You have seen this headline before: "Nasdaq hits record high."
Or maybe this one: "Nasdaq drops 3% on tariff fears."
The Nasdaq is one of the most talked about parts of the stock market. But most people who hear about it every day still do not know what it is - or how to invest in it.
A Nasdaq index fund is one of the easiest ways to get a stake in the biggest tech companies in the world - all in one shot.
This article covers what the Nasdaq is, how a Nasdaq index fund works, the types of funds that track it, and how to pick the right one for your money. That includes what fees to watch and how to research any fund before you invest.

What Is the Nasdaq?
First - there are two things called "Nasdaq" and they are not the same.
The Nasdaq Stock Exchange is a market where public companies list their shares for trading. It is one of two major stock markets in the U.S., along with the New York Stock Exchange.
The Nasdaq 100 is a stock market index. An index is just a way to track a group of companies.
The Nasdaq 100 tracks the 100 biggest non-bank companies by market cap - which is the total value of all their shares.
So the Nasdaq 100 does not include banks or insurance firms. It is mostly made up of tech companies like Apple, Microsoft, Amazon, Nvidia, and Meta.
That is why when you hear "the Nasdaq is up" or "the Nasdaq is down," it usually shows how big tech is doing that day. For a closer look at how the Nasdaq compares to other major indexes, check out our guide on what the S&P 500 is.
How Does a Nasdaq Index Fund Work?
A fund is a basket of stocks. Instead of buying shares in one company, you buy into a group of companies all at once.
A Nasdaq index fund is a fund that tracks the Nasdaq 100. When you invest in one, your money gets spread across all 100 companies in that index.
Here is why that matters. If one company in the fund has a bad quarter, the other 99 can help balance it out.
You get a stake in the biggest names in tech without having to pick winners on your own. When you buy shares of a fund, you become a shareholder in all of the companies inside it.
Index funds are run by a computer, not a person. The system makes sure the fund holds the same companies as the Nasdaq 100 index. If a company drops out of the index, the fund adjusts.
Because a computer does the work instead of a money manager, the fees are much lower. For a deeper look at how to invest in the Nasdaq without picking a single stock, we have a full guide on that too.
Nasdaq Index Fund vs. ETF vs. Mutual Fund
There are three main types of funds that can give you access to the Nasdaq 100. They hold the same types of companies, but they work a bit different. We have a full breakdown of the differences in our article on ETF vs mutual fund vs index fund.
Index funds are run by a computer. They trade once per day. Fees are low.
Mutual funds are run by a money manager - a real person. They also trade once per day. Fees are higher because you are paying that person to make choices.
ETFs - or exchange-traded funds - trade just like a stock. You can buy and sell them all day long, as many times as you want. They can be run by a person or a computer. For a closer look at how ETFs and mutual funds stack up, we cover that in detail.
One of the most well-known Nasdaq ETFs is QQQ. It gives you a stake in the Nasdaq 100 and trades just like any other stock.
The big takeaway: all three fund types can give you access to the Nasdaq. The gap comes down to fees, how often you can trade, and who is running it.
How To Pick the Best Nasdaq Index Fund
Not all funds are the same - even if they track the same index. Here is a simple way to pick the right one.
Question 1: Who runs the fund?
Start with the fund manager. The biggest names include Vanguard, Fidelity, Charles Schwab, and SPDR (State Street). These are firms that have been around for decades and manage trillions of dollars.
Why does that matter? When the market drops, you want to know your fund is solid. Funds are not FDIC insured like a bank account.
So the size and track record of the company behind your fund matters - a lot. You can open an account with most of these firms through an online stock broker or brokerage app.
A good rule of thumb: if the fund manager has been around for a long time and manages a lot of money, that is a green flag.
Question 2: What is in the fund?
This is where the CDAA method comes in. It is a simple way to break down any fund.
- Companies: What companies is the fund putting money into? A Nasdaq index fund should hold the same companies as the Nasdaq 100 index. Check the holdings to make sure they match.
- Dollars: How much money is in the fund? This is called assets under management, or AUM. For index funds, look for at least $1 billion in AUM. If a fund does not have much money in it, it can be harder to sell your shares when you need to.
- Asset Allocation: How is the money split across companies? Even two funds that track the same index can weight companies in different ways. Check how much of the fund goes to the top names versus the rest.
You can find all of this on the fund's website or in the prospectus - a legal document the SEC requires every fund to share. It includes holdings, past results, risks, and more. The fund's net asset value (NAV) should also be easy to find on its webpage.
Question 3: What does it cost?
Every fund charges a fee called an expense ratio. It is a small cut of your total investment, taken out each year.
It sounds tiny. But over time, it adds up fast.
Here is the math: if you put $1,000 a month into a fund for 40 years at a 12% return with a 0.09% expense ratio, that small fee would cost you over $300,000 in total. You would still end up with over $11 million - but the fund manager takes a big cut just for running your money.
Funds run by a computer usually charge under 0.4%. Funds run by a person can charge 1% or more.
A 1% fee can eat up to 28% of your total portfolio over a full career of investing. If you are figuring out how much to invest in stocks, understanding this fee is a key part of the math.
Always check the expense ratio before you invest. Then ask: do the returns make this fee worth it?
How To Start Investing in a Nasdaq Index Fund
Once you have picked a fund, the next step is to build a system. This is the core idea behind passive investing - setting up a plan and letting it run.
Many investors use a plan called dollar cost averaging. Instead of trying to time the market, you invest a set amount at set times - weekly, every two weeks, or once a month.
Here is what that looks like. Say you invest $100 a month into a Nasdaq index fund.
Some months the market is high and your $100 buys fewer shares. Other months the market dips and your $100 buys more. Over time, you buy at an average price - which smooths out the swings.
The big win here is that it takes emotion out of it. You are not sitting there every day asking "is now the right time?" Knowing when to buy a stock - or a fund - is one of the hardest parts of investing. Dollar cost averaging removes that pressure.
You made the choice once. Then your money goes to work on its own.
Most brokerage apps let you set up auto-investing in just a few minutes. Over decades, this approach can help you retire a millionaire.
Risks To Know With The Nasdaq
A Nasdaq index fund is heavy on tech. That is great when tech is booming - but it also means more risk when tech pulls back. Tech stocks tend to be among the most volatile stocks on the market.
In 2025, when major tariff policies were put in place, the Nasdaq dropped into bear market range. Big tech stocks lost a lot of value in just days.
The companies did not get worse overnight - but the market was pricing in fear. Understanding how to invest during a recession or a downturn is what separates long-term investors from those who panic sell.
There is risk in any fund. You are never sure to make money. In fact, you will likely lose money at some point.
The key is knowing what you own and having the patience to ride out the dips.
Nasdaq Index Funds - What's Worth Knowing
A Nasdaq index fund gives you a simple way to invest in the biggest tech and growth companies in the world. The right fund depends on who runs it, what is in it, and what it costs.
Start by looking at funds from well-known firms. Use the CDAA method to compare them. Check the expense ratio.
Then build a system - set up auto-investing, stay steady, and give your money time to grow.
