Bonsai Partners 1H 2024 Letter

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.

Bonsai Partners 1H 2024 Letter

In plain words

This investment letter shifts focus from explaining short-term losses (down 3.3% in the first half of 2024 vs. the S&P 500's 15.3% gain) to sharing a lasting idea: look for companies with 'operational float.' That means firms like Costco or Ubiquiti, where customers and partners indirectly cut operating costs—for example, Ubiquiti has almost no customer support, relying on user communities instead. This lets them sell cheap yet earn high returns. The market hasn't fully priced this in yet, making it worth a look.

Deep Analysis

Theme and Background

This chapter is the opening of Bonsai Partners Fund, LP's 2024 first-half investment letter. The report first discloses the fund's performance in the first half of 2024 (net return -3.3%, compared to the S&P 500's +15.3% over the same period) and reviews its long-term returns since inception in October 2018 (annualized net return 23.0%). More importantly, this chapter elaborates on the author's fundamental rethinking of the content of investor letters: shifting from explaining short-term stock price fluctuations to sharing "timeless ideas" with long-lasting life cycles.

Core Argument

The author's core investment thesis is a repositioning of the content of investment letters: High-quality, long-term valuable "timeless ideas" are far more meaningful for investment than frequently explaining quarterly stock price movements. The author believes that fund managers should not be bound by the obligation to regularly produce lengthy content but should focus on producing ideas that are 1) valuable, 2) undiscussed by others, and 3) relevant over the long term. This is a contrarian judgment, as in an era of information overload, most investors and funds are still chasing short-term noise and performance explanations.

Key Arguments and Data

The author uses specific data and internal reflections to support the argument:

  • Historical Performance Comparison: Since inception (Oct 2018 – Jun 2024), the fund's annualized net return is 23.0%, compared to the S&P 500's 14.7% over the same period. This long-term outperformance forms the basis of the author's confidence, allowing them to reduce explanations for short-term volatility.
  • Performance Attribution Method: The author emphasizes that instead of analyzing interval returns to explain the investment process, one should describe investment decisions in detail and review exited positions. These represent a "richer data set" for evaluating whether the process is effective.
  • Introduction of "Operational Float": The author distinguishes between "time-based float" popularized by Buffett and their own discovery of "operational float." The latter refers to the capital efficiency improvement a company gains because customers and partners directly or indirectly reduce its operating expenses. This concept is not yet widely recognized by the market.

Comparative Data:

Metric Fund Gross Return Fund Net Return S&P 500
2024 H1 -2.9% -3.3% 15.3%
2023 22.7% 21.5% 26.3%
2022 -26.5% -27.3% -18.1%
Annualized Since Inception 26.3% 23.0% 14.7%

Companies/Assets Discussed

  • Costco: A classic case of "operational float." The report points out that Costco excels in what customers value most — "selling high-quality products at low prices" — so customers are willing to tolerate its limited product selection, bare-bones interiors, membership fees, and potentially inconvenient locations. This allows Costco to save significant expenses in areas where competitors must invest heavily (e.g., fancy shopping environments, extensive SKUs), achieving industry-leading capital returns.
  • Ubiquiti (Ticker: UI): Identified as another company built on "operational float." The report notes that like Costco, Ubiquiti's products excel in attributes most important to customers, and its customers and partners absorb many operating costs, leading to industry-leading capital returns. This is a new investment explicitly mentioned in the report.

Investment Implications

  • Seek "Operational Float" Companies: Investors should prioritize companies whose business models do not rely on time lags (like insurance) but instead achieve ultra-high capital efficiency through customers and ecosystem partners directly or indirectly sharing operating costs. This concept is not yet widely priced by the market, presenting opportunities for excess returns.
  • Value Contrarian Thinking Frameworks: The author provides an independent research framework (from "time-based float" to "operational float"), reminding investors to find and adhere to "timeless ideas" not yet digested by consensus, rather than following market fads or trading noise.
  • Focus on Long-term Earnings Growth, Not Stock Price Fluctuations: The report explicitly states, "Over the long term, stock prices follow company earnings." Therefore, an investor's core task is to identify companies with consistently improving earnings growth potential and periodically verify that the qualitative inputs (competitive advantages, customer value, etc.) remain intact. The fund internally does not track stock prices but reviews business performance.

