A type of option arbitrage in which both a bull spread and a bear spread are established for a near-riskless position. One spread is established using put options and the other is established using calls. The spread may both be debit spreads (call bull spread vs. put bear spread) or both credit spreads ( call bear spread vs. put bull spread). Break-Even Point is the stock price (or prices) at which a particular strategy neither makes nor loses money. It generally pertains to the result at the expiration date of the options involved in the strategy. A "dynamic" break-even point is one that changes as time passes.
Spread: A trade in which two related contracts/stocks/bonds/options are traded to exploit the relative difference in price change between the two. A trading strategy in which a trader offsets the purchase of one trading unit against another.
