Barchart’s Unusual Stock Options Activity Report shows that a large volume of out-of-the-money (OTM) Delta Air Lines (DAL) call options have traded. That is a bullish signal from investors ahead of its earnings release tomorrow morning.

DAL is at $50.29 in midday trading on July 9, well off its peak of $69.06 on Feb. 5. However, it’s still up from the April 8 low of $35.88. It could have much further to go using its historical valuation parameters.

Analysts expect to see lower Q2 revenue and slightly lower operating margins compared to last year. For example, Seeking Alpha states that the consensus is for $16.21 billion in revenue vs. last year’s $16.658 billion in sales.

Moreover, last year Delta produced an operating margin of 14.7%, (i.e., operating income/revenue). That is lower than this management’s guidance for the upcoming Q2. Last quarter, Delta said it expects an operating margin of between 11% to 14% for Q2.

This lower profitability outlook is already discounted in DAL stock. So, if its margins come in better than expected, DAL could have potential upside (and vice versa).

That could be why there is heavy trading volume in Delta call options today.

This can be seen in today’s Barchart Unusual Stock Options Activity Report. It shows that over 5,100 call options have traded at the $55.00 strike price, over 9% above today’s price for calls expiring in 23 days on Aug. 1.

This means that buyers of these calls expect to see DAL rise to $56.96 or higher (i.e., including the premium they paid), or +12.7% from today. They have slightly over 3 weeks for this to happen.

Moreover, it’s also moderately bullish from a seller of these calls standpoint. They have received at least a 90-cent premium or a 1.78% yield on today’s price (i.e., $0.90/$50.50 = 0.0178).

In other words, they are willing to sell their shares at $55.90 (i.e., selling covered calls at this out-of-the-money strike price). That could provide a +10.7% (including the premium received) gain for a 3-week obligation to sell at the $55.00 strike price.

And no wonder, as DAL stock could be undervalued from a statistical standpoint.
