Tesla's value plunged nearly $200 billion since mid-July – and Elon Musk's EV maker faces a bumpy road ahead

• Tesla's value has fallen nearly $200 billion in just over a month. 
• The EV-maker's shares have fallen about a fifth since their 2023 peak last month. 
• "Exploding" Tesla inventories could spell more trouble for Elon Musk's carmaker.

The only way for Tesla stock has been up this year – until last month at least.

Elon Musk's EV-maker had surged about 170% to peak at $291 on July 19, but has since lost about a fifth of its value.
