If you are familiar with mutual funds, segregated funds are mutual funds but with a guarantee. Every segregated fund will guarantee that you will get back either 75% or 100% of whatever you put into it, no matter what the market does! If the stock market drops 50%, giving you a heart attack, through a segregated fund you will receive either 75% or 100% of every dollar that you put in, despite it now being worth only 50%.
It puts some insurance on your investments.
Segregated funds have unlimited potential growth through investing in a variety of funds and limits any potential losses.
