Nicolai Tangen

Nicolai Tangen is the CEO of Norges Bank Investment Management (NBIM), which runs Norway’s sovereign wealth fund — at roughly $2 trillion the largest single fund in the world, holding stakes in some 9,000 companies and owning on the order of 1.5% of every listed company on earth. Appointed in 2020, he manages the fund against a reference index set by Norway’s Ministry of Finance, running about a fifth of its capital actively.

Before the fund, Tangen founded and ran the London hedge fund AKO Capital for 15 years, building a reputation as a fundamental, contrarian, long-horizon investor. He trained in the arts as much as in finance — he holds a degree in social psychology and has studied art history — and is a noted collector of Nordic art. He hosts NBIM’s own interview podcast, In Good Company, in which he questions CEOs and thinkers across business, technology and markets.

Core positions

Contrarianism is stubbornness plus an open mind. To act against the crowd you must sit through long stretches where the market moves against you — yet stay willing to change your view on the evidence. The pairing is rare and, to Tangen, is what separates real contrarians from the merely obstinate.

The AI bubble and AI’s usefulness are separate questions. He reads the froth (valuations, ownership circularity, vendor financing) without denying that AI is lifting his own firm’s productivity by around 20% on flat headcount. Both can be true.

Wealth is made by owning and holding. Big fortunes come from one or two great assets held for the very long term; activity usually subtracts from returns. His ‘inertia analysis’ measures the untouched portfolio against the traded one to expose the cost of doing something.

Steady risk through losses. Most investors wrongly cut risk after a loss; the discipline — borrowed from Olympic sailors and chess champions — is to keep taking the same risk, treating each decision as independent of the last outcome.
