NASDAQ 100 vs S&P 500: Which Is Better?

Updated 20 October 2026

Quick answer: The S&P 500 tracks about 500 of the largest US companies across all sectors, making it a broad, diversified benchmark of the US stock market. The NASDAQ 100 tracks the 100 largest non-financial companies listed on the Nasdaq exchange and is heavily weighted toward technology and growth companies such as Apple, Microsoft, Nvidia, Amazon and Alphabet. The NASDAQ 100 has delivered higher returns over the past 15 years or so, but with bigger swings and deeper crashes, such as an over 80% fall after the dot-com bubble. The S&P 500 is generally the better core holding for most investors; the NASDAQ 100 suits those who want extra tech exposure and can tolerate more volatility.

For investors looking beyond their home market, US stock indices are popular choices. Two names come up again and again: the S&P 500 and the NASDAQ 100. Both include many of the world's most famous companies, and both can be accessed by Indian investors through mutual funds and ETFs. But they differ in important ways.

This guide compares the two indices in detail: what they contain, how they're built, their performance and risk, how Indian investors can invest in them, taxation, and how to decide which suits you.

What Is the S&P 500?

The S&P 500, maintained by S&P Dow Jones Indices, tracks around 500 leading US companies. Key features:

Broad coverage: it represents roughly 80% of the total market value of US-listed stocks, according to S&P.
All sectors: technology, healthcare, financials, consumer goods, energy, industrials, utilities, real estate and more.
Committee selection: companies must meet criteria for size, liquidity, public float and profitability (positive earnings) to be added, and a committee makes the final decisions.
Market-cap weighted: larger companies have a bigger influence, based on their float-adjusted market value.
Listing exchange doesn't matter: both NYSE- and Nasdaq-listed companies are included.

The S&P 500 is widely seen as the best single gauge of large US companies and is the benchmark against which many fund managers are judged.

What Is the NASDAQ 100?

The NASDAQ 100 tracks the 100 largest non-financial companies listed on the Nasdaq stock exchange. Key features:

Nasdaq-listed only: companies listed on the NYSE, such as many banks, energy companies and consumer staples firms, aren't included.
Excludes financials: banks and other financial companies are left out by design.
Tech-heavy: technology companies make up roughly half or more of the index, with significant communication services and consumer companies like Amazon and Tesla.
Modified market-cap weighting: rules limit how much any single company or group of large companies can dominate, with periodic rebalancing.
Includes some non-US companies listed on Nasdaq.
No profitability requirement in the same way as the S&P 500, so some growth companies with limited earnings can be included.

How the Indices Are Maintained

The S&P 500 is rebalanced quarterly, and its committee can add or remove companies at any time due to mergers, acquisitions or changing eligibility. Companies are added when they meet size, liquidity and profitability criteria, which means some fast-growing firms join only after becoming consistently profitable.

The NASDAQ 100 is reconstituted annually in December, when companies are added or removed based on market value rankings, and rebalanced quarterly. Special rebalances can occur if a few companies become too dominant. In July 2023, Nasdaq carried out a special rebalance to reduce the combined weight of the largest companies, an example of how concentration rules work in practice.

Other US Indices Worth Knowing

Dow Jones Industrial Average: 30 large US companies, price-weighted rather than market-cap weighted. Famous but narrow.
Nasdaq Composite: nearly all Nasdaq-listed stocks, a few thousand companies.
Russell 2000: about 2,000 small US companies, often used to gauge small-cap performance.
CRSP US Total Market or Wilshire 5000: broad indices covering nearly the entire US stock market.
S&P 500 Equal Weight: holds the same companies as the S&P 500 but gives each roughly equal weight, reducing concentration in the largest firms.

Overlap Between the Two

There's significant overlap. The largest companies in the NASDAQ 100, such as Apple, Microsoft, Nvidia, Amazon, Alphabet, Meta and Broadcom, are also among the largest in the S&P 500. Because both indices are market-cap weighted, these giants have a big influence on both. In recent years, a handful of mega-cap technology stocks, sometimes called the "Magnificent Seven", have made up a large share of the S&P 500's total value.

This means owning both indices doesn't double your diversification. If you hold an S&P 500 fund, adding a NASDAQ 100 fund mainly increases your exposure to large technology companies.

Performance History

Over the long run, both indices have delivered strong returns, but their paths have differed:

Dot-com bubble (2000–2002): the NASDAQ 100 fell by over 80% from its March 2000 peak to its 2002 low, while the S&P 500 fell by about half. The NASDAQ 100 took around 15 years to regain its 2000 peak.
2008 financial crisis: both fell sharply, with the S&P 500 down more than 50% from peak to trough.
2010s to early 2020s: the NASDAQ 100 significantly outperformed, driven by the rise of large technology companies, smartphones, cloud computing and digital advertising.
2022: as interest rates rose sharply, the NASDAQ 100 fell around 33% for the year, compared with roughly 19% for the S&P 500, showing its greater sensitivity to rate changes.
2023–2025: enthusiasm around artificial intelligence drove strong gains in many large technology stocks, boosting both indices, especially the NASDAQ 100.

