CVS Health Corp. (CVS)
CVS publishes earnings on Monday before the opening bell.
I shall use options that trade for the last time 14 days hence, on Nov. 17.
Implied volatility stands at 38%, which is 4.1 times the VIX, a measure of the volatility of the S&P 500 index.
CVS’s IV stands in the 88th percentile of its annual range and the 87th percentile of its most recent broad movement.
The price used for analysis was $69.53.
The premium is 47.6% of the width of the position’s wings.
The risk/reward ratio is 1.1:1.
The zone of profit in the proposed trade covers a $3 move either way. The biggest immediate move after each of the past four earnings announcements was $9.86, and the average was $3.35. After eliminating the maximum and minimum post-earnings movements, the central tendency is $1.64.
The expected move covering 85% of occurrences is $3.60, beyond the profit zone.
The bid/ask spread is 13.6%.
Decision for My Account
As originally constructed, with the long wings at the 10 delta mark ($77 and $63), the risk/reward ratio was overly high, at 1.3:1. I narrowed the wings by a dollar on either side, getting an acceptable risk/reward ratio but at the cost of widening the bid/ask spread and narrowing the profit zone.
Either way, the result fails to meet my standards, and I am passing on CVS today.
