Three NASDAQ names are rocketing higher on Thursday, May 7, in moves that stand out even in a strong tape. Himax Technologies (NASDAQ:HIMX) stock is up 45% intraday to $17.88, Fluence Energy (NASDAQ:FLNC) stock is up 33% to around $18, and Datadog (NASDAQ:DDOG | DDOG Price Prediction) stock is up roughly 30% to $186.50.
That’s three different industries (semiconductors, energy storage, and cloud software) all delivering the kind of single-session rallies investors usually see one at a time. The macro backdrop is constructive: the S&P 500 ETF SPY has climbed 11% over the past month, and the VIX sits at 17.39, comfortably inside of its normal range.

Yet, macro tailwinds alone don’t produce 30%-plus prints in multiple large, liquid names. Each of these stocks has its own catalyst, and all three landed on the same morning.
Himax Earnings Beat Sparks Parabolic Move
Himax Technologies posted its Q1 2026 results before the bell, with revenue of $199.01 million topping the $195.01 million consensus and EPS of $0.046 against a $0.03 estimate. Gross margin landed at 30%, at the high end of company guidance.
Inside the quarter, large display driver ICs at Himax jumped 12% sequentially to $24.2 million on high-end TV restocking, and operating margin expanded to 5% from 3% a quarter earlier. The board also declared an annual dividend of $0.252 per ADS.
The bigger driver is forward guidance. Himax sees Q2 revenue rising 10% to 13% sequentially with gross margin near 32%, and CEO Jordan Wu pointed to automotive mass-production ramps in the second half plus traction in smart glasses, ultralow power AI and co-packaged optics (CPO).
The risk is that Himax remains a small cap with cyclical end markets, and revenue was still down 8% year over year. A 45% one-day print can produce sharp follow-through volatility in either direction.
Fluence Energy Rebounds on Record Backlog
Fluence Energy reported after Wednesday’s close. Q2 FY26 revenue of $464.89 million missed the $622.31 million consensus, but EPS of -$0.16 beat the -$0.18 estimate, and management reaffirmed FY26 revenue guidance of $3.2 billion to $3.6 billion.
The bullish read on Fluence is the order book. Year-to-date order intake doubled to roughly $2 billion, backlog reached a record $5.6 billion, and the company signed master supply agreements with two hyperscalers, with a first order expected in Q3 FY26. Adjusted EBITDA also improved to -$9.44 million from -$30.41 million a year earlier.
Today’s rally still leaves Fluence Energy stock down 11% year to date. The recovery narrative depends on hyperscaler-driven demand showing up in shipped revenue, and the headline top-line miss is a reminder that quarterly execution remains lumpy.
Datadog Raises FY26 Guidance
Datadog delivered Q1 2026 revenue of $1.01 billion, up 32% year over year, with non-GAAP EPS of $0.60 against a $0.51 consensus. It marks the company’s fourth consecutive quarterly beat.
The catalyst is the raised outlook. Datadog now expects FY26 revenue of $4.3 billion to $4.34 billion and non-GAAP EPS of $2.36 to $2.44, with $100K-plus annual recurring revenue (ARR) customer count up 21% to roughly 4,550. CEO Olivier Pomel stated the company is “helping customers of all sizes and industries deploy modern, cloud-based, AI-enabled solutions.”
Datadog also pushed MCP Server, Bits AI Security Analyst, and GPU Monitoring to general availability during the quarter. Free cash flow reached $289 million, and GAAP operating income swung to a $7.33 million profit from a year-earlier loss.
The pushback for Datadog is valuation. The stock trades at a premium cloud-software multiple, and a 30% gap up compresses forward returns while amplifying any future earnings disappointment.
What to Watch
The shared thread is AI demand. Himax is leaning into co-packaged optics and smart glasses, Fluence is selling utility-scale storage into hyperscaler power footprints, and Datadog is monetizing AI workload observability through GPU monitoring and Bits AI. Three different sectors, one underlying buyer.
Single-day moves of this size tend to be followed by elevated volatility as fast money rotates and longer-term holders reset positions. Watch for whether the HIMX, FLNC, and DDOG rallies hold into the close, whether sell-side analysts raise targets within 24 hours, and whether peer names in display drivers, energy storage, and observability software trade in sympathy.
For prudent investors eyeing HIMX, FLNC, or DDOG stock, the key question is durability. The earnings reports and guidance raises are real, but chasing 30%-plus daily prints rarely rewards entry timing, and position sizing matters more than ever after a move like this. The next directional cue arrives with analyst notes overnight and the first full trading session after digestion on Friday.
