2023年致股东信 | Buffett Letters 2023

1 Buy Wonderful Businesses at Fair Prices, Not Fair Businesses at Wonderful Prices ▼

English: Buy Wonderful Businesses at Fair Prices, Not Fair Businesses at Wonderful Prices

• 背景：: Charlie Munger's 1965 advice to Buffett after the Berkshire purchase. Munger told Buffett to abandon Ben Graham's approach of buying cheap mediocre businesses. • 核心教训：: The quality of the business matters more than the price you pay. A wonderful business purchased at a fair price will compound value over decades, while a mediocre business bought cheaply will eventually revert to mediocre economics. This insight transformed Berkshire from a struggling textile mill into a conglomerate of exceptional businesses. • 实践应用：: When making acquisitions or investments, prioritize business quality (durable competitive advantages, strong economics) over bargain pricing. A slight overpay for excellence beats a steal on mediocrity.

2 The Power of Patience and Inaction with Great Businesses ▼

English: The Power of Patience and Inaction with Great Businesses

• 背景：: Berkshire's decades-long holdings of Coca-Cola and American Express. They did not buy or sell a single share of either in 2023, extending a "Rip Van Winkle slumber" of over two decades. • 核心教训：: When you find a truly wonderful business, the optimal strategy is often to do absolutely nothing. Both Coke and AMEX rewarded Berkshire's inaction by increasing earnings and dividends year after year. Berkshire's share of AMEX earnings in 2023 considerably exceeded the entire $1.3 billion original purchase cost. • 实践应用：: Resist the urge to trade, tinker, or "upgrade" holdings that are performing well. One wonderful business held for decades can offset many mediocre decisions. Transaction costs and taxes from frequent trading destroy value.

3 Products That "Travel" Create Enduring Competitive Advantages ▼

English: Products That "Travel" Create Enduring Competitive Advantages

• 背景：: Discussing why Coca-Cola (founded 1886) and American Express (founded 1850) have endured for over a century. • 核心教训：: Both companies succeeded because their products "traveled" -- they became recognizable names worldwide. Moreover, their core offerings address timeless human needs: the consumption of liquids and the need for unquestioned financial trust. Businesses built on enduring human needs with global brand recognition have the strongest moats. • 实践应用：: Evaluate whether a business serves a timeless need and whether its brand/product can scale across geographies. Businesses tied to fundamental, unchanging human behaviors have the greatest durability.

4 Stick to Your Core -- Diversification into Unrelated Areas Usually Fails ▼

English: Stick to Your Core -- Diversification into Unrelated Areas Usually Fails

• 背景：: Both Coca-Cola and American Express tried expanding into unrelated areas over the years and found little success in these attempts. • 核心教训：: Even great companies stumble when they venture far from their core competency. The most successful path is to reshape and evolve the core business as conditions demand, rather than chasing unrelated opportunities. Strength comes from depth, not breadth. • 实践应用：: Before pursuing diversification, honestly assess whether the new area leverages existing competitive advantages. Unrelated diversification often destroys value, even for well-managed companies.

5 Never Risk Permanent Loss of Capital ▼

English: Never Risk Permanent Loss of Capital

• 背景：: Buffett's description of Berkshire's "not-so-secret weapon" -- its ability to respond to market panics with huge sums and certainty of performance. • 核心教训：: The single most important investment rule is to never risk permanent loss of capital. Thanks to the American economic tailwind and compound interest, you only need a couple of good decisions in a lifetime and must avoid serious mistakes. Survival is the prerequisite for compounding. • 实践应用：: Structure your business or portfolio so that no single event -- however catastrophic -- can wipe you out. Extreme fiscal conservatism may seem unnecessary in most years, but it is the insurance policy that allows you to survive and exploit crises others cannot.

