S&P 500 vs. Nasdaq: Which One is Better?

There is a question I get asked all the time: “Tom, if you’re excited about new technologies and disruptive companies, why do you prefer the S&P 500 over the Nasdaq for a broad market investment?” 

It seems counterintuitive at first, right? If I love analyzing growth opportunities, especially those that originate in the tech sector, why wouldn’t I want an index that’s so heavily dominated by the very companies I tend to discuss?

Well, I want to take you behind the scenes of my thinking and share with you the reasoning that underpins my decision. This journey will touch on my own background, the core of my investing philosophy, the psychology of market drawdowns, and why I ultimately conclude that the S&P 500 is a more robust “default” or “core” holding for most investors than the Nasdaq, despite all the apparent allure the Nasdaq holds.

And just to clarify, when I talk about the “Nasdaq,” I’m typically referring to the Nasdaq 100, an index that tracks 100 of the largest non financial companies listed on the Nasdaq exchange. This narrower group represents giants like Apple, Microsoft, Amazon, Alphabet, Meta, Tesla, and a few others that together hold an enormous slice of the Nasdaq’s total market capitalization. It’s often what people buy when they want to gain exposure to the biggest names in technology and tech driven innovation.

I’m not here to dismiss the undeniable success of those companies or the Nasdaq’s remarkable returns over certain time periods. I’m also not saying you shouldn’t own tech stocks.

Rather, I’m suggesting that if you’re looking for a broad market index, one that’s intended to be the bedrock of your long-term portfolio, there are strong reasons why I personally prefer the S&P 500 over the Nasdaq 100. By the end of this piece, you’ll understand not just what I believe, but why I believe it.

My Background and Approach

I’ve spent years investigating businesses, analyzing their fundamentals, and exploring how global economic trends shape their futures. I’m known for diving into the details: from reading SEC filings to dissecting competitive moats, from comparing price to earnings ratios to evaluating free cash flows and margin expansions.

Although I love the deep detective work of researching individual companies, one crucial lesson I’ve learned over time is that not everyone has the desire or the time to become a full time investment analyst.

At the same time, I believe that we all deserve to benefit from the long term wealth building potential of the stock market. When approached intelligently, the market is a profound mechanism for turning patience and consistency into real financial gains. And so, quite often, I’m a proponent of index investing, at least as a core strategy for those who want to participate in broad equity growth without obsessing over the day to day gyrations of individual stocks.

While it can be fun (and sometimes lucrative) to pick single names, especially in the tech space, where I frequently do my deeper analyses, most people can do well by simply investing a large portion of their capital in a broad market index and consistently adding to it over time. That’s the foundation on which you can build. Then, if you have the expertise, energy, and temperament, you can layer on other positions or strategies around that core.

Understanding Index Investing

Let’s start with a quick overview of why index investing has taken off so significantly:

• Diversification: An index like the S&P 500 contains hundreds of companies spanning numerous sectors, from technology and finance to healthcare, consumer staples, and industrials. By owning an index, you’re effectively placing a bet on multiple companies rather than trying to guess which five or ten might outperform the rest.

• Low Cost: Many index funds or ETFs charge minimal fees, meaning you don’t lose a big chunk of your returns to high expense ratios. Over decades, that small difference in fees can compound into a huge amount of money saved.

• Historical Performance: If you look at the historical performance of broad market indices in the U.S. over many decades, you’ll find that they often deliver 7–10% annual returns on average (including dividends and capital gains, before inflation). While there can be stretches of underperformance or volatility, the overall trend has been upward when measured over long horizons.

These three aspects, diversification, low cost, and historically solid performance, make index investing incredibly appealing, particularly for newer investors or those who have no interest in actively managing dozens of individual positions.

The real question then becomes: which index should you choose? And that’s where the S&P 500 vs. Nasdaq conversation often begins.

The Allure of the Nasdaq

I get the draw. I really do. On paper, the Nasdaq-100 can look like the perfect vehicle for capitalizing on the global shift to a tech-centric economy. After all, we’ve seen how Amazon revolutionized e-commerce, how Alphabet (Google) became practically synonymous with “search,” how Apple turned smartphones into personal portals for every aspect of our daily lives, and how Microsoft morphed from a Windows-centric enterprise into a cloud computing juggernaut.

