US Stock Market Move | NVIDIA Corporation (NVDA.US) opened higher but closed lower, falling more than 4%; a well-known investment bank says there is still considerable uncertainty surrounding management changes.

On Friday, NVIDIA Corporation (NVDA.US) opened higher in early trading but reversed gains and was last down more than 4% at $159.40. After NVIDIA Corporation announced that Jensen Huang has resigned as Chief Executive Officer and as a director, well-known Wall Street investment bank Bernstein released its latest research report saying that although NVIDIA Corporation's current stock valuation is already at a highly attractive level and the management change is not expected to have a significant impact on the company's near-term business, there is still considerable uncertainty surrounding subsequent developments and whether the new chief executive will be able to continue the operating strategy under Jensen Huang's leadership. Therefore, the bank maintained its "Market Perform" rating on NVIDIA Corporation and its $200 price target.
