Elon Musk's wealth drops by $22 bn, his 4th-largest one-day loss

World's richest person Elon Musk's net worth dropped by $22.2 billion to $358 billion on Tuesday, marking his fourth-biggest one-day loss. This came after Tesla's shares, a major contributor to Musk's wealth, fell over 8%, taking the company's m-cap below the $1 trillion mark. The latest decline follows reports saying Tesla's sales in Europe plunged by almost half in January.
