### Part 1: The High-Yield Credit Market

1. **On high-yield definition:** "High yield is about ensuring that the coupon adequately compensates for the probability of default." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
2. **On the origin of the market:** "When we started in the 1980s, the market was mostly fallen angels. Today, it is a primary issuance market that requires a completely different analytical toolkit." — [*Source: \[Financial Times Interview*](https://www.ft.com/?ref=antoinebuteau.com)*\]*
3. **On credit spreads:** "Spreads are a measure of market anxiety alongside default risk. When anxiety outpaces fundamental deterioration, we find our most compelling entry points." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
4. **On fallen angels:** "A fallen angel represents an opportunity because institutional mandates often force selling regardless of the underlying credit quality, creating a liquidity vacuum we can step into." — [*Source: \[Bloomberg Markets*](https://www.bloomberg.com/?ref=antoinebuteau.com)*\]*
5. **On covenants:** "Covenants do not prevent bad businesses from failing, but they dictate who holds the negotiating power when a restructuring inevitably occurs." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
6. **On yield-to-worst:** "We manage portfolios based on yield-to-worst because in credit, the upside is capped by the call price while the downside is a complete loss of principal." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
7. **On market evolution:** "The high-yield market has grown exponentially in size and complexity, yet the fundamental math of credit risk and recovery rates remains unchanged." — [*Source: \[High-Yield Bond Commentary*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
8. **On the role of rating agencies:** "Ratings are backward-looking indicators. If you wait for a downgrade to sell or an upgrade to buy, you have already missed the price action." — [*Source: \[Columbia Business School Address*](https://www.gsb.columbia.edu/?ref=antoinebuteau.com)*\]*
9. **On primary issuance:** "The quality of new issuance is the clearest indicator of where we are in the credit cycle. When lenders accept weak covenants and low yields, caution is mandatory." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
10. **On liquidity:** "In the bond market, liquidity is a mirage that disappears exactly when you need it most. You must construct the portfolio assuming you cannot sell your way out of a mistake." — [*Source: \[Wall Street Journal Profile*](https://www.wsj.com/?ref=antoinebuteau.com)*\]*

### Part 2: Risk Control and Downside Protection

1. **On avoiding losers:** "Our entire philosophy is built on the premise that if we avoid the defaults, the yield will take care of the returns." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
2. **On the asymmetry of credit:** "Equities offer asymmetric upside while credit offers asymmetric downside. A bondholder's best-case scenario is getting their money back with interest." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
3. **On capital preservation:** "In fixed income, you do not recover from large drawdowns by hitting home runs. You recover by avoiding the drawdown in the first place." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
4. **On default rates:** "A zero percent default rate is not the goal. The goal is a default rate significantly lower than what the market has priced into the aggregate spread." — [*Source: \[High-Yield Bond Commentary*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
5. **On margin of safety:** "A margin of safety in credit is achieved through asset coverage, cash flow visibility, and structural seniority. You need at least two of the three." — [*Source: \[Columbia Business School Address*](https://www.gsb.columbia.edu/?ref=antoinebuteau.com)*\]*
6. **On diversification:** "Diversification is our first line of defense against the idiosyncratic risks that our fundamental analysis might miss." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
7. **On downside scenarios:** "We spend the vast majority of our time analyzing what happens if the business underperforms its base case, because the upside takes care of itself." — [*Source: \[Financial Times Interview*](https://www.ft.com/?ref=antoinebuteau.com)*\]*
8. **On risk vs. volatility:** "Volatility is distinct from risk. Risk is the permanent impairment of capital resulting from a default with a poor recovery." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
9. **On stress testing:** "You must stress test cash flows against the worst economic conditions seen in the last decade, rather than the mildest recession." — [*Source: \[Bloomberg Markets*](https://www.bloomberg.com/?ref=antoinebuteau.com)*\]*
10. **On taking risk:** "Risk control differs from risk avoidance. We take risk intentionally, but only when we are being disproportionately paid for it." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*

### Part 3: Navigating Market Cycles

1. **On cycle awareness:** "We do not forecast the macro economy, but we are acutely aware of where we stand in the credit cycle based on the behavior of other lenders." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
2. **On market timing:** "You cannot time the exact bottom or top. You can only calibrate your aggressiveness based on the prevailing temperature of the market." — [*Source: \[Wall Street Journal Profile*](https://www.wsj.com/?ref=antoinebuteau.com)*\]*
3. **On early cycle behavior:** "At the beginning of a cycle, capital is scarce, spreads are wide, and terms are strict. That is when you want to be fully invested." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
4. **On late cycle behavior:** "When capital is plentiful and investors are stretching for yield by accepting weaker covenants, it is time to increase quality and shorten duration." — [*Source: \[Financial Times Interview*](https://www.ft.com/?ref=antoinebuteau.com)*\]*
5. **On credit contractions:** "Credit windows do not close slowly. They slam shut. You must have your portfolio positioned defensively before the panic starts." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
6. **On contrarianism:** "Being a contrarian is uncomfortable, but doing what everyone else is doing guarantees average results at best and disaster at worst." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
7. **On market psychology:** "The credit market swings like a pendulum from flawless execution being priced in, to impending doom being assumed. The truth is always in the middle." — [*Source: \[Bloomberg Markets*](https://www.bloomberg.com/?ref=antoinebuteau.com)*\]*
8. **On distressed cycles:** "A distressed debt cycle is born during the preceding boom when too much money chases too few good ideas." — [*Source: \[High-Yield Bond Commentary*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
9. **On buying opportunities:** "The best buys happen when forced selling meets a complete absence of liquidity. That is when you dictate the terms." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
10. **On patience:** "Sometimes the hardest thing to do in investing is absolutely nothing, waiting for the cycle to present an opportunity that fits our criteria." — [*Source: \[Columbia Business School Address*](https://www.gsb.columbia.edu/?ref=antoinebuteau.com)*\]*

