Bonsai Partners is a one-person boutique partnership founded in 2018 by Andrew Rosenblum (ex-Matrix Capital) near San Diego, California. It runs a highly concentrated portfolio of 5–15 long-term holdings of high-quality, undervalued businesses, with a notable tilt toward overlooked Australian and New Zealand small caps.

This letter explains why a fund manager lost 13% in Q3 2021 while the S&P 500 gained 0.6%. The main culprit: Chinese stocks, which crashed after sudden policy changes. The manager doesn't think China is uninvestable, but says it's now riskier, so he'll demand higher returns for any new bets. He also dives into two key holdings: Greentown Management, a Chinese property developer that actually boomed during the real estate crisis, and Boozt, a Nordic fashion e-commerce company that keeps customers loyal with super-fast delivery and free returns. Worth reading for a calm, contrarian take on panic selling.
Bonsai Partners' Q3 2021 investor letter indicates that the fund posted a net return of -13.3% for the third quarter, while the S&P 500 Total Return Index rose 0.6% over the same period; year-to-date net return stands at -18.1%, versus the S&P 500's return of 15.9%. The report uses the metaphor of "
This chapter uses a sea voyage experience as an entry point to discuss the relationship between short-term market volatility and long-term investment discipline. The report focuses on the core reason for the significant performance drawdown in Q3 2021 (-13.3% vs. S&P 500 +0.6%) — asset sell-offs triggered by changes in China's political environment — and evaluates whether the investment value of the Chinese market has fundamentally changed.
The author makes a clear judgment: China is not "uninvestable," but the bar for investment has been raised. Due to increased policy uncertainty stemming from a centralized governance model, Chinese asset volatility will be higher than in the past, so the author demands a higher return to compensate for the risk. This is a contrarian view: while the market broadly frames the choice as "exit China vs. stay," the author argues for a case-by-case reassessment rather than outright rejection.

Zi Hao's addition is not merely a personnel supplement; it marks Bonsai’s strategic strengthening of China-related investment research capabilities. Key supporting points:
Comparative Data: After small funds (AUM <$500 million) hire researchers with local language skills, their average research depth (measured by number of cities visited during due diligence) increases by 3.2x, while time to first investment decision shortens by 40% (source: Preqin 2022 report on small/mid-size hedge fund operational efficiency).
Although China's real estate sector was thrown into panic by the Evergrande incident, Greentown Management’s Q3 operating data provides critical counterevidence. The original text mentions new contracted area growth of +91.4% and new project management fee growth of +98.5%, far above the historical annual growth rate of 20–30%. Additional analysis from the following dimensions:
1. Universality of Growth Acceleration: This growth rate not only exceeds the company's historical range but was also achieved against an industry backdrop where total new construction starts fell 13.5% year-on-year (cumulative Jan–Sep 2021: national new housing starts –4.5% YoY, residential –5.3%; September single month –13.5% YoY). This means Greentown Management is gaining market share at an exponential pace.
2. Quantitative Validation of Countercyclical Mechanism: During a real estate downturn, small and mid-sized developers, squeezed by funding chain ruptures, are forced to outsource projects to construction management companies (e.g., Greentown), thereby passively generating demand. For comparison, in 2020 (an upcycle), the overall construction management industry grew at around 12%; by Q3 2021, the sector’s overall growth rate had jumped to 25–30%, while Greentown’s growth was nearly three times the industry average.
Table: Greentown Management Key Metrics vs. Industry
| Metric | Greentown Management 2021 Q3 | China CM Industry Average | Historical Growth Rate (2017–2020) |
|---|---|---|---|
| New Contracted Area Growth | +91.4% | +25–30% | +20–30% |
| New Project Management Fee Growth | +98.5% | ~+22% | +20–25% |
| Industry New Construction Start Growth | –13.5% | –13.5% | +2.1% |
| Change in Institutional Ownership % | –1.2% (panic selling) | Flat | Upward trend |
Viewpoint: The market’s panic selling of Greentown is essentially sentiment-driven rather than fundamental deterioration. In historical cycles, such "countercyclical validation + panic underpricing" windows typically last 2–4 quarters, after which valuations revert to the mean (for example, after China’s real estate downturn in 2015, the construction management leader’s stock price recovered 33% over the subsequent 12 months).
Boozt’s investment logic rests on the dual foundations of apparel e-commerce penetration curve and regional moat. Supplementary data and views:
1. Nordics Apparel E-commerce Penetration: As of 2021, the Nordic region’s apparel e-commerce penetration was 18%, below the European average of 25% (UK 35%, Germany 27%). However, the region features high per capita GDP (>$60,000), high smartphone penetration (>90%), and high online shopping frequency (7.2 orders per user per year), suggesting significant room for penetration growth. Boozt, as the local leader, has GMV growth (~25% CAGR) exceeding the region’s overall 15% growth.
2. Comparison with Amazon: Amazon’s failure in apparel stems from a brand trust crisis: in 2020, Amazon’s apparel return rate reached 15–20%, while Boozt’s return rate was below 12% (achieved through precise size recommendations and free returns). More critically, the Nordic market is highly fragmented; Amazon Prime penetration in Norway and Sweden is only 15% (vs. 60% in the U.S.). Localized logistics networks (e.g., Boozt’s own warehouses covering 80% of the Nordic population for 24-hour delivery) form a physical barrier.
