Philip Fisher / The Growth Stock Pioneer Who Bought and Almost Never Sold

While investors of his era hunted for cheap stocks in financial statements, Fisher talked to a company’s customers, competitors and suppliers to find businesses that could grow for decades, then held them as long as possible. His 1958 book became a text Buffett praises. On this page you can check a company with the 15-point list, go out and gather information Scuttlebutt-style, and see what selling too early costs.

From the 1929 crash to MotorolaFrom analyst in a crisis year to half a century of holding growth stocks

Fisher started working in the market just over a year before the 1929 crash and founded his own firm during the Depression. He chose a different path from most investors of the era, looking for companies that could keep growing for a long time instead of stocks priced below their assets

He managed money for a small group of clients in San Francisco for almost 70 years. Tap each stage to follow the journey

The 15 pointsLab: check a company with Fisher’s 15-point list

In Common Stocks and Uncommon Profits, Fisher gives 15 questions for checking whether a company is outstanding enough to hold long term. He writes that a company failing just a few points may still be a good investment, but if management isn’t honest, it shouldn’t be bought however good the other points are. Choose a hypothetical company, or tap each point to switch between Pass · Fail · Unknown

What it means for traders

Traders can have a pre-entry checklist too: which way the big trend is going, whether major news is close, where the stop loss is. If the most important point fails, such as not knowing where you’ll exit, don’t enter however good the other points are

ScuttlebuttGame: go gather information from the people around a company

Fisher called gathering information from people around a company Scuttlebutt. He talked to customers, competitors, suppliers, former employees and experts, because each sees the company from an angle the financial statements don’t show, and he advised meeting management only after gathering a well-rounded picture. You have time to interview 4 of 6 people, then decide whether to buy

Time left 4 / 4 interviews
Interview at least 3 people before deciding

Choose who to talk to. Tap a card to hear what they say

The companies, interview information and outcomes are all hypothetical, written following the method Fisher describes in his book. In real life, beware of non-public inside information, which is illegal to trade on

What it means for traders

Rumours in a chat group aren’t Scuttlebutt. What Fisher did was compare several sources that see the company from different angles. Traders can do the same, for example checking whether inflation, employment and central bank tone point the same way or conflict before believing any single analysis

05

The time to sell is almost neverLab: sell early, hold forever, or sell when the reason changes

Fisher saw many investors sell good stocks because the price had already risen a lot, then miss decades of growth that followed. But he didn’t say to hold everything forever. Compare 4 approaches for a hypothetical company over 40 years: hold forever, sell at a profit target, sell when growth stops, and buy the whole market

Hold forever (after tax)—
Sell at target—
Sell when growth stops—
Buy the market—

Hypothetical company model: price = earnings per share × P/E, starting at a P/E of 25. When growth stops, earnings grow just 3% a year and the P/E falls to 12 within 3 years. No dividends. Money from selling moves into the whole market, returning 8% a year. The sell-when-growth-stops approach notices 1 year late. The lines show value before tax, while the figures at the end of the lines and in the boxes are multiples of the original money after paying tax on selling everything in year 40. Fees excluded, and in reality nobody knows in advance how long a company will keep growing

1973 · as told by Ken Fisher6 stocksStocks making up about 2/3 of his assets
Reasons to sell3 reasonsNone is about the price rising
Fisher & Co.68 years1931–1999
What it means for traders

Many traders close winning trades early but let losing trades run, the opposite of what Fisher taught. Define what signals that the reason behind a trend has changed, and hold until you see that signal, instead of closing because profit hit a round number

06

Three reasons to sellGame: sell or hold, by Fisher’s 3 reasons

Fisher accepted just 3 reasons to sell: discovering you bought wrongly in the first place, the company no longer meeting the original criteria, and finding a clearly better opportunity. A big price rise or fear that the market will fall aren’t on the list. In each situation, choose what to do

Score 0 / 6
Situation 1

Bought 1 year ago, the stock is up 80%. Sales and new products are still going exactly to plan

Situation 2

Shortly after buying, you discover management hid a big product problem and gave information that doesn’t match reality

