BB Analysis

BlackBerry Ltd. (BB)

BB publishes earnings on Wednesday before the opening bell.

I shall use options that trade for the last time 10 days hence, on Dec. 29.

Implied volatility stands at 55%, which is 5.5 times the VIX, a measure of the volatility of the S&P 500 index.

BB’s IV stands in the 73rd percentile of its annual range and the 88th percentile of its most recent broad movement.

The price used for analysis was $10.91. With no expectation of an earnings surprise and no strong trend, I shall use a direction-neutral iron fly construction.

Premium: $0.80 Expire OTM
BB-iron fly Strike Odds Delta
Long 12.50 87.2% 16
Break-even 11.80 70.0% 34
Short 11.00 56.2% 49
Short 11.00 44.1% 51
Break-even 10.30 59.0% 36
Long 9.50 83.6% 13

The premium is 0.80% of the width of the position’s wings.

The risk/reward ratio is 0.9:1.

The zone of profit in the proposed trade covers a $0.80 move to the upside and a $0.70 move to the downside. The biggest immediate move after each of the past four earnings announcements was $3.31, and the average was $1.24. After eliminating the maximum and minimum post-earnings movements, the central tendency is $0.73.

The expected move covering 85% of occurrences is $0.89, beyond the profit zones in either direction.

The bid/ask spread is 11.8%.

Decision for My Account

So much to dislike about BB’s analysis. The average move and the expected move are wider than the profit zone in either direction, and the bid/ask spread is wider than I like — I prefer single digits, the spread here is nearly 12%.

I’m passing on the trade.
