Prediction: Nvidia stock's post-earnings-release move will largely hinge on news about the H20 chip for China and related Q3 guidance.

AI bellwether Nvidia is slated to report quarterly results after markets close on Wednesday, and traders are prepared for the stock's biggest post-earnings move in more than a year.

Wall Street expects Nvidia to report earnings per share of $1.01 on revenue of $46.13 billion. A slew of Wall Street analysts have raised their price targets on Nvidia leading into the release, but at least one of those analysts warned the quarter may not impress to the level investors have become accustomed to over the past several years.
