JBL Analysis

Jabil Inc. (JBL)

Update 12/15/2017: JBL’s earnings of $0.80 per share came in 1.6% below the Street estimate of $0.81. Shares rose a dollar in after-hours trading after the announcement, stayed high overnight, and then a dollar in the 10 minutes before the opening bell and the first 10 minutes of the session. I exited soon after the open at 31.5% of maximum potential profit.

Shares rose by 1.7% during my holding period of less than a day, or a +637% annual rate. the options position produced a 46% return for a +16,790% annual rate.

Going into the trade Zacks gave JBL a neutral rank (3) with no expectation of an earnings surprise. The average directional index (ADX) stood at 17.4, with a directional index gap (+DI minus -DI) of -7.48, a bearish reversal. The ADX stood in the 45th percentile of its most recent broad movement.

JBL rose $0.42 from the pre-earns close to the end of the trading the first session after the announcement, stay well within the $1.54 average movement of the past four announcements, the central tendency of $1.24 and the maximum of $2.58.

The expected move of $1.55 contained JBL’s maximum rise of $1.13, which also stayed within the upside profit zone, $1.46.

JBL publishes earnings on Thursday after the closing bell.

I shall use options that trade for the last time eight days hence, on Dec. 22.

Implied volatility stands at 36%, which is 3.5 times the VIX, a measure of the volatility of the S&P 500 index.

JBL’s IV stands in the 78th percentile of its annual range and the 82nd percentile of its most recent broad movement.

The price used for analysis was $27.50.

I shall use a direction-neutral iron fly structure for the position.

Premium: $1.46 Expire OTM
JBL-iron fly Strike Odds Delta
Long 30.00 85.4% 17
Break-even 28.96 75.0% 28
Short 27.50 51.5% 52
Short 27.50 48.3% 48
Break-even 26.46 64.0% 32
Long 25.00 84.5% 13

The premium is 58.4% of the width of the position’s wings.

The risk/reward ratio is 0.7:1.

The zone of profit in the proposed trade covers a $1.46 move to the upside and $1.04 to the downside. The biggest immediate move after each of the past four earnings announcements was $2.58, and the average was $1.54. After eliminating the maximum and minimum post-earnings movements, the central tendency is $1.24.

The expected move covering 85% of occurrences is $1.55, 9 cents beyond the profit zone to the upside and 51 cents to the downside.

The bid/ask spread is 17.2%.

Decision for My Account

I have entered a position on JBL as described above. The stock at the time of entry was priced at $27.51.

I may regret it. The bid/ask spread is too wide and the profit-zone coverage, especially to the downside, is less than I would like. Nonetheless, I have jumped in, perhaps because the lack of decent options trades over the past few weeks has left me willing to bend my standards a bit.
