Berkshire Hathaway 2008 Annual Letter

The bottom line: Written at the peak of the worst financial crisis since the Great Depression, this letter is a masterclass in how to think during a panic — and why financial strength held in reserve is worth more than any individual investment.

The best opportunities come when everyone else is selling

• Berkshire deployed $14.5 billion during the crisis at highly favorable terms — the kind only available when you have cash and everyone else needs it
• This was only possible because Berkshire had no liquidity pressure — no margin calls, no forced selling

Owning mistakes publicly creates better decision-making privately

• Buffett named his errors explicitly — ConocoPhillips, two Irish banks — with specific dollar amounts
• Publicly committing to honesty about mistakes forces you to actually examine what went wrong
• Most investors bury losses mentally and move on without extracting the lesson — guaranteeing the mistake gets repeated

Derivatives are risks you cannot see until it is too late

• If you cannot understand what is on a company's balance sheet, do not invest in it — complexity that cannot be explained is risk that cannot be measured
• Berkshire held derivatives but required counterparties to pay upfront — meaning Berkshire already held the cash and had nothing to lose if the other party went bankrupt

Panic is the wrong response to falling prices

• Short-term price declines in fundamentally sound businesses are not losses — they are opportunities priced as if they were losses
• The investors who did best after 2008 held or added to quality positions during the panic
• Most investors sell when prices drop out of fear — that collective behavior pushes prices below what a business is actually worth, which is what creates the buying opportunity in the first place

Berkshire Hathaway 2013 Annual Letter

The bottom line: Using a farm and a commercial property, Buffett strips away all the noise around markets and macro forecasts and returns investing to its most essential question — what will this asset produce over time? Every investor should read this before making their next decision.

You do not need to predict the economy to invest well

• Buffett made no forecast about interest rates or GDP — he only asked what the asset would produce over time
• Most investors spend enormous energy on predictions that are unknowable and ignore the analysis that actually matters
• The question is never "where is the market going?" — it is "what will this business earn over the next 10 years?"

Doing nothing is often the highest-return decision

• Coca-Cola purchased for $1.3 billion in 1994 was worth $25 billion by 2013 — the only action required was holding
• Every time you sell a great business to buy something slightly better, you pay taxes, reset your cost basis, and interrupt compounding
• The investors who make the fewest transactions over the longest periods tend to produce the best results

Low-cost index funds beat most professional managers

• The "know-nothing" investor who diversifies broadly and keeps costs minimal will outperform most sophisticated strategies
• This is backed by decades of data that the investment management industry has strong financial incentives to obscure
• For most people, a low-cost S&P 500 index fund is the single best investment decision they can make

The right manager matters as much as the right business

• A great business with a mediocre manager is a diminishing asset
• Before investing in any company, spend as much time evaluating management behavior as reading financial statements
• The best managers make decisions as if their own family's savings were entirely tied up in the business — which tends to produce more careful, long-term thinking than a manager who is simply collecting a salary
