- IDEA 1 OF 8
Gather information through scuttlebutt
Fisher describes the scuttlebutt method, learning about a company by talking to customers, suppliers, competitors and former employees.
This gossip, carefully collected, can reveal more than official reports. Legwork beats rumours.
- IDEA 2 OF 8
Look for long-term growth potential
Fisher argues that the best investments are companies with products or markets that can grow sales for many years.
He favours businesses that keep developing new products as old ones mature.
- IDEA 3 OF 8
Fifteen points guide the search
Fisher sets out fifteen questions to judge a company, covering sales growth, profit margins, research, management and labour relations.
Few companies pass every test, but the list sharpens judgement. It remains widely studied.
- IDEA 4 OF 8
Research must lead to sales
Fisher values companies that invest in research and development, but only if it turns into useful products.
He stresses the link between research, sales effort and profits. Innovation alone is not enough.
- IDEA 5 OF 8
Management integrity is essential
Fisher argues that investors must trust management's honesty and openness, especially in bad times.
Managers who communicate frankly about problems are more likely to protect shareholders. Candour is a good sign.
- IDEA 6 OF 8
Sell rarely, and for good reasons
Fisher suggests selling only when the original judgement was wrong, the company no longer meets his tests, or a much better opportunity appears.
He warns against selling just because a price has risen.
- IDEA 7 OF 8
Too much diversification dilutes results
Fisher argues that owning too many companies means owning many that are not well understood.
He prefers knowing a smaller number of outstanding businesses very well. Depth beats breadth for him.
- IDEA 8 OF 8
Avoid common investor mistakes
Fisher lists mistakes such as obsessing over small price differences or following the crowd.
He presents his ideas as a philosophy for careful long-term ownership, not quick gains. Patience is central.
