Crossing the Rubicon

Positioning is back to FOMO, earning breadth is a mirage, and the macro regime is quietly flipping under everyone’s nose.

I was initially going to write a long post recounting what happened, how we got there, and why the market did what it did. I’m going to spare you. Everyone who has a Twitter feed, or a pulse knows the rough contours of the Iran–US war already. What actually matters is what the event revealed about the market.

I called this piece Crossing the Rubicon for a very specific reason. I think we are within a week or two of passing the event horizon on the physical oil situation. Past that point, there is no smooth way back. Very soon, flights will start getting canceled en masse because refiners simply don’t have enough jet fuel in the system. Not long after, you’ll see dry pumps at gas stations, first in the weaker logistical corridors and then everywhere. This is a physical inventory and throughput problem that plays out on a timeline measured in days and weeks, not quarters.

That is the Rubicon. Once those lines are crossed, the market stops pricing an “Iran war premium” and starts pricing a structural supply regime.

The Playbook Worked, On the Surface

The Iran–US war followed the traditional playbook of any past geopolitical event: the S&P 500 corrected for a few weeks, then recovered.

What actually struck me was the positioning.

Real money and long-only funds were incredibly sticky. They didn’t sell anything. They diamond-handed their positions through the thick and thin of it, all the way down and all the way back up. There was no capitulation from the bigger, slower hands.

The fast money did the opposite. CTAs flipped from max long to max short in an almost manic fashion, then had to chase it all the way back up once the ceasefire held. The positioning snapshots for systematic funds told the story loud and clear: a full round-trip in a matter of weeks.

That’s the first clue. When the marginal buyer on the way up is a CTA covering shorts, and the slow money never actually left, you haven’t cleansed positioning properly. Instead you have set the table for a speculative rally.

Everyone Is Back Long

Positioning is back to very full long, and FOMO is everywhere around me.

The data backs it up:

• AAII sentiment is max bullish over a one-year window. Bears are capitulating.

• The SPX call/put ratio is stupidly low.

• The SPX skew is highly tilted toward calls. Traders are hoarding calls because they’re afraid of missing the right tail.

• The Goldman sentiment indicator is back to firmly positive.

Every one of these is a sentiment-and-positioning alarm bell. Individually, you can dismiss them. Stacked on top of each other, they paint a picture of a market that has already priced the good outcome, and is now paying up for more of it.

The Cheap Market That Isn’t

I get the bull case. Fundamentally, the SPX was genuinely cheap during the war. Forward earnings kept rising while price corrected, and the forward P/E mechanically compressed from both sides: numerator going down, denominator going up. That’s the kind of setup that normally rewards buyers.

But there’s a big misconception here.

Forward earnings have been going higher on the back of extraordinarily narrow breadth. Roughly 50% of the earnings rise is coming from a single name, Micron. The rest is coming from energy. These are rough numbers, but they check out when you decompose the index.

Two things jump out:

1. The leadership is very, very narrow. A one-stock earnings engine is not a healthy market.

2. Energy-driven earnings leadership is bad leadership. Historically, when energy carries index earnings, the usual reason is that input costs are squeezing every non-energy sector on the other side of the P&L.

A rising forward earnings number looks bullish in a headline. Under the hood, it’s telling you where the pain is about to show up.
