Philip Fisher's 15 Points: A UK Investor's Checklist

Philip Fisher's 15 points are the qualitative checklist he laid out in his 1958 book Common Stocks and Uncommon Profits for separating excellent growth companies from average ones. Warren Buffett has said he is "85% Graham and 15% Fisher", and the Fisher 15% is the bit that pushed him from buying cheap cigar butts to buying great businesses. This guide walks each of the 15 points and shows where a UK investor actually finds the answers in 2026.

What the 15 points are for

Fisher was a growth investor. He wanted to find companies he could hold for fifteen, twenty, thirty years and let compound on themselves. He held Motorola for over four decades. The 15 points are the screen he ran on every candidate before he was willing to put real money in. Pass the screen and you might have an investable business. Fail two or three points and you walk away, regardless of price.

The list is qualitative, not quantitative. You will not find a P/E ratio or a debt-to-equity threshold in it. That is intentional. Fisher's view was that ratios tell you what a company has done; the 15 points tell you whether it will keep doing it. For the quantitative side, our guide on how to value a stock for UK investors covers the ratios that pair naturally with this framework.

The scuttlebutt method

Fisher's word for the research technique behind the 15 points was scuttlebutt: navy slang for the rumours you pick up around the water cooler. The method is to talk to people who deal with the company in real life. Customers. Suppliers. Ex-employees. Competitors, especially competitors, because rivals will tell you what a CEO never will. Five honest scuttlebutt conversations beat a hundred pages of broker research.

For a UK investor in 2026 that translates to LinkedIn outreach, Glassdoor and Indeed reviews, Reddit threads in industry-specific subs, AGM transcripts (most FTSE 100 companies publish them), and trade press. The Investors' Chronicle and Citywire cover UK names in more depth than the Bloomberg headline machine. If you used to work in a sector, that is your edge - use it before you read another set of accounts.

The 15 points, one by one

1. Does the company have products or services with enough market potential for sales growth for years?

The first filter is runway. A company selling something that will be saturated in three years is not a Fisher stock. Read the strategic report at the front of the annual report; UK firms have to publish one under the Companies Act 2006. Look for total addressable market language backed by actual figures, not vibes.

2. Is management determined to keep developing products that will keep growing sales when current lines mature?

Today's product peaks. The question is whether management is already funding tomorrow's. Capital allocation discussion in the annual report and Capital Markets Day decks tell you a lot. Beware companies that cling to a single cash cow.

3. How effective are the company's research and development efforts relative to its size?

R&D spend as a percentage of revenue is the starting number; the actual question is what they get for it. Patent filings, new product launches over the past five years, and gross margin trajectory on newer lines are better signals than the headline spend.

4. Does the company have an above-average sales organisation?

The best product in the world dies on a bad sales floor. Look at revenue per salesperson if it is disclosed, customer concentration (a top-10 customers note hiding in the accounts), and Glassdoor reviews from sales staff specifically. UK B2B firms often disclose less than US peers, so ex-employee chatter matters more here.

5. Does the company have a worthwhile profit margin?

Fisher wanted margins comfortably above industry average. Pull operating margin from the income statement and compare to two or three direct peers. A FTSE 250 retailer at 4% margin in an industry averaging 7% is a different conversation than the same company at 10%.

6. What is the company doing to maintain or improve profit margins?

A high margin today is no use if it is being competed away. Read the operational efficiency section of the strategic report. Automation, vertical integration, pricing power, and supplier renegotiation are the typical levers. If management is silent on margin defence, assume it is not happening.

7. Does the company have outstanding labour and personnel relations?

Strikes, high turnover, and grievance cases all surface in qualitative pages of the annual report under workforce engagement, but the unvarnished version is on Glassdoor. Look at the trend in employee reviews over three years, not the headline star rating. A UK firm with employee Trustpilot-style reviews collapsing from 4.2 to 3.4 is telling you something accounts will not.

8. Does the company have outstanding executive relations?

This is the level above the shop floor: how the C-suite treats senior managers. Frequent turnover in the layer below CEO is a giveaway. RNS announcements track every director and PDMR change on a UK-listed firm - search the company's RNS history on the London Stock Exchange website for a five-year view.

9. Does the company have depth to its management?

A one-genius company is a fragile company. Look at the executive bios in the annual report, internal promotion rates, and how long the C-suite has been with the business. A company where the CFO came from finance director three years earlier is healthier than one that hires every senior role externally.

