Recently, Tesla stock showed a downward trend。The weakness comes as Cathie Wood's Ark Investment Management aggressively bought $35 million worth of Tesla stock last Thursday (March 14).。

Tesla will release its earnings report after the U.S. stock market on Wednesday (October 18)。As the earnings report approaches, the market's various predictions for Tesla have been "flying"。

On August 7, local time, Tesla's filing with the SEC showed that the company's CFO Zachary Kirkhorn resigned from the company on August 4 and will be replaced by the current chief accounting officer Vaibhav Taneja.。

On June 26, Goldman Sachs downgraded Tesla's rating to "neutral" from "buy."。The reason is that Tesla's current stock price already contains a "positive long-term view" of the company's growth and competitive positioning, and the pricing environment for Tesla's new cars is difficult.。Goldman Sachs isn't the first big bank to pour cold water on Tesla, and last week, Barclays and Morgan Stanley also downgraded Tesla's rating.。
