The Dow Jones dropped 400 points Friday on a strong December jobs report. Nvidia dived on new AI chip limits. The current top five companies in the S 500 account for a greater chunk of the index than at any time over the last 60 years.

The jobs report and Nvidia chipmaker Taiwan Semiconductor loom after markets were shut Thursday for Carter's funeral. New AI chip curbs could hit NVDA.

The nearest support level for SP500 is located in the 5910 – 5920 range. In case SP500 declines below the 5910 level, it will move towards the next support at 5830 – 5840. RSI is in the moderate territory, and there is enough room to gain momentum in case the right catalysts emerge.
