Index concentration is a portfolio decision you did not make
The index traded at 764.38, -0.32% today. Buying the market used to mean diversification. It is worth checking whether it still does.

The index traded at 764.38, -0.32% today. Buying the market used to mean diversification. It is worth checking whether it still does.
It traded at 279.98, -0.14% today. The gap between large and small is a balance sheet story before it is a growth story.
It traded at 745.04, +0.32% on the session. Large options prints get reported as conviction. Most of them are somebody hedging.
The equal-weight S&P sat at 219.02, +0.10% on the day. Cap weight tells you what a handful of names did. This tells you what the market did.
After a stretch where a few names carried the index, more members are participating again. That is what long advances are built on.
When index puts are cheap relative to calls, nobody is worried. That is a warning sign, and warning signs can stay lit for a long time.
The VIX curve usually slopes upward: calm now, more uncertainty later. When it flattens, near-term worry has caught up with the long-run kind.
When dealers hold options that make them buy dips and sell rallies, their hedging calms the index. That calm tends to favour a slow grind higher.
The two conditions I track for small caps, and how rarely they line up.
Small caps can rally hard when the most indebted and most shorted names lead. That is a different animal from a rally built on improving earnings.
When leadership rotates from one group of large names to another, the index can look shaky without anyone selling the market.
An index can keep rising while fewer and fewer of its members do the work. That narrowing usually ends the advance before the headline level shows any strain.
