War Thursdays and the Market's New Routine of Terror

---

The S&P 500 has developed a neurosis.

Every Monday, traders show up caffeinated and optimistic. Tuesday brings more of the same measured confidence. Wednesday? Still hanging in there. Then Thursday arrives like a recurring nightmare, and the index face-plants with the reliability of a Swiss timepiece.

Five weeks into this Middle East war, and we’ve got ourselves a genuine market pattern that would make a behavioral psychologist rich. Bloomberg’s tracking shows it clear as day: the S&P 500 starts strong each week, drifts sideways mid-week, then collapses every Thursday and Friday like it just remembered there’s actual shooting happening in the Persian Gulf.

This isn’t your grandfather’s war market. This is something new and weird.

The Clockwork Panic

I’ve seen markets react to geopolitical events for two decades, but this weekly rhythm feels different. Usually, war news hits and markets either crater immediately or they don’t. The delayed reaction pattern we’re seeing suggests something more complex than simple fear.

My read? Modern algorithmic trading has created a feedback loop where weekly options expiration anxiety meets geopolitical uncertainty. Thursday has become the day when all the week’s suppressed anxiety gets purged through the system like a financial colonic.

When Trump stepped up this week and declared the U.S. would hit Iran “extremely hard” over the next 2-3 weeks, the pattern held. Asian markets tanked. European stocks plunged. U.S. futures fell. Oil jumped more than 6% as Brent crude surged on escalation fears.

But here’s what caught my attention: the reaction was swift but not panicked. Markets have gotten used to this dance. They know the steps now.

Oil’s Wild Ride and the EV Paradox

The energy sector is having its moment, and it’s exposing some fascinating contradictions in how we think about market disruption.

Brent crude surging 6% on Trump’s Iran threats? Expected. Oil gaining in volatile trading as the president suggested the conflict would last another two to three weeks? Textbook geopolitical premium.

But here’s where it gets interesting: various car selling platforms are reporting a sharp increase in consumer interest for electric vehicles since the Middle East crisis began. At the exact same time that auto giants are pivoting back to combustion engines.

Talk about mixed signals.

The EV demand spike makes perfect sense from a consumer psychology standpoint. Gas prices threaten to spike, people start thinking about alternatives. It’s the same reason Toyota couldn’t keep Priuses on the lot during the 2008 oil crisis. But the timing is almost comedically bad for automakers who’ve been quietly backing away from their electric commitments as battery costs stayed high and charging infrastructure remained spotty.

Healthcare’s Quiet Outperformance

While everyone’s fixated on oil prices and war drums, healthcare stocks have been putting together a surprisingly decent performance. The sector has dropped just 1.1% over the past six months compared to the S&P 500’s 2.8% decline.

That’s not flashy, but in this market, boring outperformance is worth paying attention to. Healthcare companies driving medical advancements have benefited from elevated demand, and the sector’s defensive characteristics are showing through as geopolitical uncertainty rattles other industries.

Three healthcare stocks have open questions worth investigating, according to recent analysis. From novel pharmaceuticals to telemedicine, most healthcare companies are on a mission to drive better patient outcomes, and that mission is translating to relative market strength.

I think this quiet outperformance is telling us something about where smart money is positioning for uncertainty. When you don’t know if we’re heading into a broader Middle East conflict or a resolution in the next few weeks, you buy things people need regardless of what happens. Healthcare fits that bill.

The Services Sector Bloodbath

If healthcare is the quiet winner, business services stocks are getting absolutely massacred. The sector has shed 7.6% over the past six months, significantly worse than the broader market’s 2.8% decline.

The reasons are straightforward but brutal: AI-driven disruptors are eating their lunch while corporate budgets tighten. Business services providers built their models on using specialized expertise to help enterprises streamline operations and cut costs. But what happens when AI can do a lot of that specialized work for pennies on the dollar?

The answer is what we’re seeing: a slow-motion sector collapse as investors realize many of these companies are facing existential threats, not cyclical headwinds.

This is where I’d be extremely careful. One services stock might be worth researching further, but two others are questionable at best. The problem is telling the difference between companies that can adapt to the AI revolution and those that are about to become roadkill.