10. How good are the company's cost analysis and accounting controls?

Goodwill write-downs, restated accounts, frequent change of auditor, and lengthy "alternative performance measures" sections are the red flags. The FCA-regulated big-four audit report and the audit committee report in the annual filing are the place to look. A clean audit opinion is necessary but not sufficient; read the key audit matters.

11. Are there industry-specific aspects that give the company a competitive edge?

Fisher made this point deliberately vague because every industry has its own moat shape. Regulatory licensing in financial services. Patent estate in pharma. Network effects in payments. Brand strength in consumer staples. Identify the one or two unfair advantages in the specific industry, then check whether your candidate has them. Our piece on writing your investment thesis gets at the same idea from a different angle.

12. Does the company have a short-range or long-range outlook on profits?

Earnings management is the warning sign here. A company that hits its quarterly number to the penny for eight straight quarters is probably steering. A company that takes a hit in a soft quarter to invest in a five-year project is the kind Fisher liked. Read three years of CEO letters to shareholders back to back - the framing tells you which camp they are in.

13. Will future growth require equity financing that dilutes existing shareholders?

Growth funded by debt or retained earnings benefits you. Growth funded by issuing new shares dilutes you. Check the share-count history over five years in the company's annual reports or on Stockopedia. A steadily rising share count is a tax on every existing holder.

14. Does management talk freely about its affairs when things are going well and clammed up when problems arise?

The CEO letter in a bad year is the single most useful document on the file. Pull the annual report from the worst recent year and read how management explained the problem. Honest, specific, with a plan? Pass. Bland, defensive, full of "challenging market conditions"? Fail.

15. Does the company have a management of unquestionable integrity?

Fisher was clear that this point is the only one with a binary outcome: any doubt and you walk. Check the FCA enforcement notices register, look at related-party transactions in the accounts, scan the chair's pay against company performance, and listen for ex-employees describing a culture of "creative" reporting. One serious integrity flag invalidates the other fourteen passes.

Applying the checklist as a UK investor

Fisher wrote for an American audience holding US growth stocks in the 1950s. The framework still works in the UK, but a few specifics translate differently.

1. The free toolkit is genuinely good. Annual reports on investor relations pages, RNS announcements via the LSE, Companies House filings, Glassdoor, and the FCA register cover most of what Fisher had to chase by phone. You do not need a Bloomberg terminal.
2. Smaller market, faster scuttlebutt. UK industries are tightly networked. A few well-chosen LinkedIn messages to mid-level managers at a target company's competitors will return answers a US investor cannot get as easily. Use it.
3. The integrity point matters more in growth-stock land. UK fraud cases like Patisserie Valerie and NMC Health both passed casual screens. Sceptical reading of the accounting policies section pays.
4. Pair this with quantitative discipline. The 15 points get you a great business. Whether it is a great investment also depends on price. Run Fisher's screen first, then check the P/E ratio and broader valuation work before buying.

Frequently Asked Questions

What are Philip Fisher's 15 points in summary?

The 15 points are a qualitative checklist for evaluating growth stocks: market runway, product pipeline, R&D effectiveness, sales organisation, profit margins, margin defence, labour relations, executive relations, management depth, accounting controls, industry-specific advantages, long-range outlook, anticipated equity dilution, candour with shareholders, and management integrity. A company has to pass most of them to be investable.

What is the scuttlebutt method?

The scuttlebutt method is Fisher's research technique of gathering first-hand information from a company's customers, suppliers, ex-employees, and competitors. It is the qualitative work that backs up the 15 points - the things annual reports cannot tell you. In 2026 a UK investor runs it through LinkedIn, Glassdoor, industry forums, and trade press rather than the phone calls Fisher used.

Are Fisher's 15 points still relevant in 2026?

Yes. The specific examples in the book are dated, but the underlying questions about product runway, management quality, margins, and integrity are the same ones any growth investor still needs to answer. Buffett continues to cite Fisher's influence on Berkshire Hathaway's investment process.

How does Fisher's approach differ from Benjamin Graham's?

Graham focused on buying statistically cheap companies, with margin of safety priced in upfront. Fisher focused on buying excellent companies and holding them through any reasonable price, on the view that compounding does the heavy lifting. Buffett famously blends both: Graham's discipline on price with Fisher's eye for quality.

Can a UK retail investor realistically apply the 15 points?

Mechanically, yes - the source material is mostly free and in English. Honestly, the framework is most useful when you have a structural information advantage in a specific industry. Without one, you risk confusing thorough reading with genuine insight. For most UK investors the safer translation is to hold a global tracker and apply Fisher's patience principle to that, rather than running a concentrated Fisher portfolio.
