“Joseph Plazo: Algorithms Are Powerful, But Not Principled”“Automated Trading, Ethical Blind Spots: Joseph Plazo’s Warning to Asia”“Joseph Plazo Issues Caution on AI in Finance: Human Values Still Matter”


In a session attended by students from NUS, Kyoto University, and AIM, investment strategist Joseph Plazo, issued a timely warning: in a world increasingly shaped by machines, human judgment remains essential.

From the financial heart of Southeast Asia — At the Asian Institute of Management, the conversation turned not to technology, but to ethics.

Plazo, the founder of the high-performing quant firm Plazo Sullivan Roche, is widely regarded as a leading figure in machine-driven investing.

And yet, it was not code he chose to champion—but caution.

“Delegating execution is easy. Delegating principles is dangerous.”

???? **A Technologist Who Questions the Tools He Built**

Plazo’s credibility comes not from critique, but from contribution. He has helped reshape modern investment practices through AI.


“AI is excellent at execution. But poor at explaining ‘why’.”

He recounted a key moment during the COVID-19 crash: a bot under his firm’s control flagged a short position on gold—hours before an emergency Federal Reserve announcement.

“We intervened,” he said. “The AI was technically correct, but it lacked the wider understanding.”

???? **The Importance of Human Oversight in Automated Systems**

In a reference to a 2023 Fortune roundtable, Plazo cited concerns that traders increasingly feel disconnected from the market—no longer making decisions, but following models.

“Pausing isn’t always inefficient. Sometimes, it’s responsible.”

He proposed a decision framework, which he called **“Conviction Calculus”**, grounded in three guiding questions:

- Does this move copyright the firm’s reputation?
- Have non-digital factors been considered—such as public sentiment, leadership experience, or history?
- Can we explain the reasoning behind this action—beyond algorithms?

???? **Why Joseph Plazo’s Message Resonates Across the Region**

Across Asia, investment in AI and fintech is accelerating. Countries like Singapore, South Korea, and the Philippines are becoming hubs for automated trading systems and tech-led asset management.

Plazo’s message? The pace is impressive—but governance must not be left behind.

“You can scale capital faster than character,” he said. “And that imbalance is a concern.”

In here 2024 alone, two hedge funds in Hong Kong reported billion-dollar losses due to AI-driven decisions that failed to anticipate geopolitical shifts.

“Automation doesn’t mean immunity from error.”

???? **The Next Step: Context-Aware AI**

Despite his warnings, Plazo remains optimistic about AI’s future—when developed thoughtfully.

His team is building what he described as **“narrative-integrated AI”**—tools that factor in not just financial data, but also context, tone, timing, and social dynamics.

“We need tools that understand meaning, not just movement.”

At a private gathering after his talk, his proposals attracted immediate interest from capital firms seeking long-term resilience. One described his vision as:

“A timely model for responsible innovation.”

???? **Final Thought: The Most Dangerous Errors Are the Quietest**

Plazo concluded with a sobering statement:

“Crashes won’t always be emotional. Some will be perfectly rational—and perfectly wrong.”

It was a reminder: leadership is about asking the hard questions—especially when the data says yes.

Because in the race to automate everything, what’s often lost is not just time—but responsibility.
