Okay kiddo, so let's pretend you have some money saved up and you want to invest it to make more money. A stockbroker is like a helper who knows a lot about investing and can help you decide which companies you should invest in.
When you invest in a company, it means you are buying something called stocks. Stocks are like little pieces of that company that you can own a part of. So if you buy stocks from a company, you become a part-owner of that company.
The stockbroker's job is to help you choose which companies you should buy stocks from. They will look at lots of things to help you decide, like how well the company is doing financially and what kinds of products or services they sell.
Once you have decided which stocks you want to buy, your stockbroker will help you actually buy them. This means they will use your money to buy the stocks for you.
After you own the stocks, your stockbroker will keep track of how they are doing, and make sure you know what is happening. They might tell you if things are going well and your stocks are making money, or if things are not going well and you might want to sell your stocks.
So basically, a stockbroker is like a helper who knows a lot about investing and can help you make good choices when buying stocks.
