Weekly options have become increasingly popular in recent years. In this chapter, we’ll be looking at how to trade double butterflies using weekly options.
Using double butterflies to trade weekly options can work really well if you like the idea of a “set and forget” strategy. With short-term butterflies you can enter trades relatively cheaply, particularly if you move further out-of-the-money. By using a double butterfly, you don’t care which way the underlying moves, as you are creating profit zones to the upside and downside.
To set up the trade, you place a call butterfly spread above the current market price and a put butterfly spread below the current market price. A good guide is to have your short strikes centered just outside a 1 standard deviation move in the underlying instrument. I like to initiate the trade anywhere between 7 and 10 days to expiry.
Generally this will be fairly cheap to set up. The reason I called this a “set and forget” strategy, is that once you put on the trade, you leave it until expiry (note you should only do this with European style Index options). This helps reduce commission costs and slippage as there is no exit for the trade. As the trade is cheap to set up, you are willing to accept a 100% loss on the trade.
Here’s an example of how you set up this trade:
Date: August 6th 2013,
Current Price: $1698
Trade Details: SPX Weekly Double Butterfly
Buy 1 SPX Aug 15th $1625 put @ $0.80
Sell 2 SPX Aug 15th $1650 puts @ $1.80
Buy 1 SPX Aug 15th $1675 put @ $4.80
Premium: $200 Net Debit
Buy 1 SPX Aug 15th $1725 call @ $1.60
Sell 2 SPX Aug 15th $1750 calls @ $0.35
Buy 1 SPX Aug 15th $1775 call @ $0.10
Premium: $100 Net Debit
Total Premium: $300 Net Debit
At the time of trade entry, a 1 standard deviation move would have put SPX at 1665 or 1731 at expiry.
Here’s how the profit diagram looks. Note that the trade is risking very little capital and there are two very nice profit zones to the upside and downside. You will profit anywhere between -4.10% to -1.50% and +1.80% to +4.30%. If you got lucky and SPX settled at 1650 or 1750, you would collect a nice profit of $2,200.
SPX ended up settling at 1657 for the August 15th expiry. The call butterfly expired worthless resulting in a loss of $100 while the put butterfly made a profit of $1600 thanks to the long 1675 put and short 1650 puts. Overall the trade made $1500 in profit for a return of 500%.
This won’t happen every week of course, but this is a nice profit for a low stress, inexpensive trade. You only need to a have a winning trade every few weeks to make it worthwhile.
You can also increase your chances of success by waiting for 1-2 quiet weeks of less than 1% movement before initiating the trade. This gives you a greater chance that the index will move the required 1 standard deviation.
