Our IC on ABT lost money this week as ABT stock increased in value. The table below shows the current status (ignore the -15 ABT 02/19/2021 $127 Calls as they are part of a covered call).
The “wings” of our IC include a call spread of $125/$135 (10 point spread) on the upper side and put spread $110/$120 (10 point spread) on the lower side. When we established the IC we received $13,255 in premium for selling the two spreads.
Max Profit = Premium Received.
Max Loss = Spread between the wings (10) * #contracts (30) * 100 shares per contract – Premium Received = $16,745.
Current stock price of $128.23 is above the lower strike on our call spread.

To realize max profit we need ABT to be between $120 and $125. When we set up the IC it seemed like a reasonable assumption. In hindsight I should have used a wider range. A wider range would have reduced the premium received (Max Profit) but increased the probability of the stock remaining inside the range. Position is currently losing $1,225.
The position has a lot of time left (expires March 19) and ABT may drop back. If the price goes above $135 we will incur the maximum loss. We do have an option of rolling up the Put from $120 to $125 which would generate additional premium and reduce the maximum loss.
Yesterday I established a new IC on DXCM following the earnings announcement. Took the lesson learned about wider range. The options in the table below with the quantity 20 and -20 make up the IC. The spread between the put spread ($360) and call spread ($460) is much wider than what we did on ABT IC. The stock has a $100 range to move and allow us to make maximum profit. Our Max profit is the sum of the premiums received ($15,680). Max Loss is the spread of the wings (20) x number of contracts (20) x 100 shares per contract – Premium Received = $24,320. Current profit is $1,340…….