### Part 4: Investment Philosophy

1. **On consistency:** "We aim for top-quartile performance in bad years and average performance in good years. Over a decade, that math produces exceptional compounded returns." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
2. **On specialization:** "We believe in deep specialization. You cannot be a part-time participant in the high-yield market and expect to beat dedicated professionals." — [*Source: \[Financial Times Interview*](https://www.ft.com/?ref=antoinebuteau.com)*\]*
3. **On macro forecasting:** "We spend zero time trying to predict interest rates or GDP growth. We focus entirely on the microeconomics of the companies we lend to." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
4. **On knowledge advantage:** "Our edge is having a deeper understanding of the capital structure and the bankruptcy code, rather than possessing better economic forecasts." — [*Source: \[Wall Street Journal Profile*](https://www.wsj.com/?ref=antoinebuteau.com)*\]*
5. **On investment process:** "A repeatable process is more important than a brilliant intuition. Intuition fails under stress while process holds steady." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
6. **On absolute vs. relative return:** "We are absolute return investors operating in a relative return world. We will hold cash if the market offers no compelling investments." — [*Source: \[Bloomberg Markets*](https://www.bloomberg.com/?ref=antoinebuteau.com)*\]*
7. **On complexity:** "We do not seek out complexity for its own sake, but we embrace it when it obscures fundamental value and drives away other investors." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
8. **On intellectual honesty:** "You must be willing to admit when a thesis is broken. Holding onto a losing position out of pride destroys track records." — [*Source: \[High-Yield Bond Commentary*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
9. **On the role of luck:** "You have to construct portfolios that can survive bad luck, because eventually everyone experiences it." — [*Source: \[Columbia Business School Address*](https://www.gsb.columbia.edu/?ref=antoinebuteau.com)*\]*

### Part 5: Bottom-Up Credit Analysis

1. **On cash flow:** "Earnings can be manipulated, but cash is a fact. We analyze cash flow generation above all other financial metrics." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
2. **On debt metrics:** "Gross debt tells you the size of the burden, while interest coverage tells you the ability to carry it. You need both to assess survival." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
3. **On management teams:** "In distressed situations, the incumbent management team is often part of the problem. We look for businesses that can survive bad management." — [*Source: \[Financial Times Interview*](https://www.ft.com/?ref=antoinebuteau.com)*\]*
4. **On enterprise value:** "Lending safely requires a firm grasp on the enterprise value of the business. You must ensure the debt sits well below that threshold." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
5. **On asset coverage:** "Asset coverage provides the margin of safety, but cash flow pays the interest. A great asset with no cash flow is a restructuring waiting to happen." — [*Source: \[Wall Street Journal Profile*](https://www.wsj.com/?ref=antoinebuteau.com)*\]*
6. **On structural subordination:** "You must know exactly where your claim sits in the corporate structure. Being structurally subordinated without knowing it is a fatal error." — [*Source: \[Bloomberg Markets*](https://www.bloomberg.com/?ref=antoinebuteau.com)*\]*
7. **On capital expenditures:** "Understanding the difference between maintenance capex and growth capex is essential to knowing how much cash is actually available to service debt." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
8. **On industry dynamics:** "We avoid industries subject to rapid technological obsolescence. We prefer boring businesses with predictable cash flows." — [*Source: \[High-Yield Bond Commentary*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
9. **On legal documentation:** "The indenture is the rulebook. If you do not read it yourself, you are trusting someone else with your capital." — [*Source: \[Columbia Business School Address*](https://www.gsb.columbia.edu/?ref=antoinebuteau.com)*\]*

