Voya Machine Intelligence: Welcome to the Third Wave of Investing
Imagine if we could combine the depth of fundamental analysis with the breadth of quant research—and turbocharge it with machines that can make faster, smarter decisions. We call this Voya Machine Intelligence (VMI), applying machine learning to investment decisions, enhanced with human insight and traditional quant methods.
Voya Machine Intelligence Value Proposition
We believe in our ability to deliver consistent outperformance with high active share and low correlation to equity markets resulting in high idiosyncratic alpha.
We bring machine intelligence to fundamental equity investing: combining the depth and rigor of fundamental investing with the breadth of quant and scalability of Artificial Intelligence (AI).
