Okay kiddo, let me explain to you what a chief investment officer (CIO) is.
Do you know what an investment is? It's when you give someone some money to buy something, with the hope that it will make more money in the future. For example, if you give me $5 to buy a lemonade stand, maybe I can sell lemonade for $10 and give you back $7. That means I made a profit of $2 and you made a profit of $2.
Now, imagine if someone has a lot of money, like billions of dollars. They can't just put all that money under their mattress or in a piggy bank, right? They need to invest that money so it can grow and make even more money.
That's where the CIO comes in. The CIO is like the boss of a company that manages investments for other people. They are in charge of making decisions about where to put all that money: should they buy stocks, bonds, real estate, or something else entirely?
The CIO has to be really good at predicting what will happen in the future so they can make smart decisions. They also have to be really good at math so they can calculate how much money they can make from different investments.
So basically, the CIO is like the captain of a ship, leading a team of people who manage other people's money and try to make it grow.
