What Is The S&P 500?

The Standard & Poor’s 500 Index is a market value weighted index of the 500 largest publicly traded companies in the United States.

Market value weighted simply means that the larger a company is, the more weight it will carry in the index. So when you invest, a large portion of your money goes into stocks like Microsoft, Apple, NVIDIA, Amazon and Meta.

S&P 500

Finviz has a heat map that shows you a visual of this in action - the larger the square is, the more of your money gets allocated there.

Now the S&P 500 was launched in 1957, which predates many of the companies that are included in the index today. To adjust for this, the 500 companies included within the index change over time - based on what US companies are the most valuable.

The S&P 500 is the most widely accepted benchmark for tracking the US stock market, and because it has been around for so long, we have decades of historical performance to look back on.

Why Invest In The S&P 500?

So why do people invest in the S&P 500?

Well the very reason for investing in the first place is to protect your buying power from inflation as well as grow the value of your money.

Inflation has historically been around 2% annually, but since the pandemic and the stimulus money that entered the economy, it has been elevated. This makes investing all the more important, as idle cash is losing purchasing power at a faster rate than it has in the last 40 years or so.

US Inflation Rate

In addition, the S&P 500 provides you with broad diversification across a large portion of the US economy. When you invest in this index, your money is spread out across all of these different sectors and industries.

This gives you exposure to all different segments of the US economy. If one particular company or segment takes a nosedive, the rest of what you own will help to offset that.

You also have the benefit of being able to follow a “set it and forget it” approach. You can fully automate this investing strategy, and then spend your time doing the things you enjoy.

S&P 500 ETFs

The most common method for investing in the S&P 500 is through an ETF or exchange traded fund.

For this example, we will be using the Vanguard S&P 500 ETF which trades under the symbol "VOO."

VOO Vanguard S&P 500

An ETF is simply an index fund that is split up into shares that then trade on an exchange just like a stock. And an index fund is a basket of stocks designed to track an underlying index as closely as possible. In this case, the index would be the S&P 500.

ETFs makes things a lot more flexible, allowing you to buy individual shares - and through Robinhood you can even buy fractional shares.

The minimum purchase amount for a fractional share on Robinhood is $1, so that means you can literally invest a buck into the S&P 500 using VOO.

Expense Ratio

Now every fund out there has an expense ratio associated with it, and this fee is used to pay the fund managers as well as other administrative costs.

The good thing about Vanguard is they have some of the most competitive fees in the industry.

VOO Expense Ratio

For VOO - that expense ratio comes in at 0.03% (which could change in the future) compared to an industry average of 0.79% as an expense ratio. The expense ratio is deducted from the fund’s returns, meaning you won’t see a separate charge for it—it’s built into the performance of the ETF.

That means if you invested $10,000 into VOO, you would pay $3 in annual expenses to Vanguard. This fee comes out of the fund itself, so you don’t have to pay it separately or anything like that.

VOO’s dividend yield fluctuates based on share price and quarterly dividend payments. Over the last 30 days, it has averaged 1.19%, but this rate is subject to change.

Now, let's dive into the steps to invest in the S&P 500 using Robinhood.

1. Open A Robinhood Account

The first step is to open a Robinhood account. Be sure to sign up through our link here to get a free stock worth up to $200 when you create a new account!

Once you've opened your account, you can move on to the next step which will take place within the Robinhood app.

2. Locate "VOO" In Robinhood App

The next step is going to be locating the Vanguard S&P 500 ETF within the Robinhood app.

Robinhood S&P 500 investing

Here's how to do that:

  1. Open the Robinhood app
  2. Click on the search icon in the top right
  3. Type in "VOO"
  4. Click on the top result in the search

3. Open Trade Window

Once you are on the designated screen for VOO, the next step is to open the trade window.

Robinhood S&P 500 investing steps

Here's how:

  1. Click on the Trade button at the bottom right
  2. Select Buy
  3. Enter the dollar value you would like to invest using fractional shares (if you want to buy whole shares, you can change this with the dropdown in the top right)
  4. Click on the Review button 
  5. Swipe up to submit the order after checking the details over

4. Track Your S&P 500 Investment

Once you've made your investment into the S&P 500 using Robinhood, you can track your investment performance within the app.

All you have to do is click on VOO from the list of investments within your Robinhood portfolio.

