"Everyone's been waiting for" Nvidia's (NVDA) earnings, says Dave Mazza. He'll look for data center and revenue growth but expects a "messy quarter" when it comes to China sales and tariffs. That said, Dave sees Nvidia being "very adept" to trade restrictions and will carve out a new path for profits if needed. As long as Nvidia shows a clear, strong path for guidance, he expects the stock to rally.
