This video dives into the concept of Efficient Market Hypothesis (EMH), a topic that many finance students find challenging. We break down the three forms of market efficiency: weak, semi-strong, and strong, using intuitive graphs and visual aids. You'll learn how historical, public, and private data influence stock prices in each form and what this means for techniques like technical analysis and insider trading. The video concludes with five practice questions to solidify your understanding, helping you prepare for exams and master EMH concepts with confidence.
