Detailed Explanations
Stock ETFs
Stock ETFs invest in a diversified portfolio of stocks, allowing investors to gain broad market exposure or target specific sectors. They are traded like regular stocks on exchanges and provide benefits such as liquidity, low costs, and tax efficiency.
Mathematical Model:
A simple model for the value of a Stock ETF can be represented as:
- \( V_{\text{Stock ETF}} \) is the value of the ETF.
- \( w_i \) is the weight of the i-th stock in the ETF.
- \( P_i \) is the price of the i-th stock.
Commodity ETFs
Commodity ETFs provide exposure to commodities, either through direct physical holdings or futures contracts. They help investors diversify their portfolios and hedge against inflation.
Mathematical Model:
For futures-based Commodity ETFs, the value can be modeled as:
- \( V_{\text{Commodity ETF}} \) is the value of the ETF.
- \( f_j \) is the quantity of the j-th futures contract.
- \( F_j \) is the price of the j-th futures contract.
