The Cheapest Trillion-Dollar Stock: Nvidia, Microsoft, Apple, Amazon, Alphabet, or Meta?

Six U.S. companies are valued at $1 trillion or more, and they all operate in the technology sector:

1. Apple (NASDAQ:AAPL): $3.44 trillion
2. Microsoft (NASDAQ:MSFT): $3.16 trillion
3. Nvidia (NASDAQ:NVDA): $3.14 trillion
4. Alphabet (NASDAQ:GOOGL)(NASDAQ:GOOG): $2.07 trillion
5. Amazon (NASDAQ:AMZN): $1.87 trillion
6. Meta Platforms (NASDAQ:META): $1.33 trillion

All of these companies are profitable, so they can be valued with the widely used price-to-earnings (P/E) ratio. It's calculated by dividing the share price of a given company by its earnings per share. The Nasdaq-100 index trades at a P/E ratio of 30.9, which is a good reference point:

Data by YCharts.

Nvidia is the most expensive trillion-dollar stock today on a P/E basis. However, the company is growing so quickly it has a forward P/E ratio of just 33.1 based on next year's earnings forecast. In other words, its valuation is much more reasonable if investors are willing to hold it for a couple of years.

The cheapest stock of the group is Alphabet. A judge recently ruled that Google Search is a monopoly, and the U.S. Department of Justice wants to break up the company to resolve that issue. It could take years -- if it happens at all -- but combined with growing competition from artificial intelligence chatbots, which are threatening the dominance of Google Search, investors are treading cautiously with respect to Alphabet's valuation.

Finally, Amazon deserves a mention. It's on track to generate $635 billion in revenue this year, which is more than any of its peers, and it trades at the cheapest price-to-sales ratio (which divides a company's market capitalization by its revenue). Plus, its earnings are forecast to grow 63% this year and 23% in 2025, so its elevated P/E ratio might actually be justified.

In summary, a P/E ratio alone isn't always the best indicator of value. Investors could easily make the case that despite trading at triple the P/E ratio, Nvidia stock is a better buy than Alphabet because of its rapid growth (and Alphabet's regulatory headwinds).
