The S&P 500's top 10 stocks now make up 39% of the index, with Nvidia leading at 7.78%, according to GFdaily. That concentration is drawing heavy attention as readers track how much of the market's weight sits in a small group of names.

Coverage of the topic has accelerated sharply. Headlines over the last 14 days total 200. The last 7 days account for 174 of them, while the previous 7 days had 26.

The jump in headlines shows concentration is no longer a niche concern. Watch whether the top 10 share keeps climbing and whether Nvidia's 7.78% weight holds, since both shape how the index moves.
