Robotti & Company is a New York deep-value boutique founded by Bob Robotti in 1983, specializing in left-for-dead cyclical industries — energy services, building products, shipping — with multi-year holding periods and occasional activist letters. It manages about $650m; Bob is regarded as one of the most steadfast Graham-tradition cyclical value hunters.

This letter explains how to profit from buying cheap stocks that the market has abandoned. The key example is Builders FirstSource (BLDR), a construction company. In 2014, its stock price dropped sharply even though the business was fine. The author bought more shares, and later BLDR bought a big competitor, nearly doubling the stock price. For ordinary investors, the lesson is to stay patient and not panic over short-term bad news. If the company is solid, its price will eventually reflect its true value. Worth reading for a real-world case of contrarian investing and long-term holding.
Robotti's research report discusses a strategy for achieving long-term excess returns by investing in low-priced stocks. The core argument is that bad news is typically already priced into cheap stocks, and investors should control their emotions and focus on business fundamentals rather than waitin
This chapter is a quarterly letter from Robotti & Company to its partners, focusing on a strategy of achieving long-term excess returns by investing in low-priced stocks. The author uses Builders FirstSource (BLDR) as an example to illustrate the investment logic of buying during an industry downturn and patiently holding until industry consolidation materializes. The market backdrop is the deep depression in the U.S. housing market after 2008, yet a structural demand gap persists.

3. Comparison Data Table:
| Metric | Q3 2014 Forecast (Pre-Merger) | Post-Merger New Forecast (2015) |
|---|---|---|
| Normalized Revenue | $2.5 billion | $10 billion |
| Normalized EBITDA | $150 million | $800 million |
| Shares Outstanding | 100 million | 110 million |
| EBITDA per Share | $1.50 | $7.27 |
The continuation uses the stock price volatility of Builders FirstSource (BLDR) as a starting point to show how market sentiment causes short-term disconnects between price and value. From April to September 2014, BLDR's stock price plunged 45% from its 52-week high of $9.40 to $5.104, yet the company's fundamentals did not deteriorate — in fact, it added $43 million in revenue through three acquisitions, and net debt only increased slightly from $290 million to $319 million. Enterprise value (EV) plummeted from $1.2 billion to $830 million, a decline of 31%, while both revenue and earnings improved over the same period.
Key Data Comparison:
| Metric | April 4, 2014 | September 29, 2014 | Change |
|---|---|---|---|
| Diluted Shares Outstanding | 97.6 million | 100.8 million | +3.3% |
| Net Debt | $290 million | $319 million | +10% |
| Enterprise Value (EV) | $1.2 billion | $830 million | -31% |
| Revenue (TTM) | ~$1.55 billion | ~$1.6 billion (incl. acquisitions) | +3.2% |
| EBITDA Margin | 4.1% | 4.4% | +30bp |
Conclusion: The market discounted the same company by 31% in six months, while fundamentals did not deteriorate. This confirms Graham's assertion: short-term price fluctuations are the emotional outbursts of "Mr. Market," not a true reflection of intrinsic business value.
The continuation points out that when forecasters reach a consensus, that outcome is often the least likely to occur. In 2012-2013, the market consensus was that U.S. real estate had entered a "rebound mode," but after new home starts declined in early 2014, the consensus quickly reversed. This "all-or-nothing" mindset is a classic manifestation of the "anchoring effect" and "herd behavior" in behavioral finance.
Historical Data Support:
Insight: When the market is uniformly bearish, it often means pessimistic expectations are fully priced in, and contrarian investing at that point can yield excess returns. BLDR's low point in September 2014 was a value trough following extreme market pessimism.
The continuation uses long-term data to argue that current single-family home starts (643,000 units) are far below the post-1970 average (1.05 million units/year), and the U.S. population has grown 56% (1970-2014), with the number of households increasing 46% (1980-2010). This means that even without considering a cyclical rebound, mere mean reversion could drive at least a 60% increase in starts.
Key Assumptions and Calculations:
Industry Consolidation Dividend: The top five companies in the building distribution industry (ProBuild, 84 Lumber, BLDR, BMC, Stock Building Supply) hold only a 25% market share. Long-term consolidation will drive revenue growth beyond the industry cycle. BLDR's revenue per start increased from $1,534 in 2009 to $2,399 in 2013, a CAGR of 11.8%, with consolidation effects already evident.
The continuation introduces the concept of "time arbitrage" — when most investors focus on 3-6 month short-term fluctuations, long-term investors with a 3-5 year horizon can gain a significant advantage. The BLDR case is a practical application of this strategy: the market sells off due to short-term pessimism, while long-term investors buy based on mean reversion and industry consolidation logic.
Historical Case Support:
Core Logic: Short-term uncertainties (e.g., interest rate policy, quarterly earnings) are unpredictable, but long-term structural trends (e.g., population growth, industry consolidation) can be grasped. When the price is below intrinsic value, the margin of safety is wide enough to invest without precise valuation.
The continuation emphasizes that the BLDR investment opportunity was not based on precise valuation, but on the vague judgment that "the gap between price and value is large enough." In September 2014, BLDR's EV/EBITDA was only about 5x (based on TTM EBITDA), while comparable distribution companies (e.g., Fastenal, W.W. Grainger) typically trade at 10-15x. Even under conservative assumptions, BLDR's intrinsic value was far above its $830 million EV.
Quantified Margin of Safety:
Conclusion: When the gap between price and value is vast, investors do not need to calculate intrinsic value precisely. As Graham said: "Price is what you pay; value is what you get." The BLDR case proves that when market sentiment causes a significant price deviation, long-term investors should use "time arbitrage" to capture excess returns.
