The Short Strangle strategy becomes more attractive with the volatility remaining at historically high level. Part 1 of this article describes the strategy basics, including the complex margin requirement that changes with the underlying stock movement. We’ll deal with the Short Strangle adjustments, as well as how to use Short Strangle if you are an active trader in subsequent parts of the article. If you have been investing in Money Market or Certificate Deposits, then this is the perfect strategy to at least triple your return with manageable risks.
1- The Basics
The Short Strangle is a neutral position. The investor will profit from the position if the stock stays stagnant and expires within the profitable range.
- Sell (short) out-of-the-money (OTM)
CALL(s) in a selected target month.
- Sell (short) the same number of out-of-the-money (OTM) PUT(s) for the same month.
- The maximum profit is the net credit (total premiums received).
- The maximum risk is infinite in either direction (infinite to 0 on the put side/decline).
- The position has both an upper break even and a lower break even.
- Profit is realized if the stock price remains between the upper and lower break even points.
2- Example Spread:
Since the maximum risk is infinite in either direction, the most critical factor is to select the underlying stock that doesn’t go to zero or infinite in a hurry. The best hedge is to use a basket of stocks using
ETFs. The favorites are
SPY,
DIA,
QQQQ, and IWM.
Note that margin is not usually allowed retirement accounts, so selling Short Strangle would not work well for retirement accounts.
Let’s look at a practical “Strangle a Spy” example (thanks to GabbyH, the 85 years old
PSW member for the catchy phrase)
for prices at the close of 1/9/2009:
Sell SPY Feb 70 PUT (20% downside cushion) and Sell SPY Feb 105 CALL (17% upside cushion) for $0.81 credit. For safety reason, we should have a stop in place for when SPY reaches the strikes that we sold.
- The margin requirement ATM is $8.9 for the SPY closing price of $89, meaning we need $8.9 in cash to be able to sell the Short Strangle above.
- The margin requirement increases to approximately $24.2 if SPY rallies to $105 the next day, and it also increases to $18.4 if SPY drops to $70 (See below for margin calculation rules).
- For profit calculation, let’s conservatively take the highest margin requirement of $24.2, giving us a maximum profit of 3.35% in…
