VinFast continued to rise, and its market value once exceeded 200 billion dollars

VinFast Auto's shares continue to rise and its market capitalisation now exceeds that of Goldman Sachs Group and Boeing (227.06, 3.65, 1.63%). One analyst warned that this showed that the market still has a lot of bubbles and needs to pull back a little harder to bring investors back to their senses.

VinFast shares closed up 20% on Monday to $82.35, a cumulative gain of 688% since it went public on August 15, and now has a market value of about $190 billion, which at one point during the session exceeded $210 billion, compared to Goldman Sachs and Boeing's $111 billion and $137 billion, respectively.
VinFast's stock surge comes at a time when the U.S. stock market as a whole has cooled. The stock has attracted the attention of retail traders targeting electric vehicle makers, and its small number of tradable shares has helped amplify the move. Options on the stock also began trading Monday, giving traders a chance to leverage bets on a rally in the stock.
Matthew Maley, chief market strategist at Miller Tabak + Co. said VinFast's rally "shows that there is still a lot of froth in the market." He added that the S&P 500's "mere" 4% drop from its summer highs hasn't caused much concern among investors, and that "it would take a full-scale pullback of about 10% to create some real panic in the market."
Retail traders' interest in the stock began to pick up last week, according to Vanda Research. That group has helped drive shares of electric car companies like Nikola) and Rivian soaring in the past.
Meanwhile, VinFast options began trading on Monday, with the most actively traded being the $100 calls - the price at which buyers can purchase the company's shares if they exceed that level by 15 September.
