There is a wide gap between the most expensive and cheapest trillion-dollar stock, according to one widely used valuation metric.
Six U.S. companies are valued at $1 trillion or more, and they all operate in the technology sector:
- Apple (AAPL 0.70%): $3.44 trillion
- Microsoft (MSFT -0.12%): $3.16 trillion
- Nvidia (NVDA 3.48%): $3.14 trillion
- Alphabet (GOOGL 0.67%) (GOOG 0.72%): $2.07 trillion
- Amazon (AMZN 0.48%): $1.87 trillion
- Meta Platforms (META -0.16%): $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:

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).
