Ratio spreads involve buying one option and selling a greater quantity of an option with a more OTM strike. The options are either both calls or both puts. It is a limited profit that is taken when the options trader thinks that the underlying stock will experience little volatility in the near term.
Call ratio spreads lose money when the stock price rises sharply so will apply in sidwasy market ( elliot 4wave up wave in progressing in nature ).Call ratio spreads work best when the stock price moves to the strike price of the short call (and no higher) at expiration.It can be any ratio, but we will focus on ratio spreads created using a 2:1 ratio with 2 options sold to 1 option bought.A short call ratio spread means buying one call (generally an at-the-money or otm call) and selling two calls at the same expiration but with a higher strike.
The combined Vega of the two short calls will generally be much greater than that of the single long call.
