The Beginnings of an Investing Career
Warren Buffett’s foray into the world of investment began at a remarkably young age, igniting a passion that would eventually propel him to the zenith of financial success. Born in Omaha, Nebraska, Buffett displayed a fascination with business and investing early on. As a teenager, he seized opportunities by selling goods such as Coca-Cola and magazine subscriptions, alongside dabbling in the stock market, which laid the groundwork for his future endeavors. In 1947, he enrolled at the University of Nebraska, where he honed his analytical skills and developed a keen interest in economics and finance.
Warren Buffett’s significant break came when he was accepted into Columbia Business School, where he studied under the esteemed Benjamin Graham. This pivotal relationship had a profound impact on Buffett’s investing philosophy. Graham, often referred to as the father of value investing, emphasized the importance of thorough research, a margin of safety, and the need for a long-term perspective. After completing his education, Buffett took a position at Graham-Newman Corp. in New York, gaining invaluable experience that shaped his understanding of market dynamics and investment strategies.
During his tenure at Graham-Newman, Warren Buffett encountered real-world challenges and began formulating his approach to investing. The principles he learned from Graham reinforced the importance of investing in undervalued companies with solid fundamentals, a strategy that would later become a hallmark of Buffett’s legendary career. Following this period, he established his first investment partnerships, pooling capital from family and friends. These partnerships not only allowed him to practice and refine his investment techniques but also fostered an environment of learning and adaptation. Each investment provided critical lessons, shaping the investor he would ultimately become.

The Formation of Berkshire Hathaway
Berkshire Hathaway’s transformation from a failing textile company into a global powerhouse under Warren Buffett’s leadership exemplifies the power of disciplined, long-term investing. With a market capitalization exceeding $900 billion, $328 billion in cash reserves, and a diverse portfolio spanning insurance, transportation, energy, and major equity stakes in companies like Apple and Coca-Cola, Berkshire’s financial strength is unmatched.
Background of Berkshire Hathaway
Berkshire Hathaway, headquartered in Omaha, Nebraska, began as a textile manufacturing company formed by the merger of Berkshire Cotton Manufacturing (1889) and Hathaway Manufacturing (1888) in 1955. Struggling by the early 1960s, it caught the attention of Warren Buffett, who, through Buffett Partnership Limited, started acquiring shares in 1962 at $7.50 each, taking control in 1965.
Buffett shifted the company’s focus from textiles, which were fully shuttered by 1985, to a diversified holding company. Under his leadership, alongside vice chairman Charlie Munger (until Munger died in 2023), Berkshire evolved into a global conglomerate with subsidiaries in insurance, transportation, energy, manufacturing, retail, and services, as well as significant investments in public companies like Apple, Coca-Cola, and Bank of America.
Buffett’s value investing philosophy—focusing on undervalued companies with strong fundamentals and long-term potential—transformed Berkshire into one of the world’s largest and most respected corporations. As of 2025, Greg Abel, CEO of Berkshire Hathaway Energy, is set to succeed Buffett as CEO by year-end.
Financial Strength of Berkshire Hathaway
Berkshire Hathaway’s financial strength is formidable, driven by its diversified revenue streams, massive cash reserves, and strategic investment approach. As of March 31, 2025, the company held $328 billion in cash, cash equivalents, and short-term investments in U.S. Treasury bills, reflecting its liquidity and ability to seize opportunities.
Its market capitalization exceeds $900 billion, making it one of the largest publicly traded companies globally, with Class A shares trading at over $800,000 each, the highest-valued stock in the U.S. Insurance subsidiaries like GEICO and Berkshire Hathaway Reinsurance Group generate significant revenue and “float” (premiums held before claims), which Buffett reinvests into acquisitions and equities.
