S&P 500 Breadth Hits 4-Year High: The Rally Finally Has Legs
For the first time in four years, the average stock in the S&P 500 is outperforming the index itself.
There is a number buried in this earnings season that deserves more attention than it's getting. For the first time in four years, the average stock in the S&P 500 is outperforming the index itself. Not Nvidia. Not Apple. The average stock. The one that doesn't have a keynote and a cult.
This matters because the story of the last three years was concentration risk dressed up as a bull market. Seven names carried everything. The other 493 were passengers. When a rally is that narrow, it isn't a rally — it's a bet. And bets, eventually, get called.
What's changed is earnings breadth. Energy companies inside the S&P 500 posted a 42.5% revenue gain in the second quarter — the Iran war premium hitting income statements with full force. But the rotation runs deeper than oil. Industrials, financials, mid-caps: sectors that spent three years being ignored by capital flowing into AI megacaps are now printing numbers. Sales growth across the index is at a near five-year high. That's not one sector. That's an economy selling things.
The mechanism is simple once you see it. When money is cheap and narratives are strong, capital concentrates. When rates stay elevated and the narrative becomes crowded, capital rotates. We are in the rotation. The question is whether it holds — and the answer comes from the inflation print due this week. If US CPI cools enough to cement September Federal Reserve rate cut bets, the rotation deepens. Small and mid-caps breathe. Credit loosens at the margin. If inflation surprises to the upside, the Fed stays frozen and the broadening stalls.
My call: the broadening is real, not a head-fake. The earnings data is too wide, too consistent across sectors to be noise. But I hold it loosely pending the CPI print. The two scenarios where I'm wrong — inflation reaccelerates on energy pass-through, or the Bank of Japan tightens faster than expected and triggers a global carry unwind. Tokyo is already signalling more rate rises than markets have priced. Watch that thread.
Warren Buffett, for his part, has made his own call visible. Berkshire Hathaway has started deploying its nearly $400 billion cash pile — into its own stock. Buybacks are the signal of a man who sees nothing cheaper than what he already owns. That is either discipline or exhaustion. I read it as discipline. When the most patient investor alive stops waiting, something in the landscape shifted.
For anyone in Malta holding a pension fund or a unit-linked policy with S&P 500 exposure, the message is this: the index you own just got healthier. A rally with 493 participants is more durable than one with seven. Check your Malta pension calculator and your allocation. The composition of the next leg up will look different from the last one.
