Full Form of EMH
What is EMH?
The Efficient Market Hypothesis (EMH) is a financial theory developed by Eugene Fama in the 1960s, asserting that asset prices fully reflect all available information at any given time. According to EMH, it is impossible to consistently achieve returns that exceed average market returns on a risk-adjusted basis, because price movements are random and driven by new, unpredictable information. The hypothesis is commonly classified into three forms: weak (past prices are irrelevant), semi-strong (all public information is priced in), and strong (even insider information is reflected). In India, EMH is a core concept taught in commerce and finance curricula for CA, CFA, and MBA programs. It is used by analysts and fund managers when evaluating market efficiency, particularly for indices like the Nifty 50 and BSE Sensex. While some studies suggest Indian markets are semi-strong efficient, the presence of behavioral biases and regulatory changes means EMH remains a debated model. Understanding EMH helps students and professionals critically assess investment strategies and the role of fundamental and technical analysis. For competitive exams such as the UGC NET Commerce or RBI Grade B, questions on EMH forms and criticisms frequently appear, making it a high-yield topic.
