The 2026 Question: Is Graham Still Useful?
Every few years someone writes a thinkpiece announcing that value investing is dead. The last decade — with mega-cap tech dominating returns, zero interest rates inflating growth multiples, and meme stocks embarrassing a generation of disciplined analysts — gave the obituary writers more material than usual. Behind every obituary sits the same question: is Benjamin Graham's 1934 book still useful in a market that bears no resemblance to the one he wrote in?
My honest answer, as a working value investor who has read Security Analysis cover to cover and who runs a real book of positions today: yes, but with a three-layer adaptation. The framework is intact. The implementation is different. And in certain corners of the market — especially preferred shares, distressed debt, and situations defined by contractual cash flows rather than growth expectations — Graham is more useful than he has been in decades.
This page is structured the way I actually think about the question. Section one — what still works unchanged. Section two — what has genuinely changed and requires modern adaptation. Section three — a concrete case study applying Graham's framework to my live position in Fannie Mae and Freddie Mac junior preferred shares. If you read only one section, read the case study. The framework only matters when you see it applied to real capital.
One note before we begin. If you have not yet read Graham at all, start with the primer pages — a short overview of Security Analysis and the complete guide to The Intelligent Investor. This page assumes you know the vocabulary.
Part 1: What Still Works Exactly As Written
Six parts of Graham's framework require zero modernization. These are the parts you tattoo on your forearm.
Margin of Safety
The single most important concept in investing and the closest thing to a law of physics in finance. Graham's insistence on buying well below your estimate of intrinsic value is not a stylistic choice — it is error-correction baked into the purchase decision. If you pay 50 cents for a dollar and you are wrong by 20%, you still have 30 cents of cushion. No amount of modernization diminishes this.
Investment vs Speculation
Graham's definition — an investment operation is one which, upon thorough analysis, promises safety of principal and a satisfactory return — still separates the professionals from the gamblers. Every SPAC mania, every zero-day options boom, every crypto cycle is a failure to honor this distinction. Modern markets have more sophisticated gambling instruments than 1934, but the line between analysis and hope has not moved.
Qualitative Analysis of Management
Graham asked whether management treated shareholders as owners or as a source of funds. In 2026, with stock-based compensation regularly consuming 10-30% of operating income at tech companies and boards approving dilutive secondary offerings at market lows, this question is sharper than ever. A great balance sheet run by a self-dealing CEO is a wealth-destruction machine on a delay.
Temperament Over Intelligence
Graham wrote that the investor's worst enemy is himself. Warren Buffett has repeated this for 70 years. Neither social media nor algorithmic trading nor zero-commission brokerages has changed the fundamental truth: the investor who can hold through a 50% drawdown without selling outperforms the genius who cannot. Temperament is the one edge that does not erode.
Mr Market Is Your Servant
The most famous allegory in investing literature. Mr Market shows up every day offering prices — sometimes euphoric, sometimes despondent — and you are never obligated to trade. In 2026, with 24/7 markets, prediction-market sentiment indices, and push notifications on every price move, the ability to ignore Mr Market is more valuable than it has ever been. This is a psychological framework, not an outdated metaphor.
Preferred and Senior Security Analysis
A huge portion of Security Analysis is devoted to preferred shares, convertible bonds, and other instruments that modern retail investors largely ignore. These securities are where Graham's framework is at its most precise — because they have contractual terms, defined par values, and seniority in the capital stack, you can calculate intrinsic value with much less guesswork than with common equity. This is why my GSE preferred thesis is Graham's framework applied exactly as written.
The pattern: everything Graham wrote about psychology, discipline, and the structural relationship between price and value is eternal. Anything that depends on specific accounting practices, specific interest rates, or specific capital-return conventions needs updating. Keep that division in mind as you read the next section.
Part 2: What Has Changed Since 1934
These are the six areas where a literal reading of Graham will lead you astray in 2026. The principles still apply — but the mechanics require modernization.
Accounting Has Drifted
Graham worked with simpler, more conservative accounting rules. Modern GAAP allows revenue recognition practices, intangible asset capitalization, and 'adjusted' non-GAAP metrics that would have made Graham suspicious. Stock-based compensation, add-backs for restructuring charges that recur every year, and 'adjusted EBITDA' are modern accounting evasions. A Graham analysis in 2026 has to start by unwinding the narrative accounting and reconstructing the real earnings power.
Intangibles Dominate Balance Sheets
In 1934, the biggest companies in America were railroads, steel mills, and utilities — physical asset businesses. Graham's book value analysis worked because book value was close to replacement cost. In 2026, the biggest companies are software, platforms, and networks. A tech company's real assets — brand, code, customer relationships, talent — do not appear on the balance sheet. Tangible book value is often negative for great businesses. You cannot apply Graham's price-to-book rules literally.
