Nasdaq 100 and S&P 500 Rise Over 1% as U.S. Equity Markets Extend Gains

The assessment is based on the descriptions of several high-authority and highly relevant primary sources. The FRED data feed (Source 1) is a direct, authoritative source for the Nasdaq 100's daily percentage change. Similarly, the S&P Global 'Daily Index Dashboard' (Source 2) and the 'Performance Reports' portal (Source 3) are described as providing the exact primary data needed to verify the S&P 500's performance, and likely the Nasdaq 100's as well. These are the definitive sources for this type of information, originating from the institutions that maintain the indices.There is no conflicting evidence presented. While a secondary source from Charles Schwab (Source 5) mentions that "Stocks Rise," it lacks the specific percentage needed for confirmation. The remaining sources are largely irrelevant as they focus on individual stocks, futures, or options rather than the daily performance of the indices themselves. Given that the most appropriate and authoritative sources for verifying the claim are provided and described as containing the necessary data, the statement is very likely to be a factual report of the market's performance. The assessment is not 'confirmed true' only because the exact percentage values are not quoted in the source summaries, but the nature of the evidence strongly supports the statement's truthfulness.
