Comment investir en Bourse comme Warren Buffett ? Les 7 conseils clés
7 conseils pour investir en Bourse comme Warren Buffett en vidéo
1. Respectez votre cercle de compétences
Pour Warren Buffett, « The risk comes from not knowing what you’re doing. »
Invest in only the companies you understand well. This may seem obvious, but many people wrongly think they will pass up opportunities if they limit their investment universe.
Yet Warren Buffett insists:
« There are all kinds of businesses that Charlie [Charlie Munger is Warren Buffett’s principal business partner] and I don’t understand, but we don’t lose sleep over them. That just means we move on to the next one, and that’s what the individual investor should do. »
2. Invest in high-quality companies
« It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price. »
So be patient! You don’t have a gun to your head. There is no rush. Be patient and invest in high-quality businesses when their prices become reasonable. You will take on less risk and achieve better results.
3. Évitez les sociétés à la mode
According to Warren Buffett, « Most people are interested in stocks when everyone is interested. The time to be interested is when no one else is. You cannot buy what is in sight and expect to succeed. »
The Oracle of Omaha’s principles help avoid FOMO, the fear of missing out on a hot opportunity that pushes you to invest in any trendy asset or sector just because its price is rising. Do not buy shares of a company after reading a glowing article. Everyone will have the same idea! And beware of fashion trends; they have created speculative bubbles! Do not fall into the current enthusiasm around artificial intelligence, for example. Also, do not take analysts’ recommendations at face value, as they can be contradictory.
Form your own view and don’t hesitate to venture beyond the beaten path of CAC 40 stocks: for example by diversifying your investments with thematic ETFs that can be a good way to invest in the stock market.
It is nonetheless possible to invest in fashionable companies and Buffett has even bought Apple or Amazon shares, but you should never buy companies solely because they are in vogue. Your stock picking should be based on fundamentals, valuation and understanding of the company’s business model.
4. Optez pour des entreprises simples et fidèles à leur métier de base
Warren Buffett shares: « I invest in companies so wonderful that they can be run by an idiot. For sooner or later, that will happen. »
Invest in companies that are simple to understand and easy to manage. If a business is too complex, stay away. You won’t be able to evaluate it. Favor companies that stay true to their core activity, such as Coca-Cola.
5. Soyez patient, très patient !
Warren Buffett is categorical: « Only buy what you would be perfectly happy to hold if the market shut down for 10 years. »
Avoid following stock market news day by day, as you may find that stock prices do not move fast enough. The temptation to use leverage will be greater. Yet, while leverage can multiply gains, it also multiplies losses!
It’s hard not to think of real estate, a favorite French investment, when you hear this Buffett quote: “Our preferred investment horizon is forever.”
Real estate is indeed a tangible asset, decoupled from the financial markets, and it’s worth considering to diversify your portfolio with complementary stock market investments.
6. Si vous vous êtes trompé, ne persistez pas, vendez !
Warren Buffett expresses this common-sense idea: « If you ever find yourself on a sinking boat, the energy to change boats is more productive than the energy to patch holes.»
In other words, don’t stubbornly cling to a losing position; sell!
7. Restez à l’écart de la folie qu’entraîne la fluctuation des marchés
« See market fluctuations as your ally rather than your enemy; profit from the madness rather than participate in it. »
Buffett emphasizes the importance of a certain detachment and goes further by encouraging the opposite of the trend: « We simply try to be nervous when others are greedy and greedy when others are nervous. »
In conclusion, analyze your successes as well as your mistakes. According to Warren Buffett, « In business, the rearview mirror is always clearer than the windshield. » Use this to understand what you did right and how, and where you failed and why!
Finally, don’t forget Warren Buffett’s golden rule: « Rule number one: don’t lose money; rule number two: never forget rule number one.
Warren Buffett : que dit la dernière lettre aux actionnaires de Berkshire Hathaway ?
In the latest Berkshire Hathaway shareholder letter, Warren Buffett delivered not only numbers but also timeless investment principles. True to Berkshire Hathaway’s DNA, he stressed discipline in capital allocation, patience and the search for solid, well-managed companies capable of generating durable profits.
