Philip Fisher and Fisher & Co

Philip Arthur Fisher was an American investor and the founder of Fisher and Company, a San Francisco-based investment counseling firm he established in 1931 and ran until his retirement in 1999 at age 91. He is widely regarded as the father of growth investing, a methodology focused on identifying exceptional companies with durable competitive advantages and holding them for the long term. Warren Buffett has described his own investment philosophy as 85% Benjamin Graham and 15% Philip Fisher.

Think of Fisher's approach like an expert hiring manager: he cared far more about character, culture, and potential than about today's balance sheet numbers.

From Stanford to San Francisco: Fisher's Early Career

Fisher dropped out of Stanford Graduate School of Business in 1928, before completing his degree, to work as a securities analyst at the Anglo-London Bank in San Francisco. He later returned to Stanford as one of only three people ever to teach its investment course. He founded Fisher and Company in 1931, during the depths of the Great Depression, and built it into a respected firm by quietly earning extraordinary returns for a small, carefully selected group of clients.

He remained largely unknown to the public until he published his landmark book, Common Stocks and Uncommon Profits, in 1958. The book became an immediate bestseller and secured his place in investment history.

The Scuttlebutt Method

Fisher's most distinctive research technique was what he called the scuttlebutt method. Rather than relying solely on financial statements, he gathered information by speaking directly with people who knew the company: competitors, suppliers, customers, former employees, and industry executives. He believed that by talking to enough people who interacted with a business, the quality and trajectory of that business would become obvious to any experienced observer.

This approach was revolutionary in the 1950s. Most analysts at the time relied almost entirely on published financial data. Fisher argued that the most important information about a company's future was not yet in its financial statements.

The Fifteen Points: Fisher's Qualitative Framework

Fisher's most enduring contribution was his list of fifteen qualitative factors to evaluate before purchasing a stock. The framework prioritized the quality of the business and its management over current valuations. Key criteria from the fifteen points include:

• Does the company have products or services with sufficient market potential to make possible a sizable increase in sales for at least several years?
• Does management have a determination to continue to develop products or processes that will still further increase total sales potential when the growth potential of current lines has been largely exploited?
• How effective are the company's research and development efforts relative to its size?
• Does the company have an outstanding sales organization?
• Does the company have a worthwhile profit margin?
• Is management open with investors about operations when things go wrong as well as when they go right?
• Does the company have unquestionable management integrity?

Fisher stated that if a company failed on the integrity point, he would never consider the stock regardless of how well it scored on every other criterion.

The Motorola Investment: 44 Years of Compounding

Fisher's most famous investment was Motorola. He purchased shares in 1955 when the company was primarily a radio manufacturer. He held the position until his death in 2004 at age 96, a holding period of 44 years. His gains on Motorola over that period were extraordinary and validated his core thesis: exceptional companies held through business cycles and technological transitions produce returns that short-term trading cannot replicate.

Fisher's approach to selling was as distinctive as his approach to buying. In Common Stocks and Uncommon Profits, he argued that the best time to sell a stock was "almost never," meaning only when a company's fundamental character had genuinely changed for the worse, not simply because the price had risen or market conditions had shifted.

Fisher's Influence on Warren Buffett and Modern Investing

Buffett sought out Fisher after reading Common Stocks and Uncommon Profits and later said the meeting impressed him as much as the book did. Fisher's influence pushed Buffett beyond Graham's pure quantitative focus on undervalued balance sheets toward a willingness to pay a fair price for an exceptional business. Buffett's investment in Coca-Cola in 1988 at a price-to-earnings ratio that would have been anathema to Graham reflects Fisher's influence in practice.

Fisher's son Kenneth Fisher became a prominent investor and Forbes columnist in his own right and has extended his father's work through numerous books and the Fisher Investments money management firm, which manages over $250 billion in client assets as of 2025.
