Walgreens Boots Alliance Inc. (WBA)
I have passed a short iron fly spread on WBA, using options that trade for the last time nine days hence, on Jan. 12.
The bid/ask spread, at 29.9%, is too wide for my taste. I prefer single digits. Another problem lies with the long call leg; the strike closest to my goal of delta 10 has a delta of 20. The next highest jumps down to delta 3.
The profit zone for this position is between $78.50 to the upside and $74 to the downside.
WBA publishes earnings on Thursday after the closing bell.
Implied volatility stands at 28%, which is triple the VIX, a measure of the volatility of the S&P 500 index.
WBA’s IV stands in the 61st percentile of its annual range and the 74th percentile of its most recent broad movement.
The price used for analysis was $75.77.
The biggest immediate move after each of the past four earnings announcements was $2.07, and the average was $1.18. After eliminating the maximum and minimum post-earnings movements, the central tendency is $1.31.
The premium is 66.7% of the width of the position’s wings.
The risk/reward ratio is 0.5:1.
The zone of profit in the proposed trade covers a $3 move to the upside and a $1.50 move to the downside, showing heavy skewing.
Over the past four earnings announcements the price has closed the first post-earns session higher than the pre-earns close three times.
The break-even probabilities applied to the past four post-earnings moves show a 59.1% probability of the price rising while contained within the boundaries of the profit zone and a 16.0% probability of it falling while remaining profitable
Options analysis puts the expected move covering 85% of occurrences at $3.16, beyond the profit zone.
Decision for my account: No trade.