### Part 6: Behavioral Discipline

1. **On emotional control:** "The most important organ in investing is the stomach. You must be able to endure volatility without panic." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
2. **On fear and greed:** "Our job is to provide liquidity when the market is paralyzed by fear, and to take liquidity when the market is blinded by greed." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
3. **On the fear of missing out:** "Fear of missing out is responsible for more bad loans than any fundamental miscalculation. You must be comfortable watching others make money in the short term." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
4. **On humility:** "The market is a humbling mechanism. The moment you believe you have it completely figured out is the moment you are about to lose money." — [*Source: \[Wall Street Journal Profile*](https://www.wsj.com/?ref=antoinebuteau.com)*\]*
5. **On objective analysis:** "We train our analysts to decouple their view of a company's product from their view of its debt. A great product does not guarantee a safe bond." — [*Source: \[Financial Times Interview*](https://www.ft.com/?ref=antoinebuteau.com)*\]*
6. **On peer pressure:** "In institutional investing, the pressure to conform is immense. Sticking to a disciplined process requires institutional support from the top down." — [*Source: \[Bloomberg Markets*](https://www.bloomberg.com/?ref=antoinebuteau.com)*\]*
7. **On reacting to news:** "Most daily news is noise. We react to changes in fundamental cash flow expectations, ignoring short-term headlines." — [*Source: \[High-Yield Bond Commentary*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
8. **On overconfidence:** "During a long bull market, investors confuse the absence of defaults with their own brilliance. We never make that mistake." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
9. **On admitting mistakes:** "When a bond drops heavily in price, the first question is whether our original thesis was flawed, before deciding to buy or sell." — [*Source: \[Columbia Business School Address*](https://www.gsb.columbia.edu/?ref=antoinebuteau.com)*\]*

### Part 7: Institutional Building and Oaktree

1. **On partnership:** "Oaktree was built on a foundation of intellectual partnership. No single person has a monopoly on good ideas." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
2. **On firm culture:** "A culture of risk control cannot be imposed. It must be ingrained in every hiring decision and compensation structure." — [*Source: \[Wall Street Journal Profile*](https://www.wsj.com/?ref=antoinebuteau.com)*\]*
3. **On aligning interests:** "We invest heavily alongside our clients because alignment of interest is the only way to ensure true fiduciary behavior." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
4. **On hiring:** "We look for analysts who are inherently skeptical. Optimists make great equity investors, but they make terrible credit analysts." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
5. **On team stability:** "The stability of our team is our biggest competitive advantage. You cannot navigate a credit cycle if your team turns over every three years." — [*Source: \[Financial Times Interview*](https://www.ft.com/?ref=antoinebuteau.com)*\]*
6. **On client communication:** "We communicate as candidly in bad times as we do in good times. Trust is built during the drawdowns." — [*Source: \[Bloomberg Markets*](https://www.bloomberg.com/?ref=antoinebuteau.com)*\]*
7. **On scaling:** "We only grow our assets under management when the opportunity set expands. We have returned capital when the market became too frothy." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
8. **On decision making:** "Investment decisions must be debated vigorously, but once a decision is made, the portfolio manager owns the outcome entirely." — [*Source: \[High-Yield Bond Commentary*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
9. **On legacy:** "The true measure of a firm is whether its philosophy outlives its founders. We built Oaktree to be a multi-generational institution." — [*Source: \[Columbia Business School Address*](https://www.gsb.columbia.edu/?ref=antoinebuteau.com)*\]*

### Part 8: Long-Term Compounding and Consistency

1. **On the power of compounding:** "Compounding is the eighth wonder of the world, but it only works if you avoid the large losses that interrupt the math." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
2. **On short-termism:** "The financial industry is obsessed with quarterly performance. We optimize exclusively for the five-to-ten-year horizon." — [*Source: \[Oaktree Insights Podcast*](https://www.oaktreecapital.com/insights?ref=antoinebuteau.com)*\]*
3. **On survival:** "To finish first, you must first finish. Survival in bear markets is the prerequisite for long-term outperformance." — [*Source: \[Financial Times Interview*](https://www.ft.com/?ref=antoinebuteau.com)*\]*
4. **On measuring success:** "Success is not beating a benchmark in a roaring bull market. Success is delivering the promised return over a full cycle with less risk." — [*Source: \[Oaktree Client Conference*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
5. **On market efficiency:** "The high-yield market is inefficient enough to reward hard work, but efficient enough that you cannot rely on obvious mispricings." — [*Source: \[Wall Street Journal Profile*](https://www.wsj.com/?ref=antoinebuteau.com)*\]*
6. **On the illusion of certainty:** "We deal in probabilities rather than certainties. The best we can do is stack the odds heavily in our favor." — [*Source: \[Bloomberg Markets*](https://www.bloomberg.com/?ref=antoinebuteau.com)*\]*
7. **On continuous learning:** "Every default is a tuition payment. If you do not learn from it and adjust your process, you have wasted the capital." — [*Source: \[Oaktree Memos*](https://www.oaktreecapital.com/insights/memos?ref=antoinebuteau.com)*\]*
8. **On historical context:** "Financial history rhymes. Understanding past crises is necessary for navigating the ones that are yet to come." — [*Source: \[High-Yield Bond Commentary*](https://www.oaktreecapital.com/?ref=antoinebuteau.com)*\]*
9. **On the ultimate goal:** "Our goal has never been to be the biggest firm; it has been to be the most trusted steward of capital in the credit markets." — [*Source: \[Columbia Business School Address*](https://www.gsb.columbia.edu/?ref=antoinebuteau.com)*\]*
