How to Use These CFA Level I Study Notes

This page is the starting point for my CFA Level I study-note archive. The useful way to read the series is not as a stack of facts to memorize, but as a connected set of tools for answering four questions:

1. What does an investment own or promise?
2. Where do its cash flows come from?
3. What risks can change those cash flows or their value?
4. What evidence would make an analyst revise a conclusion?

Those questions connect accounting, economics, valuation, fixed income, equities, derivatives, and portfolio decisions. They also give you a way to test whether you understand a definition instead of merely recognizing it.

Archive context and scope

The underlying material comes from earlier personal class notes that I began publishing here in 2021. This introduction was substantially rewritten in 2026 to make the series useful on its own. The original post was mostly a personal announcement and study schedule; it did not explain the subject or establish clear source boundaries.

This edition is an original synthesis of my archived notes. It is not a transcription of classroom or curriculum text. It is also not an official CFA Institute publication, a complete representation of any current exam, or a substitute for the current curriculum and candidate policies. Topic names, weights, terminology, accounting rules, and exam procedures can change. For an exam decision, verify the current requirements in official CFA Institute materials.

The archive is strongest in financial-statement analysis and fixed income. Other Level I areas are included in this roadmap because they explain how those subjects fit into investment analysis, not because every area already has a finished article here.

A durable topic roadmap

The exact syllabus can change, but the analytical relationships below remain a useful map.

1. Professional judgment and quantitative foundations

Start with ethics and professional standards: an answer is not useful if its evidence, conflicts, or limitations are hidden. Then build the quantitative toolkit used throughout finance—rates of return, the time value of money, probability, sampling, estimation, and hypothesis testing.

Economics adds the setting. Growth, inflation, interest rates, exchange rates, and market structure influence the assumptions used in company and security analysis. The aim is not to predict every macroeconomic move; it is to understand which assumptions matter and how a changed assumption travels through a valuation.

2. Read the business through its reports

Financial statements translate business activity into a structured record. Learn how the balance sheet, income statement, cash-flow statement, and statement of changes in equity connect. Then ask what accounting choices, estimates, or non-cash items stand between reported numbers and the underlying economics.

A practical reading sequence is:

• identify the business model and major revenue and cost drivers;
• reconcile profit with operating cash flow;
• examine working capital, long-lived assets, financing, and taxes;
• calculate ratios only after understanding their components;
• compare results across time and with genuinely comparable firms;
• note where an accounting policy or estimate limits the comparison.

This sequence makes ratios diagnostic tools rather than isolated formulas.

3. Connect securities to cash flows and claims

Corporate-finance decisions explain how a company funds operations and chooses investments. Equity represents a residual claim: shareholders receive what remains after other claims are satisfied. A bond is a contractual claim whose value depends on promised cash flows, timing, discount rates, credit quality, and embedded options.

Derivatives rearrange exposures rather than creating a free return. Alternative investments introduce different combinations of liquidity, valuation, leverage, and governance risk. Across every asset class, use the same discipline: define the claim, map the cash flows, identify the risks, choose a valuation framework, and state the assumptions.

4. Put individual analyses into a portfolio

A security can look attractive alone and still be a poor addition to a portfolio. Portfolio analysis asks how positions interact, how much risk is concentrated in one driver, and whether expected return compensates for risk and cost. This is where diversification, risk measurement, investor constraints, and performance evaluation meet.

The important habit is to move in both directions: from the economy and industry down to a security, and from the security back up to its effect on the whole portfolio.

How to study from each note

Use a note as a compact lesson, not as a final authority. A productive pass has five steps.

1. State the question first. Before reading the explanation, write down what problem the concept is meant to solve.
2. Define the objects. Identify the cash flow, account, security, rate, period, and point of view. Many finance errors are really timing or definition errors.
3. Explain the mechanism in words. If a rate rises or an assumption changes, trace the direction of the effect before reaching for a formula.
4. Work a small example. Change one assumption at a time and explain why the answer moves. A numerical result without an interpretation is incomplete.
5. Record a check and a limitation. Use an independent calculation, reconciliation, unit check, or source comparison. Then write down where the model stops being reliable.

For review, turn headings into questions and answer them without looking. Mix related topics—for example, connect inventory accounting to margins, cash flow, ratios, and valuation—rather than rereading one chapter repeatedly. Revisit mistakes after a delay and keep a short error log that records the faulty assumption, not just the correct answer.

A reusable analysis checklist

When approaching any finance concept in this archive, ask:

• Purpose: What decision or comparison is this concept designed to support?
• Inputs: Which facts are observed, and which are estimates?
• Timing: When do the cash flows, measurements, or obligations occur?
• Mechanism: Why should changing one input affect the result?
• Perspective: Is the conclusion for the issuer, investor, lender, or portfolio manager?
• Risk: Which uncertainty is included, and which is omitted?
• Comparability: Are definitions, periods, accounting policies, and currencies aligned?
• Verification: Can the result be reconciled, recalculated, or checked against a primary source?

If a note cannot answer those questions, treat it as a prompt for further work rather than a completed explanation.

Provenance, corrections, and reader limits

The old notes are starting material, not authority. In this English edition, explanations should be rewritten in original language, examples should identify their assumptions, and corrections should be made openly when an archived statement is incomplete or wrong. This page does not reproduce proprietary curriculum passages or questions. Any brief quotation or borrowed figure needs a clear source and a reason for inclusion.

Because this is an educational archive, it does not provide personalized investment, legal, tax, or accounting advice. A worked example may simplify taxes, transaction costs, liquidity, or regulation to isolate one idea; those omissions should be stated rather than silently carried into a real decision.

Choose one concept from the roadmap, apply the checklist, and finish by writing a short conclusion in your own words: what the concept explains, which assumption matters most, and what evidence could change the answer. That is the commitment worth keeping—study seriously, explain the reasoning, and make each note more useful than the rough archive it came from.
