Nio (NYSE: NIO, HKG: 9866) was the only one of the US-listed Chinese electric vehicle trio to fall in the fourth quarter of last year. Norway's central bank, meanwhile, bought more shares in the stock's downward spiral.

Norges Bank held 13,749,756 shares of Nio's US-traded ADRs at the end of the fourth quarter, its 13F filing with the US Securities and Exchange Commission last week showed.

That's up 3,237,003 shares, or 30.8 percent, from 10,512,753 shares at the end of the third quarter.
