Axos offers investors a vast array of investment choices, including stocks traded on US exchanges such as the S&P 500, the New York Stock Exchange, and the NASDAQ. You can also trade mutual funds and ETFs on the platform. So it's easy to build a diversified portfolio using the platform. Most trades are commission-free, which reduces the cost of investing versus investing through a traditional stock broker. Trading options and mutual funds do involve paying fees: $1 per option contract and $9.95 per mutual fund trade. You can trade 24 hours a day, seven days a week through Axos. Axos offers a mobile app, where customers can make trades and manage all of their Axos accounts in one place, 24/7.

Axos earns a C rating from the Better Business Bureau. Consumers who review the company on Trustpilot award the company just 2 out of 5 stars, which amounts to a poor rating. Customers complain of poor customer service, but to be fair, many complaints have to do with Axos products other than its self-directed investment platform. We also noted that customers complained of not receiving promotional bonuses promised when they opened an account. Axos doesn't publish a Contact Us page, though we were able to glean from other sources that you can contact the company by phone or via email. The company also offers a proprietary app, through which customers can manage all of their Axos accounts in one place. Axos doesn't list its customer service hours but we can assume that there is no 24/7 customer service available.
