Mirae Asset Mutual Fund announced two new fund offers — Nifty Energy ETF and Smallcap 250 ETF — designed to capture opportunities in sectoral growth and market breadth expansion. The launches come amid strong inflows into equity schemes during October as investors diversified portfolios toward thematic segments. Fund managers said both ETFs aim to provide passive exposure to high-growth sectors through cost-effective index tracking. Analysts expect continued retail interest as energy and smallcap segments benefit from economic recovery and policy support.
