Started by John Bogle in 1975, Vanguard‘s business model is unique in that it is owned by its investors. Those who invest in funds managed by the firm become owners of the company. Well-known for its role in creating index mutual funds for individual investors, the brokerage firm was quickly mimicked by other firms.
Vanguard was among the first to adopt an online portal for investors in 1995, allowing investors access to accounts, services, and educational materials.
Vanguard’s Fee Structure
Vanguard has always been proud of its low-fee services. It offers ETFs and mutual funds with no additional fees for online transactions, although there are expense ratios for managing the funds.
Options exercises and assignments are $1 per contract for accounts with less than $1 million, then $0 for the first 25 trades and $1 for all trades after that for accounts of $1 million to up to $5 million. Accounts with $5 million or more are charged $0 for the first 100 trades, and $1 per contract for all following contracts.

Following Schwab’s lead, it also offers commission-free stock, ETF, and options trades. Options trades also have $0 commissions plus a standard 65-cent-per- contract fee.
There are no minimums to invest in Fidelity mutual funds. Fidelity doesn’t charge an expense ratio fee for certain proprietary mutual funds and offers hundreds of other funds with no transaction fees.

JP Morgan
- Assets under management: $3.7 trillion
- Number of consumers served: 82 million
The oldest firm on this list, JP Morgan Chase & Co. traces its roots to the late 1700s. Its current form is a culmination of many businesses, banks, and financial service providers it has combined with over the years.
The bank’s investment services offer ETFs and mutual funds, and clients can choose between self-directed investments, using the services of a team of advisors, or having a dedicated advisor.
JP Morgan’s Fee Structure
JP Morgan personal account annual fees start at 0.6% for investments between $25,000 and $249,999. The fee lowers to 0.5% if your account balance is $250,000 or greater.
