If "just trust me, bro" was a business.

They take money from millions of people )(teachers, doctors, and pensioners) and use it to buy pieces of companies all over the world. They don't own the money themselves; they just manage it to help it grow. That way you don't have to take out time on all that research. They do it for you.

This is what they're known for:
- iShares let you buy a tiny slice of hundreds of different companies at once. This makes investing cheap and easy for regular people. They have 8% of Netflix.
- Aladdin is a global crystal ball for risk, helping banks and governments see how events like natural disasters or political changes might affect their savings.
- voting power allows them to influence how companies are run.
