The technology sector is vast, comprising gadget makers, software developers, wireless providers, streaming services, semiconductor companies, and cloud computing providers, to name just a few. Any company that sells a product or service heavily infused with technology likely belongs to the tech sector.

What are tech stocks?

Hardware Companies

These design and build devices such as:

  • Personal computers
  • Networking servers
  • Semiconductors
  • Smartphones
  • Fitness trackers
  • Smart speakers
  • Enterprise equipment, such as servers and networking gear

Software Companies

These design the software that runs on hardware, such as:

  • Operating systems
  • Databases
  • Cybersecurity software
  • Productivity software
  • Cloud computing providers
  • Artificial intelligence (AI)

Software companies are increasingly moving to a software-as-a-service model where customers buy a subscription to a program instead of a one-time license. The arrangement generates recurring revenue for the software company.

Semiconductor chips largely power the hardware. Semiconductor companies design and/or manufacture central processing units, graphics processing units, memory chips, and a wide variety of other chips that help to run today's devices.

Telecom companies that provide wireless services support the tech sector, but actually belong to the communications sector; so do the video streaming companies that provide easy access to high-quality content, and the cloud computing providers that power those streaming services.

The best tech stocks in 2024

Many of the most valuable companies in the world are technology companies. Here are three of the most dominant and largest tech stocks that investors should consider:

Microsoft (MSFT 0.34%) is a dominant software company known for its Windows PC operating system and Office productivity software. Microsoft is also the second-largest provider of cloud infrastructure.

Apple (AAPL 0.13%) makes the iPhone, iPad, and Mac computers. Intense customer loyalty ensures plenty of repeat customers, and a growing array of services makes Apple's ecosystem sticky.

Nvidia (NVDA -1.3%) is the premier manufacturer of semiconductors and advanced graphics processing units (GPUs) critical for not only gaming, but also for AI applications.

Did you know?

Alphabet (NASDAQ:GOOG) (NASDAQ:GOOGL), Amazon (NASDAQ:AMZN), and Meta Platforms (NASDAQ:META) are not technically tech stocks, despite often being lumped in with them.

These stocks actually belong to the communications (Meta and Alphabet) and consumer discretionary sectors (Amazon), despite their tech-heavy products and services.

The current market

Tech stocks in the current market

Technology stocks, as represented by the Technology Select Sector SPDR Fund (XLK -0.44%), which tracks S&P 500 technology stocks, have strongly outperformed throughout 2024.

The current market conditions have favored high-beta assets like tech stocks, which have enjoyed magnified returns in a generally bullish market environment. Most indexes are up, and technology stocks are increasingly sitting in the top holdings of the S&P 500 and Nasdaq-100.

Several macroeconomic factors have contributed to this strong performance. Inflation is cooling, which may signal the Federal Reserve Board to cut interest rates in the near future.

This trend has already been observed with central banks in Canada and the European Union initiating rate cuts.

Lower interest rates typically benefit growth stocks, including technology companies, as borrowing costs decrease and future earnings become more valuable.

Another significant trend driving tech stocks is the continued focus on artificial intelligence (AI). Multiple companies have committed to accelerating their AI spend or are in the process of commercializing more AI products. Here are a few highlights:

  • Nvidia: Nvidia has seen massive increases in quarterly revenue, largely driven by data center revenue for generative AI training and inference. The company declared a 10:1 stock split and increased its dividend by 150%. Nvidia's GPUs are at the forefront of the AI revolution, making it a key player in the tech sector.
  • Microsoft: Microsoft has reported double-digit growth in revenue, operating income, net income, and diluted earnings per share (EPS). This growth is largely attributed to the integration and usage of AI in its products, such as Copilot driving stronger AI integration, and increased usage of Microsoft Cloud, including Azure and Intelligent Cloud. Microsoft returned $8.4 billion to shareholders in the form of share repurchases and dividends in the third quarter of fiscal year 2024.
  • Apple: Apple launched its Vision Pro, authorized a $110 billion share buyback, and announced the 12th consecutive year of quarterly dividend hikes. Additionally, Apple introduced Apple Intelligence for iPhone, iPad, and Mac as a new smart assistant, further embedding AI into its ecosystem.

Analyzing tech stocks

How to analyze tech stocks

For mature tech companies that produce profits, the price-to-earnings ratio is a useful metric. Divide stock price by per-share earnings, and you get a multiple that tells you how highly the market values the company's current earnings. The higher the multiple, the more value the market is placing on future earnings growth.

Many tech companies aren't profitable, so the price-to-earnings ratio can't evaluate them. Revenue growth matters more for younger companies. If you're investing in something unproven, you want to make sure it has solid growth prospects.

For unprofitable tech companies, it's also important that the bottom line be moving from losses toward profits. As a company grows, it should become more efficient, especially when it comes to the sales and marketing spending necessary to close deals. If it's not, or if spending is growing as a percentage of revenue, that could indicate something is wrong.

Ultimately, a good tech stock is one that trades at a reasonable valuation, given its growth prospects. Accurately figuring out those growth prospects is the hard part. If you expect earnings to skyrocket in the coming years, paying a premium for the stock can make sense. But if you're wrong about those growth prospects, your investment may not work out.

Investing in an exchange-traded fund (ETF) that focuses on tech stocks is one way to avoid making mistakes. The iShares Expanded Tech Sector ETF (IGM -0.34%) is a comprehensive option at a 0.41% expense ratio.

Investing in tech stocks can be risky, but you can reduce your risk by investing only when you feel confident their growth prospects justify their valuations.
