The S&P 500 reached a new milestone, hitting a record high despite the looming concerns over a two-tier bond market. Falling rates have brought relief to investors, but caution is advised as the market still faces challenges.

Investors are climbing a wall of worry with the S&P 500's rise, but one company, Nvidia, is now posing a real concern. The technology giant's stock performance is raising eyebrows, adding to the uncertainty in the market.

Market strategists emphasize the importance of the S&P 500 staying above 6,400 for the rally to continue. The August jobs report rattled the market, underscoring the need for stability.

As the S&P 500 continues its upward trend, investors are advised to stay vigilant and keep an eye on emerging trends, such as the two-tier bond market and the performance of individual companies like Nvidia. Despite the challenges, the market remains resilient, with opportunities for growth and success for investors who remain informed and adaptable.
