New investors might want to start investing in the stock market but could be unaware of where to start or what financial products or analysis tools are available. Investing used to be conducted by expensive Wall Street brokers on behalf of their clients. Now, the best online stock brokers give new traders the power and investment advice to do with their money as they please, without ever placing a call to a broker.

How The Stock Market Works

To raise money, companies can issue stock. This stock is sold on exchanges and traded by brokers.

These shares grant stockholders a small equity stake in the company. Initially, the price of these shares is determined largely by the company and its analyst.

After the initial offering, the price of a company’s shares is determined by the market. Much like an auction, prices go up or down depending on the market’s demand for the shares.

How To Invest In Stocks

Beginning investors usually stick to three main categories of assets:

  1. Stocks
  2. ETFs (exchange-traded funds)
  3. Mutual funds

ETFs and mutual funds are common investment vehicles that are traded similarly to stocks. Both are bundles of different assets, designed to help diversify portfolios. However, there are however a few critical differences between the two.

  • The vast majority of ETF trades are managed passively and are designed to mimic the movements of certain asset classes. For example, you can buy an ETF designed to mirror the S&P 500. Because they’re more actively managedmutual funds often have higher expense ratios.
  • Mutual fund managers try to beat the market and ETFs try to mirror certain parts of the market.
  • ETFs are also traded intraday like stocks, meaning the prices change throughout the day. Mutual funds are priced once a day at the close of the market.

In general, there are two ways to make money in the stock market:

  1. From an increase in the price of the security
  2. By investing in companies that pay periodic dividends

Dividends are payments issued by a company to its shareholders. Many investors reinvest these dividends, meaning they purchase additional shares instead of taking a cash payment.

Online brokerage accounts give traders full control to buy and sell securities with just a click of a button. None of the ten brokers listed here require minimum balances or charge inactivity fees.

These modern online brokerages also make it easy and affordable to learn stock trading since most of them offer extensive educational programs and commission-free US stock/ETF trades.

Bottom Line

In addition to being reputable, all of the brokers listed here offer good resources to improve investors’ trading prowess.

Choosing a broker comes down largely to a trader’s personal preferences. Traders should find one whose price structure matches the types of assets they’d like to trade and whose service matches their needs. They should also consider whether or not it’s important to get in-person service as some brokers are 100% online.

Investing in the stock market can be intimidating at first. Luckily, modern fintech gives traders of all levels significant control over their investments.