6 Extreme Fiscal Conservatism as a Strategic Weapon ▼

English: Extreme Fiscal Conservatism as a Strategic Weapon

• 背景：: Berkshire's massive cash and Treasury bill position, zero reliance on commercial paper or bank lines during the 2008 panic, and its ability to generate cash from operations during crises. • 核心教训：: Holding far more cash than "conventional wisdom" deems necessary is not waste -- it is a strategic weapon. During the 2008 panic, Berkshire was a buyer while others were forced sellers. The company did not predict when paralysis would occur but was always prepared for one. This liquidity transforms crises from threats into opportunities. • 实践应用：: Maintain larger cash reserves than peers consider necessary. When competitors are scrambling for survival during downturns, your liquidity becomes your greatest competitive advantage -- allowing you to acquire assets cheaply and operate from a position of strength.

7 Beware Capital-Intensive Industries Where Maintenance CapEx Exceeds Depreciation ▼

English: Beware Capital-Intensive Industries Where Maintenance CapEx Exceeds Depreciation

• 背景：: BNSF railroad, which must spend more than its depreciation charge annually just to maintain current business levels. Outlays in excess of GAAP depreciation totaled $22 billion over 14 years. • 核心教训：: In capital-intensive industries, reported earnings can be deeply misleading. When a business must consistently spend more than depreciation to maintain operations, actual owner earnings are far below reported earnings. EBITDA is particularly misleading in such contexts (Buffett bans it as a metric at Berkshire). This gap explains why BNSF could be purchased at a small fraction of replacement value. • 实践应用：: Always compare maintenance capital expenditures to depreciation charges. If CapEx consistently exceeds depreciation, the business is less profitable than it appears on paper. Favor asset-light businesses where possible.

8 Regulatory Risk Can Destroy Even the Most Stable Industries ▼

English: Regulatory Risk Can Destroy Even the Most Stable Industries

• 背景：: Berkshire Hathaway Energy's problems in states where the traditional regulated-utility model broke down, with some states raising the specter of zero profitability or bankruptcy (as happened to California's largest utility and threatened in Hawaii). • 核心教训：: The century-old pact between utilities and regulators -- fixed returns on equity in exchange for massive capital investment -- can be broken. When it is, what was considered the most stable industry in America becomes potentially uninvestable. Climate change, wildfire liability, and shifting political winds can transform a safe business into a death trap. • 实践应用：: Never assume regulatory frameworks are permanent, no matter how long they have been in place. Monitor the political and regulatory environment as carefully as you monitor competitive dynamics. A business that depends entirely on regulatory goodwill carries hidden existential risk.

9 Never Deal with a Rascal Under the Expectation You Can Prevent Him from Cheating You ▼

English: Never Deal with a Rascal Under the Expectation You Can Prevent Him from Cheating You

• 背景：: Buffett quoting Hugh McCulloch, the first Comptroller of the United States (1863), about management integrity. Buffett added that "sincerity and empathy can easily be faked." • 核心教训：: Management integrity is the hardest thing to assess but among the most important. People are not easy to read, and many who thought they could "manage" dishonest people have learned painful lessons. The best approach is to avoid untrustworthy people entirely rather than trying to create systems to contain them. • 实践应用：: Walk away from deals with people of questionable character, regardless of how attractive the economics appear. No contract or monitoring system can fully protect you from a dishonest partner or manager.

10 Insurance Underwriters Must Not Be Optimists ▼

English: Insurance Underwriters Must Not Be Optimists

• 背景：: Berkshire's property-casualty insurance operations, which grew nearly 5,000-fold from $17 million to $83 billion in volume over 57 years. • 核心教训：: In insurance, surprises are almost always negative, and they can arrive decades after policies expire. Underwriters can be any demographic, but they cannot be optimists at the office. Optimistic assumptions about loss rates lead to underpricing, which leads to catastrophic losses. Estimation mistakes can be huge, and when charlatans are involved, detection is slow and costly. • 实践应用：: In any business that involves risk assessment, cultivate a culture of conservative estimation. Optimism bias is the silent killer of insurance companies, banks, and any enterprise that prices risk. Build margins of safety into every estimate.

