Benjamin Graham, the father of value investing and mentor to Warren Buffett, first published The Interpretation of Financial Statements in 1937 as a practical companion to his monumental work, Security Analysis. While his more famous books delve into deep investment philosophy, this guide offers a concise, "boots-on-the-ground" manual for deciphering the actual numbers that define a company's health.

For decades, the PDF of this book has circulated quietly in online forums, Discord servers, and self-taught investor libraries. To the uninitiated, it looks like an outdated accounting primer. To the initiated, it is a masterclass in cutting through corporate noise to find tangible truth.

• FIFO (First In, First Out): Makes profits look higher during inflation (because you are selling old, cheap inventory at new, high prices).
• LIFO (Last In, First Out): Makes profits look lower, but saves taxes. Graham teaches you to recast the financials to see the "true" economic profit, not just the reported accounting profit.
