This episode breaks down Goldman Sachs, a 150-year-old investment bank. Analyst Marc Rubinstein says Goldman isn't a 'vampire squid' or a miracle—it's a complex risk intermediary (helping clients manage financial risks like IPOs, M&A, and trading). Its revenue is cyclical, but its scale and $4B+ annual tech spending are widening its lead. Key holdings: Goldman Sachs (target ROE 14%-16%, but cyclical), JPMorgan (tied #1 in investment banking, #1 in fixed income), and Blackstone (a private equity firm that competes without bank regulations).
Goldman Sachs, an investment bank with a 150-year history, operates across three core segments: Investment Banking, Sales & Trading, and Asset Management, with over $1 trillion in assets under management. The report argues that Goldman Sachs is neither a "vampire squid" nor a "work of God," but rath
Long-time financial industry analyst Marc Rubinstein (20 years of sell-side research + 10 years of hedge fund partner experience, having invested in Goldman Sachs and served as its client) and host Matt Reustle (former Goldman Sachs employee) deconstruct this 150-year-old investment bank. Rubinstein's core judgment is that Goldman Sachs is neither a "vampire squid" nor a "work of God," but a complex financial institution at the center of the financial system, with highly cyclical businesses, yet consolidating its market position through scale and brand—the core logic of its valuation lies in the comparison of "ROE versus cost of equity," rather than traditional P/E ratios.
Rubinstein argues that the key to understanding Goldman Sachs lies in its role as a "risk intermediary."
The core function of an investment bank is to help clients manage risk—clients have risks they do not want, or seek risks they do not have, and Goldman Sachs facilitates this in the middle. This takes three specific forms:
1. Actively assuming risk: Taking on risk using its own balance sheet, such as underwriting IPOs or acting as a counterparty in securities trades.
2. Matching risk: Transferring risk between different clients. Rubinstein cites the oil industry as an example—the Mexican government wants to hedge against falling oil prices, while airlines want to hedge against rising oil prices, and Goldman Sachs matches them in the middle.
3. Creating risk: Using structured products, derivatives, and other instruments to provide institutional investors with the risk exposure they desire.
"They trade in risk" — this is Rubinstein's summary of the fundamental nature of investment banking.
Rubinstein argues that Goldman Sachs’s reputational collapse after the financial crisis stemmed from a critical timing mismatch: accepting a government bailout in 2008, then posting its highest-ever revenues in 2009.
Rubinstein points to a counterintuitive lesson: maximizing profits does not necessarily equate to maximizing shareholder value. In certain contexts, an excessive pursuit of short-term profits can damage long-term reputation and shareholder interests.
The most straightforward fee model—charging a percentage of transaction value:
Goldman Sachs and JPMorgan are tied for first place in global investment banking, each holding a market share of 15%-20% across product lines. In 2021, global M&A transaction volume reached $1 trillion, and a fee rate of 0.5%-0.6% translates into substantial revenue.
Rubinstein calls this a "black box"—the hardest business line to predict.
Revenue comes from two sources:
1. Market-making spreads: The difference between bid and ask prices. The key variable is volatility—the higher the volatility, the wider the spread, and the greater the profit margin for market makers. Rubinstein distinguishes between "good volatility" (fluctuations within a range, conducive to widening spreads) and "bad volatility" (extreme fluctuations, posing risk management challenges)
2. Financing business: Margin loans, prime brokerage, warehouse loans, corporate loans, etc. Historically, it has consistently contributed approximately $5 billion per year
Historical revenue range:
| Business Line | Annual Revenue Range |
|---|---|
| Fixed income market-making | $5-10 billion |
| Equity market-making | $4-8 billion |
| Financing business | ~$5 billion |
| Total | $14-16 billion |
The most stable revenue source. Goldman Sachs manages $2.5 trillion in assets, charging approximately 0.2% management fees on third-party assets, plus some performance fees.
Notably, Goldman Sachs' asset management business still involves a significant amount of proprietary capital investment (accounting for the bulk of approximately $11 billion in revenue), but the company's strategic direction is to reduce proprietary capital deployment and increase third-party managed assets in exchange for more stable, capital-light revenue.
