How to Think Like Benjamin Graham and Invest Like Warren Buffett

Cunningham, a law professor who edited The Essays of Warren Buffett, wrote this as a bridge between Graham's analytical framework and Buffett's application of it, aimed at readers who want the reasoning rather than formulas.

His organising argument concerns what he calls information anxiety: investors face more data than they can use and less genuine information than they need, and the response is either paralysis or dependence on intermediaries who profit from the dependence. His answer is a framework for deciding what actually matters.

The content covers Graham's core positions on the distinction between investment and speculation, on the margin of safety and on treating shares as fractional business ownership; the critique of efficient market theory and of beta as a risk measure, arguing that risk is the probability of permanent loss rather than price variability; the analysis of financial statements including the specific places where reported figures diverge from economic reality, on which Cunningham's legal and accounting background is useful; the assessment of management on capital allocation and candour; and the valuation approaches available, with an honest treatment of their limits.

He also covers the legal and governance context, including directors' duties, disclosure obligations and what an outside shareholder can and cannot compel, which most investment books omit and which Cunningham is well placed to explain.

The book is derivative by design, since it presents other people's frameworks. Its contribution is the organisation and the legal and accounting depth. Graham and Buffett's own writing remains the primary source.

Corporate-governance scholar and longtime George Washington University law professor; edits The Essays of Warren Buffett and writes on Berkshire and quality investing.

The Essays of Warren Buffett reorganises decades of Berkshire shareholder letters by subject - governance, accounting, mergers, valuation - turning scattered annual commentary into a usable manual. The later books extend the analysis to Berkshire's decentralised structure and to the traits that make a business durable enough to hold for decades.
