Introducing S&P500

S&P 500 is an index that tracks the performance of 500 largest US companies. In this article I’ll tell you how to invest in it, what advantages and disadvantages it has, and what are the alternatives to it, if you don’t want to hold 490 companies that you don’t know, but also not spend too much time stock-picking.  

Why is the S&P 500 a good asset?

  1. Easy. You don’t need to spend hours researching stocks or comparing financial metrics, you just buy the whole market with this index. Like a box of chocolates with different flavours. Also, the composition is not fixed forever: companies come and go. For example, Tesla was added to the S&P in 2020 and kicked out Apartment Investment and Management. Fortunately for you, you won’t need to buy extra Tesla to maintain the same index, it’s automatically rebalanced. 
  2. Good returns. Over the past 30 years, the S&P 500 index has delivered a compound average annual growth rate of 10.7% per year. It is the main benchmark for the rest of the market, and hedge fund managers try to outperform it (spoiler, unsuccessfully). Over a 20-year period, about 90% of index funds tracking companies of all sizes outperformed their active counterparts. Even over three years more than half of index funds did better, according to a 2020 report from the S&P Indices Versus Active (SPIVA).
  3. Safe and diverse. Stocks go up and down all the time, new policies and macroeconomics affect sectors of the economy differently. It’s a guessing game what’s going to rise next. Should you invest more in biotech or consumer staples? Will a recession happen next year? You’ll never know until it’s too late, so the safe way would be to invest in the S&P because while some sectors might fall, others will grow. 
  4. Lower costs. Because there is less trading volume with passive investing, this brings the costs down for investors. The average expense ratio for passive mutual funds in 2020 was 0.06%; passive ETFs came in at 0.18% compared to range from .5% to 1.5% for actively managed funds.


Buying the S&P 500 is the epitome of passive investing. Passive investing is buying and holding stocks for a longer period of time. It’s like you bought an Apple share together with your first iPhone in 2014 and kept holding it. But you don’t even have to choose between Apple or Android, you buy both. Same here — you buy the whole market. 

Despite how sweet it sounds, here is one big disadvantage in SP500. Dispersed returns and sensitivity to macro economic events. Let me give you an example. If you’ve invested in apple 5 years ago, you would've grown your capital by 187%, whereas with S&P it’s 41%.

Because all companies perform differently. There are trendier sectors like Technology and more lagging like Utilities. So if you want to grow more, you can also bet on more trendy and specific topics like 3D printing by investing in TTF.

How to invest in the S&P 500?

  1. The most expensive way. If you have a million dollars, you can just buy one stock of each company, but obviously that’s a lot of money and hassle - to have 500 individual companies in the portfolio is endless scrolling. You don’t want this.
  2. Buy S&P 500 ETFs in your brokerage accounts. An ETF is an exchange-traded fund, it’s like a basket of securities. The largest ones are SPDR S&P 500 ETF Trust, iShares Core S&P 500 ETF and Vanguard S&P 500 ETF. 
  3. All 500 companies can be divided into 11 sectors based on size as follows: Information Technology, Health Care, Financials, Consumer Discretionary, Communication Services, Industrials, Consumer Staples, Energy, Utilities, Real Estate, and Materials. So if you want to have broad diversification but don’t want to invest in particular sectors, like Utilities or Materials, then you can buy the sectors you like as thematic ETFs. Such as Financial Select Sector SPDR (XLF) or Technology Select Sector SPDR Fund (XLK).
  4. Or even better, you can invest more precisely in what you believe in and what you want to support. Not just invest in the whole Technology sector and companies most of which you don’t know, but specifically in AR/VR technology, or specifically in Copper mining companies. This is available through TTFs, model portfolios of 10-15 stocks made by professionals. And you can buy them in Gainy in one-click. 

To sum up, there is a saying

There is a way to get rich fast, there is a way to get rich for sure.

So buying S&P500 is a way to become rich for sure. And later you can accelerate your growth with investing in individual stocks, or ETFs, or thematic TTFs.

because I want to check what my friend has just sent me
The company developed and maintains technological products and services, namely Snapchat, Spectacles, and Bitmoji. Snapchat is the third most popular app among millennials and gets high profits from ads on the platform. Since TikTok is not available to invest in yet, Facebook is boring, we see Snap as a good choice to diversify your portfolio. We don’t know what keeps those kids so glued to screens in Snapchat but if companies profit from it, we can get a share thanks to investing in their stocks.
because xBox brings us together with friends
Microsoft is the second biggest company on the market in terms of capitalization. Xbox, Skype, Windows Office 365 are all part of Microsoft business as well as it develops, licenses, and supports a wide range of software products and services, as well as designs and sells hardware. The company’s future is as bright as it’s past with all the money the company invests in disruptive tools like AI. Next time you plan to buy another game for the Xbox console, you might also consider buying a Microsoft stock which is not very expensive.
because we want schools to be cooler
So we packed peanut butter and jelly sandwiches for the kids, now it’s time to go to school. The K12 Inc. is an educational technology company. The company offers a private education program, software and education services built to teach online for preschool students up to grade 12 or K-12. The company’s earnings soared up after the pandemic because we came to realise that online learning is not far in the future and may continue the trend.
because we like to treat our pets and ourselves, too
The American manufacturer of supermarket food JM Smucker Co also operates a pet food business including brands such as Milk-Bone and Meow Mix. It’s also the producer of the peanut butter JIF, kid’s all-time favorite filling. The company offers a 2.96% dividend yield and in the third quarter reported a 7% increase in net sales.
because we love playing games
If there is one game to teach you financial literacy - it’s Monopoly, which belongs to Hasbro, as well as unparalleled portfolio of approximately 1,500 brands including MAGIC: THE GATHERING, NERF, MY LITTLE PONY, TRANSFORMERS, PLAY-DOH, BABY ALIVE, DUNGEONS & DRAGONS, POWER RANGERS, PEPPA PIG and PJ MASKS, as well as premier partner brands. The company generates strong cash flows and pays regular dividends. The company’s business moves along the online trend and develops digital content in the form of TV shows, films, computer games.
because everyone has a favorite childhood hero
Disney is a widely diversified company which owns everything from toys to apparel, and books to video games: Disney Parks, ESPN channel, Pixar, Hulu and so much more. And now it bets on streaming services with Disney+ and threatens Netflix’s market share. The company revenue suffered a major drop last year due to closure of Disneylands, but has opened them in October and foresees a strong comeback.
