An offer from one company to buy shares of stock of another company from that other company's existing stockholders. Those stockholders are asked to "tender" (surrender) their shares for a specific price (represented by cash, shares in another company, or both), which is usually higher than the current market price of the stock.
An estimated price of a call or put derived from a mathematical model, such as the Black-Scholes or binomial models.
An approximation of the decrease in the price of an option over a period of time when all other factors are held constant. Theta is generally expressed on a daily basis. For example, if a call has a price of $3.00 and a theta of 0.10, one day later, with all else unchanged, the call would have a price of $2.90 ($3.00 - (.10 x 1)). Generated by a mathematical model, theta depends on the stock price, strike price, volatility, interest rates, dividends, and time to expiration.
