What is another word for efficient market hypothesis?
Pronunciation: [ɪfˈɪʃənt mˈɑːkɪt ha͡ɪpˈɒθəsˌɪs] (IPA) 
The Efficient Market Hypothesis (EMH) is a popular concept in finance that suggests financial markets are perfectly efficient, meaning that all relevant information is immediately reflected in the prices of securities. Some synonyms for EMH include the Random Walk theory, the Efficient Markets theory, and the Informational Efficiency theory. These terms all describe the idea that stock prices follow a random and unpredictable pattern, and that it is impossible to consistently outperform the market through analysis or insider knowledge. While the EMH has its critics, it continues to be a widely accepted concept in the finance world, influencing investment strategies and financial research.
