Course overview
What you'll learn
Benjamin Graham's The Intelligent Investor introduced the margin of safety, the distinction between defensive and enterprising investors, and the Mr. Market allegory—foundational concepts that shaped modern value investing. But reading about Graham's principles isn't the same as applying them to actual portfolio decisions or distinguishing speculation from investment in your own behavior. Most people finish the intelligent investor summary with vague ideas about "buying undervalued stocks" without knowing how to calculate intrinsic value or structure a defensive portfolio.
This course makes you work with Graham's frameworks through case studies analyzing real companies using his valuation criteria, flashcards drilling the difference between investment-grade bonds and speculative securities, podcast episodes debating whether Graham's principles hold in modern markets, and written assignments where you construct defensive and enterprising portfolios with AI feedback on your margin-of-safety calculations. You'll practice identifying Mr. Market's emotional swings in historical market data and apply Graham's chapter-by-chapter discipline to contemporary investment scenarios.
This is for anyone who wants to move beyond passive reading and actually think like an intelligent investor—whether you're building your first portfolio, refining your investment philosophy, or studying the intellectual foundations of value investing. No prior finance expertise required, but you should be willing to engage with numerical examples and case-based reasoning.
Course curriculum
8 modules, designed for mastery
Investment vs. Speculation: Graham's Foundational Distinction and the Margin of Safety
~60 minUnderstand Graham's precise definition of investment (promising safety of principal and adequate return) versus speculation, and learn to calculate and apply the margin of safety concept to real securities. Practice identifying which activities cross the line into speculation.
The Defensive Investor's Portfolio: Stocks, Bonds, and the 50-50 Formula
~75 minBuild a defensive portfolio using Graham's allocation principles, understanding when to rebalance between stocks and bonds based on market conditions. Apply his criteria for selecting investment-grade bonds and common stocks that meet defensive standards.
Mr. Market and the Psychology of Price Fluctuations
~50 minInternalize Graham's Mr. Market allegory by analyzing historical market episodes where emotional swings created opportunities. Learn to distinguish between price volatility and true investment risk, practicing the mental discipline to ignore or exploit Mr. Market's moods.
The Enterprising Investor: Graham's Criteria for Stock Selection and Special Situations
~80 minApply Graham's quantitative screens for enterprising investing—examining P/E ratios, debt-to-equity, current ratios, and earnings stability. Work through case studies identifying undervalued stocks using his seven statistical requirements and evaluate special situations like workouts and arbitrages.
Security Analysis: Calculating Intrinsic Value and the Earnings Multiplier
~65 minLearn Graham's approach to valuing common stocks through earnings power, asset value, and the appropriate multiplier. Practice calculating intrinsic value for real companies and determining whether current market prices offer an adequate margin of safety.
The Investor and Market Fluctuations: Timing, Pricing, and Dollar-Cost Averaging
~55 minExamine Graham's skepticism of market timing and his case for dollar-cost averaging. Analyze historical data to see how systematic purchase plans perform versus attempts to buy low and sell high, and understand when portfolio rebalancing makes sense.
Inflation, Earnings, and Dividend Policy: Evaluating Management and Corporate Performance
~70 minApply Graham's framework for evaluating management quality through dividend policy, capital allocation, and accounting practices. Understand how inflation affects investment returns and practice identifying companies with sustainable earnings power.

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.”

“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.”

FAQ
Frequently asked questions
No. The course presents Graham's concepts from the ground up and works through them interactively. That said, if you've already read the book, this course will help you move from theoretical understanding to practical application—you'll work with the frameworks rather than just recognize them.
The course directly addresses this question through podcast debates and case studies examining whether Graham's principles apply to contemporary investing. You'll analyze both the enduring logic of the margin of safety and the practical challenges of applying 1949-era screens to today's markets, including the rise of passive investing.
No. Graham himself emphasized that most investors should be defensive, not enterprising. This course teaches you his disciplined framework for thinking about investment versus speculation, understanding value, and avoiding costly mistakes—not a get-rich-quick stock-picking system. You'll learn when enterprising strategies might be appropriate and when they're not.
