SHORT AND SWEET
Nvidia, at more than US$4 trillion in market capitalisation, is the largest stock to ever exist. The company’s quarterly earnings announcements have become Super Bowl-like events.
In its August 2025 release, Nvidia reported past 12-month earnings that were over 60% higher than this time last year, compared to an approximately 14% rise for combined S&P 500 earnings over the same period. Despite this, the stock fell slightly the next day.
Nvidia’s earnings were immense, but the price tag for those earnings is steep. As of 31 August 2025, Nvidia’s market cap made it nearly 8% of the S&P 500 Index. Its last 12 months of earnings were US$87 billion, or around 4% of the approximately US$2 trillion in total S&P 500 Index earnings. For investors seeking higher returns, the company’s size and high valuation relative to peers suggest that markets continue to price in high future cash flows, lower expected returns, or a combination of both. As a result, even when Nvidia announces eye-wateringly high earnings, its price may still drop.
Stock prices are an investor’s most valuable source of information and contain the market’s aggregated outlook for a stock’s future. Investors who own the broad market will get a slice of Nvidia, including a claim on Nvidia’s future earnings.
