Only 25% of S&P 500 Industry Groups Above 10-Week Average

The assessment is primarily based on a highly relevant source from Mark Ungewitter, a portfolio manager and market analyst. This source states that 'one quarter' (25%) of S&P 1500 industry groups are above their 10-week moving average. This aligns perfectly with the percentage and metric in the user's statement.The minor discrepancy is the index cited (S&P 1500 vs. S&P 500). However, the S&P 1500 is a composite index that includes the S&P 500, S&P 400 (mid-cap), and S&P 600 (small-cap). Breadth metrics like this are typically highly correlated across these closely related indices. Therefore, it is highly probable that the figure for the S&P 500 is either identical or very close to 25%.The other sources are less helpful. The Charles Schwab article discusses a related but different metric (percentage of *member stocks*, not *industry groups*), offering weak circumstantial support at best. The State Street and Yahoo Finance sources lack the specific breadth data required to validate or refute the claim.In summary, with one authoritative and highly relevant source providing a data point that is almost certainly a proxy for the statement's claim, and no conflicting evidence from the other sources, the statement is assessed as 'likely_true' with high confidence.
