Direct answer
Most large US companies reported stronger profits than expected in the third quarter of 2026. According to FactSet’s earnings update on October 30, 2026, 60% of S&P 500 companies had reported results, and 82% of them beat earnings per share estimates. FactSet put blended earnings growth for the quarter at 30.2% compared with a year earlier, with revenue up 13.4%. A second tracker, Refinitiv, reported a very similar beat rate of 81.6% from 299 companies, which supports the same broad picture even though the two trackers calculate overall growth slightly differently.
What happened
The S&P 500 is an index of 500 large US listed companies, covering many industries from technology and energy to health care and banks. Each earnings season, companies report their results for the past quarter and analysts compare those results with forecasts made beforehand. FactSet’s October 30 update is a snapshot partway through the season, not the final result for all 500 companies.
The headline numbers were strong. FactSet said 82% of companies that had reported beat earnings per share estimates, above the five year average of 78% and the ten year average of 77%. Earnings per share is simply a company’s profit divided by the number of its shares, so beating the estimate means the company earned more per share than analysts expected.
The size of the average beat was smaller than usual, however. In aggregate, companies reported earnings 1.9% above estimates, well below the five year average surprise of 7.5%. In plain terms, many companies cleared the bar, but most did not clear it by a large amount.
Growth was broad, not limited to one industry. FactSet said all eleven sectors in the index reported year on year earnings growth, and seven sectors reported double digit growth, led by Energy, Information Technology, and Materials. Blended earnings growth of 30.2% combines actual results for companies that have reported with estimates for companies that have not yet reported, so the final figure will move as the rest of the season comes in. It was already higher than the 29.1% growth rate estimated at the end of September, which means results so far have come in a little better than expected overall. If 30.2% holds, it would be the third straight quarter of earnings growth above 25% and the eighth straight quarter of double digit growth.
Refinitiv’s separate tracker told a similar story on the beat rate, with 81.6% of 299 reporting companies above expectations, against a long term average of 67%, and blended revenue growth of 13.6%, close to FactSet’s 13.4%. Refinitiv put overall earnings growth at 31.6%, a little higher than FactSet’s 30.2%, because the trackers count companies and estimates in slightly different ways. The small gap is normal and does not change the main finding: profits grew fast and most companies beat forecasts.
This strong earnings picture arrived in the same week that US stocks fell sharply, as covered in the recent post on US stocks ending October with a sharp Friday sell-off, linked here: https://investclaritypath.com/us-stocks-end-october-sharp-friday-selloff/. That contrast is important. Earnings describe the quarter that just ended, while share prices also reflect what investors expect next, including worries about heavy spending on artificial intelligence and higher interest rates.

Why it matters for beginners
Earnings season is one of the clearest health checks on large companies. When profits grow across many sectors at once, it usually means demand, pricing, or cost control is holding up across the economy, not just at one famous company. That is why a scorecard for the whole index can matter more than any single company’s result.
The beat rate also teaches a useful lesson about expectations. A company can report higher profits than last year and still disappoint if analysts expected even more. Markets often react to the surprise, the gap between the result and the forecast, rather than to the profit figure alone. That helps explain why a season can look strong in the data while some share prices still fall.
The small average surprise matters too. If most beats are narrow, companies have less room for error in the next quarter. A small miss on sales, a rise in costs, or a cautious outlook can then move a share price a lot, even when the business itself is still profitable. Beginners often focus only on whether a company beat or missed, but the size of the beat and the outlook for the next quarter usually matter just as much.
Finally, blended growth is an estimate, not a final score. It mixes real reported results with forecasts for companies that have not reported yet. As the remaining 40% of the index reports, the growth rate for the quarter will be revised. Treat mid-season figures as a progress report, not as a finished result.
What to watch next
- The rest of earnings season, including Apple and Nvidia, which had not yet reported when these snapshots were published, and whether the overall growth rate stays near 30%.
- Whether the average earnings surprise stays near 1.9% or widens, since a narrow surprise leaves less cushion for the next quarter.
- Company outlooks for the fourth quarter, especially on spending, margins, and demand, rather than only the third quarter profit figure.
- Whether broad growth holds outside Energy and Technology, or whether it narrows to a few sectors as more companies report.
- The next FactSet and Refinitiv updates, and whether their growth estimates move closer together or further apart as the season completes.
FAQ
What is the S&P 500?
The S&P 500 is an index of 500 large companies listed on US stock exchanges. It covers many industries and is often used as a rough measure of how large US companies are doing as a group. An index itself is not a company, and its level moves with the combined value of its member companies.
What does it mean to beat earnings estimates?
Analysts forecast a company’s earnings per share before results are published. If the reported figure is higher than the forecast, the company beat estimates. If it is lower, it missed. The beat rate is the share of reporting companies that beat, so 82% means about four in five reporting companies came in above forecasts.
What is blended earnings growth?
Blended growth combines actual reported earnings for companies that have already published results with estimated earnings for companies that have not yet reported. It gives a current best estimate for the whole index for the quarter, but it will change as more real results replace estimates.
Why do FactSet and Refinitiv report slightly different growth rates?
Different data providers use different company counts, estimate dates, and calculation methods, so their blended growth figures can differ by a percentage point or two. When both trackers agree on the direction and on a similar beat rate, as they do here, the broad story is more reliable than any single decimal point.
Why did stocks fall if earnings were so strong?
Earnings look backward at the quarter just ended, while share prices look forward. Investors were also weighing heavy spending on artificial intelligence, higher interest rates, and what companies said about the next quarter. Strong past profits do not guarantee that investors will expect equally strong profits ahead, and that forward view can move prices on the day.
Does strong earnings growth mean I should invest?
No. This post explains what the data showed, not what any individual should do. Earnings growth is only one piece of information, and it sits alongside valuations, interest rates, personal goals, and risk tolerance. Past profits also do not guarantee future profits.
