Efficient-market hypothesis: History, Research & Products
The efficient-market hypothesis (EMH) is a hypothesis in financial economics that states that asset prices reflect all available information. A direct implication is that it is impossible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information.

How Efficient-market hypothesis connects Entity context
Entity context groups extracted connections by relationship type. Counts show recurrence in the analyzed source; the examples are research signals, not claims about importance.
The extracted context around Efficient-market hypothesis shows recurring relationship patterns in the source. For example, Efficient-market hypothesis → Additional, CAPM, Early, EMH, Fama-French, FF3, Following GJR's, For, Further, Gibbons, GJR, HML, ILLIQ, Modern Portfolio Theory, MOM, Robert Haugen, Roll's, Ross, See, Shanken Another extracted example is Efficient-market hypothesis → At, By, Economist Paul McCulley, EMH, Financial, Financial Analysts Journal, Financial Times, Former Federal Reserve, Great Recession, In, International Organization, It, Jeremy Grantham, June, Laurence, Market, Martin Wolf, Paul Volcker, Roger Lowenstein, Securities Commissions. Use these groups to spot repeated connection types before inspecting the individual relationships.

Important terminology
Frequent words and multi-word phrases across the lead, headings, infobox and body. Useful for terminology coverage.
Use these terms to understand the vocabulary surrounding the topic, not as a checklist for keyword stuffing.
Relationships are represented as Subject → Predicate → Object triples. Confidence describes extraction strength, not the real-world importance of a relationship; lower-confidence rows may be contextual rather than explicit.

Related concept clusters Concept neighborhoods
Concept neighborhoods group terms that sit near one another in the extracted graph. They are useful for discovering adjacent language and context, but proximity does not by itself imply a factual relationship.
The concept neighborhoods around Efficient-market hypothesis bring nearby vocabulary together. In this analysis, examples include Hypothesis, Empirical and Random. Use the clusters to find adjacent concepts and terminology that may deserve separate research.