A new business line, including the Marcus online bank and ultra-high-net-worth wealth management. It has attracted over $350 billion in deposits.
Rubinstein presents a concise valuation framework: treat the bank as a "bond" and compare its ROE with the cost of equity.
Rubinstein emphasizes that understanding bank valuation requires first understanding its balance sheet structure:
| Metric | Pre-Financial Crisis (2006-07) | Current |
|---|---|---|
| Capital size | ~$35 billion | ~$100 billion |
| Balance sheet size | Smaller but riskier | $1.5 trillion, but safer |
| Leverage ratio | Extremely high | Significantly reduced |
| Level 3 assets (hard to value) | Large amount | ~$25 billion, very small proportion |
The largest asset category on Goldman Sachs' current balance sheet is sales and trading inventory (about one-third), along with a substantial amount of cash-like assets (liquidity requirements).
Rubinstein’s assessment: the big get bigger, with the top three capturing an increasing share.
| Business Line | Goldman Sachs Rank | Market Share |
|---|---|---|
| Investment Banking (M&A + Underwriting) | #1 (tied with JPMorgan) | 15%-20% |
| Equity Trading | #1 (tied with Morgan Stanley) | ~20% |
| Fixed Income | #3 (behind JPMorgan and Citi) | — |
Drivers: Scale of technology investment—Goldman Sachs spends over $4 billion annually on technology, a level unattainable for smaller players. Compensation as a percentage of revenue has fallen from 50% 20 years ago to 30%, while the importance of technology/infrastructure spending has risen.
Rubinstein believes traditional competition is already fully priced in; the real threats come from:
1. Private equity firms (e.g., Blackstone): not subject to bank regulatory constraints, competing directly with Goldman Sachs in capital provision
2. Boutique investment banks: established players in M&A advisory (e.g., Lazard) and emerging firms
3. Tech company + bank partnerships: Rubinstein views the most formidable competitor as a combination of "Goldman Sachs + a consumer tech company"—the tech firm brings distribution and trust, while Goldman Sachs provides risk management and a balance sheet
Rubinstein places special emphasis on the importance of culture. Although Goldman Sachs is publicly listed, it has retained its partnership system—440 partners (out of approximately 45,000 total employees) form the core network. This scale is close to Dunbar’s number (150-500), enabling cross-departmental collaboration.
Host Reustle added an insight into the internal culture: "From day one, they teach you—you don’t need to know the answer; you need to know who knows the answer."

1. "Investment banks trade in risk" (Rubinstein) — Three roles: actively assuming, matching, and creating risk. This is the starting point for understanding all investment banking operations.
2. Goldman Sachs' record revenue in 2009 ($45 billion) was the root of brand damage (Rubinstein) — Announcing the highest profit in history right after receiving government bailouts; profit maximization ≠ shareholder value maximization.
3. Bank valuation = comparing ROE with cost of equity (Rubinstein) — 15% ROE / 10% cost of equity = 1.5x price-to-book ratio. This is the most concise valuation framework.
4. Compensation-to-revenue ratio dropped from 50% to 30%, with technology spending becoming the new moat (Rubinstein) — Goldman Sachs invests over $4 billion annually in technology; smaller players cannot catch up. This is the core driver of market concentration.
5. "Good volatility" vs. "Bad volatility" (Rubinstein) — Volatility within a range widens market-making spreads (good), while extreme volatility creates risk management issues (bad). This is the key framework for forecasting trading revenue.
6. The most fearsome competitor = Goldman Sachs + consumer technology company (Rubinstein) — Tech companies have distribution and trust; Goldman Sachs has risk management and a balance sheet. The combination of the two is the most powerful force in financial services.
7. The 440-partner system is the core of Goldman Sachs' culture (Rubinstein) — Close to Dunbar's number, ensuring cross-department collaboration and institutional memory. It is key to maintaining a "small company culture" within a 45,000-person organization.
8. SPACs are more profitable than IPOs (Rubinstein) — From M&A fees to distribution fees, the entire SPAC process generates higher profit contributions for investment banks than traditional IPOs, refuting the claim that "SPACs are an alternative to IPOs."
