Frequently Asked Questions

Are online brokers safe?

Most U.S. brokers are members of the Securities Investor Protection Corporation (SIPC), which protects up to $500,000 in securities and cash (including a $250,000 limit for cash). However, SIPC does not cover market losses, commodities, futures, or promises of returns.

Can I transfer stocks between brokers?

Yes. Through the Automated Customer Account Transfer Service (ACATS), you can move stocks from one broker to another. The easiest transfers occur between like account types (e.g., IRA to IRA). Always start the process with the receiving broker.

How soon can I start trading after opening an account?

Once your account is approved and funded, you can begin trading. This process can take anywhere from a few hours to several days, depending on the broker and funding method.

What is a no-transaction-fee (NTF) mutual fund?

NTF funds are mutual funds that can be bought or sold without paying a commission or transaction fee. Many brokers offer thousands of such funds, making them cost-effective for long-term investors.

Do all brokers offer cryptocurrency trading?

Not all brokers support crypto. Those that do may charge a percentage-based fee on crypto transactions. If trading digital assets is a priority, choose a platform that offers it.

What is the difference between a broker and a robo-advisor?

A broker provides the tools for you to make your own trades. A robo-advisor makes investment decisions on your behalf based on your financial goals and risk tolerance. Some platforms now offer hybrid services.

Choosing the best online broker is a personal decision that should be based on your trading style, investment goals, and desired level of support. By focusing on low costs, usability, and the right mix of investment options, you can find a platform that helps you grow your wealth with confidence.