Buybacks Replaced Dividends
For Graham, the dividend was the primary evidence that a company was sharing its earnings with owners. In 2026, buybacks are the dominant capital return mechanism for most large US companies, and dividends are secondary. This breaks Graham's dividend-yield analysis. Worse, buybacks at market peaks destroy value — a company that buys back shares at 40x earnings and issues stock-based comp at trough prices is running a value-destruction loop. Modern Graham analysis requires total shareholder yield, net of dilution.
Zero-Rate Era Broke Valuation Benchmarks
Graham's rules of thumb — P/E below 15, dividend yield at least two-thirds of AAA bond yield, current ratio above 2 — were calibrated for an interest-rate world that no longer exists. From 2009 to 2022 the risk-free rate was near zero, which mathematically justified much higher multiples on cash-generating assets. Graham's benchmarks become price-to-book floors rather than literal thresholds. Post-2022 rate normalization is bringing valuations back toward Graham territory in many sectors — but not all.
Information Is Instant and Expensive
In 1934, a Graham-style analyst had an edge simply by reading 10-K filings that most investors ignored. In 2026, every 10-K is parsed by dozens of algorithms within seconds of filing. The informational edge Graham exploited in small-cap net-nets is largely gone in developed markets. What remains is the behavioral edge — being able to own something for five years while others panic in three months. The locus of edge has shifted from information to time horizon.
Derivatives and Structured Products
Graham analyzed stocks, bonds, preferreds, and convertibles. The modern market includes options, futures, swaps, ETFs, leveraged products, inverse products, and derivatives of derivatives. A Graham analysis in 2026 has to understand what is synthetic versus physical, what is leveraged versus cash, and what the counterparty risk looks like. This is an expansion of Graham, not a contradiction — he would have loved the analytical complexity.
The Modernization Layer
Here is how I translate Graham's framework into 2026 practice. Each adaptation preserves the underlying principle but updates the mechanics.
GRAHAM 1934
Graham 1934: Look at reported earnings and average them over a cycle.
MODERN ADAPTATION
Modern: Start with reported earnings, then subtract stock-based compensation, add back non-recurring items that are genuinely non-recurring (not the same 'restructuring charge' every year), and adjust for leases now on balance sheet under ASC 842.
GRAHAM 1934
Graham 1934: Tangible book value is a floor for common stock prices.
MODERN ADAPTATION
Modern: Tangible book is still a floor for asset-heavy businesses, but irrelevant for software and platforms. Use replacement cost of competitive position as the modern proxy.
GRAHAM 1934
Graham 1934: Dividend yield is the primary evidence of shareholder return.
MODERN ADAPTATION
Modern: Total shareholder yield = (dividends + net buybacks) / market cap. Net buybacks means gross buybacks minus stock-based comp issuance. A lot of 'buyback programs' are really comp-dilution offsets.
GRAHAM 1934
Graham 1934: A P/E above 15 is expensive.
MODERN ADAPTATION
Modern: Compare earnings yield (1/PE) against the 10-year Treasury yield. When Treasuries pay 1%, a P/E of 25 is not insane. When Treasuries pay 5%, a P/E of 25 needs growth to justify.
GRAHAM 1934
Graham 1934: Preferred shares are analyzed by dividend coverage and seniority.
MODERN ADAPTATION
Modern: Same framework, still works. This is why I apply it directly to GSE preferreds without modification — the analytical method is intact.
GRAHAM 1934
Graham 1934: Net-net stocks (below net current asset value) are bargains.
MODERN ADAPTATION
Modern: In developed markets, net-nets are mostly value traps. Apply the framework to segments of the market that are still inefficient — preferreds, distressed debt, small international names, conservatorship situations.
The pattern is consistent. Graham's framework is a skeleton. The 2026 analyst has to dress it in the clothing of modern accounting, modern capital structures, and modern rate environments. The skeleton does not change.

Case Study: Applying Graham to GSE Preferred Shares
The framework only matters when you see it applied to real capital. Here is how I use Graham to analyze my live position in Fannie Mae (FNMA) and Freddie Mac (FMCC) junior preferred shares.
Identify the Security
The Fannie Mae and Freddie Mac junior preferred shares (FNMA and FMCC tickers for various series) are cumulative preferreds with stated par values of $25 or $50, issued during normal corporate operations before 2008. The 2008 conservatorship suspended their dividends but did not extinguish the underlying contractual obligations.