In Q1 2025, Berkshire reported $89.725 billion in revenue, though net earnings fell to $4.672 billion due to $6.435 billion in unrealized investment losses. Key subsidiaries, including BNSF Railway, Berkshire Hathaway Energy, and wholly owned businesses like Duracell and Dairy Queen, contribute robust earnings before taxes ($5.148 billion in Q1 2025). Berkshire’s equity portfolio, valued at over $346 billion as of December 2022, includes major stakes in Apple (26% of the portfolio), American Express, and Coca-Cola.
Despite occasional losses, such as a $12.8 billion net loss in Q3 2023 from an 11.7% drop in Apple’s stock, Berkshire’s long-term performance has outpaced the S&P 500, delivering exceptional returns for shareholders. Its debt-free balance sheet and low-cost capital from insurance float provide a competitive edge, enabling large-scale acquisitions like BNSF ($26 billion in 2010) and Pilot Travel Centers (100% ownership in 2024).

Top 10 Investment Strategies to Increase Wealth
Warren Buffett, one of history’s most successful investors, has built his wealth through disciplined, value-driven strategies. Below are his top 10 investment strategies to increase wealth, drawn from his letters, interviews, and documented approaches, tailored as a guide for investors:
01. Stay Within Your Circle of Competence
Warren Buffett stresses the importance of investing only in businesses or industries you deeply understand. This “circle of competence” allows you to evaluate a company’s long-term potential with confidence. For instance, Buffett largely avoids tech companies like Tesla or emerging AI firms because their future dynamics are outside his expertise.
Instead, he focuses on familiar sectors like consumer goods (e.g., Coca-Cola) or insurance (e.g., GEICO). For individual investors, this means researching industries you know—whether retail, real estate, or healthcare—before committing capital. Start by studying annual reports or industry trends to define your circle.
02. Embrace Value Investing
Rooted in Benjamin Graham’s philosophy, Buffett’s value investing approach involves buying companies trading below their intrinsic value—essentially getting a dollar’s worth of business for 50 cents. He seeks firms with strong fundamentals, such as consistent earnings, low debt, and growth potential.
For example, his 1988 investment in Coca-Cola capitalized on its undervalued stock price and enduring brand strength. Investors can apply this by using metrics like price-to-earnings (P/E) ratios or discounted cash flow (DCF) models to identify bargains, ensuring a margin of safety against market volatility.
03. Commit to Long-Term Ownership
Warren Buffett’s mantra, “If you aren’t willing to own a stock for 10 years, don’t even think about owning it for 10 minutes,” highlights his long-term perspective. He views stocks as ownership in businesses, not speculative assets. His decades-long holdings in American Express and Coca-Cola demonstrate how compounding drives wealth.
For retail investors, this means resisting the urge to trade frequently and focusing on companies with durable prospects. Dollar-cost averaging into quality stocks or index funds can align with this strategy, minimizing the impact of short-term market swings.
04. Seek Companies with Economic Moats
An “economic moat” is a sustainable competitive advantage that protects a company from rivals. Buffett invests in businesses with strong brand loyalty (e.g., Apple), unique market positions (e.g., BNSF Railway), or cost advantages (e.g., Walmart). These moats ensure long-term profitability and resilience.
For example, Apple’s ecosystem and brand loyalty create barriers to competition, justifying Buffett’s massive stake. Investors should look for companies with patents, exclusive contracts, or unmatched scale, which can be identified through competitive analysis or industry reports.
05. Demand a Margin of Safety
To reduce risk, Buffett buys stocks at a significant discount to their intrinsic value, providing a buffer against errors or market downturns. This margin of safety protects against unforeseen challenges, like economic recessions or management missteps. For instance, his 2008 investment in Goldman Sachs during the financial crisis capitalized on a discounted price with favorable terms. Investors can calculate intrinsic value using DCF or compare a stock’s price to its book value, ensuring purchases are made at a discount to estimated worth.
06. Prioritize Quality Management
Warren Buffett places immense value on competent, ethical management teams that act as stewards of shareholder capital. He seeks leaders who allocate profits wisely—through reinvestment, dividends, or share buybacks—while avoiding reckless expansion. His trust in Apple’s Tim Cook, who balances innovation with shareholder returns, exemplifies this. Investors can evaluate management by reviewing CEO letters, track records, and capital allocation decisions in annual reports. Avoid companies with frequent leadership turnover or questionable ethics.
