A wave of investor enthusiasm propelled ten companies to remarkable weekly gains, with some stocks witnessing increases of over 100 percent. This surge, driven by a combination of corporate developments, robust earnings reports, and positive growth outlooks, created significant wealth for investors in just one week. The stocks highlighted here all boast market capitalizations exceeding $2 billion and trading volumes above 5 million shares, with performance measured between November 7 and 14, 2025.
Top Performers of the Week
Among the standout companies, Cogent Biosciences, Inc. (NASDAQ:COGT) led the pack, soaring by an impressive 126.3 percent. The surge followed promising results from a clinical trial for its drug candidate targeting Gastrointestinal Stromal Tumors (GIST). These results indicated that patients using the drug combination experienced significantly prolonged periods without disease progression. CEO Andrew Robbins expressed optimism, stating, “With these incredible results, including a greater than seven-month improvement on median progression-free survival, the bezuclastinib combination is poised to become the new standard of care for treatment of second-line GIST patients.”
Following close behind, Cidara Therapeutics Inc. (NASDAQ:CDTX) saw its stock price more than double, increasing by 105.41 percent. The surge was fueled by news of a $9.2 billion acquisition agreement with Merck & Co., under which Merck plans to purchase shares at $221.50 each. This acquisition is expected to close in early 2026, following Cidara’s recent achievements, including a fast track designation from the FDA for its influenza preventative drug candidate.
Another notable performer, Scholar Rock Holding Corp. (NASDAQ:SRRK), witnessed a 29.2 percent boost following positive developments in its drug application for spinal muscular atrophy. After discussions with the FDA and a manufacturing contractor, the company plans to resubmit its application, aiming for a launch in 2026.
Other strong performers included Avadel Pharmaceuticals plc (NASDAQ:AVDL), which rose by 26.06 percent due to renewed acquisition interest from H Lundbeck A/S, and Baytex Energy Corp. (NYSE:BTE), which increased by 25.4 percent following its decision to exit the U.S. market, selling its Eagle Ford assets for $2.305 billion. This strategic move is expected to enhance its financial position and shareholder returns.

The list of top gainers also features Opendoor Technologies Inc. (NASDAQ:OPEN), which climbed by 23.78 percent, driven primarily by insider buying ahead of a dividend distribution. Meanwhile, Ondas Holdings Inc. (NASDAQ:ONDS) surged by 23.58 percent, riding high on an upgraded rating from investment firm Oppenheimer, which raised its target price significantly.
