The Market Just Pulled Off a Miracle. Don't Get Cocky.

---

Two weeks ago, the S&P 500 was down 7% for the year. By Friday, it hit 7,126—a new all-time high.

That’s not a correction. That’s a resurrection. And frankly, it’s the kind of move that makes veteran traders nervous.

Let me be direct about what just happened: The market went from “we’re in trouble” to “we’re fine, actually” in the span of five trading days. That’s not how healthy markets typically operate. Healthy markets price things gradually. They reflect information over time. They don’t swing 11 percentage points in either direction on basically the same macro backdrop.

When One Stock Is Holding Up the Whole Index

Here’s where it gets weird. The Dow opened Tuesday up 400 points. By mid-morning, that gain was cut to 200 points. And the only reason it wasn’t negative? UnitedHealth was basically responsible for more than 200 of those points by itself.

One company. One stock. That’s your index performance.

UnitedHealth’s been on a tear because the company says its turnaround “has a long way to go” while simultaneously beating earnings and making $1.5 billion in AI investments. The market apparently loves contradictions. The stock rips higher on the promise of improvement while the company’s telling you there’s still tons of work ahead. That’s not confidence—that’s desperation for a narrative.

Meanwhile, 3M also beat earnings estimates, and the stock rose. Good news, right? Except the headline itself basically admits that beating earnings “hasn’t always helped the stock.” In other words, the market’s been skeptical of 3M’s recovery story for months. One beat doesn’t erase that skepticism. It just temporarily pauses it.

This is what a market built on fumes looks like. You’re not getting broad-based strength across the index. You’re getting a handful of names doing the heavy lifting while the rest of the market tags along.

The Iran Wildcard Nobody’s Pricing In

Here’s the thing nobody’s talking about: Trump said Tuesday he was “surprised by the resiliency of the stock market amid the Iran conflict.” He thought the Dow would be down 20%.

Let that sink in. The President of the United States expected a 20% drawdown in equities because of an active military conflict in the Middle East, and he’s shocked we’re instead printing all-time highs.

Now Trump’s also saying he expects a “great deal” with Iran and that the conflict—which began in late February—will end soon. I think he’s being optimistic about his negotiating chops. But what I know for certain is that markets have completely priced out the geopolitical risk from this situation. If talks break down? If there’s an escalation? You’re looking at a reflexive sell-off that could get ugly fast.

The market’s holding its breath on Iran the way a high-wire walker holds their breath midway across. One gust of wind changes everything.

The Tariff Trap Nobody’s Escaped

Then there’s the tariff situation, which is actively blowing up in slow motion.

Trump’s unhappy—no, “not happy”—that the Supreme Court ruled his IEEPA tariffs were illegal and wouldn’t let him keep the money already collected. His response? He’s basically saying he’ll remember which companies don’t seek refunds. That’s not economic policy. That’s a protection racket dressed up as trade strategy.

UPS and FedEx have started filing for tariff refunds, but here’s the beautiful part: those funds could take months to arrive. So companies are out the cash flow now, waiting for reimbursement later, all while navigating an uncertain tariff landscape going forward. That’s a tax on working capital at exactly the wrong time.

My read is that Trump’s tariff agenda is going to create a persistent tax on corporate earnings that doesn’t show up in the headline numbers but absolutely shows up in operational efficiency. Companies that can pass costs to consumers will survive. Everyone else gets margin-squeezed. Guess which category most of the market sits in.

What Actually Matters Right Now

I think the market’s conflating two completely different things: earnings beats and structural health. UnitedHealth beat. 3M beat. Great. But individual earnings beats in a period where the Fed’s still holding rates higher for longer, tariffs are creating uncertainty, and geopolitical risk is elevated—those don’t equal a sustainably bullish market.

The S&P 500 erasing a 7% loss in one week is a volatility move, not a valuation reset. We haven’t had time to think through what higher-for-longer rates mean for 2025 and 2026 earnings. We haven’t had time to model out the actual impact of tariffs on operating margins. And we’re absolutely not factoring in any real probability of escalation in Iran.

What we’re doing is exactly what we did in January 2022 before things fell apart again. We’re finding reasons to buy. We’re celebrating beats. We’re ignoring the structural stuff that actually matters.

Here’s my genuine uncertainty: I don’t know if this is the beginning of a real bull market or a bull trap that lasts another two weeks before reality reasserts itself. The S&P hitting a new all-time high feels bullish. But it was up 4% on the year barely five days ago after being down 7%. That kind of whipsaw typically precedes more whipsaws, not stability.

What I’m Watching

UnitedHealth’s weight in the Dow. If that stock rolls over, the entire Dow narrative collapses. Watch for any negative commentary on Medicare Advantage enrollment or AI investment payoff timelines. A 5% drop in UnitedHealth would take 100+ points off the Dow instantly.

Iran escalation triggers. Specifically, any airstrikes, drone attacks, or rhetorical escalation from either side. The market’s priced in peace. It hasn’t priced in anything worse. We’re one headline away from a sharp 3-5% pullback if things heat up again.

Tariff refund processing timeline. The government said refunds could take months. If companies start disclosing in earnings calls that cash flow headwinds are worse than expected because refunds haven’t arrived, that’s your signal the tariff impact is becoming real and measurable. Watch Q1 earnings calls in late April for this.

Rotation signals out of mega-cap. If this rally’s real, you should see breadth expand and mega-cap concentration ease. If it’s fake, you’ll see the same names carrying the load while everything else stagnates. Check the percentage of S&P 500 gains coming from the top 10 names each week. Above 80%? Still fake rally.

The market just pulled off something impressive. But impressive and sustainable aren’t the same thing. And in a market where one stock is holding up an entire index, I’m more interested in what breaks next than what’s working now.
