Apple CEO Tim Cook
Apple CEO Tim Cook has helped Apple reach a $3 trillion market cap, but the iPhone maker faces issues.
  • Apple is heading into 2024 as the world's most valuable company again.
  • The company's share price is high, but hardware sales and China are areas of weakness.
  • The latest setback: Pausing US sales of the newest Apple Watch at peak holiday buy time.

It's easy to think of Apple as near-invincible.