Buffett highlighted the importance of a long-term vision, far from daily market fluctuations. He explained that accumulating cash is not a sign of inaction but a demonstration of prudence, because it is better to wait for the right opportunity than to succumb to current euphoria. He also reminded that performance depends less on timing than on the quality of the assets held and the consistency of the strategy.
Finally, Warren Buffett stressed a key principle: protecting capital remains a priority. Growth comes later. A simple, yet always relevant lesson for any stock market investor.
In 2026, Berkshire Hathaway’s cash reserves remained near historic highs, above $340 billion. This record level concretely illustrates Buffett’s message of prudence in the latest Berkshire Hathaway shareholder letter. When valuations look high, patience can be a real strategy. Keeping cash does not reflect inaction but a readiness to seize major opportunities when a cycle turns.
Comment investir comme Warren Buffett ? Son portefeuille Bourse 2026 décrypté
As Berkshire Hathaway’s market capitalization has now surpassed $1 trillion, the overall value of Berkshire Hathaway’s portfolio stood at $267 billion as of September 30, 2025 (disclosed to the SEC on November 14, 2025). The most recent filing published at the end of 2025 confirms the continued tightening of Berkshire Hathaway’s listed portfolio, whose value slightly contracted due to the gradual reductions in Apple and Bank of America, while the group’s cash remains at historically high levels, reflecting a prudent strategy in a challenging market environment.
Discover the composition of Warren Buffett’s stock portfolio from his SEC filing of November 14, 2025, as well as our analysis and opinion on Warren Buffett’s stock portfolio!
Note that this is in fact the portfolio of Buffett’s fund, Berkshire Hathaway Inc. It should be noted that Buffett also holds stakes in JPMorgan Chase and Wells Fargo for amounts that are not publicly disclosed.
Composition of Warren Buffett’s stock portfolio as of September 30, 2025 (reported to the SEC on November 14, 2025)
Action Apple
Apple shares represent 22.69% of Warren Buffett’s portfolio, standing at a value of about $60.65 billion as of September 30, 2025.
Throughout 2025, Berkshire Hathaway significantly adjusted its position in Apple, not by strategic divestment, but by optimizing a position that had grown very large after the stock’s substantial rise.
During 2025, 72,082,192 Apple shares were sold, distributed as follows:
- Second quarter 2025: sale of 20,000,000 shares
- Third quarter 2025: sale of 41,787,236 shares
- Fourth quarter 2025: sale of 10,294,956 shares
Considering an average annual price in 2025 of about $231 for Apple stock, these disposals amount to roughly $16.65 billion in gross sales. Based on an estimated average cost of around $39.60 per Apple share, the realized gain in 2025 is about $13.78 billion.
Despite these reductions, Berkshire Hathaway still held nearly 238 million Apple shares by the end of 2025, leaving a substantial latent gain. Apple remains the largest position in Warren Buffett’s portfolio.
These moves illustrate an active and disciplined management of a historic position, without calling into question the long-term conviction in Apple.
Action American Express
American Express shares represent 18.84% of Warren Buffett’s stock portfolio, i.e., a valuation of $50.35 billion as of September 30, 2025.
The Berkshire Hathaway fund has long maintained a meaningful position in American Express. Buffett has always particularly appreciated this business for its unique model and its strong position in the credit card market. American Express benefits from exceptional brand recognition and high customer loyalty, factors Buffett values greatly. Despite challenges, Warren Buffett chose to hold onto his shares, demonstrating his confidence in the company’s resilience and long-term potential.
In 2025, Warren Buffett neither bought nor sold any American Express shares.
Action Bank Of America
Bank of America shares represent 10.96% of Warren Buffett’s portfolio, i.e., a valuation of $29.3 billion as of September 30, 2025.
Buffett’s position in Bank of America was relatively small (less than 1%) between 2007 and mid-2017. It was from the 3rd quarter of 2017 that the famous investor decided to invest nearly 10% of his portfolio in Bank of America shares, which he acquired at $25. He then increased his stake in the 3rd quarter of 2020 by purchasing an additional 85 million Bank of America shares.
