When AI Meets Politics: Darwin and the TACO Trade
Markets Expected to Drop – So Did Darwin
In May 2025, Darwin's UMAi portfolios responded to tariff threats by reducing exposure to high-risk assets. As designed, the models prioritized risk control — and underperformed the surging market.
Instead of correcting, the market rallied. Why?
Enter the TACO Trade — short for “Trump Always Chickens Out.” It was coined by Financial Times columnist Robert Armstrong. Just a light-hearted note here — the term is meant to describe a recognizable market pattern and isn’t a political statement. We don't take political sides, and our tacos are always served without bias.
This pattern sees sharp rhetoric spooking markets, only to be followed by walk-backs that reverse losses. And this time, the relief rally left Darwin looking cautious and under-performing for the month.
But that’s not a mistake. That’s by design.
Visualizing Fear, Greed, and Discipline
Let’s explore this with a scatter plot showing UMAi Growth portfolios' performance vs. the benchmark (S&P 500):
Each dot represents a month. Red dots — like May 2025 — show market gains with portfolio underperformance. While they can sting, they are the necessary price for the green dots — where Darwin holds up or outperforms during drawdowns.
The red dots represent “chickening out” — the model pulling back in the face of elevated risk. It’s the same instinct that leads to green dots: resilience during chaos.
This is the heart of risk management. You don’t just try to win. You avoid losing badly.
Timeline View: Why Smooth Returns Require Tradeoffs
Now look at the long-term view:
The top chart shows UMAi Growths' relative monthly performance — green bars for outperformance, orange for underperformance. The bottom chart shows the theoretical cumulative returns since inception — UMAi Growth (blue) vs. SPY (black).
Notice the lower drawdowns? That’s Darwin “chickening out” in riskier months. And here’s the core insight:
You can’t ride a roller coaster that only goes up.
A smoother ride mathematically requires underperformance during euphoric runs.
This tradeoff allows Darwin to sidestep large losses, resulting in steadier long-term growth — without the emotional whiplash of the broader market.
The Psychology of Investing Under Pressure
Behavioral finance gives us the real story:
-
Investors panic during drawdowns (fear),
-
Chase rallies (greed),
-
And blame models for underperformance (self-serving bias).
Darwin sidesteps these traps by managing risk, not emotion. That discipline means sometimes missing a rally — but also means avoiding disaster.
May 2025 was a test of nerves. And Darwin passed, even if it didn’t “win” the month.
Final Takeaway
Darwin’s investment philosophy is simple:
-
Win by not losing.
-
Accept the red dots as the price of earning the green ones.
-
Focus on consistency, not drama.
Because over time, success doesn’t come from reacting faster. It comes from falling less, climbing steadily, and finishing stronger.
