Blendas de PEAD: Efeito da concentração de PEAD reciclado e do compatibilizante PEAD-g-MA
Acta Scientiae Et Technicae, 2019 A vasta aplicação do polietileno de alta densidade (PEAD), principalmente no setor de embalagens, confere ao PEAD o lugar entre os plásticos mais produzidos e consumidos no mercado mundial. Devido ao grande descarte e geração de resíduos de PEAD, a importância da reciclagem cresce. A utilização do PEAD reciclado em blendas com o PEAD virgem é uma saída

Brazilian Applied Science Review, 2020 O politereftalato de etileno (PET) é um dos principais constituintes dos resíduos sólidos urbanos. A reciclagem de refugos é um processo estratégico que viabiliza a expansão do mercado de plásticos, podendo gerar novos produtos, além de minimizar o impacto ambiental causado pelo descarte incorreto das embalagens PET.

This paper documents post-earnings announcement drift (PEAD) in corporate bond prices using transaction data. We find a counterintuitive relationship between the drift and trading volume: PEAD is more pronounced for more heavily traded bonds than for less frequently traded bonds. Across markets, PEAD is observed for credit default swaps but ...

The FIN and PEAD Factors: Motivation, Construction, and Availability
SSRN Electronic Journal, 2020This document provides an overview of the FIN and PEAD factors of Daniel, Hirshleifer, and Sun (2020) and describes their motivations, constructions, and availability. Based on investor psychology, Daniel, Hirshleifer, and Sun (2020) propose a theoretically motivated factor model that augments the market factor with two factors that capture long- and ...

This paper examines the association between insider trading during the pre-earnings announcement period and the magnitude of the post-earnings announcement drift (PEAD). Consistent with insiders’ private information being incorporated into prices through their trading, we find PEAD is significantly lower when earnings announcements are preceded by ...

A Survey on Post-Earnings Announcement Drift (PEAD)
2009 6th International Conference on Service Systems and Service Management, 2009This paper summarizes and analyzes the empirical literature on PEAD which has been documented repeat. When viewed as a whole, the evidence summarized here presents a more serious challenge to be efficient markets hypothesis than could have been anticipated a few years ago. So the further research is that how to understand the duration of PEAD.

Explaining the Decline of PEAD: More Arbitrage or Less News?
Journal of Accounting, Auditing & FinancePost-earnings-announcement drift (PEAD) has declined significantly over time. The prevailing explanation for this decline from prior work is an increase in arbitraging activities. We propose a new explanation based on a decline in the informativeness of current earnings news in predicting future earnings news (“signal informativeness”).
