Now that you know which are the top 5 brokers, you are probably curious how we came up with the list. Let's go through a few points quickly. What is an online broker? Why do we think these brokers are safe? What are the most important factors when selecting the best online brokers?

What is an online broker?

Thirty years ago, if you wanted to buy a stock, you had to pick up the phone and call your broker, who executed the transaction in return for a commission. Brokers were like characters in the movie 'Wolf of Wall Street'. They were constantly monitoring stock prices while holding the phone and shouting. The Internet changed all that. Nowadays, if you want to invest in Apple shares, you open an online account, deposit money, and create an order on the broker\'s online platform. These platforms are the online brokers. Online brokers help you buy and sell securities like stocks and ETFs. After setting up your order, the online broker executes it immediately. The entire process happens online.

Are these brokers safe?

The brokers on this list are all considered safe. You can be sure none of them is a scam. They are regulated by at least one top-tier regulator.

Nevertheless, brokerage companies can still go bust. Remember the collapse of Lehman Brothers? In such cases, it is important to know what happens with your securities and cash. Your funds are usually held in segregated accounts, so even if the broker declares bankruptcy, your funds will be safe.

If, for example, the broker steals your assets, then you have a last resort: the compensation fund of the country where the broker is regulated.

How did BrokerChooser pick the best online stock brokers?

We test online brokers based on more than ~300 criteria, with real accounts and real money. We don\'t want to overwhelm you, so we will only list the five most important criteria.

You have seen the details, now let's zoom out. Here are the best stock brokers of 2021 in the US:

Interactive Brokers is our winner, having been selected the best stock broker in the US for 2021. Low trading fees. Wide range of products. Many great research tools.

We believe that all the stock brokers on our Top 5 list are a great choice. Pick the winner, or one of the runners-up, and take the next step in your investment journey. Let us know what you think in the comments section.
