A number of asset management firms recently reported their positions for the fourth quarter of 2020, from which we can see how some of these giant whales moved in their Nio positions.

Bridgewater Associates, the world's largest hedge fund, increased its holdings in Nio ADS by 391,200 shares in the fourth quarter, according to a 13F filing released on February 12.

As of December 31, 2020, Bridgewater held 1,960,609 Nio ADS shares valued at $95,560,000.

It is also worth noting that Bridgewater continues to be bearish on Tesla despite the fact that the stock is one of the hottest investments in 2020 with a 743.44% gain for the year.

Bridgewater dumped its last 35,000 shares of Tesla in the fourth quarter, and the fund has continued to reduce its holdings in Tesla after buying 212,000 shares in the fourth quarter of 2019.

What we didn't notice before was that the Swiss National Bank, Switzerland's central bank, is also an investor in Nio.

The central bank's 13F filing, published on February 5, showed it held 3,026,598 Nio ADS shares worth $147,516,000 as of December 31, 2020.

The central bank's position data, published in late November, showed that it held 2,226,658 Nio ADS shares worth $47,250,000 as of September 30, 2020.

That means the Swiss National Bank increased its holdings in Nio ADS by 799,940 shares, or 35.93%, during the fourth quarter.

French bank Natixis's 13F filing, published on February 12, showed that it bought Nio ADS shares for the first time in the fourth quarter.