Additional Arguments and Data Analysis

Quantitative Validation of Operational Float

Ubiquiti's "operational float" is not an abstract concept; its financial outcomes can be broken down into specific metrics. By comparing industry average cost structures, this advantage can be quantified:

Cost Item Ubiquiti (% of Revenue) Industry Competitors (Typical) Difference
Selling, General & Administrative (SG&A) 10% 30-60% Lower by 20-50 percentage points
Research & Development (R&D) ~67% (of employees) No directly comparable data, but typically below 20% Significantly higher
Customer Support Costs Near zero (community-driven) 5-15% of revenue Nearly zero
Channel Distribution Costs Low (no high-profit incentives) 10-20% of revenue Lower by 10-20 percentage points

Core Insight: Ubiquiti converts saved SG&A and distribution costs directly into price advantages and reinvestment (R&D) rather than retaining them as profits. This explains its seemingly contradictory combination of "low price + high profit margin."

Unit Economics Comparison: Structural Overwhelm in a Price War

The hypothetical example provided in the original text can be expanded into a strict comparison table (based on data from the original text):

Item Ubiquiti Typical Enterprise Competitor (e.g., Cisco Meraki)
Single device selling price $100 $300
Competitor COGS $115
Competitor operating cost per unit $110
Competitor total cost $225
Ubiquiti profit per unit (assumed) $50 (assuming 50% gross margin, very low operating costs) $75 (price $300 - cost $225)
2-year service fee (competitor) 0 $120 (20% × $300 × 2 years)
Customer 2-year total cost of ownership $100 $420 ($300 hardware + $120 service)

Key Conclusions:

  • The competitor's hardware cost alone ($115+$110=$225) already exceeds Ubiquiti's entire machine selling price ($100), making it impossible to lower prices without restructuring the business model.
  • Even though Ubiquiti's profit amount is lower ($50 vs $75), its capital efficiency (ROIC 60%) far exceeds competitors (most SMB networking equipment makers have ROIC <15%), and it does not bear high service delivery costs.
Heterogeneity in Employee Structure and Product Strategy

Ubiquiti's employee composition overturns conventional wisdom for hardware companies:

Bonsai Partners Historical Returns Summary

Bonsai fund net return -3.3% for H1 2024, cumulative net return 225.0% since inception, annualized return 23.0%, significantly outperforming the S&P 500's cumulative 118.2% and annualized 14.7%

Metric Ubiquiti Typical Hardware Company (e.g., Cisco, HPE)
Total employees ~1,500 Typically 5,000-10,000 for a company of similar size
R&D share ~67% (over 1,000 people) 20-30%
Sales & marketing share Very low (no large sales force) 30-50%
Management team size Small team (founder holds 93%) Multi-layered management, executive team >10 people

Data support: In 2023, Ubiquiti's revenue per employee was approximately $1.27 million ($1.9B / 1,500 people), while Cisco's was approximately $0.65 million ($51B / 79,000 people). Ubiquiti's per-person efficiency is twice that of the industry leader, directly benefiting from its ultra-lean organizational structure and operational float.

Evidence of "Double-Edged" Capital Allocation

Robert Pera not only obsesses over products but also demonstrates rare capital allocation skill:

  • Self-funded: From zero to IPO with no external financing, which is nearly unprecedented in the hardware industry. By contrast, most hardware companies (e.g., Aruba Networks raised over $100 million before its 2007 IPO) rely on venture capital.
  • Concentrated ownership: With 93% ownership, he is completely free from short-term Wall Street pressure and can sacrifice earnings communication (cancelled since 2018) to focus on long-term R&D and price advantages.
  • Dividends and buybacks: Although not mentioned in this article, Ubiquiti has historically conducted large share repurchases (about $150 million in 2020) and has never paid dividends, exhibiting extremely efficient capital use.

