The provided web search results for this claim are irrelevant, discussing the letter 'S' rather than the S&P 500 index. No financial data was provided to confirm the index rose above 7,400 on a specific Monday.

The evidence provided contains general information about the S&P 500 and historical annual returns, but does not provide specific price data for March 30 or a percentage increase from that date.

The evidence provides general company information and links to Yahoo Finance, but does not contain the specific stock price movement or percentage increase (140%) for Micron Technology over the mentioned span.

One web search result ('There’s a new top target for the S&P 500...') explicitly mentions that usually when the S&P 500 was this extended, an average of 86% of components traded above their 50-DMAs. However, there is only one source providing this specific statistic.

While one source mentions the index being extended and the 86% average, it does not provide the specific figures for 'Friday' (7.7% higher and 52% of members topping the measure).

The search results for this claim are dictionary definitions of the word 'according' and do not contain any financial data or BTIG findings.

The provided evidence discusses general record highs and a rally in 2025, but does not confirm the specific historical occurrence of new highs with more new lows in December 1999.
