As the US equity markets prepare to open, futures are showing a mixed tone. The S&P 500 (ES) is down 0.2%, the Nasdaq (NQ) is flat, and the Russell 2000 (RTY) is up 0.2%. Beneath the surface, several notable pre-market movers are catching attention due to earnings reports, guidance updates, M&A activity, and analyst actions. Here’s a closer look at the most significant movers and what’s driving them.
Parson Corp ($PSN) – Down 3%
Parsons is under pressure this morning after cutting its full-year revenue outlook. While the company hasn’t released full earnings yet, this guidance revision has weighed on investor sentiment. Revenue guidance is often seen as a forward-looking indicator of corporate health, so any downward revision tends to prompt a cautious reaction from the market. Investors are reassessing growth expectations as the company navigates a potentially more challenging environment.
Signet Jewelers ($SIG) – Up 13%
Signet delivered a strong earnings surprise, with EPS beating expectations. More importantly, the midpoint of its fiscal year 2026 guidance came in above consensus estimates. This signals management confidence in continued growth and margin stability despite macroeconomic uncertainties. The market is rewarding the company for both current execution and forward visibility, particularly in a discretionary sector like jewelry, which often reflects consumer sentiment.
Dollar General ($DG) – Up 11%
Dollar General is also seeing a surge after reporting better-than-expected EPS and revenue. The company further supported the rally with a solid outlook for same-store sales (SSS) for the fiscal year. As a discount retailer, Dollar General tends to perform well when consumers tighten their budgets, but this result suggests that management is also executing well on strategic initiatives. The upbeat forecast reassures investors that the company is positioned to capture value in a complex retail environment.
MoonLake Immunotherapeutics ($MLTX) – Up 21%
MoonLake is skyrocketing in pre-market trading following news that Merck has made a nonbinding offer to acquire the company for over $3 billion. While details are limited, the market clearly sees strategic value in the potential acquisition. The move highlights continued interest in biotech consolidation, especially among large pharmaceutical firms looking to bolster their pipelines in immunology and inflammation.
Taiwan Semiconductor Manufacturing Co. ($TSM) – Down 0.2%
TSMC shares are slightly lower after comments from the company noted that US tariffs are having some indirect effects on operations. However, the silver lining is that demand for AI chips remains robust, continuing to outstrip supply. This ongoing imbalance between AI chip supply and demand reinforces TSMC’s central role in the global tech ecosystem, although macro factors like trade policy are creating some near-term uncertainty.
Constellation Energy ($CEG) – Up 14%
CEG is surging after news that Meta Platforms will purchase nuclear-generated power from Constellation to run its data centers. This is a significant development as tech companies face growing pressure to green their operations. The move signals increasing commercial demand for carbon-free power sources and positions CEG as a key player in the energy transition narrative. The deal adds a layer of long-term revenue stability and enhances the investment case for Constellation.
Bumble Inc. ($BMBL) – Down 5.5%
Bumble is trading lower following a downgrade from JPMorgan. While the specific rationale has not been disclosed in pre-market summaries, downgrades from major analysts often trigger swift reactions, especially in volatile or sentiment-driven stocks like those in the tech and app-based service sectors. Investors may be factoring in slowing growth, competition concerns, or valuation pressures.
Pinterest ($PINS) – Up 4%
Pinterest is moving higher after receiving an upgrade from JPMorgan. This vote of confidence suggests improving fundamentals or a more attractive valuation. Pinterest has been making progress in monetization and user engagement, and this analyst move may reflect optimism around ad revenue growth or new product initiatives.
Market Outlook
The pre-market landscape reflects a mix of earnings-driven moves, strategic M&A speculation, and evolving investor preferences toward energy and tech. While the broader indexes are relatively flat, individual stock movements point to a market that is increasingly selective, with a sharp focus on forward guidance and strategic positioning.
As markets open, expect volatility to remain elevated around these names as investors digest the new information and position accordingly.
