No one expected Joseph Plazo’s TEDx session to dismantle the last remnants of the Wall Street mythos—but that’s exactly what he did.
Drawing on data from Plazo Sullivan Roche Capital, he showed that algorithms now dominate more than 80% of global market volume, rendering human decision-making largely ceremonial.
1. The Death of the Trading Floor
He pointed out that while humans still “monitor,” algorithms now act.
2. Why Institutions Chose Algorithms
Plazo shared that within Plazo Sullivan Roche Capital, algorithmic systems outperform human traders consistently across risk metrics, slippage, execution cost, and bias elimination.
3. The Rise of Algorithmic Ecosystems
He described how these systems now manage everything from order execution to risk balancing—often with zero human intervention.
Why Most Humans Are Trading Against Machines
Yet, he also offered hope: humans can win—not by being faster, but by understanding how these systems think, move, and rebalance.
What the Audience Never Expected
As Joseph Plazo concluded, he left the crowd with a message that resonated long after the applause faded:
“Human intuition isn’t dead. But in today’s markets, intuition must check here be paired with algorithmic understanding—or it will be crushed by it.”
His TEDx talk didn’t just explain the last decade of change—it armed the public with the truth behind modern trading.
And for many, it was the wake-up call they never saw coming.
