Week in review, October 26 to 30: strong results, falling shares

The indexes slipped while most stocks rose. In the busiest week of results season so far, raised guidance went with rising shares, and some of the fastest growers fell hardest.

The headline indexes slipped this week. Most stocks did not. And in the busiest week of the results season so far, some of the companies with the best numbers had the worst weeks.

The week in numbers

From the close on Friday, October 23 to the close on Friday, October 30:

S&P 500 fund (SPY): down 0.6%
Nasdaq 100 fund (QQQ): down 2.0%
Dow: down a little under 1%
Russell 2000 fund (IWM): up 1.3%

Underneath, 322 of the 500 companies in the S&P 500 rose, and ten of the eleven sector funds went up, led by healthcare at 3.1%. The two that fell were communication services, down 5.3%, and technology, down 2.0%. That is where the largest companies sit: Alphabet fell 12.6% over the week and Meta 4.3%, after the results we looked at in The $200 billion quarter and Alphabet's worst day in twenty years. When the biggest names fall, the indexes they dominate fall with them, even while most of the market rises.

The indexes fell while ten of eleven sector funds rose in the week to October 30, 2026; communication services and technology were the two that fell

The busiest week of results season so far

322 companies on the Tickr Lab screener published quarterly results this week, more than double the 147 of the week before. 203 of them rose, and the median one gained 2.2%. Everything else on the screener had a median gain of 1.1%.

What the companies said about the months ahead lined up with the shares more than anything else in the releases:

The 121 that raised their guidance had a median gain of 3.6%, and 73% of them rose.
The 18 that lowered it had a median fall of 1.3%. Only 7 of the 18 rose.
The 24 that reaffirmed it gained a median 0.7%, and the 132 whose release did not state a change gained 2.3%.

Fast growth on its own was a weaker guide. The 65 companies whose revenue grew 20% or more had a median gain of 4.8%, but 22 of them fell. Across every company that reported, revenue growth and the week's share price move barely lined up at all: a correlation of 0.05, where 1 would be a perfect match and 0 none.

Median weekly share price change for the 322 companies that reported, by guidance: raised +3.6%, reaffirmed +0.7%, no change stated +2.3%, lowered −1.3%

Strong results, falling shares

The week's hardest falls came from companies whose releases read well:

ServiceNow fell 34%. Revenue grew 21% to $4.11 billion and it raised its full-year subscription revenue and free cash flow margin outlook. Its net income was $277 million, down from $502 million a year earlier.
Reddit fell 36%, the largest fall among companies in the S&P 500 or Nasdaq 100 worth over $1 billion. Revenue grew 53% to $895 million and net income rose to $283 million from $163 million. It forecast fourth-quarter revenue of $1.00 to $1.03 billion.
Fortinet fell 24%. Revenue grew 20% to $2.08 billion and it raised its 2026 revenue guidance to 20% growth.
Intel fell 24%. Revenue grew 21% to $16.5 billion. It forecast fourth-quarter revenue of $15.0 to $16.0 billion, below the quarter it had just reported.
Twilio fell 22%. Revenue grew 20% to $1.56 billion and it raised its full-year outlook. Its fourth-quarter range implies growth of 17% to 17.5%, or 11% to 12% organically.

A release does not say why a share price moved, and neither do we. What these five show is that this week, growth of 20% or more and a raised outlook were not enough to hold a share price up.

Strong results, opposite moves: ServiceNow, Fortinet, Twilio, Reddit and Intel fell between 22% and 36% on revenue growth of 20% or more; Vertiv, Carvana, Gen Digital and Huntington Ingalls rose 16% to 20%

And the ones that rose

Vertiv rose 20%. Net sales grew 61% to $4.31 billion and it raised its full-year guidance across every key measure. Vertiv makes the power and cooling equipment that data centres run on, which puts it on the receiving end of the $202 billion the four largest cloud companies spent on capital projects last quarter.
Carvana rose 18%. Revenue grew 42% to $8.04 billion, on 39% more cars sold to retail buyers.
Gen Digital rose 17% after raising its full-year guidance again.
Huntington Ingalls, the shipbuilder, rose 16% after raising its shipbuilding revenue guidance.
Pentair rose 20%, the most of any company in either index worth over $1 billion, on sales that fell 4%. The reaction to a release is not only about its headline numbers.

Next week

421 companies on the screener have announced results dates between November 2 and 6. Among the largest: Apple and Palantir on Monday, AMD, Amgen, Shopify and Arista Networks on Tuesday, Arm, McDonald's, Qualcomm and Uber on Wednesday, and Berkshire Hathaway on Friday.

What this is, and what it is not

This is a record of one week: what companies reported and how their shares moved. It is not a forecast, and it is not a view on whether any of these shares is worth owning. A week is a short time, and a share price that falls after good results can go anywhere from there.

Weekly moves are daily closing prices from October 23 to October 30, 2026. Revenue, guidance and earnings are as each company's results release stated them, read by Tickr Lab. Index figures are the SPY, QQQ, DIA and IWM funds; sector figures are the Select Sector SPDR funds. Counts of companies are those on the Tickr Lab screener.