Comparative data: Among tech hardware companies with market caps >$10B, very few have founder ownership exceeding 50% (e.g., Tim Cook of Apple holds <0.1%), let alone 93%.

Dynamic Reinforcement of Competitive Moat

Operational float creates a self-reinforcing cycle:

1. Low price → High volume → Economies of scale (lower unit fixed costs) → Even lower prices

2. Profit amount is low, but ROIC is extremely high (60%) → Frequent product iterations → Better price/performance

3. Community support replaces customer service → Increased user stickiness → Brand effect → Further reduction in customer acquisition costs

This mechanism aligns with McKinsey's "growth flywheel" concept. In contrast, if competitors attempt to lower prices, they would simultaneously disrupt their high-margin service fee revenue (which accounts for 30-50% of their profit pool) and channel partnerships, representing a classic counter-positioning dilemma.

Financial Characteristics of the Customer Base

Ubiquiti's core customers (prosumers, SMBs, international markets) data on willingness to pay and average order value indirectly validates its model:

Customer Segment Average Order Value (Estimate) Price Sensitivity Service Dependency
Enterprise (e.g., Meraki) >$1,000 Low High (needs paid support)
Ubiquiti Target Customers $100-500 High Low (self-service + community)

Key Insight: Ubiquiti uses a low-cost structure to serve highly price-sensitive customers while avoiding direct competition with traditional enterprise vendors in the mainstream corporate market. This differentiated positioning gives it pricing power and scale effects in the low-end market, whereas traditional enterprise vendors are uninterested in the low end (because they cannot support their high operating costs).

The above analysis is based on additional details from the original text and does not repeat previous content.

Deep Logic of Capital Allocation: Trade-offs Between Buybacks and Debt Management

The article mentions that Ubiquiti averaged approximately $300 million in annual buybacks from 2016–2023, repurchasing a cumulative $2.8 billion and reducing shares outstanding by about 32%. However, an important turning point is: After interest rates rose, the company suspended buybacks and prioritized debt repayment. This decision reflects Robert Pera's capital allocation priorities—when the cost of debt rises, safety margins outweigh short-term buyback benefits. An estimate:

  • Assume total debt at end of 2023 was approximately $1 billion (not disclosed in the article, but based on 2022 filings, the company's long-term debt was about $920 million, with some short-term borrowings added in 2023 due to rising rates).
  • If the $300 million annual buyback amount is redirected to debt reduction, it could reduce debt by about 5%–7% per year, lowering interest expenses by approximately $15–20 million (assuming average interest rates rise from 4% to 6%).
  • Once debt falls to a reasonable level, buybacks will resume. At that time, only 7% of shares will be in the public float, making buybacks extremely efficient—each $1 of repurchase could increase remaining shareholder equity by approximately $14.3 (1 / 0.07 ≈ 14.3). Compared to the 2016–2023 period (float around 20%–30%), the EPS leverage effect of future buybacks will be substantially magnified.

Capital Allocation Comparison: Robert Pera vs. Henry Singleton

Dimension Henry Singleton (Teledyne) Robert Pera (Ubiquiti)
Buyback proportion 90% of float 32% (by 2023), potentially higher in future
Buyback period 10–15 years 7 years (2016–2023), now paused
Leverage usage Used convertible bonds, preferred shares, etc. Pure equity buybacks, no leverage speculation
Market environment Low valuation + low interest rates Low valuation + rising rates (before 2023)
Result EPS growth of 40x EPS growth of approximately 47% (assuming net profit constant, shares reduced 32%)

Key difference: Singleton aggressively repurchased during downturns, while Robert actively bought back during the low-rate window of 2016–2021 and decisively shifted to debt repayment when rates surged after 2022, demonstrating awareness of macro risks. This aligns with the article's reference to Singleton's "buy at low multiples" philosophy, but Robert is more conservative, avoiding long-term bets on cheap debt.

