Hi Bobby — thanks for the feedback, and great question.
The best-case scenario is when most sectors are moving higher in unison. That doesn’t happen often, but it did occur during the most consistent phase of this rally from the spring through September.
When sectors begin to diverge, what we want to see is rotation into previously underperforming areas, particularly while the largest sector—Technology—underperforms but does not break down. That’s largely what we’ve seen over the past few weeks, and it has given the index room to digest gains while holding near prior highs and now pushing to new all-time highs.
The more challenging scenario would be one where the majority of non-Tech sectors continue to advance, but Technology not only stalls—it reverses lower. Given its sheer weight, it’s very difficult for the broader market to sustain upside momentum for more than a short period if the largest names are trending lower.
At that point, it becomes a numbers game. Sustained weakness in Technology would likely create a domino effect, eventually pressuring other sectors as capital is forced to move—whether from individual investors, institutions, or systematic and algorithmic strategies.
That’s why continued monitoring some of the recent tech laggards like Amazon, Microsoft, and Meta—remains critical.
Hi frank Devil advocate here. Are we sure that we can rely on this breadth indicator in such a concentrated market. Can the 490 tail wag the 10 dog. ?
Concentration: The top 10 stocks now represent nearly 42% of the entire S&P 500’s market value, up from roughly 37% a year ago.

Thank you Neural. Very well said.