Define Intrinsic Value Precisely
Unlike common stocks, the intrinsic value of these preferreds is bounded by the par value. If Fannie and Freddie exit conservatorship and return to shareholder-owned status, these preferreds should trade to par or close to it. That gives a defined upside target. Graham loved this kind of setup because the valuation discipline is built into the security itself.
Calculate Margin of Safety
The junior preferreds have traded between 20% and 60% of par for most of the post-2008 era. When they trade at 30% of par, you have a theoretical 3x upside if they reach par — roughly 70% margin of safety against your intrinsic-value estimate. This is exactly the kind of asymmetry Graham wrote about in Chapter 20 of The Intelligent Investor.
Assess Qualitative Risks
Graham would insist on understanding why the security is cheap. In the GSE case, it is not business impairment — Fannie and Freddie are among the most profitable financial institutions in the world, generating $15-$25 billion in annual earnings. The discount is caused by political risk, legal uncertainty, and the Treasury's senior preferred stock. This is a qualitative, not quantitative, discount.
Evaluate Management and Governance
Graham would look at who controls the enterprise. In 2026 the GSEs are controlled by FHFA as conservator, with Treasury holding senior preferred stock. The fundamental governance question is whether the conservatorship ends on terms that respect the junior preferred claims. The Berkley Insurance jury verdict in 2023 confirmed that courts take these claims seriously, which is additional margin of safety.
Execute with Position Sizing
Graham emphasized that even well-analyzed positions can fail. The correct response is position sizing, not avoidance. I have sized my GSE preferred position as a meaningful but not catastrophic portion of my portfolio — large enough to matter if the thesis works, small enough to survive if it does not. That is Graham's diversification principle applied to a concentrated value idea.
Why this trade is pure Graham
Read Chapter 20 of The Intelligent Investor or the preferred-share chapters of Security Analysis and you will see the exact structure of this trade: contractual claim, deep discount to par, non-economic reason for the discount, operating fundamentals strong, margin of safety enormous.
Graham would not have been surprised that such a setup exists in 2026. He wrote at length about situations where political, legal, or regulatory uncertainty drives prices far below intrinsic value even as the underlying business generates enormous cash flow. Railroad reorganizations in the 1930s, utility holding company dissolutions in the 1940s — he lived through several cycles of exactly this pattern. The GSE conservatorship is the modern version.
If you want the full case I have built on this position, including the jury verdict analysis, the upcoming DC Circuit oral argument, and the position sizing math, start at the Fanniegate hub. Hundreds of articles, all tied to this single thesis.
A Modern Graham Checklist
Here is the checklist I actually run on a position before I commit real capital. It is Graham's framework plus the 2026 adapter layer — think of this as the practitioner's summary of everything above.
- Earnings power. Build an average of 5-10 years of operating income, stripped of non-recurring items but including stock-based comp as a real expense. Is the business actually profitable across a cycle, or only in good years?
- Total shareholder yield. Dividends plus net buybacks (gross buybacks minus stock-based comp dilution), divided by market cap. If this number is negative, shareholders are being diluted. Proceed with caution.
- Balance sheet quality. Check operating leases, pension underfunding, contingent liabilities, off-balance-sheet arrangements. Graham's current ratio and debt-to-equity tests still work but you have to include the hidden liabilities.
- Management quality. Read the last five annual reports and proxy statements. Is compensation aligned with per-share value creation, or with size and growth? Do they buy back stock at peaks and issue at troughs?
- Intrinsic value estimate. Use multiple methods: earnings power x a fair multiple, discounted cash flow at a realistic discount rate, replacement cost for asset-heavy businesses, contractual claim for preferreds and debt.
- Margin of safety. Is the price at least 30-50% below your intrinsic value estimate? If yes, proceed to position sizing. If no, wait for a better price. Never pay full price.
- Qualitative disaster check. What is the scenario in which you lose 80% of your capital? Is it a real risk or a tail risk? Can you survive the drawdown without forced selling?
- Position size. Large enough to matter if the thesis works, small enough to survive if the thesis fails. For conviction value trades, I size at 3-10% of the portfolio per position.

Frequently Asked Questions
Is Security Analysis still relevant in 2026?
Yes, but with adaptations. The framework Graham built in 1934 — margin of safety, qualitative judgment about management, treating Mr. Market as a servant rather than a master, demanding a quantitative cushion before you invest — is more valuable than ever. What has changed is the accounting landscape, the dominant form of capital return, the role of intangibles on balance sheets, and the interest-rate environment that shaped Graham's discount-rate assumptions. You need the 1934 framework plus a 2026 adapter layer.
What parts of Graham's framework still work exactly as written?
