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.
Moreover, 24 analysts surveyed by Yahoo! Finance have an average price target of $58.69. That is +16.7% higher than today. Similarly, Barchart's mean survey price is $61.09, or +21.5% higher.
And AnaChart.com, which tracks recent analyst recommendations, shows that 16 analysts have an average price of $65.55. That is over 30% over today's price.
The bottom line here is that from a historical forward P/E multiple standpoint and using analysts' target prices, DAL stock looks cheap.
That could explain why investors are both buying out-of-the-money calls three weeks away in expiration and selling covered calls.

A significant update could arrive soon. The Times of India reportedTuesday that a preliminary report had been submitted to officials, citing “top sources.” Details of the report weren’t available. Boeing didn’t respond to a request for comment about the report.
Vertical Research Partners analyst Rob Stallard noted in a Wednesday report that investigations focused on engine fuel switches, adding it didn’t appear to be a design issue. No fuel to the engines, for whatever reason, would cause a loss of power.

Reports from the Economic Times of India noted that investigators are looking into a new angle: whether or not fuel control switches in the aircraft had been moved ahead of the aircraft’s crash. The move may have been accidental, or it may have been deliberate. But the reports noted that “…the position and movement of the engine fuel switches…” is of particular interest right now, based on a combination of factors. This combination includes flight data, voice recordings, and a set of simulations that Boeing itself conducted to aid the investigation.
A preliminary report is expected by Friday, the report noted, but one report from aviation safety expert John Cox said that an “accidental movement” would be rather difficult to pull off. The controls are apparently protected against most accidents, and are not sufficiently sensitive to move with mere jostling. But shutting off one of these switches would cause what the report called “…an almost immediate loss of power.” This again meshes well with earlier reports about the aircraft’s Ram Air Turbine (RAT) deploying.

Investing.com -- Super Micro Computer (NASDAQ:SMCI) is facing mounting headwinds in the AI server space, according to Bank of America (NYSE:BAC) Securities, which resumed coverage of the stock with an Underperform rating and a $35 price objective, implying roughly 29% downside from current levels.
While revenue growth remains strong, BofA warns that “margins will remain under pressure in a more competitive AI server/rack market.”
The company’s gross margins have already dropped sharply, from 18% in fiscal 2023 (FY23) to 13.9% in FY24 to 11.3% FY25, with BofA forecasting further declines to 9.4% by FY27.
Moreover, component availability, including GPUs and liquid cooling parts, may limit future growth and negatively impact SMCI’s ability to ship its backlog, the bank cautions.
BofA also highlights increasing competition from Dell (NYSE:DELL) and Hewlett Packard Enterprise Co (NYSE:HPE), which are gaining traction with enterprise customers and large-scale AI workloads.
Dell, for instance, has become a supplier to CoreWeave and xAI, both previously associated with SMCI. Dell’s AI server backlog reached $14.4 billion as of May, and the firm expects to ship more than $15 billion in fiscal 2026.
“Dell is seeing strong revenue growth from AI servers and racks and we model Dell reaching AI server market share similar to Super Micro in 2025, and our forecast suggests that Dell can gain higher market share vs Super Micro in future years,” analysts led by Ruplu Bhattacharya noted.
Additionally, BofA believes that liquid cooling—once a competitive edge for SMCI—could be commoditized as other vendors scale their own solutions. “For large projects, vendors may need to offer this [for] free as an incentive to win,” analysts warned.
Litigation, shareholder dilution, and financial reporting issues add further risk. SMCI is working to resolve material weaknesses in its internal controls, and is under investigation by the U.S. Department of Justice and SEC following a short seller report.
On top of this, the company may need to raise capital to fund working capital, which could dilute existing shareholders.
“We think SMCI should trade at a discount to peers,” analysts said, noting their price target is based on a 13x multiple of 2026 EPS, above the stock’s long-term median. Despite a strong growth profile, the analysts characterize SMCI as a “show-me story.”
Possible upside risks that could boost the stock include unexpected market share gains from enterprise and sovereign customers, successful competition on new GPU platforms, and potential gross margin improvement from increased adoption of higher-margin services, BofA said.
