Warren Buffett’s investment career started in earnest in 1957, with the formation of his first investment partnership. Following two years of working as a securities analyst at the Graham-Newman Corporation and the well-documented experience of studying at the Columbia Business School under Benjamin Graham, Buffett established Buffett Partnership Limited (BPL) with the funding of a few friends, family, and close associates.1
While details of Buffett’s investment thought process are much more widely documented later in his career, a few obvious themes can be discerned in his partnership years. Foremost is the focus on being a buyer at a good price. In his 1962 partnership letter, Buffett states that the cornerstone of his investment philosophy is to purchase assets at a bargain price, which he considers in the traditional Benjamin Graham view of low price versus intrinsic valuation—a fundamental assessment of a company’s ability to generate cash flow or a company’s value in assets. Second, Buffett adopts a strong view of a moving market; Mr. Market either overvalues or undervalues a company, but over the long run does pass around the intrinsic value. Third, Buffett also pays attention to investor psychology as pertains to who is investing in the market and what impact this investor thinking has. Specifically, he mentions several times the concept of whether investors have steady hands and the manias of different periods.
In running his partnership, Buffett kept secret his holdings during this period and adopted a black-box type of strategy with his limited partners. In the appendix of his 1963 year-end partnership letter he states, “We cannot talk about our current investment operations. Such an open-mouth policy could never improve our results and in some situations could seriously hurt us. For this reason, should anyone, including partners, ask us whether we are interested in any security, we must plead the Fifth Amendment.”
The significant investments Buffett made during this time were a mix of value bets and corporate actions. At times BPL would invest up to 35 percent of its net assets into a single company and at times, given the opportunity, take a majority ownership stake in the company.
When Buffett ran his partnership during the late 1950s and 1960s, the United States was enjoying relatively calm and economically prosperous times: on the heels of the Korean War in the 1950s and in the midst of the Cold War at the beginning of the 1960s, the U.S. economy was less eventful than its politics. In the 1950s the Dow climbed from approximately 200 points in 1950 to roughly 600 points in 1960 (a 200 percent increase). Although there was a small recession at the beginning of the 1960s that saw the Dow pull back into the 530s in 1962 from a high in the 730s at the end of 1961 (a decrease of 27 percent), the Dow would rise again to over 900 by 1965 (a 70 percent increase from the low). The economy continued to grow through the Kennedy years, with signs of the first serious concerns only surfacing at the end of the 1960s when inflation rates started increasing ever more quickly. By the time Buffett closed his investment partnership in 1968, economic prosperity abounded to a level where he found it increasingly difficult to find the value investments that he was looking for. This was in fact one of the key rationales for ending his partnership amidst great performance.