Following a new investment in Q1 2023 of 22.7 million Bank of America shares, Berkshire Hathaway held a position approaching 1 billion Bank of America shares, valued at around $45 billion.
In 2025, Berkshire Hathaway significantly reduced its stake in Bank of America, reflecting a less assertive strategic conviction than in the past but a plan to take profits as the stock advanced. Over the year, several tens of millions of shares were sold, distributed as follows:
- First quarter 2025: 48,660,156 shares sold
- Second quarter 2025: 26,306,156 shares sold
- Third quarter 2025: 37,187,363 shares sold
- Fourth quarter 2025: 50,774,078 shares sold
In total, 162,927,753 shares were sold during the year.
Taking as a reference an indicative average price around $46.6 in 2025 (approximate annual average of observed prices for the year), these sales represent nearly $7.59 billion in gross value. Even though Berkshire trimmed its position, the gradual reduction reflects a profit-taking strategy in a banking sector that performed well during the year, rather than a rejection of the title.
Action Coca Cola
The Coca-Cola shares represent 9.92% of Warren Buffett’s stock portfolio, i.e., a valuation of $26.5 billion as of September 30, 2025.
Often described as the textbook case of yield investing (the dividend aristocrat), Coca-Cola is part of Warren Buffett’s portfolio mainstays. He has held his 400 million Coca-Cola shares for a long time.
In 2025, Warren Buffett neither sold nor bought new Coca-Cola shares.
Action Chevron
Chevron shares represent 7.09% of Warren Buffett’s portfolio, i.e., a valuation of $18.9 billion as of September 30, 2025.
While Buffett began investing in the oil group in late 2020, it was in early 2022 that he increased his stake in Chevron significantly with a total purchase of more than 126 million Chevron shares for $18.8 billion. In the first quarter of 2024, Buffett reduced his exposure by selling 3 million Chevron shares, followed by another 4 million shares in the second quarter of 2024.
In 2025, Berkshire Hathaway reinforced its position in Chevron, illustrating a dynamic opposite to what was seen in several other lines of Buffett’s portfolio. The purchases were as follows:
- Second quarter 2025: acquisition of 3,454,358 shares
- Fourth quarter 2025: acquisition of 8,091,570 shares
In total, this amounts to 11,545,928 Chevron shares bought in 2025.
Assuming a reasonable average annual price of around $150 to $155 for Chevron in 2025, these purchases correspond to a rough gross outlay of between $1.73 billion and $1.79 billion.
These movements confirm a strategy of gradual accumulation in the energy sector, reflecting Berkshire’s belief in the growth and yield potential of the group, even amid volatility in oil prices and refining margins.
Action Occidental Petroleum
Occidental Petroleum shares represent 4.68% of Warren Buffett’s portfolio, i.e., a valuation of $12.5 billion as of September 30, 2025.
While Buffett had fully liquidated Occidental Petroleum shares in 2020, he bought back almost 200 million shares in 2022: an initial purchase of 136 million shares in early 2022 and two additional purchases of 22 and 36 million shares.
In the first quarter of 2025, Berkshire Hathaway increased its position in Occidental Petroleum by purchasing 763,017 shares, showing a willingness to benefit from attractive valuations in the energy sector at the start of the year.
These purchases were made at a weighted average price of about $46.82 per share, for a total outlay of around $35.7 million according to data available on transactions executed in February 2025.
This accumulation fits into Berkshire’s broader strategy to diversify its energy holdings, complement its existing exposures and bet on companies with strong yield potential in a context of relatively sustained oil prices.
Action Moody’s
Moody’s shares represent 4.40% of Warren Buffett’s stock portfolio, i.e., a valuation of $11.7 billion as of September 30, 2025.
One could admit Buffett had a flair when he decided to acquire 48 million Moody’s shares more than 15 years ago! He reduced his position to 31 million shares by the end of 2009, and to 25 million shares by mid-2013. He may regret it somewhat because Moody’s traded at $485 per Moody’s share on June 10, 2025, while Buffett had reduced his stake by two increments of 18% at price levels between $20 and $27 in 2009.
