Don't know your mutual funds from your hedge funds? Well, you are certainly not alone. This month, The Good Girls explain what the differences are between mutual funds, index funds, hedge funds, and ETFs (exchange-traded funds).  As usual, this conversation should not be taken as financial advice and you are strongly encouraged to speak with your financial advisor before making any investment decision.  The Good Girls will be interviewing an expert in trading in 2022.
