Vanguard

Started by John Bogle in 1974, 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 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, $0 for the first 25 trades, and $1 for all trades after that (accounts of $1 to $5 million). Accounts with more than $5 million are charged $0 for the first 100 trades, and $1 per contract for all following contracts.
