There are numerous types of investment accounts. There are a plethora of services offered with both discount brokers and full service brokers. Most people go to full service brokers because they like face to face transactions and customer service while others prefer internet based discount brokers because they don’t value face to face interactions. Since Millennials are tech savvy and don’t have money to be throwing away for steep fees, most young investors go the discount route.
I own an account with a discount broker because I like to micro manage my investments and I firmly believe Millennials should go in this direction as well. Most accounts are free to open, and I highly recommend using TD Ameritrade because of their vast array of pointers and customer service that goes above and beyond most other companies.
Savings accounts do have great benefits. Savings should be allocations of cash put aside for short term goals. Savings should also be used for personal expenses like loan payments, utility bills, and insurance. Savings accounts should also be used for anything in life that will require a large amount of cash in five years or less. The stock market can fluctuate and losing value of money while trying to achieve a short term goal is counter productive.
