Tesla saw a $56 billion stock rout in a single day, an amount that dwarfs Ford's market cap

• Tesla saw its value plunge by almost $56 billion in one day, an amount that dwarfs the individual market caps of Ford and General Motors.
• That was driven by a selloff in the EV maker's shares after it reported first-quarter earnings that missed estimates.
• The automaker still has $515 billion in market cap - making it the 9th most valuable company in the world.

In just one day, Tesla saw its market value plunge by almost $56 billion, an amount that dwarfs the individual market capitalizations of two of its main American competitors: Ford and General Motors.
