NVDA's Role in S&P 500 Performance Moving Forward

Following yesterday's significant move in $NVDA, I'm curious about the community's perspective on its continued outsized influence on the $SPX. While its weight in the index is substantial, the question isn't just about market cap, but about the concentration of forward earnings growth expectations tied to a single component, specifically within the AI narrative.

Are we looking at a scenario where NVDA's performance essentially dictates a significant portion of the S&P 500's trajectory for the rest of H2, or is there an expectation for broader market participation to dilute this effect? Specifically, how do you see this playing out against potential shifts in interest rate expectations or broader economic data? The argument could be made that strong NVDA performance masks underlying weakness in other sectors, creating a fragile rally.
