Technology stocks have been a hot topic among investors for some time. More recently and throughout 2020, the rise of big tech as fueled by the COVID-19 pandemic has led to even more interest in the sector.

How could you ignore gains like what we have seen from Apple (AAPL), (AMZN), and Alphabet (GOOG), who saw gains in 2020 of nearly 80%, 70%, and 30%, respectively? Considering the average return in the stock market is around 10% annually, these returns are mind-blowing.

But what exactly are tech stocks? And should you invest in them?

What Are Tech Stocks?

Tech stocks, a shortened term for technology stocks, represent companies within the technology sector. These companies lead the charge in terms of innovation, looking for answers to some of the biggest challenges consumers face today. For example:

You own shares of Apple, Amazon, Tesla. Why not Banksy or Andy Warhol? Their works’ value doesn’t rise and fall with the stock market. And they’re a lot cooler than Jeff Bezos.

  • Autonomous Vehicles. One of the hottest new trends in technology, several companies are racing to produce safe autonomous, or driverless, vehicles. The idea is that by automating the driving process, human error is taken out of the equation, leading to fewer traffic-related injuries and reducing the financial burden car accidents have on consumers and the economy as a whole.
  • Medical Innovation. Several biotechnology companies are developing new therapeutic options for ailments that were once considered untreatable. Just 20 years ago, AIDS was considered a death sentence. Thanks to cutting edge technology and medical innovation, it is a manageable condition today.
  • Communication. Due to the coronavirus pandemic, there has been a rise in video conference technology that allows patients to communicate with doctors, family members to keep in touch, and co-workers to discuss their next moves. Several companies offer technology that facilitates video conferencing.

That’s just scratching the surface of all the tech sector has to offer.

No matter what you’re doing, from driving to watching television or even walking down the street, technology has likely made it a better experience in one way or another. Investing in tech stocks gives investors the ability to gain financially from this improvement as technological innovation continues.

3. E-Commerce

Another major area of the tech sector is e-commerce. If it weren’t for the technological innovation that drove the development of content management systems, digital payment processing, and the servers that tie it all together, you would still have to drive to the store and hand over cash to buy everything you wanted.

When you think of tech companies, it’s not likely that your mind will go to medicine. However, some of the most impressive tech stocks on Wall Street use technology as a way to address some of the world’s most pressing medical conditions. These companies are known as biotechnology or biotech companies. Some of the best-known companies in the biotech space include:

  • Novo Nordisk (NVO). Novo Nordisk is one of the largest biotech companies in the world.

Without semiconductors, the massive servers that host the world’s largest websites and the computers and mobile devices used to access them simply wouldn’t exist.

Some of the major players in the semiconductor industry include:

Pros and Cons of Investing in Tech Stocks

Investing in tech stocks can be an exciting concept. Not only is it enjoyable to explore new technologies during your research into compelling investment opportunities, but the sector is known for generating significant gains when the right moves are made.

However, it’s not all sunshine and rainbows. Like any other sector, the technology sector has its own skeletons in the closet. For example, heavy volatility and a cyclical nature add to the risks involved in investing in the space. Here are the pros and cons you should consider before diving in:

Pros of Tech Stocks

There are plenty of perks to investing in the tech sector. Some of the most significant include:

  1. Invest in What You Enjoy. Technology is an enjoyable topic for the majority of consumers, which makes investing in tech stocks fun. Successful investing involves detailed research. When you enjoy the topic of research, you’re more likely to do the intense research required to make educated investing decisions.
  2. Tremendous Growth Potential. Innovative technologies have the potential to lead to tremendous gains in value. There are three names that gained substantially in 2020 at the beginning of this article but there were several companies across the sector that saw similar gains. Educated investments in the tech sector have the potential to lead to significant gains in your investment portfolio.
  3. Options for Diversification. The tech industry is massive with several subcategories. Moreover, the industry covers a wide range of companies in different stages of business with different market caps. As such, there is plenty of room for diversification within the sector.

