Project title: The nexus between investor sentiment and equity market dynamics. A new sentiment indicator approach.

Financing institution: UEFISCDI (Executive Unit for Financing Higher Education, Research, Development and Innovation) / Ministry of Education and Scientific Research

Project code: PN-III-P1-1.1-TE-2019-1702


At the moment, the approaches of investor sentiment in the literature are limited to either regressing financial variables based on the principal component analysis or to using semantic web techniques which are meant to capture immediate reactions based on news data. Our key contribution is the construction of an aggregated sentiment indicator based on relevant financial variables, cultural and behavioral factors, and qualitative information extracted from media articles and internet messages. This preliminary investigation will be followed by an extensive research focused on the nexus between the sentiment indicator and the dynamics of European equity markets. In the light of the devastating effects of market crashes and excessive volatility, any topic that addresses irrationality, potentially amplified by the manifestation of contagion between markets, represents a priority research. Under such circumstances, investigating investor sentiment and its impact on the dynamics of equity markets offers valuable information for the policy makers responsible for monitoring the efficiency with which capital is allocated through the stock markets. Moreover, it is important that market regulators understand the network patterns of the European equity markets ensuring that episodes of extreme investor sentiment do not cause price explosions threatening the market stability. In addition, for taking advantage from international diversification, investors need to be aware of how international equity markets are correlated and how similar sentiments influence these correlations.

The foreseen contribution of our research proposal is twofold:

  1. Designing an aggregated sentiment indicator at country level.
  2. Exploring the relationship between investor sentiment and equity market dynamics in Europe.
