Semi Strong Efficiency Tests

Theory

Semi-strong efficiency tests evaluate whether current market prices instantly and fully incorporate all publicly available information, including regulatory filings, project announcements, and historical price data. In the context of cryptocurrency and derivatives, these assessments determine if market participants can generate excess risk-adjusted returns through technical analysis or fundamental news trading. If markets operate at this level of efficiency, standard trading signals derived from public data sets fail to provide a consistent informational advantage over the broader consensus.
