metadata.value: Goal: to assess the efficiency of the Nigerian stock market after the COVID-19 lockdown
  which had substantial impacts on African countries, including their local stock markets.
  Methodology: the empirical study was conducted by employing the GARCH models with
  three different error distributional assumptions with data covering the timeframe from June
  2020 to December 2022. Findings: the results indicate that during the post COVID-19 period,
  the Nigerian stock market demonstrates inefficiency in the weak form but efficiency in the
  semi-strong form. Originality and contribution of the authors: this is the first empirical
  study in Nigeria that presents the comprehensive overview of market efficiency in the post
  COVID-19 period. The authors’ emphasis in the study that the levels of market efficiency are
  independently determined forms; the semi strong form efficiency can be attained without
  week form efficiency. The study emphasise the importance of implementing strict oversight,
  restrictions, and regulations to discourage excessively negative noise (rumour) traders and
  investors from engaging in short selling for profit especially in equities held by institutional
  investors.
