I recently read an interesting post from Freddy Smidlap that compared the performance of a total stock market index fund (VTSAX) to a Nasdaq 100 index fund (QQQ) from October 1, 2001 to October 1, 2018. The results were astounding. During that time period, QQQ rose by 402% compared to just 191% for VTSAX:

This made me curious, has the Nasdaq 100 always beaten a broad stock market index fund historically?
To answer this question, I compared historical returns for both the Nasdaq 100 and the S&P 500 since 1972. I realize that the S&P 500 only contains the largest 500 publicly traded companies in the U.S. and VTSAX contains every publicly traded company in the U.S., but these two indices have nearly identical annual returns:
Since I was able to easily find historical data for the S&P 500, I’ll be using it for this comparison instead of VTSAX.
The S&P 500 vs. The Nasdaq 100
Both the S&P 500 and the Nasdaq 100 track the performance of a basket of stocks, but the stocks they track are quite different:
S&P 500: tracks the 500 largest publicly traded companies in the U.S. and captures about 80% coverage of total U.S. market cap.
Nasdaq 100: tracks the 100 largest non-financial companies on the Nasdaq stock market. This group of stocks is heavily weighted in the technology sector, which typically experiences high growth and high volatility.
Here’s a look at the annual returns for the S&P 500 and the Nasdaq 10 since 1972:
- Since 1972, the Nasdaq 100 has experienced slightly higher annual returns (10.8%) than the S&P 500 (10.5%), but it has also experienced much higher volatility.
- During the bull markets, the Nasdaq 100 has crushed the S&P 500 (the 1990s and the post-2008 market).
- However, during bear markets, the S&P 500 has performed much better than the Nasdaq 100 (1973-1974, early 2000s, the 2008 financial crisis).
- The Nasdaq 100 beat the S&P 500 in 25 out of these 46 years (54% of years).
The Growth of a $10,000 Investment
Here is how a $10,000 investment in both the S&P 500 and the Nasdaq 100 would have grown from the start of 1972 to the end of 2017:
A $10,000 investment in an S&P 500 index fund would have grown to $1 million by the end of 2017 and an equivalent investment in a Nasdaq 100 index fund would have grown to about $1.14 million.
Growth of a Recurring Yearly $10,000 Investment
Here is how a recurring yearly $10,000 investment in both the S&P 500 and the Nasdaq 100 would have grown from the start of 1972 to the end of 2017:
A recurring yearly $10,000 investment in an S&P 500 index fund would have grown to $12.5 million by the end of 2017 and an equivalent investment in a Nasdaq 100 index fund would have grown to $18.4 million.
We’ve seen that the Nasdaq 100 outperformed the S&P 500 from 1972 to 2017, but what about during other time periods?
To answer this, I analyzed the average annual returns for these two indices during every 20-year period since 1972. Here are the results:
The Nasdaq 100 outperformed the S&P 500 in 18 out of the 27 20-year periods. It’s interesting to see that most of this out-performance has come in recent years, though.
It’s encouraging to see that the worst 20-year period for either index came from 1998 to 2017, in which the S&P 500 delivered 7.1% returns.
During the best 20-year period, the Nasdaq 100 delivered incredible 21.5% returns from 1980 to 1999.
So, which index is better? The unsatisfying answer: it depends.
We have seen that the Nasdaq 100 is much more volatile than the S&P 500, which makes sense considering it is heavily weighted in tech stocks. The Nasdaq 100 tends to perform better than the S&P 500 during bull markets, but worse during bear markets. For an investor who has decades ahead of them and is able to stomach this volatility, the Nasdaq 100 may be a better choice.
But just because the Nasdaq 100 has performed better in recent years doesn’t mean it will continue to do so. After all, the S&P 500 delivered better average annual returns in one-third of the 20-year periods since 1972.
It’s difficult to predict which index will deliver the best returns over the coming decades. The good news is that both indices have historically performed well over long investment horizons, so even if you pick the index that underperforms in the decades ahead you likely won’t regret your choice too much.
As an investor, it’s your job to keep your investment fees low, your savings rate high, and your patience jar full. No matter which index you choose to invest in, remain patient and resist the urge to time the market.
