A significant 5-10% move in NVDA (up or down) after its earnings report is predicted to cause the NASDAQ and S&P 500 indices to move positively or negatively in tandem.
"If Nvidia skyrockets tomorrow five or 10%, you will see the NASDAQ and the S&P 500 will all be green. Meaning that a lot of your tech companies that are invested or any company that's part of the NASDAQ or S&P 500 will also most likely see a positive push. But if Nvidia comes in lower than what is expected, Nvidia can drop. If it drops five or 10%, it will drag down the NASDAQ and the S&P 500."
