Have you ever watched your investment account swing wildly in just a few hours because one company decided to share its future plans? That’s exactly what happened on February 13 2026, when the market reacted sharply to fresh earnings reports and forward-looking statements. Some stocks soared while others took a beating, reminding us how quickly sentiment can shift in today’s fast-paced trading environment.
It’s days like this that make investing feel both thrilling and nerve-wracking. One minute you’re celebrating unexpected upside, the next you’re wondering if that dip is a buying opportunity or a warning sign. I’ve always found these moments fascinating because they reveal so much about investor psychology and where the smart money is heading next.
Today’s Biggest Midday Stock Movers Explained
The session delivered plenty of drama, with several names posting double-digit percentage moves. Let’s break down the standouts and what drove the action. These aren’t just random fluctuations—each tells a story about expectations, execution, and future potential.
Rivian Automotive Powers Higher on Optimistic Delivery Goals
Rivian Automotive stole the show with shares jumping around 26%. The electric vehicle maker delivered better-than-expected quarterly results and followed up with guidance that got investors excited. They projected vehicle deliveries between 62,000 and 67,000 units for the year, representing a substantial increase from prior levels.
That kind of growth projection in the EV space is hard to ignore. The company also narrowed its adjusted loss compared to what analysts had feared, and revenue came in slightly above forecasts. In my experience, when an EV player shows concrete signs of scaling production without massive surprises on the cost side, the market tends to reward it handsomely—at least in the short term.
- Delivery outlook signals strong demand recovery
- Improved loss per share shows better cost control
- Revenue beat adds credibility to management targets
Of course, the EV landscape remains competitive. But Rivian’s focus on premium trucks and SUVs seems to be resonating, and this update gave bulls plenty of ammunition. Whether the momentum holds depends on execution, but for now, it’s one of the clearest winners of the day.
Moderna Delivers Upbeat Revenue Vision
Biotech giant Moderna climbed about 5% after sharing full-year revenue guidance that topped expectations. The company anticipates growth up to 10% over the previous year, comfortably beating consensus calls for a more modest increase. Their quarterly loss was also narrower than projected.
It’s refreshing to see a biotech firm move past pandemic-era peaks and chart a path forward with confidence. Pipeline progress and commercial execution appear to be paying off. Perhaps the most interesting aspect here is how the market rewarded the forward-looking optimism rather than dwelling solely on past results.
Strong guidance can sometimes outweigh current quarter numbers when investors sense long-term potential.
– Market observer insight
Moderna’s ability to narrow losses while projecting solid growth suggests operational improvements are taking hold. For anyone following the sector, this feels like a vote of confidence in their diversified approach beyond just vaccines.
Instacart Surges on Strong Transaction Value Outlook
Maplebear, the parent of grocery delivery platform Instacart, saw shares rise roughly 9%. The company issued an encouraging forecast for gross transaction value in the current quarter, coming in well above Street estimates. Adjusted EBITDA guidance also beat expectations, and the prior quarter delivered a revenue surprise.
Grocery delivery has matured quite a bit since the early pandemic rush. Instacart appears to have found a groove with consistent growth and profitability improvements. When a company repeatedly tops numbers and guides higher, it builds credibility fast. That’s what we’re seeing here.
Investors seem to like the stability in consumer spending patterns reflected in these results. It’s not flashy like some tech plays, but steady execution tends to win over time.
DraftKings Tumbles on Disappointing Revenue Forecast
On the flip side, DraftKings shares dropped about 13% despite posting better-than-expected quarterly earnings. The sports betting operator earned more per share and slightly topped revenue estimates, but the full-year revenue guidance landed far below consensus.
Markets hate negative surprises on forward guidance. When expectations are sky-high, anything short of perfection can trigger sharp selling. In this case, the gap between what analysts hoped for and what management projected was significant enough to spark a sell-off.
I’ve noticed that in growth-oriented sectors like sports betting, guidance cuts can hurt more than earnings beats help. It’s a reminder to pay close attention to what companies say about the road ahead, not just what they achieved recently.
Other Notable Movers Worth Watching
Several other names posted meaningful moves. Roku rose nearly 8% on better-than-expected forward guidance for adjusted EBITDA and revenue. The streaming platform continues to benefit from advertising recovery and user engagement trends.
Applied Materials jumped 9% after blowout quarterly results, with both earnings and revenue surpassing forecasts. Semiconductor equipment demand remains robust, and this report reinforced that narrative.
- Coinbase climbed 17% as crypto trading volumes exploded higher year-over-year
- Dexcom gained nearly 9% on solid quarterly earnings despite steady full-year guidance
- Vertex Pharmaceuticals rose 6% with a slight revenue beat in the quarter
Not everything was positive, though. Pinterest plunged 18% after mixed results and soft forward commentary. Expedia slid more than 7% despite beating expectations, as investors focused on competitive risks mentioned in the presentation. Norwegian Cruise Line dropped 5% following a CEO change.
Constellation Brands fell around 5% after announcing a leadership transition. Wendy’s shares rose 4% on better-than-expected quarterly numbers. These varied reactions highlight how context matters—beats don’t always guarantee gains if other concerns dominate the conversation.
Broader Market Context and What It Means
Days packed with earnings reactions often set the tone for the near term. When big movers emerge from different sectors, it suggests broader themes at play. Here we saw strength in EVs, biotech, delivery services, and crypto-related names, while some consumer discretionary and leisure plays lagged.
Perhaps the most interesting aspect is how forward guidance overshadowed current results for many companies. Investors appear laser-focused on what’s coming next rather than celebrating past wins. That’s typical in uncertain times, but it also creates opportunities for those willing to dig deeper.
From my perspective, the Rivian move stands out as particularly meaningful. If the company can deliver on those ambitious targets, it could shift perceptions about the entire EV adoption curve. On the other hand, sharp declines like DraftKings remind us that high expectations can lead to equally sharp corrections.
Looking ahead, earnings season continues to unfold. Each report adds another piece to the puzzle of where the economy and specific industries are headed. Staying disciplined means separating noise from signal—focusing on sustainable trends rather than knee-jerk reactions.
Whether you’re a long-term holder or active trader, days like February 13 2026 offer valuable lessons. Volatility creates chances, but only for those prepared to analyze beyond the headlines. Keep watching these names; their next updates could move markets again.
The market never stays still for long. What feels like a big move today might look minor next month. That’s the beauty—and challenge—of investing. Stay curious, stay patient, and always question the narrative.
