Concrete step-by-step playbook for retail investors who want to apply Warren Buffett's documented framework today. From opening a brokerage account to making your first selection, with the exact metrics, thresholds, and timeframes to use.
Why stock prices fall without bad news: the 6 mechanical reasons that have nothing to do with the underlying business
A stock can drop 20 percent in a week with no fundamental change. Six structural reasons (sector rotation, index rebalancing, options flow, sentiment cascade, tax-loss harvesting, redemption pressure) that explain price moves the news doesn't.
Why the Magic Formula stopped working in 2024 (and what to do about it)
Joel Greenblatt's Magic Formula returned ~30% annualised in the 1988-2004 back-test. Over the rolling 5 years ending 2024 it underperformed the S&P 500 by ~6 percentage points. Here is why, and how the quality+value combination needs to evolve to keep beating the index in 2026.
Where Buffett would shop now: Q2 2026 edition — 10 stocks that pass every one of his published criteria
Quarterly contrarian column applying Warren Buffett's documented framework to the current US market. The 10 stocks that pass all five Buffett pillars and meet Berkshire's typical sizing constraints right now, with the financial case for each in 2-3 sentences.
"Invest like Warren Buffett" is a phrase that means everything and nothing. Buffett himself has spent six decades explaining his approach across shareholder letters, books, and interviews — but the published material is often more philosophical than practical. This post is the opposite: 12 concrete steps a retail investor can follow today, with specific thresholds and timeframes, to actually apply Buffett's framework.
Not "buy what you understand." Twelve actual steps you do in order.
The first practical step is the brokerage choice. Most "robo-advisor" apps make individual stock purchases either friction-heavy or impossible; you want a brokerage where buying one share of Coca-Cola in 2026 and holding it untouched until 2046 is a frictionless default.
Recommended brokerages:
Avoid platforms with payment-for-order-flow (PFOF) routing in jurisdictions where it's legal — your execution prices may be worse than the displayed quote.
Buffett has been clear: the worst time to be forced to sell stocks is during a crash, which is exactly when you need cash for an emergency. Before any stock investment, build an emergency fund of 3-6 months of expenses in a high-yield savings account, money market fund, or short-term Treasury bills.
This is not investment money. It is the psychological foundation that lets you NOT panic-sell in 2026's eventual drawdown.
Buffett's published answer is "forever, or as long as the business stays wonderful." If you can commit to a 10+ year minimum holding period, you're in the right framework. If you'd sell at a 30 percent gain, you're not actually applying Buffett's approach — you're momentum trading with value language. Be honest with yourself before going further.
Buffett himself has said multiple times that for the typical retail investor, "the best investment by far is a low-cost S&P 500 index fund." Before picking individual stocks, your default position should be a broad-market index fund:
Allocate 50-70 percent of your investing capital to this index position. The remaining 30-50 percent goes to individual stock picks if you have the time and discipline. If you don't, just 100 percent index and skip the rest of this post.
Buffett's whole framework rests on understanding a business. The only way to understand a business is to read its primary source — the annual report (10-K in the US, Geschäftsbericht in Germany, Annual Report in the UK).
Focus on these sections in order:
You don't need to understand every detail. You need to be able to answer: what does this company sell, how does it make money, what's the moat, and what's the worst-case scenario. The first 10-K takes 4-6 hours to read. The 10th takes 90 minutes.
Don't try to evaluate 50 stocks. Pick 3-5 candidates from a curated framework-aware list. Sources:
For each candidate, do a 1-hour first-pass read: the company's last 10-K, the most recent quarterly results, and the per-stock analysis on invest-like.com if it's covered.
The Munger discipline: a written checklist beats unaided judgement. The full checklist is at /blog/value-investing-checklist-printable-2026/. Twenty-seven questions across business quality, balance sheet, management, valuation, and personal fit. Answer them in writing for each candidate.
A candidate that fails 3 or more questions: move on. A candidate that passes most questions but fails on one specific point: that point is your bear case — be honest about whether you can live with it.
The Buffett valuation is a discounted cash flow (DCF) on owner earnings (free cash flow with a maintenance-capex adjustment). For each candidate that passed Step 7:
This gives you an intrinsic value range. Don't fixate on the exact number; focus on the range — if your conservative-case DCF says fair value is $80-100 and the current price is $60, there's clear margin of safety. If the range is $90-110 and current price is $105, walk away.
Tools to do this: invest-like.com's /buffett/[ticker]/ page surfaces the DCF for every stock, or you can build your own in Excel/Google Sheets from the 10-K cash flow statement.
Buffett's rule: don't buy at fair value. Buy at a 30+ percent discount to your conservative DCF estimate. The margin of safety is your protection against being wrong about the growth rate, the moat durability, or the macro environment.
In practice, this means waiting. Sometimes 6 months. Sometimes 2 years. Sometimes never, for some stocks. Buffett famously waited for IBM in 1979 (didn't buy), then 2011 (bought), then 2017 (sold). Patience is structural to the framework.
If a stock passes Steps 1-8 but the current price is too high, put it on a watchlist with your DCF estimate as the trigger price. Check quarterly.
When you do buy, size matters. Buffett-style portfolios are concentrated: 5-15 positions typically, with the highest-conviction names sized at 5-15 percent of the portfolio each. The Kelly criterion math suggests slightly larger sizing for higher-conviction positions, but most retail investors size too aggressively when excited and too conservatively when fearful. A simple rule: equal-weight your top 10-15 positions, with the index fund acting as the diversification base.
Do not concentrate more than 10 percent in a single stock until you've held it for 12+ months without a thesis-breaking event.
If you've decided to allocate 5 percent of your portfolio to Stock X, don't buy the full 5 percent in one Monday morning order. Buffett historically built positions over weeks or months as he waited for opportunistic prices.
Practical approach: split into 3 tranches over 60 days. Buy 1/3 immediately, 1/3 if the stock dips 5 percent, 1/3 if it dips another 5 percent. If the stock never dips, you've committed to 1/3 at your initial entry price, which is fine.
After buying, the actual work is to NOT trade. Re-read the quarterly earnings reports. Update your DCF every quarter with the new numbers. Track whether your original thesis is intact.
Sell criteria:
DO NOT sell because:
How much money do I need to start? Mathematically, $500. Practically, $5,000 to make brokerage friction acceptable. The compounding math works at any size; the size just affects how long until the dollar amounts feel meaningful.
Can I do this if I have a full-time job? Yes. The active research takes 4-8 hours per stock initially, then 1-2 hours per quarter to re-check. A 10-stock portfolio is 10-20 hours per quarter to maintain. Most working professionals can do that in evenings and weekends.
What if I make a mistake? You will. Every value investor including Buffett has documented mistakes — Buffett's letters list errors openly. The framework is robust to mistakes: a position size of 5-10 percent means a -50 percent permanent loss on one name costs you 2.5-5 percent of the portfolio. Survivable. Concentrated 25 percent positions in unproven theses are not.
Should I follow Berkshire's 13F? Worth tracking as a data point, not as a buy signal. Berkshire's 13F is published 45 days after quarter-end, so by the time you see it, the price has already moved. Track it for ideas, validate independently.
