New Delhi: The fifth tranche of the Central Public Sector Enterprises (CPSE) Exchange Traded Funds (ETFs) will be launched for subscription on Tuesday for anchor investors, where the government will seek to raise at least Rs 3,500 crore. Non-anchor investors can submit their bids from Wednesday to Friday. Since the fund is concentrated and susceptible to high volatility, first-time retail investors and long-term equity mutual fund investors must keep away from thematic funds even with low valuations and the discount on offer, according to financial planners.
