Cathie Wood, head of Ark Investment Management and manager of the popular Ark Innovation ETF (ARKK), expressed her bullishness in a Yahoo Finance interview on the potential of Baidu building cars.

Wood said if she had to name a Chinese company in automotive that she was most bullish on, it would be Baidu. As of December 14, ARK held 500,000 shares of Baidu ADRs.

With about 150 to 200 electric car makers in China today, many of which with government subsidies, there is going to be a bloodbath, she said.

ARK isn't sure if it believes that the Chinese government sees Baidu as a self-driving platform, and it's not clear if Baidu will be drawn into the race, but Baidu is certainly doing some very interesting things, Wood said.

Electric vehicles are still the focus of ARK's future attention for now. Tesla is ARKK's largest holding, an investment that has put ARK at the top of the industry.

Given that General Motors is beginning its transition to electric vehicles and that Faraday Future is about to go public, all of this news suggests that the capital markets will fund the transition from traditional to electric vehicles, which is fantastic, she said.

ARK believes Tesla is still the leader in the electric vehicle industry. Even in China, Tesla is the No. 1 electric car brand. But for competitors, there is still room for them to enter the industry, she said.

Nio is a company that is replacing charging with battery swap, and it could win the day, she said.

But Nio fans on Twitter quickly pointed out that Wood misunderstood Nio, as the company's vehicles can be charged like traditional electric cars, with battery swap as an additional power replenishment option for users.

Wood also mentioned that Xpeng Motors, which she said mimics Tesla and could also win.

BYD started out as a battery maker, and Warren Buffett's stake in the company over the years suggests it has done well, she claims.

Geely bought Volvo and the chairman also has a stake in Daimler. The company is also doing a lot of interesting things, such as working with many companies, including Baidu, she said.

The electric vehicle industry still has a lot of room to grow, Wood said, adding that electric vehicle sales will grow from about 2.2 million in 2020 to 40 million by 2025.
