Indexes Fri 2026-03-20: Unchanged SOX (4Strong); Weakened/-1 SP500 (6Weak), NDX (6Weak), MAG7 (7Weaker)

This post shows strengthening/weakening detail for this week for the S&P 500, Nasdaq 100, the Philadelphia Semiconductor Index (SOX), and the so-called Magnificent 7 stocks (MAG7).

Comment: for the MAG7 which now has weakened to a 7Weaker rating, the "strongest" stocks are only at 5Average (GOOG, AAPL) while the three weakest stocks AMZN, META, and MSFT are 9Weakest. This marks the fourth time in the past seven weeks that the MAG7 has weakened rating, from its recent high of 3Stronger eight weeks ago. The relevance of this rating system is that one can easily see there are still two more ratings for it to potentially fall, to 9 Weakest, IF it does keep falling. In other words, this system is good for discerning if and when a given vehicle is at an extreme. When it is, that conveys the potential groundwork for mean reversion.
