Picture this: the regular trading session ends, the market lights dim, and suddenly your watchlist lights up like a Christmas tree. Double-digit percentage swings in minutes. That’s the thrill—and sometimes the terror—of after-hours trading. Yesterday evening delivered exactly that kind of drama, with several high-profile companies dropping their quarterly results and forward guidance, sending shares flying in opposite directions. Whether you’re a day trader glued to the screen or a long-term investor checking emails the next morning, these moves can reshape your thinking about entire sectors.
I’ve always found after-hours action particularly telling because it strips away some of the noise of regular trading. It’s often the first unfiltered reaction from big institutions and algorithms digesting the numbers. And last night? There were clear winners, painful losers, and a few that left everyone scratching their heads. Let’s dive in and unpack what really happened, why it matters, and what savvy investors might consider doing next.
Last Night’s Standouts: The Biggest After-Hours Swings
The evening belonged to a mix of tech, electric vehicles, travel, and leisure names. Some companies crushed expectations and offered promising outlooks, while others stumbled on guidance despite decent results. Here’s a closer look at the ones that moved the needle most dramatically.
Rivian Automotive: Electric Dreams Get a Boost
Rivian shares exploded higher by around 14% in extended trading, and honestly, it’s not hard to see why. The electric truck maker delivered better-than-expected numbers for the fourth quarter and, more importantly, provided a 2026 delivery forecast that got investors excited. They’re targeting between 62,000 and 67,000 vehicles this year—a solid jump from last year’s levels, potentially up 47% to 59%.
What makes this guidance feel meaningful is the upcoming launch of their more affordable R2 model. Priced to compete directly in the mass market, it’s expected to drive the bulk of volume growth. In my view, if Rivian can execute on production ramps without major hiccups, this could mark the beginning of a real turnaround story for the company. Of course, the path is never smooth in the EV space—supply chain issues, competition, and consumer demand shifts remain real risks. Still, this felt like a moment where the market rewarded optimism backed by concrete plans.
- Adjusted Q4 loss narrower than Wall Street anticipated
- Revenue slightly above expectations
- Focus shifting toward higher-volume, lower-price-point vehicles
- Potential for significant growth if R2 launch succeeds
Is this sustainable momentum or just another short-lived pop? Only time will tell, but for EV believers, it’s a welcome sign that at least one pure-play might be finding its footing.
Applied Materials: Semiconductor Strength Shines Through
Applied Materials, a key player in chip-making equipment, saw its stock leap roughly 11% after hours. The numbers were impressive: adjusted earnings beat estimates, revenue topped forecasts, and the overall performance underscored continued demand in the semiconductor space, particularly driven by AI-related investments.
I’ve watched this sector closely over the years, and it’s clear that whenever leading-edge tech like high-bandwidth memory or advanced packaging picks up steam, companies like Applied Materials tend to benefit disproportionately. Their results suggest that despite any macro uncertainty, the build-out of AI infrastructure remains a powerful tailwind. The guidance for the next quarter also looked healthy, reinforcing the idea that this isn’t just a one-quarter wonder.
When chipmakers keep spending on next-gen tools, equipment suppliers often see the upside first.

For investors interested in the broader tech ecosystem, this move highlights why diversified exposure to semiconductors can be rewarding, even when end-demand fluctuates.
Airbnb: Steady Growth Despite Mixed Results
Airbnb’s shares climbed modestly in after-hours trading, roughly 2%, after the company released fourth-quarter numbers and offered upbeat full-year guidance. While earnings per share came in below expectations, revenue performed well, and the company projected at least low double-digit growth for the full year—better than many analysts had modeled.
Travel remains a resilient category in my opinion, especially as people prioritize experiences over goods. Airbnb’s ability to maintain pricing power and expand internationally continues to impress. The slight miss on EPS wasn’t enough to derail enthusiasm when the forward view looked constructive. Perhaps the most interesting aspect here is how the platform has evolved beyond simple vacation rentals into a broader travel ecosystem.
