Types of Market Price
- Spot Price: The current price in the marketplace at which a given asset can be bought or sold for immediate delivery.
- Futures Price: The agreed-upon price for future delivery of an asset or commodity.
- Bid Price: The price a buyer is willing to pay.
- Ask Price: The price a seller is willing to accept.
- Average Price: Often used in markets with high volatility; calculated as the average of the bid and ask prices.
Detailed Explanation
Market price is determined by the dynamics of supply and demand. When demand for a good or security increases and supply remains constant, the market price tends to rise, and vice versa. Market price serves as a vital indicator for investors, consumers, and policymakers.
Black-Scholes Model
The Black-Scholes model calculates the market price of options. It uses the formula:
$$ C = S_0 N(d_1) - X e^{-rt} N(d_2) $$
Where:
- \( C \) is the call option price
- \( S_0 \) is the current stock price
- \( X \) is the strike price
- \( t \) is the time to maturity
- \( r \) is the risk-free rate
- \( N(d_1) \) and \( N(d_2) \) are the cumulative distribution functions of a standard normal distribution
