This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How to differentiate between mean, median, and mode in a set of investment returns and why the median is crucial when outliers are present. - That standard deviation is the primary measure of an investment's volatility and risk on the Series 65 exam; a higher number means higher risk. - The significance of the normal distribution, where approximately 67% of returns are within one standard deviation and 95% are within two. - The role of the correlation coefficient, from -1 to +1, in measuring how two investments move in relation to each other. - Why combining assets with low or negative correlation is the key to effective portfolio diversification and risk reduction.
