Build a Hedge with Options

10/24/2014 8:00 am EST


Options expert Russ Allen, of Online Trading Academy, highlights some of the virtues of hedging with options since this can help you stay in a position when that makes logical sense, because the worst-case result is known and tolerable.

In last week’s article, which you can read here, I wrote about an example of selling Put options to take advantage of what seemed to be high volatility. At the end of that article, I said that a short put position could be hedged to change its risk profile, Today, we’ll explore that further.

In that example, we looked at selling October put options at the $186 strike price with 8 days to go, for $50 per contract. Here is the price chart as it looked at the time the article was written:

The reasons for considering the short 186 puts were:

  • Implied Volatility (IV), representing the “inflatedness” of options, was higher than it had been for most of 2014, at a reading of 14.8%.
  • A swing low around $186 from early August looked as though it could very well hold for the few days until expiration.
  • If SPY did go below $186, we would be forced to buy it at that price; subtracting our $.50 per share proceeds from the put sale, our net cost would be $185.50. With the chart as it appeared then, this was a price that we would not have minded paying.

Note that I warned at the time that this was not a recommendation, just an example of how one might consider taking advantage of inflated option prices. I also showed a longer-term chart for perspective, reproduced here.

I noted that “the current IV reading of 15%, while pretty high for the last year, is nowhere near the levels that occurred in previous major drops in 2011 when it reached 39% in 2010 and worst of all in 2008 (67%)…so it’s clear here that a ‘high’ reading of IV now doesn’t necessarily mean that IV can’t go even higher.”

As it has developed, SPY dropped a huge amount and IV did in fact go quite a bit higher:

At the close on October 16, the day before expiration, SPY was at $186.27, and IV had gone from 14% to over 25%. This meant that option traders—on average—now believed that SPY could move in a range that was 25% wide, or plus or minus 46 points. The 15% IV reading, that had seemed high the week before, had now been exceeded by a long shot.

Traders had good reason to believe in increased movement going forward. On Wednesday, SPY had traded in an extreme range from $187.69 all the way down to $181.92, closing that day at $186.42.

As of Thursday, the 186 short put was now in danger of being assigned. That would happen if SPY closed even twenty-seven cents lower the next day, which was expiration day. In that case, after the Friday close we would be forced to buy SPY at $186 per share. We would have a loss to the extent, if any, that SPY was below our net cost on the following Monday morning. That net cost would be the $186 that would be extracted from our account to pay for the SPY, less the $.50 that we earlier received for selling the 186 put, or $185.50. Since SPY had gone as low as $181.92 on Wednesday, owning it at $185.50 was a little scary.

So, the question was; should we maintain the short 186 put position through expiration or buy it back?

In favor of buying back the short put:

  • SPY might be much lower than our $185.50 net cost on Monday, we would then have a loss.
  • The size of that possible loss was virtually unlimited.

In favor of maintaining the position:

  • SPY was still above the $186 strike price and might remain so, giving us our $.50 profit.
  • Since the next day was expiration day, with a large net put open interest balance, there would be upward pressure on SPY. (Option market makers sell stock, as a hedge, when they sell puts. When the hedge is no longer needed, they buy the stock back. The opposite happens with call options. If there are many more open put options than call options as expiration approaches, more stock must be bought than sold by option market makers collectively. This would add buying pressure, which could help push the stock up.)
  • Implied volatility was now much higher than when we sold the put. Buying it back now would guarantee a sizable loss. The 186 put, for which we had received $.50 on October 9, had traded at prices from $.49 to $4.82 in the last two days, and opened on Thursday at $3.66.

The price chart was ambiguous. Although SPY had broken the level around $185 that we saw as our support when we sold the puts, it had been just a brief wick down before snapping back up. Another demand level was below at around $181.

Under these circumstances, a trader might very well have decided to take loss before it got any worse and bail on the short puts. This could have been done by buying them back on Thursday, on which they traded between $.68 and $3.83.

If the trader had had a crystal ball and had been able to see that SPY would open on Friday with a large gap up and trade higher, closing at $188.47 and leaving the $186 puts to expire worthless as planned, he could have left those short puts on and slept soundly.

We, of course, do not have a crystal ball. However, we could have taken steps that could also have let us sleep better. I mentioned last week that a seller of put options can reduce his risk by hedging the position.

There are many ways to hedge a position. The most straightforward of these is simply to buy an option of the same type as the one you sold, at a different strike price, so that the second, insurance put pays off if the moneymaker—or anchor put—goes bad.

In this case, at the time we sold the Oct 186 puts at $.50, we could have bought the Oct 181 puts for $.16. This sixteen cents for insurance reduced our maximum net profit by that amount. But it also changed our maximum loss from unlimited to a finite amount of less than five dollars per share. In the best case, if SPY closed on expiration day above $186, both puts would expire worthless. We would be left with the $.34 per share difference between the fifty cents we received for the 186 moneymaker puts and the sixteen cents we paid for the 181 insurance puts.

If the worst happened, and SPY were to end on Friday much lower than 186, our loss would now be limited. If it were to close at expiration day at 180, for example:

  • The SPY would be put to us, meaning we would receive it and have to pay $186 per share, as the 186 puts were exercised and we were assigned to fulfill our obligation.
  • We would in turn exercise our 181 puts and put the stock back, receiving $181 per share.
  • Our net loss would be $186 - $181, or $5.00, less the $.34 net credit we earlier received (receiving $.50 for the 186 puts and paying $.16 for the 181 puts). The net loss would thus be $5.00 - $.34 = $4.66.
  • This is the maximum net loss we could have, no matter how low the price of SPY should go, even to zero.
  • Our return on risk for this trade would be $.34 / $4.66 or about 7% in eight days.

If a trader had chosen to hedge the unlimited risk of the short puts—by buying insurance puts as described above—he might have had the confidence to hold onto what turned out to be a winning position. This illustrates one of the virtues of hedging. It can help you to stay in a position when that makes logical sense, knowing that the worst-case result is known and tolerable.

Note that I am stretching a point here by saying that staying in this particular trade would have made logical sense. A good case can be made against that. But I hope you can see my main point, which is that our decision on whether to go or stay in a trade is a different calculation when our worst-case scenario is not a catastrophe. This can make the difference between being able to ride out a trade that turns into a winner or panicking out too soon.
