Monday, 12/15
Goldman Sachs (GS) comes out with earnings tomorrow morning and I thought it might be a good opportunity to sell volatility ahead of earnings. With the historical volatility currently at 122 and the IV at about 100, this high volatility allows us to collect more premium than in a more normal, low volatility environment. Also, being that this is options expiration week, the front month options don’t have much time value. I figured I wanted to sell out of the money puts and calls (strangles) and hope that the price of GS after reporting earning remains within the range of my strikes and that they will expire worthless in the next 4 days.
At the time of purchase GS was trading at $65, a nice mid-strike price to work with. I sold 50 of the 85/45 strangles, giving me a wide $20 range (30% of the current price) for an income premium of $3,600. I also got a little riskier yet smaller by selling 10 of the 75/55 strangles for an additional $2,640 of collected premium. That position gives me a $10 range on both ends (15% of the current price). So basically, I’m betting GS won’t move more than 15% by Friday.
If stock price starts to reach the edge of the inside strangle (75/55) I will look to get out at my break-even points ($77.64 and $52.36) on this position but keeping my premium on the wider strangle. The break-evens on that strangle are $88.60 and $41.40.
I’m liking the options action during expiration week, esepcially the selling of options. Since there is not much time value left the premiums are not as juicy, but the probabilities of success (expiring worthless) are higher so these trades are more conservative in that regard.
Tuesday 12/16
GS closed the day yesterday up to $66-ish and this morning it’s up to $71 after the earnings announcement this morning. Of course, the puts are worth much less now, down about 70%-90%, yielding a nice gain so far. And the 85-strike calls I sold also came down in value due to a decrease in volatility, even though they are closer in-the-money now. The 75-strike calls I sold however are up, but not by much, only from 1.15 to 1.40. The decrease in volatility has helped to minimize their upside gain. It’s Tuesday and I’m thinking of just holding everything to expiration (this Friday) so they expire worthless. The only one that worries me is the 75-strike calls that I sold, though the stock would have to go up another $5 to start to reach my break-even point and I’m somewhat reassured in that these contracts expire in less than 4 days.


Tuesday, 12/23, after expiration
Well, I wish I had covered those $75 calls before expiration, GS went all the way over $80 by the end of the week and never came down. So those calls expired $5 ITM (in the money) and by Monday the calls were exercised and I found myself short 1,000 shares of GS! Luckliy though GS came down near $75 again today and I covered my short position for a small $300 loss. Not bad considering on Friday I was sitting on a $5,000 loss! So overall, I squeaked by with about a $5,000 one-week gain. I just felt GS was overpriced at $80 and I’m glad I held on enough at least to cover my short instead of covering on Friday and taking the $5,000 loss.
I think the takeaway for me was that when you’re selling volatility before an event, after the event happens and the volatility comes back down you need to take off the nearest-risk position (in this case, being short the $75 strike) and watch the rest of the positions closely until expiration. I would have been happier taking the loss on covering the $75 strike and sleeping more easily for the rest of the week. And I feel lucky GS eventually came back down to $75 after my calls were exercised. Because this was an event-driven play, once the event plays out you should take off some or all risk since it the position was based on a short-term thesis.
Even though the stock rose 8% shortly after I sold the calls, the fact that the calls only rose 21% is a testament of the power of volatility in pricing options.