Situation 3

The whole stock market falls about 25% on fears of recession, but the company is still selling well and has enough cash

Situation 4

The main product is maturing, a new management team cuts the research budget, and there are no new products planned at all

Situation 5

You find another company you’ve studied deeply that clearly meets the criteria better than your current one, and you’re very confident in the information

Situation 6

This quarter’s profit fell 30% because the company started a new production line, with high start-up costs announced in advance

Tap an answer on each card

We wrote these situations for learning, based on the 3 reasons to sell in Common Stocks and Uncommon Profits. The explanations are paraphrased, not Fisher’s own words

07

Fact checkFact check: truth and stories passed along

Fisher rarely appeared in the media and managed money for private clients, so his story has been retold until some parts are inaccurate. We sort each one by the weight of the evidence

1955Supported

Fisher bought Motorola in 1955 and held it until his death

Wikipedia and a Motley Fool article agree he bought in 1955 and never sold, but some websites give a different purchase year. Late in life, his son says, he was ill and couldn’t make investment decisions as well as before

1969Supported

Buffett said he is 85% Graham and 15% Fisher

The line is widely quoted, including on Wikipedia, and usually said to come from Forbes in 1969. Buffett has also praised Fisher’s book on many occasions. The split is a figure of speech, not a measurable number

1958Supported

Scuttlebutt is the method Fisher made famous

Common Stocks and Uncommon Profits describes gathering information from customers, competitors, suppliers, former employees and experts before meeting management, and the term has been tied to his name ever since

1958Partly true

Fisher taught that you should never sell stocks

He wrote that if you bought the right stock, the time to sell is almost never, but he also gave 3 reasons to sell: buying wrongly in the first place, the company no longer meeting the criteria, and finding a clearly better opportunity

—Partly true

Fisher held only a few stocks

A summary of his ideas in The Motley Fool says holding over 20 is a sign you don’t understand what you hold, and 10–12 is usually better. Ken Fisher says that in 1973, 6 stocks made up about 2/3 of his assets, but some sources say he held about 30, so the number varies with the period

1961–62Partly true

Fisher was an investing professor at Stanford

Ken Fisher says his father taught a graduate investing course temporarily for about 2 years while the regular professor was on leave. He wasn’t a permanent professor, and he never finished his own graduate degree there

—Common misconceptions

Fisher ignored price and would buy at any level

He warned against waiting for a slightly lower price and missing a great stock, but he also wrote about timing purchases, such as buying when a good company has a temporary problem, and warned that buying what the crowd loves is risky

—Common misconceptions

Fisher has a verifiable record of beating the market by a certain percentage a year

He managed money for private clients through Fisher & Co., not a mutual fund that must disclose performance. We found no verifiable career return figure. Figures seen online are usually estimates

1979Common misconceptions

Ken Fisher took over Fisher & Co. from his father

Ken Fisher founded his own firm, Fisher Investments, in 1979, while his father’s Fisher & Co. operated until his father retired in 1999. The two firms are separate

LessonsLessons for Forex and gold traders

Your checklist
0/4
01

Hear several sources before believing

Fisher didn’t just believe what management said; he compared it with customers, competitors and suppliers. Traders can use the same principle: news or analysis from one source isn’t enough, so check real economic data too

02

Let trades going the right way run

Selling because the profit is already big is what Fisher said makes investors miss large returns. For traders, instead of closing early out of fear of losing profit, try trailing your stop loss behind the price

03

Exit when the reason changes

Fisher’s reasons to sell are about the company, not the price. Traders should write down their reason for entering first, and exit when that reason no longer holds, for example when a central bank changes its tone

04

Know a few deeply

Fisher liked holding a few stocks he truly knew. Traders who open many currency pairs at once often carry overlapping risk without realising. Choose a few markets you understand and control the order size of each

Let winners run.Hold the right trades, exit when the reason changes

What you can apply from Fisher is gathering information from several sources, holding what’s going the right way for a long time, and exiting when the reason changes, not when the price excites or scares you. Here are tools on 1TRADER that can help
