Zhitong Financial APP learned that because electric car manufacturers$Tesla, Inc. (TSLA.US) $Investors were not impressed by the reported fourth-quarter earnings and outlook, and the company's shares lost about $109 billion in one day.

Tesla, Inc. 's share price plummeted nearly 12% on Thursday. Earlier, on the company's earnings call, people were bullish on a humanoid robot called Optimus and bearish on the new car. On Thursday, the stock closed at $829, its lowest level since Oct. 14 and the second-biggest drop for the S & P 500 on Thursday.The last time Tesla, Inc. lost more than $100 billion in a single day was on November 9.

In a fourth-quarter earnings call on Wednesday, Tesla, Inc. CEO Elon Musk said the company would not launch any new models this year. This has disappointed many who believe that Musk's promised "updated product roadmap" will include good news about plans for Cybertruck, Semi and future cheaper models.

Edward Moya, senior market analyst at Oanda Corp, said: "it is clear that Tesla, Inc. has lost momentum because Tesla, Inc. 's lack of low-cost cars for about $20, 000 and the growing strength of competitors have really undermined his growth prospects. "

On the conference call, Tesla, Inc. 's management said that a $25000 version of its mass market model, Model 3, had not yet been developed, and stressed Tesla, Inc. 's work on artificial intelligence and self-driving.

Barclays analyst Brian Johnson wrote in a report: "when it comes to product lines, Musk has shifted from future cars (such as the Roadster or the Model 2 under $25000) to self-driving taxis and humanoid robots. Although we realize thatRobotic taxis are a key part of Tesla, Inc. 's bullish position, but we are concerned about the lack of physical product lines."

In addition, Zachary Kirkhorn, chief financial officer of Tesla, Inc., warnedRecent high input costs may affect the company's market-leading profit margins."We are also seeing inflation and rising commodity prices, which we expect to continue to put pressure on our costs. The exact impact on gross margins is uncertain.

The negative impact of Tesla, Inc. 's performance has also spread to other electric vehicle start-ups, with shares including Rivian Automotive, Lucid Group and Fisk down 10 per cent or more. Thursday's slump exacerbated the already troubled trend of these companies. Companies have been hit hard by a general sell-off in technology and growth stocks because of concerns about rising interest rates. Together, the three stocks lost more than $13 billion in market value.

Wall Street: whether Tesla, Inc. 's production capacity doubles as scheduled is a key factor affecting stock prices in the short term.

And the analysis points out that"production bottlenecks and supply chain challenges are still the main problems" mentioned in the company's letter to shareholders, which seems to frighten investors in the current environment.Gene Munster, managing partner of venture capital firm Loup Ventures, said that the financial results show that Tesla, Inc. 's current business condition is very good, but as a high-market capitalization company, investors will be a little scared when there is an unknown future.

With the opening of factories in Texas and Berlin this year, Wall Street expects delivery of more than 1.5 million vehicles for the whole year, achieving the company's promise of "an average annual delivery growth rate of 50 per cent in the next few years".

The analysis points out that compared with many automakers, Tesla, Inc. 's business has a higher degree of vertical integration, helping to deal with the chip shortage more smoothly than its competitors. Although supply chain problems still caused losses, efficiency gains and increased car production were more than offset by higher supply costs and other obstacles, including a decline in the average price of vehicles sold by the company during this period.

Investors are concerned about how quickly Tesla, Inc. can expand production at the two new plants this year, while the outlook is overshadowed by technological changes, batteries and other supply chain constraints.

's production capacity doubles as scheduled is the key factor affecting the stock price in the short term.Dan Ives, an analyst at Wedbush who has been bullish on Tesla, Inc., said the increase in production will be key to the stock in the coming months, with the two new plants expected to produce hundreds of thousands of cars this year. Joe Spak, an analyst at Royal Bank of Canada, agrees that "the key factor affecting Tesla, Inc. 's stock price in 2022 is the increase in production." he also cautioned that expanding production is one thing, whether demand remains strong is equally important, and new models need to be built on schedule.