If you look at some five year or ten year stretches, the returns on the Nasdaq 100 can outshine those of the S&P 500. It makes sense: in bull markets that favor high growth, high innovation sectors, the Nasdaq tends to surge upward, often at a faster clip than more broadly diversified indices.

And to be fair, if someone told me, “I’m comfortable with massive volatility, and I want to overweight technology in my portfolio,” I can’t say that’s inherently wrong. But most people, in my experience, aren’t truly prepared for the type of rollercoaster ride that the Nasdaq can sometimes take us on. That’s the key distinction here: your ability to handle those downs as well as the ups.

The Reality of Sector Concentration

One of my biggest reservations with the Nasdaq as a core holding is what I like to call the “concentration trap.” Remember, while the S&P 500 invests in 500 of the largest U.S. companies, the Nasdaq-100 invests in 100 of the largest non-financial companies listed on the Nasdaq exchange. It sounds like 100 is a decent spread, after all, that’s more than a handful of stocks. But if you look at the actual weightings of the top 10 companies in the Nasdaq-100, you’ll see they can account for nearly half the entire index.

That’s a huge deal. Those top 10 names, overwhelmingly in tech, dictate a massive portion of the index’s movement. If Apple, Microsoft, Amazon, Alphabet, Tesla, Meta, and a few others catch a cold, the entire index essentially catches pneumonia. Meanwhile, in the S&P 500, even though those names are still big dogs, you also have companies from other sectors—banks, healthcare giants, consumer staples, that help spread out the risk.

This difference matters profoundly during corrections or bear markets. If the entire economy is struggling, both the S&P 500 and the Nasdaq are likely to go down. But if a downturn is focused on technology, or if something shifts in consumer or corporate spending that disproportionately hurts tech, the Nasdaq can plummet at a far steeper rate. That’s exactly what we’ve seen in previous market cycles.

Drawdowns: The Unspoken Truth

Let’s talk about drawdowns, periods when the market or an index falls significantly from a recent high. I’ve noticed that many new investors, or even somewhat experienced ones, tend to look at the “glory periods” on performance charts without paying enough attention to what happens when the market heads south.

• Dot-Com Crash (2000–2002): The Nasdaq famously plummeted over 70% from its peak. Many tech companies that had soared based on nothing more than hype and “dot-com mania” ended up bankrupt or severely diminished. It took more than a decade for the Nasdaq to fully recover and surpass its dot-com era highs.

• 2008 Financial Crisis: While both the S&P 500 and the Nasdaq saw painful declines, the Nasdaq’s tech-heavy composition contributed to especially wild price swings for certain holdings. Some investors who were overexposed to tech bailed out near the bottom, locking in monumental losses that took years to recoup—if they ever returned to the market at all.

• 2022 Downturn: Although the markets had a dramatic rally after the COVID-19 crash in 2020, in 2022 we saw a reset, especially among growth and tech names. The Nasdaq faced bigger losses than the S&P 500 because interest rate hikes, inflation worries, and investor rotation away from high-growth, high-multiple companies weighed more heavily on the types of stocks that dominate the Nasdaq.

These episodes underscore a key point I try to drive home: for most retail investors, the emotional and psychological impact of a 50% or 70% drop can be devastating. It’s one thing to read about it in a textbook; it’s quite another to watch your hard-earned retirement savings plunge so dramatically within months. If you’re convinced you can handle that with zen-like calm, fine—but in my experience, even seasoned pros can feel a surge of panic when the floor seems to be falling out from under them.

The Psychology of Market Turmoil

I can’t emphasize enough how important psychological fortitude is when it comes to investing. Far too often, people dive in when markets are euphoric. They see rising charts, hear endless excitement in the media, and pour money into whatever is hot. Then, at the slightest sign of trouble—particularly if they’re in a more volatile vehicle like the Nasdaq—they question everything, panic, and capitulate.

Panic selling usually means crystalizing losses. And ironically, it’s the opposite of what you might logically want to do. In an ideal world, you’d buy more shares when prices are low; in reality, many people sell when the fear sets in. Understanding your own emotional tolerance is one of the greatest challenges in investing.

