If you’re investing in US stocks, then you’ve probably come across the S&P 500 and the Nasdaq. But what’s the difference between the S&P 500 and the Nasdaq and which should you invest in? Let’s dive in and take a closer look.
The S&P 500 is a stock market index and the Nasdaq is a stock exchange. There’s a lot of overlap between the two because plenty of stocks listed on the Nasdaq exchange are also members of the estemeed S&P 500 list. So, many of the top 10 stocks are the same. If you’re invested in both, you may not be as diversified as you think. Here are the top 10 stocks in both indices.
What is the best S&P 500 vs Nasdaq index fund?
The best Nasdaq or S&P 500 index fund will depend on your circumstances.
All S&P 500 index funds should be tracking the full index, whereas with the Nasdaq stock exchange, it’s the Nasdaq 100 that tends to be the most popular index fund, which only contains 100 stocks.

Nasdaq
Nasdaq 100 and S&P 500 overlap

The Nasdaq Composite Index was launched in 1971 and had an initial value of 100. It includes all the companies listed on the Nasdaq stock exchange.
It shouldn’t be confused with the Nasdaq 100, which as index containing the biggest 100 companies in the Nasdaq stock exchange. The Nasdaq is the second biggest stock exchange in the US after the New York Stock Exchange (NYSE).

What is the S&P 500?
The S&P 500 was founded in 1982 and it includes 500 of the largest companies trading on all 3 of the main US stock exchanges: the NYSE, Nasdaq and Cboe.
The S&P 500 has strict criteria for its constituents. A company must have a market cap of at least $14.6 billion, be highly liquid and the public must own at least 10% of its shares.
The S&P is spread across a wider range of sectors than the tech-heavy Nasdaq index. This means it’s slightly less exposed to concentrated crashes within one sector.
Which is the best investment, the Nasdaq or the S&P 500?
The best investment for you depends on your investment goals. Here’s a summary of what to consider:
- Are you looking for current income or future potential growth? If you want future growth then stocks listed on the Nasdaq may be suitable but if you want current income then the S&P 500 may be more useful.
- What is your attitude to investment risk? The tech heavy Nasdaq index tends to be more volatile in price movements compared to the S&P 500 as it contains a higher concentration of tech-focused growth stocks.
- What other investments do you hold in your portfolio? The S&P 500 and Nasdaq overlap in som eareas, so you need to check what else you hold within your portfolio if you want it to be diversified. If you want more exposure to tech stocks then the Nasdaq could be a good choice, but the S&P 500 still has a strong tech offering.
Nasdaq vs S&P 500 chart
Nasdaq vs S&P 500: Which is bigger?
The S&P 500 contains 500 of the biggest companies in the US whereas the Nasdaq Composite contains more than 3,000 stocks. However some Nasdaq companies are very small and the total value of the Nasdaq Composite is actually lower than the S&P 500.
Nasdaq vs S&P 500: Which is worth more?
The S&P is worth an eye-watering $50 trillion (about £40 trillion). In contrast, the NASDAQ composite index is worth a grand total of around $20 trillion (around £16 trillion) despite having over 3,000 stocks in total. That’s because it includes a large proportion of smaller tech companies.
Nasdaq vs S&P 500: Concentration
Both the Nasdaq and the S&P 500 are extremely concentrated, with the largest companies making up a big proportion of the total market value of the index and the exchange.
For the Nasdaq, the top 20 companies are mainly tech giants and account for 47% of the overall value of the index. Likewise, the S&P 500 is extremely concentrated towards the biggest companies with just 4 companies making up nearly 21% of the S&P 500 index
Nasdaq vs S&P 500: Stock quality
Quality investing is where investors look for certain criteria in their investments. It’s based on management credibility as well as balance sheet stability and financial performance.
The S&P arguably contains a higher proportion of quality stocks than the Nasdaq. That’s because they need to meet a strict verification criteria to be included in the S&P 500.
If you want to invest purely in quality stocks then you could choose the S&P quality index which is a pre-vetted group of quality companies which are selected based on return on equity and other financial ratios.
Nasdaq vs S&P 500: Which is more diversified?
Both indices are fairly diversified as you will spread your investment across many underlying US stocks. But both indices are also heavily weighted towards the bigger companies. For example, if you invest purely in the S&P 500 index then 21% of your investment will be in the top 4 biggest companies in the index.
Instead, most experts recommend that you also diversify your investments across different asset classes and different geographical areas. Then you won’t be too badly affected if one business fails.
Is it better to invest in the S&P 500 or the Nasdaq?
Whether the Nasdaq or S&P 500 is best for you will depend on your circumstances and the other funds and assets in your portfolio.
If you want more exposure to potential growth stocks then the Nasdaq might be a good choice with its emphasis on tech stocks. If you prefer a more general US index fund then the S&P might be right for you as you’ll be invested in 500 of the biggest companies in the US.