Today, he holds “only” 24 million Moody’s shares of the famous credit rating, research and analytics company.
Action Chubb Limited
Chubb Limited shares represent 3.31% of Warren Buffett’s portfolio, i.e., a valuation of $8.8 billion as of September 30, 2025.
Investment in Chubb Limited fits perfectly with Berkshire Hathaway’s historical logic: the group has always favored solid insurers capable of generating a substantial float (premiums collected before claims payouts), offering a stable and low-cost financial leverage. Chubb stands out for the quality of its underwriting, disciplined pricing, and high profitability in high-end property and casualty insurance.
In 2025, Berkshire Hathaway increased its position in Chubb Limited, confirming strategic interest in the insurance sector:
- Third quarter 2025: 4,299,111 shares
- Fourth quarter 2025: 2,916,288 shares
In total, 7,215,399 shares were acquired during the year. Assuming an indicative average price of around $285 in 2025, these purchases amount to an investment of about $2.06 billion.
This rise in stake reflects a desire to strengthen exposure to a profitable, disciplined and resilient insurer, criteria historically dear to Berkshire Hathaway.

Quels sont les secrets du portefeuille actions de Warren Buffet en 2026 ?
Une stratégie ressort clairement lorsque l’on étudie le portefeuille de Warren Buffet : la confiance dans ses investissements à long terme !
En effet, on remarque que ses grandes convictions d’il y a quelques décennies sont souvent toujours en portefeuille, notamment pour ses principales positions telles que Coca Cola, Bank of America, ou encore American Express. Ces très grands groupes sur lesquels Warren Buffet est monté au capital avec des prix d’achats intéressants à l’époque de leur acquisition sont toujours en portefeuille à ce jour.
Inutile de rappeler que la stratégie de Warren Buffet est bien loin de ressembler à une stratégie de trading.
C’est donc plutôt la conviction et la confiance dans ses investissements qui animent et passionnent le célèbre multimilliardaire Oracle d’Omaha.
Pour finir, on notera une position très conséquente : plus de 22 % du portefeuille de Warren Buffet est composé d’actions Apple. Mais cette position considérable a été acquise pour un prix de revient très intéressant car inférieur à 30 $ en 2016 et un prix moyen de moins de 40 $ au fil du temps. Une certaine prise de risque bien calculée ou un petit peu chanceuse ?
Quel avenir pour Berkshire Hathaway après le départ en retraite de Warren Buffett ?
Comme annoncé, Warren Buffett a officiellement quitté ses fonctions exécutives le 1er janvier 2026, tout en conservant un rôle de président du conseil d’administration. À 95 ans, l’ancien dirigeant de Berkshire Hathaway a passé le relais opérationnel à Greg Abel, désormais CEO du groupe.
Si Warren Buffett avait évoqué dès 2025 les effets naturels du vieillissement pour justifier cette décision, il reste néanmoins présent en arrière-plan. Il continue de suivre de près les grandes orientations stratégiques et conserve un droit de regard sur les décisions majeures d’allocation du capital, notamment en période de turbulence de marché. Son retrait s’inscrit donc davantage dans une logique d’organisation et d’anticipation que dans une rupture brutale.
Pour Berkshire Hathaway, cette passation de pouvoir confirme une stratégie de continuité soigneusement préparée depuis plusieurs années. Greg Abel incarne une gestion plus opérationnelle au quotidien, tout en s’inscrivant dans l’héritage culturel du groupe. Sur le plan financier, la holding Berkshire Hathaway demeure extrêmement solide, avec une trésorerie toujours très abondante (proche des records historiques) offrant une importante capacité de déploiement en cas d’opportunités.
L’enjeu central en 2026 reste donc la préservation de la discipline d’investissement long terme chère à Buffett, tout en laissant à Greg Abel la pleine latitude managériale sur un conglomérat fondé sur l’autonomie de ses filiales.