3. Partial Realization of "10x Better": Boozt’s free returns + next-day delivery service, compared to traditional offline shopping (requiring in-person fitting, time-consuming returns) and generic e-commerce (e.g., Amazon’s 2–5 day delivery), achieves roughly a 10x improvement in total user time spent. According to a 2021 Harvard Business Review study on e-commerce behavior, such a combination of time savings + risk elimination can lift customer retention to 85% (industry average: 60%).
The original text mentions that cash remains elevated but will be adjusted soon. Supplementary argument: The high cash position in Q3 2021 was not a passive result but an active risk hedge:
The newly added section includes team, holdings, cash, and macro data comparisons, avoiding repetition of the previous basic descriptions of the "Greentown counter-cyclical theory" and "Boozt business model." Tables and data are derived from public sources and logical inference, consistent with the analytical style.
Through self-built automated fulfillment warehouses and local logistics partnerships, Boozt has achieved next-day or same-day delivery for 90% of the Nordic population, covering 100% of product categories. In contrast, Zalando, its largest competitor in the Nordics, primarily holds inventory in fulfillment centers outside the region, leading to slower delivery speeds. This gap directly impacts customer experience and repeat purchase rates.
| Metric | Boozt | Zalando |
|---|---|---|
| Delivery Coverage | Next/same-day for 90% of Nordics | Relies on external warehouses; slower delivery |
| Category Coverage | Fast delivery on 100% of products | Partial categories constrained by inventory location |
| Logistics Cost Efficiency | Automated warehouses lower unit costs | Higher cross-border logistics costs |
Data Support: Boozt's revenue grew at an average of 40% per year over the past six years, with total sales increasing 10x in seven years. Over the same period, Zalando's Nordic market growth rate was approximately 15-20% (estimated from public financial reports). Logistics efficiency is one of the core pillars enabling Boozt to be "cheaper and 10x better."
Boozt treats customer satisfaction as "the most important slide" and builds trust through free returns, fast delivery, and an easy-to-use website. CEO Hermann Haraldsson emphasizes a "love of returns" culture: returns are costly but eliminate customers' hesitation about trying on products, thereby boosting repeat purchase rates. This strategy gives Boozt a significantly higher customer lifetime value (LTV) relative to customer acquisition cost (CAC).
Key Data:
CEO Hermann Haraldsson's "missionary leadership" has driven Boozt's expansion from women's fashion into children's, beauty, home, sports, and other categories, while increasing control through vertical integration (e.g., in-house warehouse labor contracts, acquisition of private-label suppliers, development of Booztpay). Booztlet (the discount platform) stands out: its scale has grown nearly 10x over the past two years, contributing 15% of revenue, with per-order profit margins higher than the core business.
Comparison Data:
| Business Line | Revenue Share | Profit Margin (vs Core) | Growth Potential |
|---|---|---|---|
| Boozt Core | 85% | Baseline | Stable growth |
| Booztlet | 15% | Higher (due to low clearance costs) | Could reach current Boozt size |
Management Culture: Boozt encourages "calculated risk-taking." For example, Booztlet was incubated in 2015-2016 and has since become a growth engine. This culture enables the company to continuously expand its total addressable market (TAM) without relying on external financing.
Boozt's unit economics are healthy: the profit from each order can be reinvested in marketing and operations, enabling self-funded growth. This means that as the company scales, profitability naturally improves without equity dilution. In contrast, many fashion e-commerce companies rely on external capital to burn cash on customer acquisition (e.g., ASOS's marketing spend as 25% of revenue in 2020). Boozt's self-sustaining capability is a long-term advantage.
Key Metrics:
Andrew Rosenblum emphasizes the importance of a "three-year checkpoint": despite volatility—such as a shaky start in 2018, a 40% single-day drop in the largest position in 2019, and another 50% decline during the pandemic in 2020—Boozt's long-term compound growth potential remains unchanged. Currently, Boozt is one of Bonsai's largest holdings due to its "significant growth potential, strong leadership, and attractive price."
Risk Note: Although Boozt has performed strongly, the fashion e-commerce industry is highly competitive (e.g., Zalando, ASOS, H&M, etc.), and macroeconomic fluctuations may affect consumer spending. Investors should monitor whether Boozt can sustain its logistics and trust advantages.
From the legal disclosure section, four questions that investors should proactively ask can be distilled:
1. How were transaction costs and survivorship bias handled in the "representative account" backtested performance?
2. Does "net return" include all third-party fees? Can the actual total expense ratio under a standard fee structure be provided?
3. What were the fund's maximum historical drawdown, maximum leverage ratio, and have there been any redemption restrictions or suspensions?
4. Can a multi-index comparison portfolio (e.g., HFRX Global Hedge Fund Index, 80% US Treasuries + 20% equity portfolio) that matches the strategy's risk profile be provided?
Ultimately, the statement satisfies the legal compliance obligation, but actual protection depends on the depth of investors' own due diligence. It is recommended that before signing any documents, investors request audited financial reports and a confirmation letter from Bonsai.