Past performance doesn't guarantee future results. Periods of tech outperformance can be followed by long periods of underperformance.

Risk: Concentration and Volatility

The NASDAQ 100's higher returns in recent years came with higher risk:

Sector concentration: heavy reliance on technology means sector-specific shocks, such as regulation, rising interest rates or a slowdown in tech spending, hit harder.
Company concentration: a few companies make up a large share of the index.
Valuation risk: growth stocks often trade at high price-to-earnings ratios, making them more sensitive to changes in expectations and interest rates.

The S&P 500 is also concentrated in large tech companies today, but its inclusion of financials, healthcare, energy, industrials and consumer staples provides more balance.

How Indian Investors Can Invest

1. Indian Mutual Funds and ETFs

Several Indian fund houses offer funds tracking these indices:

NASDAQ 100: ETFs listed on Indian exchanges and fund-of-funds (FoFs) that invest in them, offered by fund houses such as Motilal Oswal and others.
S&P 500: index funds and FoFs from several Indian fund houses.

These let you invest in rupees through a normal demat or mutual fund account. However, the RBI and SEBI set overall limits on how much Indian mutual funds can invest overseas. When these limits were reached, as in 2022, some funds temporarily stopped accepting new investments. ETFs listed in India may also trade at premiums to their underlying value when demand is high, so check this before buying.

2. Direct Investment Through LRS

Under the RBI's Liberalised Remittance Scheme (LRS), resident Indians can remit up to 250,000 US dollars per financial year abroad for permitted purposes, including investing in foreign shares and ETFs. Many platforms allow Indians to buy US-listed ETFs such as VOO or QQQ directly. Consider currency conversion costs, platform fees, tax collected at source (TCS) on remittances above certain thresholds, and US estate tax implications for large holdings.

3. Tax Considerations in India

International funds and foreign shares are generally taxed differently from Indian equity funds. Tax rules for these investments changed in 2023 and again with the 2024 Budget, affecting holding periods and rates. Dividends from US stocks are subject to US withholding tax, and you may be able to claim credit in India under the tax treaty. Because rules change, check the current treatment or consult a tax adviser before investing.

Lessons From the Lost Decade

Investors sometimes assume US stocks always go up. History suggests caution. From the start of 2000 to the end of 2009, the S&P 500 delivered roughly zero or slightly negative total returns in US dollar terms, a period often called the "lost decade", as it suffered both the dot-com crash and the 2008 financial crisis. The NASDAQ 100 fared even worse over that period, after its dramatic collapse from the 2000 peak.

Investors who kept investing regularly through those years benefited when markets eventually recovered, but anyone who invested a lump sum at the peak and needed the money within ten years would have been disappointed. The lessons: diversify across asset classes and countries, invest regularly, keep a long horizon, and don't assume that recent performance will continue indefinitely.

The Role of Artificial Intelligence

The rise of AI has driven enormous investment in chips, cloud infrastructure and software. Companies such as Nvidia, Microsoft, Alphabet, Amazon and Meta, heavily represented in both indices, have been central to this trend, and their gains have lifted the NASDAQ 100 in particular. Whether AI-related growth will meet investors' high expectations remains uncertain. Technological revolutions often create enormous value over time, but they can also produce periods of overexcitement followed by sharp corrections, as the dot-com era showed.

The Currency Factor

When Indian investors buy US index funds, returns depend on both the index and the US dollar-rupee exchange rate. Historically, the rupee has gradually weakened against the dollar, which has added to rupee returns from US investments. But currency movements can also reduce returns in some periods. US investments also provide diversification against risks specific to India's economy.

Valuation: What You're Paying For

Valuation measures such as the price-to-earnings (P/E) ratio show how much investors pay for each rupee or dollar of company earnings. The NASDAQ 100 has generally traded at higher P/E ratios than the S&P 500, reflecting expectations of faster growth. Higher valuations can be justified if growth materialises, but they also leave less room for disappointment. When growth slows or interest rates rise, highly valued stocks can fall sharply, as in 2022. Valuations aren't good timing tools, but they help set realistic expectations for future returns.

An Illustrative SIP Example

Suppose an investor puts 10,000 rupees a month into a US index fund for 15 years, investing a total of 18 lakh rupees. If the fund earned 10% a year in rupee terms, the investment would grow to roughly 42 lakh rupees. At 13% a year, it would be roughly 56 lakh rupees. The higher figure might resemble a strong tech-led period; the lower one a more average outcome. The point isn't to predict returns, but to show how growth rates and time interact, and why sticking with a disciplined SIP matters more than picking the perfect index. (Figures are illustrative and not guaranteed.)

Common Mistakes to Avoid

Chasing recent returns: buying the NASDAQ 100 only because it did well last year.
Overconcentrating: holding both indices plus individual tech stocks, unknowingly creating a very tech-heavy portfolio.
Ignoring ETF premiums on Indian exchanges during periods of high demand.
Forgetting currency risk and assuming rupee depreciation will always boost returns.
Selling in panic during sharp falls.
Neglecting tax rules, which differ from Indian equity funds.

Which Should You Choose?

