Course overview
What you'll learn
Burton Malkiel's A Random Walk Down Wall Street argues that markets are largely efficient, that stock prices follow an unpredictable path, and that most active managers can't beat a simple index fund after fees. The book walks through the Firm-Foundation and Castle-in-the-Air theories, tears apart technical and fundamental analysis, and introduces the Efficient Market Hypothesis in its weak, semi-strong, and strong forms. But reading a summary of these ideas doesn't prepare you to apply them when your neighbor brags about their stock picks, when a financial advisor pitches an actively managed fund, or when you're tempted to time the market during a downturn. This course forces you to work with Malkiel's frameworks through real scenarios, numerical exercises, and structured debates.
You'll analyze historical bubbles through the lens of behavioral finance, calculate the compound drag of expense ratios using spreadsheet assignments with AI feedback, and listen to podcast episodes that pit the case for indexing against counterarguments from active investing advocates. Flashcards test your recall of terms like beta, standard deviation, and dollar-cost averaging. Case studies ask you to evaluate actual fund performance data and construct portfolios using Malkiel's age-based asset allocation guidance. Written assignments require you to articulate why a random walk down wall street summary isn't enough—you need to internalize the math, the psychology, and the discipline required to stick with passive strategies during market turbulence.
This course is for anyone building an investment portfolio, questioning whether they should pay for active management, or trying to separate evidence-based advice from financial noise. You don't need an economics degree—just a willingness to engage with numbers, challenge your intuitions, and think probabilistically about long-term wealth.
Course curriculum
8 modules, designed for mastery
The Firm-Foundation and Castle-in-the-Air Theories: Two Frameworks for Valuing Stocks
~60 minUnderstand the intrinsic value approach versus the greater fool theory. Apply both lenses to historical case studies and identify which worldview drives your own investing instincts.
Anatomy of Historical Bubbles: Tulip Mania, the South Sea Bubble, and the Dot-Com Crash
~75 minExamine Malkiel's chronicles of market madness through behavioral finance concepts. Practice spotting the warning signs of speculation and irrational exuberance in contemporary markets.
Technical and Fundamental Analysis Under the Microscope: Why Patterns and P/E Ratios Fall Short
~50 minTest the claims of chartists and security analysts against empirical evidence. Work through exercises that reveal why past price movements and earnings forecasts fail to predict future returns consistently.
The Efficient Market Hypothesis: Weak, Semi-Strong, and Strong Forms Explained
~65 minBreak down what each form of market efficiency claims and what evidence supports or contradicts it. Debate whether markets are efficient enough to justify passive investing in a podcast-style discussion.
Index Funds and the Arithmetic of Active Management: Calculating the Cost of Underperformance
~80 minRun the numbers on expense ratios, turnover costs, and tax drag. Use spreadsheet assignments to see how a 1% annual fee compounds into a six-figure difference over decades.
Modern Portfolio Theory: Diversification, Beta, and the Capital Asset Pricing Model
~70 minApply Markowitz's diversification principles and the CAPM to construct portfolios with different risk-return profiles. Calculate betas and understand what systematic risk you can't diversify away.
Behavioral Finance and Market Anomalies: When Psychology Overrides Efficiency
~55 minExplore overconfidence, herd behavior, and loss aversion as challenges to the EMH. Evaluate whether anomalies like the January effect or momentum justify active strategies or are statistical noise.
Building Your Lifecycle Portfolio: Asset Allocation, Rebalancing, and Dollar-Cost Averaging
~85 minUse Malkiel's age-based allocation rules to design a portfolio strategy. Practice rebalancing scenarios and assess whether dollar-cost averaging truly reduces risk or just smooths emotional discomfort.

Everything you need
Six learning formats, one complete experience
Every module delivers content across multiple formats — each chosen for a specific learning science reason.
AI-Generated Podcasts
Two voices — an expert and a curious learner — break down complex topics in engaging conversations. Listening activates different cognitive pathways than reading, deepening comprehension.
Structured Key Concepts
Clear, pedagogically-framed core knowledge organized for progressive understanding. Each concept builds on the last, creating a coherent mental model.
Real-World Case Studies
Applied examples from actual scenarios show how theory works in practice. Case-based learning bridges the gap between knowing a concept and using it.
Interactive Flashcards
Active recall — testing yourself — is proven to improve retention by 50%+ compared to passive review. Flashcards make retrieval practice effortless.
Quizzes & Assessments
Multiple-choice questions with detailed explanations test understanding and reveal knowledge gaps before you move on. Mastery-based progression ensures nothing is skipped.
Written Assignments
Writing forces deeper processing than multiple choice. Synthesize your learning by applying concepts to realistic scenarios, with instant AI-powered feedback on your analysis.
Built on learning science
Every format is here for a reason
Erudia courses combine five proven learning methods into one seamless experience — so knowledge sticks, not just passes through.
Spaced Exposure
Content revisited across multiple formats — audio, text, flashcards, quizzes — reinforces memory through varied repetition. Each encounter strengthens the neural pathway differently.
Retrieval Practice
Flashcards and assessments force active recall — proven to improve retention by 50%+ versus passive reading. Every quiz is a memory-strengthening event.
Synthesis Through Writing
Written assignments require deeper processing than multiple choice. When you explain a concept in your own words, you discover what you truly understand and what you don't.
Multi-Format Learning
Audio, reading, case studies, and interactive practice mirror how people naturally absorb complex information. Each format activates different cognitive pathways, building richer understanding.
Mastery-Based Progression
You can't skip ahead until you've demonstrated understanding. This isn't arbitrary — it's how lasting learning works. Each module builds on the foundations laid by the previous one.
What learners are saying
Real courses, real feedback
“I expected a surface-level overview, but the course actually got into altitude-specific soil biology, frost-resilient guild planting, and water management for mountain terrain. The case studies were specific enough that I could apply them to my own site. The podcast episodes were perfect for listening while working in the garden.”

“I've read the book twice, so I was skeptical a course could add anything. It did. The module on counter-strategies completely changed how I think about defensive positioning, and the written assignments forced me to actually apply the laws to situations I'm dealing with at work — not just passively absorb them.”
Mauritz Burenius
Author of Never Piss Off HR · The 48 Laws of Power
“This covered territory I haven't seen in any other course — residual valuation models for streaming libraries, probabilistic forecasting for franchise IP, portfolio construction across film, TV, and gaming assets. The quizzes caught gaps in my understanding I didn't know I had. Genuinely useful for anyone working in media finance.”
