Q.3) Write short notes on:

a) Post-earning drift in economics (GS – 3)

  • Post-earning drift refers to the tendency among stocks and other financial securities to offer abnormal returns to investors even weeks or months after an earnings surprise.
  • A stock, for instance, might continue to rise strongly for a number of weeks after the underlying company posts excellent results.
  • This happens because it takes time for investors to fully incorporate all the relevant fresh information about a stock into its price.
  • The prevalence of the drift is considered to be a refutation of the famous academic hypothesis that markets efficiently price all securities at all times.

b) Replication crisis in science and technology (GS – 3)

  • Replication crisis refers to the failure of many scientific studies to replicate the results of previous studies.
  • It is usually attributed to various errors and biases in the methodology used by scientists to conduct their experiments on a subject.
  • Others, however, have attributed the replication crisis to the inherent impossibility of arriving at the real truth in certain fields of study using scientific methods.
  • This may be due to randomness.
  • Since some major scientific theories have been based on data that have failed to be replicated by follow-up studies, many scientists have been forced to rethink their previous conclusions.
