for Sub-new Stock Price Prediction [PDF]

arXiv, 2023
Sub-new stock price prediction, forecasting the price trends of stocks listed less than one year, is crucial for effective quantitative trading. While deep learning methods have demonstrated effectiveness in predicting old stock prices, they require large training datasets unavailable for sub-new stocks.

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

Advanced Functional Materials, EarlyView.
Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Functional activity of peptide ion channels in tethered bilayer lipid membranes: Review

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract Ion transport across biomembranes plays a major role in living cells. This fundamental function is normally carried out by molecules with both a hydrophobic and a hydrophilic side (amphiphilic molecules), which aggregate within the membrane forming a hydrophilic pore (the ion channel) permitting the selective translocation of permeant ions ...

Hierarchical Structure in Financial Markets [PDF]

, 1998
I find a topological arrangement of stocks traded in a financial market which has associated a meaningful economic taxonomy. The topological space is a graph connecting the stocks of the portfolio analyzed. The graph is obtained starting from the matrix of correlation coefficient computed between all pairs of stocks of the portfolio by considering the ...
