Norway only holds $219 billion in US Treasury bonds. What investments are you talking about?
Maybe they wanted to say what you did, but accidently used the total worth of the whole Oil Fund (as it's called in Norway, because it was started with money taxed from oil companies extracting in Norwegian seas).

I make it only 1.5 trillion equities - they run about a 70 / 30 split stocks to bonds.
They could easily trim up their $50bn of Nvidia or their $50bn of Microsoft or their $40bn of Apple etc and put it to better use.
