What does the Efficient Market Hypothesis imply

The Efficient Market Hypothesis (EMH) is a theory in financial economics that states that asset prices fully reflect all available information. Here's what it implies:

1. Share prices are fair: The EMH implies that the price of a share or any other financial asset reflects its true underlying value. This is because the price is determined by all available information, including the knowledge and expectations of all market participants.

2. No room for "over" or "under" pricing: If all information is already incorporated into the price, then it's impossible for an asset to be overpriced or underpriced. The price you see is the fair price.

3. No benefit from expert analysis: If all information is already reflected in the price, then no amount of analysis can give an investor an edge over others. This is because the analysis is based on information that's already known, and therefore already factored into the price.

4. No consistent "beating the market": The EMH implies that it's impossible to consistently achieve higher than average returns. If you do manage to "beat the market", it's down to luck rather than skill or insider knowledge.

5. Random Walk Theory: The EMH supports the random walk theory, which suggests that stock price changes have the same distribution and are independent of each other. So, the past movement or trend of a stock price or market cannot predict its future movement.

In summary, the Efficient Market Hypothesis implies that the market is always fair and it's impossible to outperform it consistently on a risk-adjusted basis.

The Efficient Market Hypothesis (EMH) is a theory in financial economics that states that asset prices fully reflect all available information. This implies several things:

1. Prices are always fair: Since all available information is already incorporated