That’s why I lean heavily toward the S&P 500 as a “safer” or more stable core. Sure, it can still drop 30%, 40%, or more in a severe bear market. But historically, it’s shown less extreme volatility than the Nasdaq. Additionally, because it’s diversified across numerous sectors, you’re less likely to see a meltdown that’s triggered by a single sector.

Why the S&P 500?

Now, let me dig into the specifics of why I prefer the S&P 500 as a broad market index:

• Sector Diversification: The S&P 500 spans technology, financial services, healthcare, consumer staples, industrials, energy, real estate, utilities, and more. Even within the same economic environment, these sectors may behave differently. Tech might underperform when rising interest rates make growth stocks less appealing, but consumer staples or healthcare might hold up better. That spread helps mitigate catastrophic losses from any one sector.

• Balanced Exposure to Tech: Keep in mind, you’re not missing out on big tech by investing in the S&P 500. Apple, Microsoft, Amazon, Alphabet, Meta, and several other giants make up a significant portion of the S&P 500 as well. The key difference is that their combined weight is less concentrated, so your portfolio is not fully beholden to their fate. You still benefit from their successes, just with a bit more cushion if they hit a rough patch.

• Long-Term Historical Performance: Over time, the S&P 500 has delivered a reliable stream of returns—typically around 10% annualized over many decades (though that’s an average and not a guarantee). During certain tech booms, the Nasdaq can outpace it, but the S&P 500’s track record is nothing to scoff at, especially when you consider its risk-adjusted performance.

• Institutional Familiarity and Options: Many retirement plans, especially in the United States, default to or heavily feature S&P 500 index funds. It’s one of the most widely followed benchmarks on the planet. That familiarity contributes to its relative stability, because it means the S&P 500 remains a go-to reference for fund managers, pension funds, and individual investors alike.

• Psychological Resilience: This point is more intangible but arguably the most important: the S&P 500’s broader composition helps you stay invested. It’s easier to stomach a 30% drawdown than a 60% or 70% one. Staying invested is critical, because the biggest gains often occur in the early days of a market recovery, days that many panicked sellers miss entirely if they bail out.

Addressing Common Counterarguments

“But Tom, the Nasdaq returns are historically higher!”

I hear you. There have been stretches—especially in recent bull runs—where the Nasdaq absolutely trounces the S&P 500. However, those returns also come with bigger drawdowns. Higher reward, higher risk. If you can handle the extreme volatility and are truly in it for the ultra long haul, you might choose to overweight the Nasdaq or put some portion of your portfolio in it. But for the average investor seeking a reliable core, I still advocate the S&P 500.

“Aren’t we going to miss the next tech revolution?”

Remember, the S&P 500 still holds many leaders in cutting-edge technology, including the biggest players in software, cloud computing, e-commerce, AI, and so on. Moreover, new entrants to the S&P 500 frequently reflect shifts in the economy’s structure. As big new tech players grow and smaller or fading companies exit, the S&P 500 updates its composition. It’s dynamic, not static.

“Isn’t the S&P 500 boring?”

I sometimes joke that “boring is beautiful.” Investing doesn’t have to be adrenaline-filled. In fact, if you’re feeling adrenalized every day, you’re probably taking on too much risk or gambling rather than investing. The S&P 500 allows you to let the market do its work over time, freeing you from the need to constantly check prices or stay up late agonizing over what the Fed might do next quarter.

My Investing Philosophy in a Nutshell

Let me outline how I blend these perspectives into a cohesive approach:

• Core Model: I keep a significant portion of my portfolio in a broad index—namely, the S&P 500. This represents the “core,” the anchor that doesn’t change much. Around that, I might have “satellites” such as individual tech stocks that I’ve researched extensively.

• Regular Contributions (Dollar-Cost Averaging): Rather than trying to time the market, I believe in a steady rhythm of contributions—weekly, monthly, or quarterly. This approach, often called dollar-cost averaging, helps to mitigate the effects of short-term volatility. When prices drop, you buy more shares; when they rise, you buy fewer. Over decades, it averages out.

• Rebalancing: If one of my satellite positions (let’s say a high-flying tech stock) doubles or triples, it may start taking up a bigger piece of my overall portfolio than I’m comfortable with. Periodic rebalancing can maintain my original risk profile.