07. Calculate Intrinsic Value
Warren Buffett assesses a company’s worth based on its future cash flows, discounted to the present, rather than relying on market sentiment or short-term price movements. This intrinsic value focus guided his investments in companies like See’s Candies, which generated steady cash flows. For individual investors, learning basic DCF analysis or studying Buffett’s shareholder letters can demystify this process. Tools like financial calculators or platforms like Morningstar can help estimate cash flows, keeping the focus on long-term business value.
08. Reinvest Earnings for Compounding
Warren Buffett’s wealth exploded by reinvesting profits into high-quality businesses rather than pocketing dividends. Berkshire’s insurance “float”—premiums held before claims—fuels acquisitions like Precision Castparts. For retail investors, reinvesting dividends through DRIPs (Dividend Reinvestment Plans) or maxing out contributions to tax-advantaged accounts like IRAs mimics this strategy. For example, reinvesting dividends from an S&P 500 index fund over 20 years can significantly boost returns through compounding.
09. Be Patient and Contrarian
Buffett’s contrarian approach—buying when others panic—has led to some of his best deals. During the 2008 financial crisis, he invested $5 billion in Goldman Sachs and $3 billion in General Electric at rock-bottom prices, reaping massive returns as markets recovered. Patience means waiting for the right opportunity, even if it takes years. Investors can adopt this by avoiding herd mentality, researching undervalued stocks during market dips, and holding cash reserves to act when prices are low.
10. Invest in Yourself
Buffett attributes much of his success to continuous learning, spending hours daily reading annual reports, financial statements, and industry publications. He believes improving your knowledge and decision-making skills is the ultimate investment. For example, his deep understanding of insurance dynamics fueled Berkshire’s dominance in that sector. Investors can emulate this by reading books like The Intelligent Investor, attending financial workshops, or following reputable sources like Berkshire’s shareholder letters. Education compounds wealth by sharpening your ability to spot opportunities.
These strategies, rooted in discipline, patience, and a focus on long-term value, have driven Buffett’s success. While his approach may seem simple, it requires rigorous research and emotional control. For those who prefer a hands-off approach, Buffett also recommends low-cost S&P 500 index funds as a reliable way to build wealth over time.

Challenges and Controversies
Warren Buffett, revered as one of the most successful investors of the modern era, has not been without his share of challenges and controversies throughout his career. While his investment strategies often reflect prudence, there have been instances where his decisions have raised eyebrows and sparked debate among analysts and investors alike.
A notable period of scrutiny occurred during the financial crisis of 2008-2009. Critics questioned Buffett’s investment in Goldman Sachs, which ultimately received a substantial bailout. While his initial investment was lauded, the ethical implications of capital allocation during a public financial rescue prompted discussions about the morality of profiting from systemic failures.
Furthermore, Buffett’s investment strategies sometimes led him to endorse companies and sectors that are ethically contentious. For instance, his investments in tobacco companies have drawn significant criticism from public health advocates. These investments are seen as contrary to his public persona, as he often emphasizes the importance of ethical business practices. The duality of his investment choices versus his public persona raises questions about the boundaries between profit-making and ethical responsibility.
Moreover, Buffett’s association with the hedge fund industry has elicited controversy, particularly regarding the performance fees charged by fund managers compared to his preferred “buy and hold” strategy. Critics have argued that hedge funds encourage speculative trading that could destabilize markets, thereby contrasting with Buffett’s philosophy of long-term value creation.
Despite these challenges, Buffett has remained steadfast in his approach, often citing his belief in transparency and ethical leadership as guiding principles. Ultimately, the ongoing discussions surrounding his investment choices illuminate the complex realities of navigating the dual pressures of profit and ethics in the investment landscape.
