At Fidelity, investors will find over 11,500 mutual funds on the broker's website. Roughly 1,800 are no-load, no-transaction-fee products. Capital One Investing offers approximately 1,000 funds. About 400 of these come with no transaction fee and no load.

Overall, Vanguard takes the category.

Trading Tools

Fidelity's website is simple to navigate. It contains a lot of helpful educational and research information. These resources are in article, video, inforgraphic, and course format. The website has a simple trade ticket that appears in the left-hand side of the browser. It can be used for trading, but not charting. An advanced desktop platform is available for Fidelity customers who execute a minimum number of trades every quarter. The firm is one of the few brokerages to have an app for Apple TV.

The Capital One Investing website is user-friendly, but doesn't have as much material as the Fidelity website has. There is a simple trade bar at the bottom of Capital One's site. However, trades cannot be placed from it. Rather, it provides basic trade data, such as bid-ask spread. The broker does not have a desktop platform.

Compared to Fidelity and Capital One, Vanguard's website is much harder to navigate. It takes several minutes of searching just to find the broker's ETF screener. The website's drop-down menus produce pages that require more searching and navigation. A search field in the top right of the website makes finding your way around the site a little easier. There is no advanced platform or trade bar from this broker.

Despite Ally Invest's low fees, the broker's website is well laid out. Helpful menus at the top of the site make navigation fairly straightforward. However, there is less information on the Ally Invest site compared to Fidelity. There is a trade bar at the bottom of Ally Invest's site. Trades can be placed from it, but it's not able to produce a chart. The broker provides a simple browser-based platform called Ally Invest LIVE free for all clients. A more advanced desktop system is available for active traders.

The victory here goes to Fidelity.

Mobile Apps

Trading on mobile devices is available at all four brokers. Fidelity is the only firm to provide live streaming of financial news and a platform for Apple Watch. The Fidelity app also has a library of on-demand videos. On the Vanguard app, account documents are accessible in pdf format, although it lacks many other features, such as streaming business news. The Capital One Investing app has neither charting nor mobile check deposit. The Ally Invest platform has alerts and charting, but trading mutual funds is not possible.

The category is awarded to Fidelity.

Alternative Investments

In addition to the normal range of securities, Ally Invest also offers forex trading. None of the other three brokers provide futures or forex. Ally Invest customers can also use a dedicated forex platform at no cost.

Ally Invest wins here.

Banking Features

Fidelity is the only firm to offer a cash management account that is free. Ally Invest charges $20 for check writing and $35 for a debit card but it has been acquired by Ally Bank so its banking services will definitely improve in 2019. Capital One Investing does not offer these amenities at any price (strange given that it's owned by a bank). Vanguard requires an account balance of half a million dollars to apply for cash management services.

Fidelity easily wins here.


Ally Invest: Up to $3,500 cash bonus + commission free trades for new accounts.

Fidelity: Get 500 free trades with $100,000+ deposit.

Capital One Investing: no promotion.

Vanguard: no promotion.


Vanguard won one category, Capital One Investing didn't place, Fidelity succeeded in 4 categories, and Ally Invest managed to take two victories including the most important, Pricing category. Fidelity is the winner. Despite Fidelity's good performance, Ally Invest is an excellent choice for investors seeking the best value in investment services, while Vanguard is a good selection for mutual fund and ETF traders.
