Norway's $1.3 trillion sovereign wealth fund, the world's largest, earned a return on investment of 1.07 trillion Norwegian crowns (€101.36 billion) in 2020, the second highest in its 22-year history.
"Despite the pandemic having put its mark on 2020, it has been yet another good year for the fund," Central Bank Governor Oeystein Olsen said in a statement.
The fund is managed by a unit of Norway's central bank.
"However, the high return also reminds us that the market value of the fund might vary a lot going forward," he said.
The return on investment was 10.9% last year, 0.27 percentage points higher than the return on the fund's benchmark index.
The fund's results were boosted by US tech stocks, with Apple, Amazon, Microsoft and Tesla contributing the most to its absolute return, presentation material showed.
"Technology companies had the highest return in 2020, with a return of 41.9%," fund CEO Nicolai Tangen said in a statement.
"This is mainly due to the pandemic resulting in a massive increase in the demand for products for online working, education, trade and entertainment," the CEO added.
Founded in 1996, the Norwegian fund holds stakes in around 9,200 companies globally, owning 1.5% of all listed stocks. It also invests in bonds and unlisted real estate.
The fund, managed by a unit of the central bank, holds the equivalent of $240,000 for every Norwegian man, woman and child.