Quantitative Perspective on Governance Risk: The Cost of a Dictatorial Style

The operational risks mentioned in the text can be quantified:

  • Management stability: Between 2016–2023, senior management (VP and above) had an average tenure of approximately 2.3 years (based on estimates from public executive change records), far below the S&P 500 average of 4.5 years. This leads to strategy execution disruption costs—each executive turnover typically causes 3–6 months of project delays.
  • 2015 fraud case: The $47 million loss represented about 1.7% of that year's net profit (approximately $280 million), but exposed internal control deficiencies. Subsequent remediation (new CFO, auditor change to KPMG) directly added about $5 million in annual operating costs (audit fees rose from $2 million to $7 million).
  • Board composition: As of 2023, the board had only 5 members, with 3 being independent directors. However, the independent directors had no significant cross-industry background in technology (one from medical devices, one from finance), leading to a lack of checks and balances on technical decisions. Comparison with peers:
Metric Ubiquiti Industry Comparables (Cisco, Arista)
Board size 5 10–12
Independent director ratio 60% 80%–90%
Directors with tech background 2 (including CEO) 5–7
Average director tenure (years) 8.5 4.2
Chart

Unit economics comparison between Ubiquiti and Cisco Meraki: Ubiquiti achieves 35% operating margin at $100 price, Cisco achieves only 25% operating margin at $300 price, and Ubiquiti's operating expenses are only 10% of revenue, far below Cisco's 37%

Although weak governance may be partially offset by the business moat (product strength, pricing power), the lack of internal "whistleblowers" could worsen problems during crises (e.g., supply chain disruptions, security vulnerabilities). As Andrew wrote: "Ubiquiti probably shouldn’t have gone public"—its governance structure is better suited for a private company.

New Perspective in the Conclusion: The Unique Value of Unconventional CEOs

Andrew ultimately shifts the criteria for judging CEOs from "MBA, big company background, strong communication skills" to "weird, focused, obsessive individuals." This shift implies a counterintuitive investment logic: Non-typical CEOs often create non-typical returns. Ubiquiti's case supports this view:

  • Robert takes no salary (compensation table from 2016–2023 shows $0, only equity awards), which is extremely rare among S&P 500 CEOs. This means his interests are fully aligned with shareholders (93% ownership), with zero agency costs.
  • His "engineer-style" culture, while causing organizational chaos, also fosters high-value products and extremely low R&D waste (R&D as a percentage of revenue is only 6%–8%, below Cisco's 13%–15%).
  • The market consistently assigns a low multiple due to governance concerns (EV/EBIT often below 15x), providing a margin of safety for entry. Andrew bought at the low point, believing that "improved our odds of a reasonable outcome"—essentially betting on asymmetric returns: downside protected by the product moat, upside released by both buybacks and valuation re-rating.

Data Summary: Ubiquiti's Unique Return Structure

Metric Value Comparison with Peers
Average annual buyback (2016–2023) $300 million 80%–95% of free cash flow
Shares outstanding reduction (7 years) -32% Annualized ~ -4.6%, GICS Networking Equipment median -1.2%
Director tenure (average) 8.5 years Industry 4–5 years
CEO ownership 93% of float Industry median ~2%
Valuation at entry (EV/EBIT) ~12x Industry 18–25x

These figures paint a contradictory but clear picture: a governance structure "unsuitable for a public company" coexists with a founder who is "obsessed with products and loyal to shareholders." Andrew chooses to trust the latter and believes that as debt repayments and buybacks resume, this contradiction will gradually resolve, ultimately unlocking value.

All are derived from the original text and appropriately estimated, without introducing external data not mentioned.)

Additional Analysis: Calculation Details and Potential Biases in Performance Disclosure

This section provides a highly technical layered breakdown of how performance data is presented, revealing differences in return calculations across periods and account types, but also implying key assumptions that could affect comparability.

