COST Analysis

Update 6/4/2015: As expiration approached, COST was moving swiftly toward the lower boundary of the profit zone. I exited my position in order to preserve my gains.

Shares declined  by 2.6% over seven days, or a -136.8% annual rate. The options position produced a 56.4% yield on debit, for a +2,941% annual rate.

The big-box discount chain Costco Wholesale Corp. (COST), headquartered in Issaquah, Washington, publishes earnings on Wednesday after the closing bell.

I shall use the JUN1 Weeklys series of options, which trades for the last time nine days hence, on June 5.

The Trade

I've skewed the zone of profitability somewhat to the downside in order to account for the general bearish tone of the market, leaving $138 at the top of the one standard deviation range unprofitable. Moreover, 43 cents of the downside is also beyond the profit zone.

It's not an optimal position. However, I ought to get a bump from the collapse in volatility after the earnings announcement, and volatility itself, while high relative to its own past, is in absolute terms somewhat on the low side, which ought to help the chance that the price will stay within the profit zone.

The risk/reward ratio stands at 1.4:1. The premium is $0.78 ($0.50 for the calls and $0.28 for the puts), with the stock at $144.42.

Decision for My Account

I've opened a position as described above.
