# Bottom Straddle (Put and Call, Writing method)

The **Bottom Straddle** is formed when trader writes put options and the same number of call options with the same strike price on the underlying asset.

## Bottom Straddle

Let us assume that the trader writes puts and calls with strike price K_{1}. In this method, the trader will enjoy cash inflow from writing options, unlike the Top Straddle. The presumption is all options should expire on the same time.

(compute based on: options volatility 54%, risk free rate on options 10%, K $55, K_{1} $55, period 6 months, present value of initial cashflow neglected, equity)

Let us assume C_{1} be write price of call option with underlying strike price K_{1}, P_{1} be write price of put option with underlying strike price K_{1}. The assumed price of underlying asset is at K_{1}.

### Bottom Straddle

Profit Table

Initial Cash Outlay = C_{1} + P_{1} (C_{1} > P_{1} )

Underlying Price Range | Payoff from Short Call Option at K_{1} strike |
Payoff from Short Put Option at K_{1} strike |
Total Payoffs |

S_{T} ≤ K_{1} |
0 | – (K_{1} – S_{T }) |
C_{1} + P_{1}-(K_{1} – S_{T }) |

S_{T} > K_{1} |
-(S_{T} – K_{1}) |
0 | C_{1} + P_{1}– (S_{T} – K_{1} ) |

In the model of Bottom Straddle using cash inflow method, the trader has opinion that the underlying price will remain close to K_{1 }so that there will be a profit.

The Bottom Straddle can be viewed as a profit capped trade as profit is limited to C_{1} + P_{1}. Alternatively, the Bottom Straddle is a low reward high risk trade because loses are unlimited when price of underlying moves up; and loss up to price of underlying up less selling price of to a maximum of K_{1} if prices of underlying dropped.

This trade is a form of volatility trade as the stock price is not expected to move away from K_{1}. There is another volatility trade that will yield greater returns with lower cash outflow. However, it will be a lower probability event because the expected volatility is required to be much higher than the Straddle.
