## Efficient Market Hypothesis

The efficient market hypothesis (EMH) posits that asset prices reflect all available information, making it impossible to consistently achieve returns that outperform the market. In an efficient market, any new information is instantly incorporated into the price, leaving no room for profitable arbitrage or trading strategies based on historical data.

While the strong form of EMH is often debated, especially in the context of cryptocurrency's extreme volatility and sentiment-driven price action, it serves as a foundational concept in financial theory. Many traders believe that while markets may not be perfectly efficient, they are highly competitive, requiring advanced quantitative models and proprietary data to find an edge.

Understanding the degree of market efficiency is vital for setting realistic investment expectations and choosing appropriate trading strategies. It forces participants to consider whether their edge comes from superior information, speed, or risk-taking capacity.
