Guggenheim Partners has made a surprising return to the exchange-traded fund (ETF) market, despite having sold their ETF business several years ago. Eric Balchunas, senior ETF Analyst at Bloomberg Intelligence, posted on X. This move indicates a possible reassessment of the ETF market's potential and dominance, which may have been underestimated by the firm in the past. Guggenheim's reentry into this sector suggests a renewed interest in capitalizing on the growing popularity and influence of ETFs in the financial industry.
