Efficient Trading : ETFs provide investors a convenient way to gain market exposure viz. an index that trades like a stock. In comparison to a stock, an investment in an ETF index product provides a diversified exposure to the market. Depending on the index, investors may obtain exposure to countries/ markets or sectors.
Equitising Cash : Investors with idle cash in their portfolios may want to invest in a product tied to a market benchmark like an index as a temporary investment before deciding which stocks to buy or waiting for the right price.
Managing Cash Flows : Investment managers who see regular inflows and outflows may use ETFs because of their liquidity and their ability to represent the market.
Diversifying Exposure : If an investor is not sure about which particular stock to buy but likes the overall sector, investing in shares tied to an index or basket of stocks provides diversified exposure and reduces stock specific risk.
Filling Gaps : ETFs tied to a sector or industry may be used to gain exposure to new and important sectors. Such strategies may also be used to reduce an overweight or increase an underweight sector.
Shorting or Hedging : Investors who have a negative view on a market segment or specific sector may want to establish a short position to capitalize on that view. ETFs may be sold short against long stock holdings as a hedge against a decline in the market or specific sector.