• Focus on Fundamentals and Valuations: Whenever I do pick individual stocks, I don’t rely on hype. I examine their business models, profitability or path to profitability, the size of their addressable market, their competitive advantages, and their leadership’s track record. If I’m not confident I can thoroughly understand a particular sector or company, I simply avoid it.

• Long Term Perspective: Perhaps the most critical pillar is patience. My mindset is that I’m willing to ride out whatever short-term drama unfolds because I trust that over 10, 20, or 30 years, the market rewards consistent, disciplined investment.

Lessons from Past Market Bubbles and Crashes

I’m old enough to remember the frenzy of the late 1990s, when just about every company that appended “.com” to its name soared on speculation alone. We’ve seen echoes of that in other hype cycles since then, and while technology remains a transformative force, it’s not immune to valuation bubbles. When fear hits, or fundamentals fail to keep up with lofty expectations, valuations can collapse in a hurry.

Crucially, investors who were overexposed to these hype cycles often ended up exiting at the worst possible moments. Some sold out during the dot-com crash or the Great Recession and never reentered, missing out on a historic bull run that followed. It’s a harsh reality that emotional responses often sabotage long-term performance.

Now, that’s not to say the S&P 500 can’t be overvalued or can’t decline. It absolutely can. But historically, because it represents so many diverse sectors, it tends to exhibit less radical booms and busts than a tech-concentrated index. And it’s those extreme swings that trigger emotional mistakes for a lot of people.

The Regulatory Angle (and Why It Matters)

If you follow the details of retirement plans or certain global regulations, you might notice that many governmental bodies encourage or even mandate that large retirement funds or pension schemes offer the S&P 500 or another broad-based index as a default option. In some jurisdictions, there are restrictions on how much of a pension or retirement fund can be allocated to narrower or more volatile indices like the Nasdaq-100.

While I’m not always a fan of sweeping regulations, it’s telling that regulators themselves show a preference for the S&P 500 in many cases. They recognize the diversification and broad-based stability it provides. One could argue that this widespread adoption of the S&P 500 as a core investment choice also helps keep it relatively stable, as so many institutional funds funnel money into it regularly.

Common Misconceptions About the S&P 500

• “It’s just the top 500 American companies.”
  Yes, but remember, many of these companies are multinational. They derive revenue from all over the globe. So, you are getting some international exposure implicitly.

• “You’ll underperform the ‘hot stocks.’”
  In some particular stretches, absolutely—you might underperform a hot sector or a group of surging tech names. But you’ll also avoid gut-wrenching collapses if those hot stocks turn sour. Over many years, that can make all the difference.

• “If I want growth, I can’t use the S&P 500.”
  Actually, many S&P 500 companies still post impressive growth. Several tech firms within the index have strong growth profiles. And other sectors can also show robust expansion under favorable economic conditions (e.g., healthcare or consumer goods during certain cycles).

Crafting a Sustainable Strategy

At the end of the day, successful investing isn’t about picking the single best-performing asset class or index ex post facto—that is, after we already know which soared the highest in a given window. It’s about aligning your portfolio with your risk tolerance, your financial goals, and your emotional makeup so you can stay invested throughout market cycles.

That last part, staying invested, is underrated. Even a well-diversified index can’t help you if you jump out at the bottom of a bear market. My entire philosophy aims to reduce the chance that I’ll make a decision out of panic or short-term thinking. I want the bulk of my portfolio to be in something that I believe in so strongly, and that’s diversified enough, that I can hold it through thick and thin.

Because I appreciate the power of technology, I might dedicate a certain percentage—say, 10–20%—to narrower tech-focused positions, whether that’s the Nasdaq-100, certain thematic ETFs, or carefully chosen individual stocks. But that remains separate from my “broad market index” portion, which I typically anchor around the S&P 500.

How I Handle Market Volatility

I want to offer a bit more color on dealing with volatility. It’s easy to say we should “ignore market swings,” but when you see your account dropping by tens or hundreds of thousands of dollars, it can stir up very real anxieties.

• Acknowledge the Emotional Response: I don’t pretend to be a robot. When the market tanks, I feel that jolt in my gut just like anyone else. The difference is that over the years, I’ve trained myself to question whether that fear is rational or whether it’s a knee-jerk reaction.