Cons of Tech Stocks

Although there are plenty of reasons to get excited about tech stocks, every rose has its thorns, and the tech category isn’t without them. Here are some drawbacks you should consider before investing in the space:

  1. High Valuations. Compared to other sectors, the tech sector is known for incredibly high valuations. In most cases, investors justify these valuations by pointing to the future value of innovative technology. Nonetheless, buying overvalued companies can be dangerous and lead to significant losses.
  2. High Volatility. Any time there’s potential for high short-term gains, there’s also likely quite a bit of volatility in the space. That is true among many tech stocks. Volatility is a measure of the fluctuations that take place in the prices of stocks. With high levels of volatility comes a certain level of difficulty when it comes to picking the best times for entrances into and exits out of these stocks.
  3. Tech Isn’t Known for Dividends. Although some companies in the technology industry do pay dividends, the vast majority of tech companies don’t. Most tech companies hold onto their profits to fuel research and development and continued innovation rather than sharing them directly with investors, and for good reason. Even a company that’s seemingly on top of the world in the tech industry will fall from its throne should it stop innovating. Just take a look at what happened to BlackBerry when competing smartphone companies like Apple stepped into the industry. If you’re looking for compelling dividends, tech isn’t where you’re likely to find them.

Where to Find Tech Stocks

Tech stocks can be found at both of the major US stock exchanges, the Nasdaq and the New York Stock Exchange (NYSE). Nonetheless, the vast majority of quality tech companies you’ll find will be listed on the tech-heavy Nasdaq.

You’ll also find plenty of tech stocks on the over-the-counter (OTC) market. However, if you’re a beginner, you’ll want to stay away from these stocks. The OTC market is filled with penny stocks that, for one reason or another, do not qualify for listing on the Nasdaq or NYSE. These stocks may seem promising, but they generally come with the following major risks:

  • Reporting. OTC stocks are often nonreporting or underreporting. This means the financial data surrounding these stocks is generally outdated or incomplete.
  • Speculation. The vast majority of stocks traded on the OTC market have business models that haven’t quite been proven. As such, these stocks are highly speculative bets, only adding to the risk.
  • Capital Risk. Most stocks on the OTC market are undercapitalized and will need to reach capital markets to raise funds at some point. When this happens, these companies will generally do so through the sale of newly-issued shares, which is like slicing more pieces of the pie — including a sliver from your piece — causing existing shares to shrink in a process known as dilution.
  • Volatility. Finally, while the tech sector is one that’s known for heavy volatility, that volatility is exacerbated when playing in penny stock territory, only serving to expand the risk.

Tech-Focused ETFs Are a Compelling Option for Beginners

If you’re a beginner investor or you simply don’t have the time to do the research it takes to pick stocks individually, you may want to look toward Nasdaq index funds, exchange-traded funds (ETFs), and mutual funds.

Nasdaq index funds are designed to mimic the movement of the tech-heavy Nasdaq composite index. So naturally, these are highly diversified choices to give you exposure to the tech sector. However, there are also plenty of ETFs and mutual funds that are geared exclusively toward the tech sector or subsectors. Some of the most popular include:

  • Technology Select Sector SPDR Fund (XLK). The Technology Select Sector SPDR Fund is a highly diversified large-cap ETF designed to track the tech sector as a whole. The largest holdings in the ETF include Apple, Microsoft, and NVIDIA.
  • Vanguard Information Technology Index Fund ETF (VGT). As its name suggests, the Vanguard Information Technology Index Fund ETF is an ETF that tracks an index of information technology companies. The ETF consists of small-, mid-, and large-cap companies and takes a heavily diversified approach to wider tech sector exposure.
  • Fidelity Select IT Services Portfolio (FBSOX). Finally, Fidelity Select IT Services Portfolio is a highly diversified mutual fund. At least 80% of the fund’s assets are invested in companies that provide IT services. The fund’s primary objective is capital appreciation, seeking to invest in companies with high potential for future growth.

Final Word

Investing in the tech sector can be incredibly lucrative. However, the wrong moves in the sector can also lead to significant losses. As such, before making any investment in the space, it’s important to do your research.

When looking for companies to invest in, look for companies that have a proven track record of innovation and a long-standing ability to stay on top of their subcategories. Also, pay close attention to valuations. Although tech stocks often carry high valuations, it’s important to make sure that the price you pay is on par with the rest of the sector.

When you do your research and make wise moves in the space, there are few other areas where you’ll find opportunities that are as impressive in terms of growth.
