Nvidia is expected to report fiscal first-quarter earnings after market close on Wednesday. Analysts forecast a more than 400% rise in EPS and a 200% increase in revenues yearly. Wall Street expects strong results but signs of deceleration from the previous quarter's growth rates of more than 700% EPS and 200% revenues. Analysts note Nvidia's transition from older H100 chips to new Blackwell chips could impact results and cause short-term volatility.
