Last week delivered a nice reminder that when earnings meet expectations and analysts start raising their price targets, good things happen to stock prices. Between December 1 and December 5, a handful of large-cap names posted some eye-popping gains, with technology sectors leading the charge once again.
The common thread? Strong quarterly results, optimistic forward guidance, and a wave of analyst upgrades that suggested Wall Street is feeling pretty good about semiconductors, artificial intelligence infrastructure, and cloud computing right now. So let's run through the ten biggest winners from last week and see what sparked their rallies.
Space Gets First Place
AST SpaceMobile, Inc. (ASTS) took the top spot with a 31.53% surge as excitement built around the upcoming deployment of the largest commercial communications array ever sent into low earth orbit. When you're preparing to launch something that big and groundbreaking, investors tend to notice.
Cloud and Database Darlings
Rubrik, Inc. (RBRK) wasn't far behind, jumping 24.45% after delivering strong quarterly results and issuing guidance that had analysts scrambling to raise their price forecasts. The data security and management company clearly gave the Street plenty of reasons to feel optimistic about its trajectory.
MongoDB, Inc. (MDB) posted a 23.24% gain after reporting better-than-expected earnings and revenue figures. The database platform company saw multiple analysts bump up their price targets following the print, suggesting confidence in MongoDB's growth story remains intact.
Chips Making a Comeback
Microchip Technology Incorporated (MCHP) rallied 22.83% after delivering solid results and guidance that pointed to improving demand trends in the semiconductor space. Like the others, Microchip benefited from a flurry of analyst upgrades as the Street digested the improving outlook.
Amkor Technology, Inc. (AMKR) jumped 18.8% as chip and packaging stocks rebounded alongside a broader recovery in tech shares following some recent volatility. Sometimes the tide just lifts all boats, and this was one of those weeks for semiconductor names.
NXP Semiconductors N.V. (NXPI) gained 16.9% as the semiconductor rally picked up steam, driven by improving sentiment around AI applications and automotive chip demand. The broader tech rebound helped carry semiconductor stocks higher across the board.
The Retail Outlier
Dollar General Corporation (DG) was the lone non-tech name in the top ten, surging 20.9% after the discount retailer reported strong quarterly earnings and raised its full-year outlook. Multiple analysts responded by lifting their price targets, a vote of confidence in Dollar General's ability to navigate a challenging retail environment.
AI Infrastructure Gets Its Moment
CoreWeave, Inc. (CRWV) climbed 20.76% as bullish momentum around AI and GPU demand continued to support infrastructure plays. Several firms initiated coverage on the stock with price forecasts clustering in the $100 to $110 range, signaling substantial upside potential from current levels.
Samsara Inc. (IOT) rose 18.91% after posting robust results and highlighting strong demand for its connected operations cloud platform. The Internet of Things play attracted multiple analyst upgrades as the company demonstrated its ability to capitalize on digital transformation trends.
Space Race Continues

The pattern here is pretty clear. When companies deliver on earnings, provide upbeat guidance, and give analysts reasons to raise their forecasts, the market rewards them. Last week was particularly kind to technology-focused businesses riding waves of optimism in AI, semiconductors, and cloud infrastructure. Whether you owned any of these names or not, it was a good week to be exposed to tech.
