Costco (COST)

Costco (COST) is due to announce earnings Thursday after the closing bell.

The stock is currently trading for 483.06.

  • IV Rank: 23.5
  • IV: 29.3%

Expected Move for the June 2, 2023, Expiration Cycle: 465 to 502.5

Knowing the expected range, I want to place the short call strike and short put strike of my iron condor outside of the expected range, in this case outside of 465 to 502.5.

If we look at the call side of COST for the June 2, 2023, expiration, we can see that selling the 515 call strike offers an 87.65% probability of success. The 515 call strike sits just above the expected move, or 502.5.


Now let us move to the put side. Same process as the call side. But now we want to find a suitable strike below the low side of our expected move, or 465. The 450 put, with an 87.54% probability of success, works.


We can create a trade with a nice probability of success if COST stays within the 65-point range, or between the 515 call strike and the 450 put strike. Our probability of success on the trade is 87.65% on the upside and 87.54% on the downside.

Moreover, we have a 6.6% cushion to the upside and a 6.8% margin of error to the downside.

If one wanted to make a trade, below are the potential strikes that make the most sense or are at least a starting point for a trade.

Here is the trade:


Sell to open COST June 2, 2023, 515 calls

Buy to open COST June 2, 2023, 520 calls

Sell to open COST June 2, 2023, 450 puts

Buy to open COST June 2, 2023, 445 puts for roughly $0.72 or $72 per iron condor.

Our margin requirement would be roughly $428 per iron condor. Again, the goal of selling the COST iron condor is to have the underlying stock stay below the 515 call strike and above the 450 put strike immediately after COST earnings are announced.

Here are the parameters for this trade:

  • The probability of success – 87.65% (call side) and 87.54% (put side)
  • The maximum return on the trade is the credit of $0.72, or $72 per iron condor
  • Max return: 16.8% (based on $428 margin per iron condor)
  • Break-even level: 515.72 – 449.28.
