Why a Stock Can Beat Earnings and Still Fall

If you are new to markets, earnings season can feel confusing. A company "beats" and the stock tanks. Another "misses" and the stock rips higher. I'm a trader, and this tripped me up early on too. Let's break it down with real examples from Oct 28 and 29, 2026.

What "beat" and "miss" actually mean

Before a company reports, analysts publish estimates for earnings per share (EPS). The average is called the consensus. If actual EPS comes in above consensus, that's a beat. Below is a miss.

That is it. A beat only tells you how one number compared with one forecast. It tells you nothing about what comes next.

Example 1: F5 beat and fell 20.43%

On Oct 28, F5 reported Q4 revenue up 13% to $917 million, and adjusted EPS of $4.42 beat estimates. The stock still fell 20.43% to $365.53.

Why? F5 forecast fiscal 2027 revenue growth of 8% to 9%, down from 11% this year, along with lower margins. (SEC filing)

Lesson: the stock price is mostly about the future. Slower expected growth can outweigh a good quarter.

Example 2: SK hynix missed and rose 13.30%

Also on Oct 28, SK hynix missed per Nasdaq.com, with EPS of $3.84 vs. $5.96 consensus. The stock rose 13.30%.

On the same day, it announced a 20 trillion won treasury-share purchase and a 20,000 won per share quarterly dividend, including a special dividend. (SEC filing) One more wrinkle: the filing has no U.S. dollar EPS, so the Nasdaq figure can't be matched to it.

Lesson: a "miss" headline can hide other news, like money being returned to shareholders. Also, the miss itself may be based on a number that is hard to compare.

Example 3: Guidance moves stocks both ways

Guidance is what a company says it expects in future periods. Look at how it played out:

• Flex rose 11.61% on Oct 28 after raising its fiscal 2027 net sales outlook to $34.9 billion to $35.9 billion, up from $33.7 billion to $35.2 billion. (SEC)

• Norwegian Cruise Line rose 13.45% on Oct 29 after it "Raised full year 2026 guidance." (SEC)

• Fortinet fell 20.09% on Oct 29. Revenue rose 20% to $2.08 billion, but Reuters said it "lowered its service revenue forecast for the year." (Reuters via StreetInsider)

Raise guidance, and the stock often rewards you. Cut it, even a little, and the stock can get punished.

Example 4: Mixed news, one winner

ServiceNow fell 26.95% on Oct 29. Reuters reported that "a third-quarter profit miss overshadowed a raise to its full-year subscription revenue and cash flow margin outlook." (SEC filing)

Lesson: when a report has good and bad parts, traders decide which part matters most. You can't always predict which one wins.

GAAP vs. non-GAAP: why EPS numbers don't match

You'll often see two EPS numbers. GAAP follows standard accounting rules. Non-GAAP (also called "adjusted") removes items the company considers one-time or unusual. Examples from these two days:

• Microsoft: GAAP diluted EPS $4.92, non-GAAP $4.89. (SEC)

• Eli Lilly: EPS $7.22 reported, $7.48 non-GAAP. (SEC)

• Linde: EPS $3.66 GAAP, $4.59 adjusted. (SEC)

Data sites don't always agree, either. Intel's release shows GAAP EPS of $0.60 and non-GAAP EPS of $0.52, which doesn't match Nasdaq.com's $0.41. (SEC) And Shell's $3.86 on Nasdaq.com is per ADS, which equals 2 shares, so it lines up with $1.93 per share. (SEC)

Lesson: when two numbers disagree, go to the company's own release. That's what my team does.

A simple checklist for earnings day

1. Check EPS and revenue vs. expectations, but don't stop there.

2. Read the guidance. Is the future outlook raised, held or cut?

3. Note whether EPS is GAAP or adjusted.

4. Look for other news in the release, like buybacks, dividends or deals.

5. Read the company's own filing before trusting a headline.
