1959 Letter to Limited Partners

The 1959 letter captures Buffett's apprehension about rising market levels and speculative behavior in "blue chip" stocks. It also details the progression of the Sanborn Map Co. investment, which grew to 35% of the partnership's assets.

📊 Performance Summary

  • Dow-Jones Industrials: +19.9% (including dividends).
  • Buffett Partnerships (6): Averaged ~25.9% (range: 22.3% to 30.0%).
  • Market Context: Buffett notes that while the indices were "robust," more stocks declined than advanced on the NYSE. He identifies a "substantial speculative component" in current prices.

🧐 The "New Era" Philosophy

Buffett explicitly rejects the then-current "New Era" philosophy (where "trees grow to the sky"). He states he would rather sustain the penalties of "over-conservatism" than face the permanent capital loss resulting from a speculative collapse. This reinforces his commitment to Intrinsic Value over market sentiment.

💎 Major Holding: Sanborn Map Co.

  • Concentration: This single investment grew to account for 35% of total partnership assets.
  • Nature: Buffett describes it as "partially an investment trust," owing to its large portfolio of marketable securities held alongside its map business.
  • Status: Buffett joined the Board and noted that the investment was carried at a "substantial discount" from asset value. He expressed hope for a successful conclusion in 1960.

🎯 Strategic Evolution

  • Relative Performance: Buffett reinforces the "Suggested Standard of Performance": outperforming in declining or level markets, even if results are unimpressive in rapidly rising markets.

🏢 Key Entities & Holdings

  • Sanborn Map Co.: The dominant position.
  • Tri-Continental Corp.: Mentioned as a comparison (+5.7%).
  • Massachusetts Investors Trust: Mentioned as a comparison (+9%).

🧐 1959 Shareholder Letter: "The Conservative's Manifesto"

"I would rather sustain the penalties of over-conservatism than face the consequences of error, perhaps with permanent capital loss, resulting from the adoption of a 'New Era' philosophy." — Warren Buffett, 1959

🎭 The Narrative Context

By 1959, the post-war bull market was entering its second decade and a dangerous consensus was forming: stocks could only go up. Market commentators spoke of a "New Era" where traditional valuation metrics were obsolete. Buffett, at 28, saw exactly what Benjamin Graham had described in Security Analysis: the intellectual capitulation that precedes a market reckoning. His response was not to sell everything and hide — it was to concentrate more heavily into a single, deeply undervalued situation (Sanborn Map, at 35% of assets) while publicly rejecting the prevailing orthodoxy. The juxtaposition is extraordinary: maximum concentration in a specific undervalued asset combined with maximum skepticism about the general market. This is not contradiction — it is the essence of value investing.

💡 Philosophical Gems

The Philosophy: Rejecting the "New Era"

The Premise: Buffett identifies a "substantial speculative component" in current stock prices, noting that more NYSE stocks declined than advanced despite the indices posting robust gains. The Logic: When index-level performance masks deteriorating breadth, the market is being driven by a narrowing group of overpriced favorites — the classic "generals marching while the troops retreat" pattern. The Conclusion: He would rather accept the performance penalty of being too conservative than risk permanent capital loss by participating in a speculative mania. This is Margin of Safety applied not just to individual securities but to portfolio-level asset allocation. The Pattern: The same logic reappears verbatim in 1969 (partnership dissolution), 1999 (dot-com refusal), and 2007 (cash hoarding). The sentence has never changed because the principle has never changed.

The Strategy: Extreme Concentration in Sanborn Map

The Position: Sanborn Map Co. grew to 35% of total partnership assets — an extraordinary concentration by any standard. The Thesis: Sanborn was "partially an investment trust" — a map company sitting on top of a large portfolio of marketable securities worth substantially more than the stock price. The operating business was mediocre, but the securities portfolio was excellent and completely unrecognized by the market. The Action: Buffett joined the Board, transforming this from a passive "General" into an active "Control" situation. He was no longer waiting for the market — he was engineering the outcome. The Insight: This 35% position is the earliest evidence of what became Portfolio Concentration as a deliberate strategy. Graham preached diversification; Buffett was already departing from his mentor's orthodoxy when the odds were overwhelmingly in his favor.

The Standard: Relative Performance as the Only Honest Metric

The Rule: Buffett reinforces that the partnership should be judged on relative performance — how it does versus the Dow — not on absolute returns. The Logic: In a year when the Dow gains 20%, a partnership gain of 10% is a failure. In a year when the Dow loses 20%, a partnership loss of 5% is a triumph. This framework strips away the emotional noise of big or small numbers and focuses purely on whether the manager is adding value. The Discipline: By establishing this standard during a bull market (when absolute returns look great), Buffett is pre-committing to accountability during the inevitable bear market.

🗣️ Verbatim Masterclass

  • "I would rather sustain the penalties of over-conservatism than face the consequences of error, perhaps with permanent capital loss, resulting from the adoption of a 'New Era' philosophy."
  • "The most important quality for an investor is temperament, not intellect."
  • "We do not intend to stake our reputation on our ability to predict what the market will do."

[!TIP] The 1959 letter delivers the single most important sentence in the partnership letters: "I would rather sustain the penalties of over-conservatism than face the consequences of error." This is not a platitude — it is an operational rule that Buffett followed literally for 67 years. It explains why he sat out the Nifty Fifty, the dot-com bubble, the crypto boom, and every other speculative mania. The penalty for conservatism is always visible and always temporary. The penalty for speculation can be permanent.
