FSKAX: Fidelity® Total Market Index Fund

FSKAX or Fidelity Total Market Index Fund is created by Fidelity Investments. This fund covers a wide range of assets in the US stock exchange. FSKAX tracks common stocks in the Dow Jones US Total Market Index and invests about 80% of assets into such stocks. 

Due to the broad range of stocks, it is one of the most diversified funds in the market today. Known in full as Fidelity Spartan Total Market Index Fund, investing in it is a no-brainer.

We say this because it has a very low expense ratio of 0.02% and holds more than 3,000 stocks covering many industries. It means that the poor performance of a few stocks will not affect the fund’s overall value much, which is great news for long-term investors.

It explains why many portfolio managers and retirement investment planners use it as a core fund due to its diversity and value.

FSKAX had asset holdings worth almost $71.51 billion across 3,964 different stocks, most of which are Dow Jones Index stocks. Some of the high percentage assets you will find in FSKAX include Microsoft, Apple, Johnson & Johnson, and many others.

So if you initially had any doubt about investing in FSKAX or FXAIX, you may want to think again. Fidelity is a household name as far as fund management is concerned, and FSKAX is one of its most popular funds to date.

You will find almost all the funds in the Dow Jones as part of its holdings with positive returns posted over their last few years and beyond, as you will see from our data table.

For those looking for long-term investments or those who wish to invest in a retirement fund like 401(k), funds like FSKAX are outstanding securities to invest in because they offer long-term value.

FXAIX: Fidelity® 500 Index Fund

The second Fidelity Investments fund we want to review is FXAIX or Fidelity 500 Index Fund. Fidelity has a track record of creating popular funds for investors, and FXAIX is another success story.

FXAIX is an index fund that tracks the returns of stocks in the S&P 500 Index. For those who don’t know the S&P 500 index, this is a class created for the 500 highest market cap companies in the US stock market. These stocks are highly valued and less volatile.

FXAIX seems to invest nothing less than 80% of its investment into stocks in the S&P 500 to generate income. Another way managers earn income for the fund is to lend some of its securities. Managers also use statistical sampling techniques to identify the right stock to invest in and what proportion.

Just like in FSKAX, most of the stocks you will find in FXAIX are large-cap stocks of mega-companies like Apple, Amazon, NVIDIA, and many more. FXAIX can withstand price and industry shocks with stocks spread across different industries due to its strong diversification features.

If some selection of stocks performs poorly, it will not affect the overall performance of FXAIX as much.

FXAIX has more than 500 different holdings to the value of $399.36 billion. Since 2011 when it was launched, it has also done quite well for investors, posting a return of 18.52% over the last 5 years.

Let’s now review the top ten holdings of FXAIX. Here are FXAIX’s top 10 holdings representing 29.08% of all assets:

Microsoft Corp.6.36%
Apple Inc.6.00%
