Vin Fast suffered an $83 billion wipeout after the EV start-up's shares plunged 44% in a single day

• VinFast stock plunged 44% Tuesday, reducing its market value by $83 billion.
• The EV maker's shares are thinly traded and it expects to sell just 50,000 cars this year.
• Before Tuesday, VinFast had soared more than 800% in one of the year's best market debuts.

VinFast's stunning stock-market debut hit a brick wall Tuesday after the EV maker's value plunged by $83 billion.

Shares in the little-known, Vietnamese company closed 44% lower, but it's still worth about $107 billion – more than double the market cap of Ford.
