Tesla took his worst turn yesterday. After it was found that the share of the builder of electric cars is not included in the S&P 500, the share Tesla decreased by 21 percent. Investors had speculated that the car manufacturer would find a place in it. Since last week Tesla’s share of the Nasdaq Technology has already dropped by a third – from around 500 to 330 dollars. On the other hand, since the beginning of this year, the price has risen explosively. According to Business Insider, this is an increase of almost 800%. Many stock exchange experts find Tesla’s price overvalued. “We think this is one of the greatest House of cards of all time. And that it’s about to collapse,” said American stock market expert David Trainer to CNBC last weekend. According to him, the current stock market price implies a future profitability of the company that should be higher than in an extremely positive scenario. Stock exchange analyst Nico Inberg of the IEX investor website also thinks that Tesla’s strong price increases are now over. That’s what he says in the Belgian newspaper today. ,Tesla is doing well, but there was a tremendous amount of air blown in the course,” it sounds. “Trading data from the popular American investment firm Robinhood show that a large group of retail investors have jumped on a few shares, including Tesla.” The price of Nikola, another builder of electric vehicles, just increased by 40% yesterday. This happened after General Motors (GM) announced that they would invest $ 2 billion in Nikola, in exchange for an 11% stake. At the stock exchanges in New York yesterday, tech funds in particular took a firm step backwards. Big names like Amazon, Apple and Facebook were in the red. The Techmeter Nasdaq lost 11% in the space of a week.
