NVIDIA (NVDA) remains a perennial favorite among active traders, appearing consistently on most-active lists with prices hovering around $212. The AI chipmaker’s dominance in graphics processing units for data centers keeps it front and center. Even modest daily gains coincide with massive volume—often exceeding 130 million shares—driven by ongoing hyperscaler spending and new product announcements. NVIDIA’s ecosystem, including software platforms like CUDA, cements its role as the backbone of generative AI development. finance.yahoo.com
