NEW YORK — Apple may have owned the headlines ahead of its biggest product launch of the year, but some of Wednesday’s most dramatic moves on Wall Street came from companies selling jewelry, pizza, software and avocados.
Before the September 9 opening bell, Signet Jewelers surged roughly 17%, Casey’s General Stores dropped more than 10%, ServiceTitan plunged more than 17%, and Mission Produce jumped about 7.5%, according to premarket trading reports. Apple, meanwhile, was only modestly lower ahead of its highly anticipated hardware event.
The moves provided a revealing snapshot of the current U.S. market: simply beating Wall Street’s headline earnings estimates is no longer necessarily enough.
Investors are increasingly looking past earnings per share and revenue toward same-store sales, forward guidance, margins, artificial intelligence monetization and signs of weakening consumers.
And companies that failed those secondary tests were punished — sometimes brutally.
Signet Jewelers: The day’s surprise winner
One of the biggest winners was Signet Jewelers, the owner of Kay Jewelers, Zales and Jared.
Signet reported fiscal second-quarter adjusted earnings of $2.19 per share, substantially ahead of the roughly $1.74 expected by analysts. Revenue was about $1.53 billion, while same-store sales increased 2.2%.
More importantly, Signet raised its full-year outlook.
The jeweler now expects fiscal 2027 adjusted earnings of $10.45 to $12.15 per share, compared with its previous forecast of $9.20 to $11.
The company also announced an expanded share-repurchase program, including a planned $125 million accelerated share repurchase.
That combination — stronger profit, improving comparable sales and a higher forecast — was exactly what investors wanted.
Signet rose around 17% before the opening bell and accelerated once regular trading began. Shares ultimately surged roughly 24%, according to Barron’s, making it one of Wednesday’s standout performers.
The contrast with Casey’s could hardly have been sharper.
Casey’s beat Wall Street — and investors sold it anyway
On paper, Casey’s General Stores appeared to deliver a strong quarter.
The convenience-store operator reported fiscal first-quarter earnings of $7.37 per share, up nearly 28% from a year earlier. Revenue jumped more than 24% to approximately $5.68 billion.
Net income rose to $273.7 million, while EBITDA increased 17.1% to $485.1 million.
Those numbers exceeded Wall Street expectations.
Yet Casey’s shares collapsed.
The problem was buried deeper in the operating numbers.
Inside same-store sales increased just 3.2%, below what some analysts had expected. Fuel gallons sold at comparable stores slipped 0.3%, while prepared-food and dispensed-beverage same-store sales rose 4.8%.
For a stock that had already been trading at a relatively rich valuation, investors apparently wanted something closer to perfection.
Casey’s fell more than 10% premarket and finished Wednesday down more than 14%, despite beating consensus estimates for both earnings and revenue.
That makes the reaction particularly noteworthy.
Wall Street was not questioning whether Casey’s was profitable. It was questioning whether the company’s underlying growth was strong enough to justify expectations already embedded in the share price.
That distinction is becoming increasingly important across the market.
ServiceTitan shows why “beat and raise” may still not be enough
Software company ServiceTitan delivered an even more dramatic example.
The company reported fiscal second-quarter revenue of $292.8 million, up 21% year over year and above Wall Street estimates of roughly $285.9 million.
Adjusted earnings were also better than expected.
Yet the stock was crushed.
ServiceTitan projected third-quarter revenue of only $285 million to $287 million, slightly below the approximately $288 million analysts had been expecting.
That apparently small difference was enough to trigger a huge selloff.
The stock fell more than 17% before the opening bell and ultimately plunged around 30% during regular trading, its worst move of the group.
The company still expects full-year revenue between $1.139 billion and $1.144 billion, and management highlighted growing adoption of its AI-oriented products.
But investors focused on the near-term slowdown.
It was another reminder that in highly valued technology stocks, the next quarter can matter more than the quarter that just ended.
Braze gets caught in Wall Street’s AI expectations
Marketing software company Braze faced similar pressure.
Braze reported adjusted earnings that topped expectations and revenue of about $227 million, representing roughly 19% growth.
Even so, investors were disappointed with certain forward-looking metrics and questioned how quickly the company could convert its artificial-intelligence initiatives into faster revenue growth.
Shares fell roughly 11% in early trading and ended the day down considerably more.
Barron’s reported that the selloff eventually approached 22%.
The reaction illustrates how aggressively Wall Street is now pricing AI expectations into software companies.
Talking about AI is no longer enough.
Investors increasingly want evidence that AI is producing measurable revenue, customer growth or higher margins.
Mission Produce jumps as avocado volumes surge
At the other end of the market, avocado distributor Mission Produce climbed about 7.5% before the bell after reporting stronger-than-expected quarterly results.
Fiscal third-quarter revenue jumped 26% to $450 million, while avocado volumes climbed 38% year over year.
The company did report a $6.5 million net loss attributable to Mission Produce, partly because of costs associated with its Calavo acquisition. Management also increased its estimate for annualized synergies from that transaction to more than $30 million.
The stock’s positive reaction showed that investors were willing to look through acquisition-related expenses when underlying operating trends appeared favorable.
Apple had the biggest headline — but not the biggest stock move
Then there was Apple.
Apple shares edged lower before the opening bell as traders waited for the company’s September product event.
The event carried unusual significance because it was the first major iPhone launch under new CEO John Ternus.
Apple later introduced the iPhone 18 Pro and Pro Max alongside its first foldable smartphone, the iPhone Duo, priced starting at $1,999.
Despite the historic product debut, investors delivered a restrained response.
Apple initially fell more than 2% during the presentation before recovering most of the decline and ending Wednesday only about 0.3% lower.
In other words, the company generating perhaps the day’s biggest technology headline produced one of the smallest stock moves among the major names being watched before the bell.
That itself says something about investor expectations.
Much of Apple’s product news had already been anticipated, leaving fewer surprises capable of dramatically changing the market’s valuation of the company.
Oil above $100 becomes the bigger threat hanging over Wall Street
Corporate earnings were not the only force moving stocks Wednesday.
Brent crude climbed back above $100 a barrel, fueled by escalating Middle East tensions and concerns about oil supplies.
Higher crude prices intensified fears that inflation could remain elevated and pushed Treasury yields higher.
Energy shares benefited, while the broader market struggled.
The S&P 500 fell roughly 0.5% to 7,636.36, the Dow Jones Industrial Average dropped about 0.8% to 52,380.66, and the Nasdaq Composite declined 0.6% to 26,253.34.
The Russell 2000 lost 1.3%.
Investors are also waiting for key U.S. inflation readings ahead of the Federal Reserve’s next policy decision, adding another layer of uncertainty to already volatile trading.
The lesson from Wednesday’s wild stock moves
The biggest takeaway may not be that Signet rose or Casey’s fell.
It is why they moved.
Casey’s beat earnings expectations and still suffered one of its sharpest declines in years because investors found weakness underneath the headline numbers.
ServiceTitan beat revenue estimates and raised parts of its annual outlook, yet its near-term forecast disappointed enough to erase roughly 30% of its market value in a single session.
Signet, meanwhile, delivered exactly what this market currently rewards: an earnings beat, improving comparable sales and a meaningful increase in guidance.
Apple unveiled an entirely new category of iPhone and barely moved.
That is the market Wall Street investors are navigating now.
Good results are not necessarily good enough.
With oil above $100, Treasury yields elevated, inflation data approaching and valuations already demanding strong execution, investors appear increasingly unwilling to overlook even small cracks in corporate forecasts.
And Wednesday’s biggest movers showed just how expensive one disappointing number can become.
