In this episode of Talk ETFs, Sumit Roy sits down with Aniket Ullal, head of ETF research & analytics at CFRA, to unpack the quiet revolution happening in how exchange-traded funds are categorized and analyzed.

Gone are the days when style boxes and traditional sectors told the whole story. Today’s ETF landscape is shaped by fee-based advice models, cross-sector megatrends like AI and new product categories like buffered and single-stock ETFs.

Aniket explains why thematic and factor-based classifications are taking center stage—and how investors can use modern screening tools to better align their portfolios with real-world market forces.
