A conseiller chargé des investissements is someone who helps people decide where to put their money so it can grow. Imagine you have a piggy bank where you save your allowance each week. A conseiller chargé des investissements is like the grown-up version of that piggy bank.
They help people make smart choices about where to put their money so it can grow into even more money. They might suggest putting some money in stocks (which are like pieces of ownership in different companies) or in bonds (which are like IOUs that people or companies pay back with interest).
Just like your piggy bank, they also help people keep track of their money and make sure it stays safe. They do this by researching different investment options and keeping an eye on how the money is doing over time.
Overall, a conseiller chargé des investissements is like a helper who wants to make sure your money is doing its best to grow into even more money for you.