11 规模是收益的敌人 ▼

English: Size Is the Enemy of Returns

• 背景：: Berkshire's $561 billion GAAP net worth -- nearly 6% of the entire S&P 500 universe. Only a handful of companies can "move the needle" at Berkshire's scale. • 核心教训：: As a company grows, the universe of opportunities that can meaningfully improve returns shrinks dramatically. Doubling a huge base within five years is simply not possible. The days of "eye-popping performance" are behind Berkshire, not because of declining skill but because of increasing size. Building positions through open markets at scale is "like turning a battleship." • 实践应用：: Recognize that strategies which work at small scale may not work at large scale. As your business grows, you must either accept lower marginal returns or find entirely new categories of opportunity. Growth itself can become a competitive disadvantage.

12 Shareholder-Friendly Capital Allocation (Japanese Companies Model) ▼

English: Shareholder-Friendly Capital Allocation (Japanese Companies Model)

• 背景：: Berkshire's investments in five large Japanese trading companies (Itochu, Marubeni, Mitsubishi, Mitsui, Sumitomo), which follow superior shareholder-friendly policies compared to U.S. norms. • 核心教训：: The five Japanese companies demonstrate superior capital allocation: each reduced outstanding shares at attractive prices, management compensation was far less aggressive than U.S. norms, they paid only about one-third of earnings as dividends (retaining the rest for growth and buybacks), and they were reluctant to issue shares. This disciplined approach to capital allocation creates long-term value. • 实践应用：: The best companies return capital thoughtfully -- buying back shares only at attractive prices, retaining earnings for high-return reinvestment, keeping management compensation reasonable, and avoiding share issuance that dilutes existing owners. Capital allocation discipline is a hallmark of great management.

13 Share Repurchases Must Be Price-Dependent ▼

English: Share Repurchases Must Be Price-Dependent

• 背景：: Buffett's "usual caveat" when discussing how Berkshire's repurchases increased shareholders' indirect ownership of Coke and AMEX. • 核心教训：: All stock repurchases should be price-dependent. What is sensible at a discount to business value becomes stupid if done at a premium. Too many companies repurchase shares regardless of price, often at peaks, effectively destroying shareholder value while appearing to return capital. • 实践应用：: Never conduct share buybacks on autopilot. Repurchase shares only when they trade below intrinsic value. Buying back overpriced shares is worse than paying an overpriced dividend -- it transfers wealth from continuing shareholders to departing ones.

14 Currency Risk Can Be Hedged Naturally Through Debt ▼

English: Currency Risk Can Be Hedged Naturally Through Debt

• 背景：: Berkshire financed most of its Japanese stock positions with yen-denominated bonds, generating a $1.9 billion gain as the yen weakened. • 核心教训：: Rather than trying to forecast currency movements (which Buffett says neither he nor anyone he could hire can do reliably), you can hedge currency exposure naturally by denominating your debt in the same currency as your assets. This creates an automatic offset without requiring speculative currency bets. • 实践应用：: When investing internationally, consider natural hedges through local-currency borrowing rather than attempting to predict exchange rate movements. Match the currency of your liabilities to the currency of your assets.

15 Build Your Business to Be an Asset in a Crisis, Not a Casualty ▼

English: Build Your Business to Be an Asset in a Crisis, Not a Casualty

• 背景：: Buffett's statement that during economic upsets, Berkshire's goal is to function as an asset to the country -- to help extinguish the financial fire rather than be among those who ignited it. • 核心教训：: The strongest businesses are those structured to thrive during adversity while competitors struggle. Berkshire's "Niagara of diverse earnings," minimal cash requirements, no material annual debt maturities, discretionary dividends, and massive liquidity all serve this purpose. Being the entity others turn to in a crisis is the ultimate competitive position. • 实践应用：: Structure your business so that downturns become your advantage. Diverse revenue streams, low fixed obligations, and ample reserves allow you to be a buyer when everyone else is a forced seller. The businesses that survive crises often emerge stronger than before.