Three parts are timeless. First, the margin of safety concept — the difference between intrinsic value and price — is a mathematical law, not a fashion. Second, the qualitative assessment of management (are they shareholder-friendly or do they loot the company through compensation and dilution?) is eternal. Third, Graham's psychological framework — the Mr. Market allegory, the distinction between investment and speculation, temperament as the primary determinant of returns — is if anything more relevant in a meme-stock era than it was in 1934.
What parts of Graham's framework need updating for 2026?
Four areas require modernization. First, accounting standards have shifted dramatically since the 1970s — GAAP, IFRS, non-GAAP 'adjusted' metrics, and the proliferation of stock-based compensation make Graham's raw earnings-power calculations incomplete. Second, intangible assets (brands, software, network effects) now dominate many balance sheets but Graham's book value analysis predates them. Third, capital returns have shifted from dividends to buybacks, which changes how you evaluate shareholder yield. Fourth, the zero-interest-rate era from 2009 to 2022 broke many of Graham's valuation benchmarks, which assumed risk-free rates in the 3-5% range.
Can Graham's framework be applied to preferred shares today?
Yes — and this is where Graham's work shines brightest in 2026. Graham devoted substantial chapters of Security Analysis to preferred share analysis because preferreds have defined par values, cumulative dividends, and contractual claims that let you calculate intrinsic value more precisely than common stocks. My live position in Fannie Mae and Freddie Mac junior preferreds (FNMA/FMCC) is almost a textbook Graham setup: $25-$50 par securities trading at a steep discount because of litigation uncertainty, with a clear contractual path to par if the conservatorship ends. Graham would have loved this trade.
Should I read Security Analysis or The Intelligent Investor first?
Read The Intelligent Investor first. It is the gateway — Graham's philosophy, psychology, and portfolio framework distilled into a readable book for general investors. Security Analysis is the graduate-level textbook that comes next. It is 766 pages of dense financial statement analysis, ratio definitions, and case studies. Most investors only need The Intelligent Investor. If you want to do real security-by-security analysis, you eventually need Security Analysis too.
Does Graham's net-net strategy still work in 2026?
In developed markets, almost never. Graham's net-net strategy — buying stocks below net current asset value, essentially paying less than the company's liquid working capital minus all liabilities — worked in the Depression era because markets were inefficient and small companies were largely ignored. Today, screens run by computers find these situations instantly, and what remains is usually junk (companies whose liquidation value is overstated by obsolete inventory or uncollectable receivables). The strategy still occasionally works in Japan, Korea, and emerging markets, but not reliably in the US.
How do buybacks change Graham's framework?
Graham analyzed companies as if their primary capital return mechanism was the dividend. In 2026, buybacks account for more capital return than dividends for most large US companies. Buybacks change the analysis in two ways. First, per-share metrics get distorted — a company that buys back 5% of shares annually will show per-share growth even with flat earnings. Second, buybacks at overvalued prices destroy value the way overpriced acquisitions do. A Graham-style analysis today requires calculating total shareholder yield (dividends plus buybacks net of dilution from stock-based compensation), not just the dividend yield.
How does the zero-rate era distort Graham's valuations?
Graham built his valuation benchmarks assuming risk-free rates around 3-5% and corporate bond rates around 5-8%. From 2009 to 2022, the 10-year Treasury traded between 0.5% and 3%, which inflated every discount-rate-sensitive valuation — growth stocks, long-duration bonds, and any asset valued on future cash flows. A P/E of 25 that looks insane by Graham's 1974 standards can be mathematically fair when the alternative is 1% risk-free. As rates have normalized in 2023-2026, many of those valuations have compressed — which is exactly what Graham would have predicted.
How do I value a stock the way Graham would today?
Start with earnings power, not reported earnings — strip out non-recurring items, adjust for stock-based compensation as a real cost, and look at the average earnings across a full cycle (5-10 years). Apply a conservative multiple based on growth and quality. Calculate tangible book value and compare it to market cap. Compute total shareholder yield. Check the balance sheet for hidden leverage (operating leases, pension underfunding, contingent liabilities). Demand a margin of safety of at least 30-50% between your estimate of intrinsic value and the price. Read the last five annual reports to assess management quality. That is Graham, modernized.
Why does Glen apply Graham to GSE preferreds instead of common stocks?
Two reasons. First, preferreds fit Graham's framework better than common stocks because they have defined terminal values (par) and contractual dividend claims — the calculation of intrinsic value is more precise. Second, the Fannie Mae and Freddie Mac situation is one of the rare cases in modern markets where a security trades at a deep discount to its contractual claim for reasons Graham would have recognized instantly: political and legal uncertainty, not business impairment. The underlying companies are massively profitable. The preferreds trade at 20-50% of par. That gap is the margin of safety, which is the central concept of Graham's entire life's work.
