Last week, in one of our Terry’s Tips portfolios, we placed calendar spreads with strikes about $5 above and below the stock price of ULTA which announced earnings after the close on Thursday. We closed out our spreads on Friday and celebrated a gain of 86% after commissions for the 4-day investment. It was a happy day.
This week, this portfolio will be making a similar investment in Broadcom (AVGO) which announces earnings on Thursday, December 8. I would like to tell you a little about these spreads and also answer the question of whether calendar or diagonal spreads might be better investments.
Comparing Calendar and Diagonal Spreads in an Earnings Play
Using last Friday’s closing option prices, below are the risk profile graphs for Broadcom (AVGO) for options that will expire Friday, December 9, the day after earnings are announced. Implied volatility for the 9Dec16 series is 68 compared to 35 for the 13Jan17 series (we selected the 13Jan17 series because IV was 3 less than it was for the 20Jan17 series). The graphs assume that IV for the 13Jan17 series will fall from 35 to 30 after the announcement. We believe that this is a reasonable expectation.
