ETF Size: Mega-Cap ETFs, or Exchange Traded Funds, are a type of investment vehicle that allows investors to buy a basket of assets in a single fund. ETFs can track any number of underlying assets, including stocks, bonds, and commodities. One popular type of ETF is the Mega-Cap ETF, which invests in the stocks of large-cap companies. Mega-Cap ETFs offer exposure to some of the largest and most stable companies in the world. These ETFs tend to be less volatile than small-cap or mid-cap ETFs, and they often offer higher dividend yields. However, Mega-Cap ETFs may underperform during periods of market growth. Investors who are looking for stability and income may find Mega-Cap ETFs to be a good choice.