• Revisit the Long-Term Thesis: If I own a broad index for the next 20 years, has anything fundamentally changed that invalidates that entire premise? Usually, the answer is “no.” If it’s a short-term event—a recession, a war scare, a temporary shift in consumer sentiment—I know from history that markets have always found a way to adapt. That helps me stay put.

• Identify Opportunities: Sometimes, if my cash flow and situation allow, I’ll use market downturns to buy more shares of the core index. This is how you turn volatility from an enemy into an ally: you acquire more ownership in great businesses (collectively, via an index) at cheaper prices.

• Keep Perspective: I remind myself that the stock market has weathered world wars, pandemics, the Great Depression, multiple recessions, oil crises, and bursting bubbles. Yet, over time, it has tended to reward patient investors. The S&P 500 is a testament to the resilience of the diversified U.S. corporate sector.

Potential Future Surprises

“Tom, what about the future? Could the Nasdaq’s tech dominance become even stronger, leaving the S&P 500 in the dust?” It’s a valid question. None of us has a crystal ball. Tech might keep forging ahead in the coming decades, or we might see a series of regulatory clampdowns, tax changes, or even new technology disrupt the disruptors. The pace of change in tech is relentless.

But that’s exactly my point: the future is uncertain. It’s easy to look backward and see that the Nasdaq outperformed in certain periods, or that the S&P 500 was more stable. We can form hypotheses about the next 10 or 20 years, but we don’t know which new risks or macro shifts might appear. That is precisely why broad diversification is so powerful—it’s like buying a stake in progress itself, however it manifests.

The S&P 500 adjusts as the economy transforms. Companies that shrink or lag drop out of the index; those on the rise enter it. If technology continues to reign supreme, well, many of those flourishing tech names are or will become a substantial part of the S&P 500 anyway. Meanwhile, if some new wave of “old economy” sectors roars back, you’re covered there too.

My Final Thoughts

I’m not anti-Nasdaq. Let me repeat that in bold letters: I am not anti-Nasdaq. I appreciate the innovation and explosive growth possibilities it offers. What I am, however, is a realist when it comes to risk and volatility, and an advocate for matching your investments to your emotional and financial capacity to endure downturns.

If someone insists they can keep a large portion of their portfolio in the Nasdaq long-term without panicking when inevitable downturns occur, I’ll wish them well—maybe they’ll do great, maybe they’ll post fantastic returns. But in my personal framework, I’d rather have the S&P 500 serve as my principal equity holding, and then add a “tech tilt” elsewhere if I want more exposure to that area.

At the end of the day, the market isn’t about finding the single best performer in hindsight; it’s about staying in the game with a strategy that lets you sleep at night. The S&P 500 gives me that balance. It has enough exposure to cutting-edge technology to keep me engaged and enough diversification to help me remain calm in the storm.

That calmness, that ability to remain invested and to keep adding money during dips, is what I truly believe drives long-term wealth creation. And that, in essence, is why I favor the S&P 500 over the Nasdaq for a broad market index.

If you’re reading this and thinking, “I’m not sure which path is right for me,” my advice is to evaluate your real risk tolerance (not the one you imagine in a bull market) and ask yourself how you would or did react in a severe downturn. If you can’t confidently say you’d stay invested with a high-tech concentration, you may be better served by something broader and more stable, like the S&P 500.

In Closing

I hope this has given you deeper insight into the why behind my stance. This isn’t about picking winners and losers on a yearly basis. It’s about constructing a portfolio that harnesses economic growth while shielding you from the worst of your own emotional impulses. The S&P 500, in my view, accomplishes that elegantly.

The Nasdaq can be a powerful ingredient in the mix—especially if you fully understand and accept the ups and downs of a tech-weighted index—but for a solid foundation, I put my faith in the S&P 500. And that’s why, no matter how many times people ask me, “But Tom, the Nasdaq had incredible returns this year—shouldn’t we just go 100% Nasdaq?” my answer remains the same: I’d rather anchor myself in an index that gives me the confidence to hold on, come what may.

Because at the end of the day, the best strategy is the one you can stick with long enough for it to work.

Thank you for reading, and as always, I encourage you to stay curious, question everything, and invest not just with your wallet, but with clear eyes and a steady hand.
