There's a scene in Joker where Arthur Fleck says: "The worst part of having a mental illness is people expect you to behave as if you don't." Yeah. The worst part of trading the American market in 2025 is that people expect you to behave as if everything's normal.

It's not.

What happened, no sugarcoating

The Dow Jones tanked over 500 points on a Friday that started bad and ended worse. Two simultaneous triggers — because the market loves a one-two punch:

First: Donald Trump opened his mouth about oil. The president's comments sent crude soaring, and when oil spikes like that, out of nowhere, for geopolitical reasons, the market goes into full panic mode. This isn't the kind of rally that feeds oil company profits — it's the kind that feeds inflation. And inflation is the forbidden word of 2025, the Voldemort of the Federal Reserve.

Second: February's jobs data came in with a nasty surprise. Net job losses. That's right. The market was expecting a soft slowdown, a smooth landing on a freshly paved runway, and instead got a belly flop into an empty pool.

The problem runs deeper

Look, when you combine oil surging on a presidential statement and a weakening labor market, the scenario taking shape is the one every fund manager has nightmares about: stagflation. Persistent inflation with a slowing economy.

It's the worst of all worlds. The Fed can't cut rates because inflation won't let up. It can't raise rates because the economy is already wheezing. It just sits there, paralyzed, like a goalkeeper who doesn't know which way to dive on a penalty kick and ends up watching the ball go straight down the middle.

Larry Summers had been warning about this risk. Nassim Taleb would say it's the black swan everybody saw coming but pretended wasn't black — it was "dark gray." Come on, dark gray is black, people.

The analyst circus

So you flip on CNBC — or whatever talking-head show you prefer — and what do you find? Some analyst in a tailored suit explaining that "the market is pricing in uncertainties" and that "it's time for selective caution."

Selective caution. Write that one down. It's the kind of phrase that means absolutely nothing but sounds smart enough that nobody questions it.

What these guys won't say is simple: nobody knows what Trump is going to say tomorrow. Nobody. Not even Trump himself. And when the most important market variable is the mood of a single human being on Truth Social, you don't have a market — you have a casino where the dealer changes the rules in the middle of the hand.

What this means if you've got money on the table

If you're long American stocks, take a deep breath. 500 points on the Dow isn't the end of the world — we've seen worse drops that became footnotes in two weeks.

But the pattern matters. And the recent pattern is one of rising volatility fueled by politics, not fundamentals. That's dangerous because there's no valuation model that can price in a presidential tweet.

For those trading in emerging markets: keep your eyes on oil. Petrobras dances to that tune. And the currency feels every sneeze from Wall Street like it's pneumonia.

Buffett is sitting on $300 billion in cash at Berkshire. You think that's a coincidence? The Oracle of Omaha doesn't say much, but his silence is deafening. When the most patient man in global capitalism decides to stockpile ammo instead of pulling the trigger, maybe — just maybe — it's not the time to play hero.

The question nobody wants to ask

How much longer will the global market accept being held hostage by off-the-cuff remarks from an American president who treats geopolitics like a reality show?

And more importantly: do you actually have skin in the game, or are you just parroting the last guru who popped up in your feed?

Because when the Dow drops 500 points, people with no position sleep like babies. People with one wake up at 3 a.m. staring at their phone.

Welcome to the real game.
