Short Put Vs Box Spread (Arbitrage) Options Trading Strategy Comparison

Short Put works well when you're Bullish that the price of the underlying will not fall beyond a certain level.

Being risks free arbitrage strategy, this strategy can earn better return than earnings in interest from fixed deposits. The earning from this strategy varies with the strike price chosen by the trader. i.e. Earning from strike price '10400, 10700' will be different from strike price combination of '9800,11000'.

The long box strategy should be used when the component spreads are underpriced in relation to their expiration values. In most cases, the trader has to hold the position till expiry to gain the benefits of the price difference.

Note: If the spreads are overprices, another strategy named Short Box can be used for a profit.

This strategy should be used by advanced traders as the gains are minimal. The brokerage payable when implementing this strategy can take away all the profits. This strategy should only be implemented when the fees paid are lower than the expected profit.

When you are expecting the price or volatility of the underlying to increase marginally.

The market view for this strategy is neutral. The movement in underlying security doesn't affect the outcome (profit/loss). This arbitrage strategy is to earn small profits irrespective of the market movements in any direction.

• Sell Put Option

A short put strategy involves selling a Put Option only. So if you see that the shares of a Company A will not move below a 1000 then you sell the Put Option of that stock at 1000 and receive the premium amount. The premium received will be the maximum profit you can earn from this deal. However, if the price of the underlying moves below 1000 than you will incur losses.

• Buy Call Option 1
• Sell Call Option 2
• Buy Put Option 1
• Sell Put Option 2 (2>1)

Say for XYZ stock, the component spreads are underpriced in relation to their expiration values. The trader could execute Long Box strategy by buying 1 ITM Call and 1 ITM Put while selling 1 OTM Call and 1 OTM Put. There is no risk of loss while the profit potential would be the difference between two strike prices minus net premium.

There is no limit to losses incurred in the trade. The risk is when the price of the underlying falls, and the Put is exercised. You are then obliged to buy the underlying at the strike price.

The Box Spread Options Strategy is a relatively risk-free strategy. There is no risk in the overall position because the losses in one spread will be neutralized by the gains in the other spread.

The trades are also risk-free as they are executed on an exchange and therefore cleared and guaranteed by the exchange.

The small risks of this strategy include:

1. The cost of trading - Some brokers charges high brokerage/fees, which along with the taxes could make the overall loss-making trade.
2. The box spread can be liquidated by an offsetting transaction easily and transparently on an exchange with minimal loss/profit.

The profit is limited to premium received in your account when you sell the Put Option.

The reward in this strategy is the difference between the total cost of the box spread and its expiration value. Being an arbitrage strategy, the profits are very small.

It's an extremely low-risk options trading strategy.

Underlying doesn't go down and options remain exercised.

Underlying goes down and options remain exercised.

It allows you benefit from time decay. And earn income in a rising or range bound market scenario.

1. This is an Arbitrage strategy. This strategy is to earn small profits with very little or zero risks.

It is a high risk strategy and may cause huge losses if the price of the underlying falls steeply.

1. It's a professional strategy and not for retail investors. The opportunities are closely monitored by High-Frequency algorithms. These arbitrage opportunities are usually for the high-frequency algorithms and need large pools of money to make it worth it and usually with better brokerage commission schemes.
2. This strategy has high margin maintenance requirements and in many cases, the trader won't have the margin available to do that.
3. For retail investors, the brokerage commissions don't make this a viable strategy. Only low-fee traders can take advantage of this.
4. In theory, this strategy sounds good but in reality, it may not as profits are small.
5. Locking the box - Trader has to wait until to expiry by keeping the money stuck in the box.