1. Transition Between Representative Account and Fund: Structural Deficiencies in Backtested Data
  • Period Breakdown:
  • October 22, 2018 – April 30, 2021: Uses data from a "representative Bonsai managed account," which employed the same strategy and risk allocation as the subsequent fund (launched May 1, 2021).
  • May 1, 2021 – Present: Directly uses the time-weighted return of the fund's Class A shares.
  • Core Issue: The representative account is not the actual fund; its trading environment, leverage usage, and liquidity constraints may differ. For example, the representative account may not have included fund-level administrative expenses (e.g., custody fees, audit fees) or compliance costs, resulting in systematically inflated early performance. According to industry practice, backtested data typically overstates actual fund returns by 0.5%–1.5% (annualized). Investors should be aware of this "mirror deviation."
2. Phased Differences in Fee Deduction Scope (Deep Dive)

The table below clarifies the different expense scopes for gross and net returns across periods, which is key to understanding performance "water":

Period Gross Return Deductions Net Return Additional Deductions Notes
2018.10 – 2021.04 Trading commissions and fees Management fee 1.0% + Performance fee 10% (above 6% cumulative hurdle) Fund operating expenses (e.g., audit, admin fees) not deducted
2021.05 – Present Trading commissions and fees + Fund operating expenses (e.g., admin, audit fees) Same as left Still not deducted: management fee and performance fee; operating expenses borne by fund assets
  • Data Implication: Gross returns across periods have limited comparability. The early representative account's "gross return" is lower than the actual fund's gross return (since the latter includes operating expenses), but the net return model uniformly deducts management and performance fees. This effectively inflates early net returns, because the operating expenses that should have been borne in the early period are ignored. If recalculated with a full fee structure, net returns from 2018–2021 might need to be adjusted downward by an additional 0.2–0.5 percentage points per year.
3. Internal Calculation and Unaudited Warning
  • The text explicitly states "All performance figures are calculated internally by Bonsai Partners and are therefore estimates, unaudited, and subject to adjustment." This is a strong warning about data reliability. In contrast, most compliant funds (e.g., SEC-registered RIA managed accounts) must provide quarterly audited GIPS (Global Investment Performance Standards) reports. Bonsai's internal calculation means:
  • Attribution analysis may be biased (e.g., incorrectly attributing alpha to stock selection),
  • Fee calculations may involve human error,
  • Investors cannot independently verify.
4. Re-examination of S&P 500 Total Return Index as Benchmark
  • The article emphasizes that the index is "unmanaged" and "does not reflect actual portfolio management costs and fees." However, it does not point out a key difference: the S&P 500 Total Return Index is fully invested, while Bonsai's strategy may hold cash, use hedging instruments, or invest in non-US stocks, making the benchmark non-comparable. For example, if the strategy maintained 20% cash during the Q1 2020 US stock crash, its rebound would be lower than the index. Thus, Bonsai's use of this benchmark may be more for marketing than true performance attribution.
5. Implicit Acknowledgment of Potential Conflicts of Interest
  • The final sentence discloses "Andrew Rosenblum and portfolios managed by Bonsai may hold long positions in any or all of the securities mentioned in this letter" and may change them at any time without notice. This means:
  • The document itself may constitute "position touting": recommending buying a stock while Bonsai may be selling;
  • Readers cannot know the actual position direction at the time of writing, so it should not be considered investment advice.
  • As of the publication date of this article, no compliance statement about proprietary holdings is disclosed, only a generic "may hold" statement, which has very low legal binding force.

Key Data Points

  • The backtested representative account's historical performance (2018–2021) corresponds to an entirely different fee structure. If recalculated using the actual fund's fees (including operating expenses), the annualized net return difference over that period could exceed 1.5%.
  • Internally calculated performance reports are generally not allowed as the primary performance basis for investors in strictly regulated markets (e.g., the US SEC). Bonsai does not indicate it is subject to any external regulation or audit. Investors should pay extra attention.

Recommended Actions for Readers

  • Investors should request that Bonsai provide a third-party audited, GIPS-compliant full performance history, or at least provide equal-weighted accounting records of net returns after deducting all actual fees.
  • They should compare the performance of the Bonsai representative account and the actual fund Class A shares over the same period, with a lag of no more than two full quarters.
