Typical Strategy Groups with Three Legs
Three main groups of strategies with three legs include ladders, call and put butterflies, and covered straddles and strangles.
Ladders are typical examples of three-legged strategies. They are like vertical spreads with an additional leg – usually out of the money and always of the same type (call or put) as the other options.
The call and put butterflies are sometimes considered to have four legs, because the middle strike has double position size. But in fact, they only involve three different strikes and three different options, so three legs is more correct.
Covered Straddles and Strangles
Short straddle or strangle can be hedged by adding a long underlying position, which eliminates the unlimited risk in case of upside underlying price move (just like a short call is hedged by long underlying in covered call). These strategies are called covered short straddle (or strangle) and have three legs – two legs from the straddle or strangle, plus the underlying position.