Robinhood VOO

From here, you can scroll down on the ETF page to view your investment performance.

This will be below the section labeled Your position.

Robinhood SP 500 investment

For example, this fractional share investment I made into the S&P 500 through the Vanguard ETF has experienced a total return of 9.69%. 

The S&P 500 goes up and down, but over the long run, it has a long history of generating positive returns. Your best bet is to ride out the bad times in the short term if the market drops, as it's really the long term performance that matters.

Dollar Cost Averaging

Robinhood offers a recurring investment option for those looking to invest a set amount of money on a recurring schedule. This can be helpful with long term ETF investing, as it allows you to deploy a popular strategy called dollar cost averaging.

Dollar cost averaging (DCA) is a simple investment strategy where you invest a fixed amount of money at regular intervals, regardless of the price of the investment.

By spreading your investments over time, you reduce the risk of investing a large amount of money at the wrong time. In addition, you don’t have to worry about timing the market or deciding the best time to invest.

Dollar cost averaging allows you to pay the market average for shares over time.

Example

Let's say you were investing $100 a month on a recurring schedule. This would be following the strategy of dollar cost averaging.

Here's what this might look like:

  • January: Invest $100 at $10 per share = 10 shares
  • February: Invest $100 at $8 per share = 12.5 shares
  • March: Invest $100 at $12 per share = 8.33 shares

Over three months, you’ve invested $300 and purchased 30.83 shares. The average cost per share would be approximately $9.73.

If you had instead invested all $300 at once when the price was $12 per share, your average cost per share would be $12. This is a prime example of how dollar cost averaging can help you lower your average cost per share (or cost basis) over time.

This example is simplified. In reality, stock prices fluctuate due to macroeconomic factors, earnings reports, and investor sentiment. Over long periods, dollar-cost averaging tends to reduce volatility but may not always outperform lump-sum investing.

Robinhood Recurring Investments

If you want to put the strategy of dollar cost averaging into action, you can do so using the recurring investment feature within Robinhood.

Here's how to set it up:

  1. Open the Robinhood app
  2. Click on the search icon in the top right
  3. Type in "VOO"
  4. Click on the top result in the search
  5. Click on the Trade button
  6. Select Buy
  7. In the top right, click on the dropdown menu
  8. Scroll down to Conditional orders
  9. Select Recurring investment

This will allow you to choose the frequency that you invest the dollar amount you specify into VOO. The options are every market day, weekly, every 2 weeks or every month.

Robinhood recurring investment

Orders will automatically be placed on your behalf between 11 am EST and market close.

S&P 500 Investing Mistakes

While investing in the S&P 500 can be a great long-term strategy, there are a few common pitfalls to watch out for.

1. Misunderstanding Lump-Sum Investing vs. Dollar-Cost Averaging

Lump-sum investing can feel risky, especially if the market declines shortly after you invest. However, historical data suggests that investing a lump sum immediately has outperformed dollar-cost averaging (DCA) about two-thirds of the time. This is because markets tend to rise over the long term, meaning that waiting to invest often results in missed gains.

That said, if you’re concerned about short-term volatility, dollar-cost averaging—investing smaller amounts at regular intervals—can help reduce the risk of entering the market at a high point. This approach can provide peace of mind and ensure you stay committed to your investing plan.

2. Reacting Emotionally to Market Volatility

One of the biggest mistakes investors make is panic selling during market downturns. The S&P 500 has seen multiple bear markets and crashes, but over the long run, it has historically recovered and continued to grow. While short-term losses can be unsettling, selling during a downturn locks in losses and prevents you from benefiting from the market’s eventual rebound.

Instead of fearing downturns, consider viewing them as buying opportunities. When stock prices drop, you can accumulate more shares at lower prices, improving your long-term returns.

3. Ignoring Investment Fees

Not all S&P 500 ETFs are created equal. While low-cost ETFs like Vanguard’s VOO (0.03% expense ratio) help maximize returns, some funds come with higher management fees that eat into your gains over time. Always compare expense ratios and trading costs before choosing an investment, as these fees can significantly impact your returns over decades.

By keeping these pitfalls in mind and maintaining a disciplined investing approach, you’ll be better positioned to build wealth through the S&P 500 while avoiding costly mistakes.