Choose the S&P 500 If You:

Want broad, diversified exposure to the US economy.
Prefer lower volatility within US equities.
Are building a core long-term international holding.
Value some dividend income and sector balance.

Choose the NASDAQ 100 If You:

Believe strongly in long-term growth of technology and innovation.
Can tolerate larger, longer drawdowns.
Already have a diversified core and want a growth-oriented satellite allocation.
Have a long time horizon, ideally ten years or more.

Or Combine Them

Some investors use the S&P 500 as their core US holding and add a smaller NASDAQ 100 allocation for extra growth exposure. Keep in mind the overlap and the resulting concentration in large tech companies.

Why Diversify Beyond India?

Access to global leaders: many of the world's biggest technology, healthcare and consumer companies aren't listed in India.
Different economic cycles: US and Indian markets don't always move together, which can smooth overall portfolio returns.
Currency diversification: holding dollar assets can help with future dollar expenses like overseas education or travel.
Sector balance: Indian indices are heavy in financials and energy; US indices add exposure to global tech and healthcare.

At the same time, international investing adds currency risk, different tax treatment and sometimes higher costs, so it works best as a measured part of a broader plan.

Choosing a Fund: A Checklist

Which index does it track, and how closely (tracking error)?
What is the expense ratio, including any underlying ETF costs for FoFs?
Is it accepting fresh investments, given overseas investment limits?
For ETFs, how liquid is it, and does it trade near its NAV?
What are the tax implications for your holding period?
Does it fit your overall asset allocation?

How Much International Exposure Should Indians Have?

There's no fixed rule, but many financial planners suggest Indian investors hold around 10% to 30% of their equity portfolio in international funds for diversification, depending on goals such as overseas education or travel, risk tolerance and investment horizon. India's own markets offer strong growth potential, so international exposure is usually a complement rather than a replacement.

Investing Tips

Invest through SIPs to spread purchases over time.
Check expense ratios and tracking error when choosing funds.
Compare ETF prices with their indicative NAV to avoid paying large premiums.
Stay invested for the long term; both indices can fall sharply in the short term.
Rebalance periodically to keep your international allocation on target.
Avoid chasing recent performance; last year's winner isn't always next year's.

Frequently Asked Questions

Which has better returns, NASDAQ 100 or S&P 500?

Over the last 15 or so years, the NASDAQ 100 has delivered higher returns, but over some other periods, such as 2000 to 2010, the S&P 500 performed far better. Future returns are uncertain.

Is the NASDAQ 100 riskier?

Yes. Its concentration in technology and growth companies makes it more volatile, with deeper falls during downturns.

Can I invest in both from India?

Yes, through Indian mutual funds and ETFs that track them, or directly through US brokerage accounts under the Liberalised Remittance Scheme.

Do these indices pay dividends?

Many companies in both indices pay dividends, but yields are typically low, especially for the NASDAQ 100. Index funds may reinvest dividends (growth options) or distribute them.

What is the difference between the Nasdaq Composite and the NASDAQ 100?

The Nasdaq Composite includes almost all stocks listed on the Nasdaq exchange, a few thousand companies. The NASDAQ 100 includes only the 100 largest non-financial ones.

Should I invest a lumpsum or SIP in US index funds?

SIPs spread purchases over time and reduce the risk of investing everything at a peak. For lumpsums, many investors use a systematic transfer over several months.

Is now a good time to invest in US markets?

No one can reliably time markets. For long-term investors, regular investing and holding through cycles matters more than entry timing.

What happens to my investment if the rupee strengthens?

If the rupee strengthens against the dollar, the rupee value of your US investments falls, even if the index itself is unchanged. Currency movements can work for or against you in any given period.

Are there Indian equivalents to these indices?

Yes. The Nifty 50 and Sensex track large Indian companies, similar in spirit to the S&P 500. The Nifty IT index tracks Indian technology companies, though it's very different from the NASDAQ 100 because Indian IT firms are mainly service companies.

Can I lose all my money in an index fund?

It's extremely unlikely for a broad index to go to zero, since that would require all its companies to fail. But index funds can fall significantly, sometimes by half or more, during severe downturns, and take years to recover.

How do I track these indices daily?

Financial news websites, brokerage apps and the official websites of S&P Dow Jones Indices and Nasdaq publish live and historical index values.

Which is better for a beginner?

For most beginners, the S&P 500 is a simpler, more diversified starting point. The NASDAQ 100 can be added later as a smaller, growth-focused allocation once you're comfortable with volatility.

Do I need a US bank account to invest?

No. Indian mutual funds and ETFs give access without one, and many international brokerage platforms let Indian residents invest through LRS remittances from an Indian bank account.

How often should I review my US index investments?

Once or twice a year is enough for most long-term investors: check your allocation, costs and whether the investment still fits your goals.

Final Thoughts

The S&P 500 and NASDAQ 100 both offer access to some of the world's most successful companies. The S&P 500 provides broad, balanced exposure to the US economy and is a strong core holding. The NASDAQ 100 offers a concentrated bet on technology and growth, with higher potential returns and higher risk. For most Indian investors, a modest, diversified international allocation, built gradually and held for the long term, is a sensible complement to a core Indian portfolio.