- Focus on core lodging remains strong
- Enterprise and group travel initiatives gaining traction
- Guidance suggests confidence in sustained demand
- Macro risks like economic slowdown could still impact discretionary spending
If you’re holding travel-related names, this report probably felt reassuring rather than exhilarating.
Pinterest: Guidance Disappoints, Shares Tumble
On the flip side, Pinterest took a painful 14% hit in extended trading. The fourth-quarter results were close to expectations—slightly light on revenue, earnings a touch below—but the real damage came from conservative first-quarter sales guidance that fell short of consensus.
Social media continues to be a tough space, with advertising budgets shifting rapidly. Pinterest has unique strengths in inspiration-driven discovery, but monetization challenges persist. It’s always disappointing to see a company punished more for what it expects than what it achieved, but that’s Wall Street for you. Long-term believers might view this as a buying opportunity if they trust the platform’s user engagement trends.
Still, the sharp reaction reminds us how sensitive growth stocks can be to any hint of deceleration. Ouch.
DraftKings: Revenue Outlook Misses, Stock Falls Sharply
DraftKings shares dropped about 15% after the sports betting operator provided 2026 revenue guidance well below Street estimates, despite beating fourth-quarter expectations on both top and bottom lines. The market clearly focused on the year-ahead view rather than the recent performance.
The sports betting industry is still maturing, with regulatory changes, competition, and user acquisition costs all playing major roles. While DraftKings continues to gain market share, the lower forecast suggests a more cautious outlook on growth rates. For investors, this is a classic case of “good news today, bad news tomorrow.” Whether this creates a value entry point or signals deeper challenges remains an open question.
| Company | After-Hours Move | Key Driver |
| Rivian | +14% | Strong 2026 delivery guidance |
| Applied Materials | +11% | Earnings & revenue beat |
| Airbnb | +2% | Upbeat full-year outlook |
| -14% | Weak Q1 guidance | |
| DraftKings | -15% | Disappointing 2026 revenue view |
This quick snapshot shows just how divergent the reactions were. Guidance clearly carried more weight than past performance in several cases.
Other Notable Movers Worth Watching
Beyond the headliners, several other names posted meaningful moves. Arista Networks jumped 18% after strong revenue guidance and an earnings beat, reinforcing the networking and AI infrastructure theme. Dutch Bros surprised to the upside with solid earnings and revenue, climbing 11%. Instacart also gained nearly 15% on a strong quarter and positive forward commentary.
On the downside, Bio-Rad Laboratories fell over 12% after missing earnings expectations and offering soft full-year growth guidance. Toast dropped more than 7% despite a slight revenue beat, as EBITDA outlook came in line rather than ahead. JFrog slipped 8% on guidance that, while solid, didn’t excite the Street.
These secondary moves highlight how interconnected sectors are right now. A semiconductor strength story lifts related plays, while cautious consumer spending outlooks can pressure discretionary names.
Broader Takeaways for Investors
So what can we learn from this batch of reports? First, the market remains laser-focused on forward guidance. Beating estimates is nice, but if the outlook disappoints, shares can still get crushed. Second, AI and related infrastructure spending continues to power certain parts of tech, while consumer-facing and growth-sensitive areas face more scrutiny.
In my experience, periods like this—when reactions are sharp and sentiment shifts quickly—often create opportunities for those willing to dig deeper. Ask yourself: Is the sell-off overdone? Does the positive move reflect genuine improvement or just relief? Patience and homework tend to pay off more than knee-jerk reactions.
Also worth noting: earnings season always brings volatility, but the dispersion in reactions this time around felt particularly wide. That usually means winners and losers are being sorted more aggressively. Staying diversified and keeping an eye on fundamentals rather than headlines remains the safest approach.
Markets don’t always make sense in the short term, but they tend to get it right over time.
Whether you’re trading the swings or investing for the long haul, last night’s action offered plenty to think about. Keep watching these names—they could set the tone for their respective sectors in the weeks ahead. And as always, do your own research before making any moves.
