We just published a list of the 10 Best Stocks To Buy According to Billionaire Armitage and Medline (NASDAQ:MDLN) ranked 8th on this list.
John Armitage has managed money since the early 1980s, and the record behind his firm is the reason investors keep an eye on his filings. He started Egerton Capital in London in 1994 with William Bollinger, after a career at Morgan Grenfell that began in 1981. There he ran a unit trust for six years that beat its index by 10% a year and ranked first among 85 funds, which gave him the confidence to go alone.
Egerton runs a concentrated, long-biased book. Its third-quarter 13F lists 23 holdings worth $9.82 billion, and the five largest account for 52.4% of that total.

Pricing Power, Realistic Managers and Valuation Discipline
Armitage laid out his philosophy in a podcast hosted by Nicolai Tangen, who worked for him for five years before running Norges Bank Investment Management. His first question about any idea is whether it is worth the time, since many businesses are fairly priced, and the second is whether he can understand it.
He prizes pricing power, the ability to raise prices despite competition, because a company that outpaces its own cost inflation achieves structurally rising margins. He also watches incremental margins, since a high margin on extra sales can swing profit sharply when revenue beats or misses. The balance sheet gets the same attention as the income statement, from inventories to receivables.
He wants managers who admit their mistakes and distrusts those who always present a rosy picture or lean on accounting choices to look better. Valuation matters to him, perhaps too much, he admits, because it has made him miss many great growth stocks. He dismisses enterprise value to EBITDA as meaningless because depreciation is a real cost.

Recent Returns Lag the Market, but the Long Record Holds Up
He builds positions slowly, starting small and adding as conviction grows, and he usually trims after a disappointment because he prefers confirmation of a thesis to contradiction. At the firm, two people must love an idea before it becomes large, and he prefers thematic diversification to heavy concentration.