Trump’s Mystery Money and Market Confidence

Here’s a weird detail that’s getting overlooked: Trump is paying TSA agents from unspent funds in last year’s tax and spending bill, but nobody seems to know exactly where this money is coming from.

That should concern markets more than it apparently does.

When a president starts moving money around without clear Congressional authorization to keep essential services running, it usually signals deeper fiscal dysfunction. But markets are so focused on the Iran situation that this potential constitutional crisis is flying under the radar.

My worry is that we’re going to wake up in a few weeks to discover the federal government’s financial situation is more precarious than anyone realized, just as we’re potentially escalating a Middle East conflict that could send oil prices through the roof.

What This Pattern Tells Us About Modern Markets

The Thursday panic pattern reveals something uncomfortable about how markets work in 2024. We’ve created a system where human psychology meets algorithmic amplification in ways that produce regular, predictable breakdowns.

It’s like having a car that runs perfectly six days a week but the engine explodes every seventh day. You can plan around it, but it’s still a problem.

The pattern also suggests markets aren’t pricing in the war as an existential threat to global stability. If they were, we’d see sustained selling pressure, not this weird weekly rhythm. Instead, it feels like markets are treating geopolitical risk like a utility bill: unpleasant but manageable, something you deal with on schedule.

That complacency might be justified. Or it might be setting us up for a much bigger shock when the real disruption comes.

The Sector Rotation Nobody’s Talking About

While everyone watches oil and defense stocks, there’s a quieter rotation happening that could be more significant long-term. Money is moving toward defensive sectors like healthcare and away from anything that looks vulnerable to AI disruption or economic slowdown.

This isn’t the dramatic sector rotation that makes headlines. It’s more like water finding the cracks in a sidewalk. Slow, persistent, and ultimately more destructive than obvious forces.

The services sector collapse is just the beginning. Any industry built on information arbitrage or specialized human knowledge is going to face similar pressure over the next few years. Markets are starting to price that in, sector by sector.

Healthcare’s outperformance suggests investors understand this dynamic. You can’t AI your way out of needing medical care, at least not yet. But you can definitely AI your way out of needing a lot of business consulting services.

The Real Risk Everyone’s Missing

Trump’s timeline for the Iran conflict — two to three weeks — creates a specific window of maximum danger for markets. Not from the conflict itself, but from what happens if it doesn’t end on schedule.

Markets have internalized this timeline. They’re planning around it. If week three turns into week four, then week five, we’ll see the kind of sustained selling pressure that makes the Thursday panics look quaint.

The bigger issue is that markets are operating on presidential timeline guidance for a military conflict. That’s not how wars work. They have their own logic, their own momentum. When market expectations crash into military reality, the results are usually ugly.

I’m also watching for signs that the federal government’s creative financing for basic operations starts affecting market confidence. If paying TSA agents requires mysterious fund transfers, what happens when we need to finance an actual war?

The EV-Oil Contradiction Resolved

The apparent contradiction between rising oil prices and increasing EV interest isn’t actually a contradiction at all. It’s the market working exactly as it should.

Higher oil prices make EVs more attractive to consumers, which increases demand, which should theoretically accelerate EV adoption. But automakers are pivoting away from EVs just as consumer interest spikes, which means supply constraints could keep EV prices high and adoption slower than optimal.

This creates opportunities for companies positioned correctly and problems for those caught on the wrong side. Tesla deliveries, due soon, will give us a real-time read on whether consumer interest is translating to actual purchases or just wishful thinking.

What I’m Watching

• Thursday at 2 PM EST: The exact time when weekly panic selling typically begins. If we break this pattern even once, it could signal a fundamental shift in how markets are processing war risk.

• Brent crude at $85: If oil pushes through this level and holds, we’re looking at sustained inflationary pressure that could force the Fed’s hand on rate policy, war or no war.

• Healthcare sector relative strength vs SPY: As long as healthcare stocks outperform the broader market by more than 100 basis points monthly, defensive positioning is working and smart money expects continued uncertainty.

• Tesla Q4 delivery numbers: Due any day now, these will tell us whether EV demand surge is real or just survey noise. Anything above 500,000 units suggests the war-driven EV interest is translating to actual sales.

The market’s developed a routine around this war, complete with scheduled panic attacks every Thursday. But routines have a way of breaking when you least expect them to.