16 Reported Earnings Can Be Worse Than Useless ▼

English: Reported Earnings Can Be Worse Than Useless

• 背景：: Berkshire's GAAP "net earnings" swung from $90 billion (2021) to negative $23 billion (2022) to $96 billion (2023) due to mandatory inclusion of unrealized capital gains and losses. • 核心教训：: Official accounting earnings, despite being sanctified by FASB, SEC, and auditors, can be "worse than useless" for evaluating a business. At Berkshire, unrealized capital gains can exceed $5 billion in a single day. Operating earnings ($27.6B, $30.9B, $37.4B for those same years) tell a far more coherent story. Investors who rely solely on mandated bottom-line figures are being misled. • 实践应用：: Always look beyond reported GAAP earnings to understand the true economic performance of a business. Develop your own framework for measuring operating performance that strips out non-cash, non-operational noise.

17 The American Tailwind Is Real -- But You Must Sit Quietly ▼

English: The American Tailwind Is Real -- But You Must Sit Quietly

• 背景：: Buffett's first stock purchase on March 11, 1942, when the Dow was below 100. By 2023, it hovered around 38,000. • 核心教训：: America has been a terrific country for investors. The primary requirement for capturing this wealth creation has been to invest in U.S. equities and sit quietly, listening to no one. The investors who failed were not those who picked bad starting points, but those who couldn't resist the urge to react to noise, pundits, and market gyrations. • 实践应用：: For long-term investors, the biggest risk is not market volatility but behavioral -- the temptation to act on short-term noise. The simplest and most powerful strategy is to own good businesses and resist the urge to trade.

18 Wall Street's Incentives Are Misaligned with Yours ▼

English: Wall Street's Incentives Are Misaligned with Yours

• 背景：: Buffett's observation about Wall Street's casino-like behavior and the financial industry's true incentive structure. • 核心教训：: Wall Street would like its customers to make money, but what truly drives its revenue is feverish activity. Whatever foolishness can be marketed will be vigorously marketed -- not by everyone, but always by someone. Markets now exhibit far more casino-like behavior than in previous decades, with the "casino" now residing in many homes via technology. • 实践应用：: Recognize that most financial industry participants profit from your activity, not your returns. Every time someone encourages you to trade, switch strategies, or chase a trend, ask whose interests are truly being served. The quieter your portfolio, the more Wall Street loses and you gain.

19 Acknowledge Mistakes Openly and Learn from Them ▼

English: Acknowledge Mistakes Openly and Learn from Them

• 背景：: Buffett's candid admission that he made a "costly mistake" by not anticipating adverse regulatory developments at BHE, and that he erred in his earnings expectations for both BNSF and BHE. • 核心教训：: Even after 59 years of assembling Berkshire, Buffett openly acknowledges errors in judgment. He promised shareholders honest reporting of both good and bad news, delivered directly from the CEO -- not filtered through investor-relations officers serving up "optimism and syrupy mush." This transparency builds the trust that attracts long-term shareholders. • 实践应用：: Build a culture where mistakes are acknowledged quickly and openly. Leaders who admit errors earn more trust than those who hide them. Honest communication with stakeholders -- even when the news is bad -- is a competitive advantage in attracting long-term partners and investors.

20 Essential but Capital-Hungry Infrastructure Has Unique Economics ▼

English: Essential but Capital-Hungry Infrastructure Has Unique Economics

• 背景：: BNSF railroad -- essential to America's economy, carrying freight over 23,759 miles of track, with assets that would cost at least $500 billion to replicate. • 核心教训：: Some businesses are essential to the economy (railroads, utilities, pipelines) but have challenging economics for owners: they consume enormous capital, face regulatory constraints, carry common-carrier obligations, and must operate in harsh conditions. Their replacement value far exceeds book value, but actual returns to owners are modest relative to the capital employed. Being irreplaceable does not mean being highly profitable. • 实践应用：: Distinguish between a business being essential and being a good investment. Infrastructure businesses may be irreplaceable but still deliver mediocre returns due to capital intensity, regulatory burdens, and operational challenges. Price your entry accordingly.
