Warren Buffett may have been born with business in his blood. He purchased his first stock when he was 11 years old and worked in his family’s grocery store in Omaha. His father, Howard Buffett, owned a small brokerage, and Warren would spend his days watching what investors were doing and listening to what they said. As a teenager, he took odd jobs, from washing cars to delivering newspapers, using his savings to purchase several pinball machines that he placed in local businesses.
His entrepreneurial successes as a youth did not immediately translate into a desire to attend college. His father pressed him to continue his education, with Buffett reluctantly agreeing to attend the University of Pennsylvania. He then transferred to the University of Nebraska, where he graduated with a degree in business in three years.
After being rejected by the Harvard Business School, he enrolled in graduate studies at Columbia Business School. While there, he studied under Benjamin Graham – who became a lifelong friend – and David Dodd, both well-known securities analysts. It was through Graham’s class in securities analysis that Buffett learned the fundamentals of value investing. He once stated in an interview that Graham’s book, The Intelligent Investor, had changed his life and set him on the path of professional analysis to the investment markets. Along with Security Analysis, co-written by Graham and Dodd it provided him the proper intellectual framework and a road map for investing.
Benjamin Graham and The Intelligent Investor
Graham is often called the “Dean of Wall Street” and the father of value investing. One of the most important early proponents of financial security analysis, Graham was so influential that he helped draft the Securities Act of 1933. He championed the idea that the investor should look at the market as though it were an actual entity and potential business partner – Graham called this entity “Mr. Market” – that sometimes asks for too much or too little money to be bought out.
It would be difficult to summarize all of Graham’s theories in full. At its core, value investing is about identifying stocks that have been undervalued by the majority of stock market participants. He believed that stock prices were frequently wrong due to irrational and excessive price fluctuations (both upside and downside). Intelligent investors, said Graham, need to be firm in their principles and not follow the crowd.
Graham wrote The Intelligent Investor in 1949 as a guide for the common investor. The book championed the idea of buying low-risk securities in a highly diversified, mathematical way. Graham favored fundamental analysis, capitalizing on the difference between a stock’s purchase price and its intrinsic value.
Entering the Investment Field
The Buffett that modern investors admire almost wasn’t. When he graduated from Columbia he intended to work on Wall Street, but Graham convinced him to make another career choice. Heading back to Omaha, Buffett worked as a stockbroker and created several investing partnerships. The size of the partnerships grew substantially, and by the time he was 31 he was a millionaire.
It was at this point – in 1961 – that Buffett’s sights turned to directly investing in businesses. He made a $1 million investment in a windmill manufacturing company, and the next year in a bottling company. Buffett used the value-investing techniques he learned in school, as well as his knack for understanding the general business environment, to find bargain…
