What trading platform offers the most fractional US stocks?

According to our research, Interactive Brokers has the widest range of fractional shares on the major US trading platforms.

Fractional shares are a great way of investing building a diverse portfolio if you only have a small amount to invest. 

This is because if you only have $500 to start investing you can buy $100 of five stocks instead of having to buy whole shares.

Which is particularly important if you are trading popular stocks like Tesla, which can cost upwards of $200.

The downside, though is that you can’t trade with direct market access and get inside the bid offer price. But this only really makes a meaningful difference if you are trading in large amounts. When fractional shares would not be that appropriate anwya.

    • Some brokers are better for beginners and other brokers offer investment products that are only suitable to experienced traders with a high risk appetite. Make sure you choose a broker that is best for your level of investment experience.

As a rule you should think in percentages of your net worth. The higher the risk the lower the percentage of you net worth you should allocate to it.  All investments (even the safest) come with risk so be prepared to lose money as well as profit from the stock market.

Always stay within your comfort zone and never invest money you cannot afford to lose.

Investing in two stocks for example is more risky that investing in twenty. This is because you are diluting your exposure to things going wrong. For example if you hold a stock which has a profit warning and loses 50% of it’s value.  It will have a greater impact on your net worth if you have a portfolio of two stocks rather than twenty because you will hold a greater value of it.
