Southwest Airlines transformation wins Wall Street as shares jump 44.5%

Southwest Airlines shares climbed 44.5 percent to $44.38 as assigned seating and new fees win over Wall Street. "The airline is getting on with the times," said a fund manager who has been adding to Southwest positions, as the carrier's business model overhaul draws institutional support. The transformation is showing up in the numbers. Q2 2026 revenue rose 16 percent to $8.43 billion, with net income up 9.4 percent to $233 million. EPS of $0.48 missed analyst estimates by 6.6 percent, while revenue fell 1.8 percent short of consensus. The 2026 EPS forecast was lifted 11 percent to $3.22, and the consensus price target rose to $52.36 from $48.25. The company guided Q2 RASM up 16.5 percent to 18.5 percent year-over-year, while FY 2025 passenger load factor came in at 77.4 percent, down from 80.4 percent a year earlier. The stock's 44.5 percent gain over the past year has outpaced the US Airlines industry's 29.3 percent return and the broader market's 16 percent. With a market cap of $22.7 billion and a forward P/E of 25.9x, the carrier trades at a premium to the industry average of 7x, reflecting investor confidence in the transformation's earnings potential. The overhaul includes assigned seating that began January 27, new fare bundles with premium options, checked bag fees, and a cloud migration with Amazon Web Services. The carrier also launched interline partnerships with Singapore Airlines and EVA Air, expanded to new destinations including St. Thomas, Knoxville, St. Maarten, and Anchorage, and introduced Getaways by Southwest vacation packages. JPMorgan is bullish on the carrier, citing above-consensus earnings estimates through 2026-2027 and expectations of outsized industry profit consolidation among stronger carriers. The bank's view contrasts with more cautious voices: a Seeking Alpha analyst rates LUV 'Hold' with a $44 price target, citing fuel price volatility and execution risks. Management's $4 per share 2026 EPS guidance appears optimistic to that analyst, whose revised estimate is $2.90. Fuel costs remain the key swing factor. Southwest chartered a ship this spring to move 12.6 million gallons of jet fuel from Houston through the Panama Canal to Los Angeles after securing a Jones Act waiver, highlighting the carrier's willingness to use atypical logistics to manage regional supply risk. The company has also ended its fuel hedging program, exposing earnings to crude price swings. The carrier's dividend of $0.18 per share quarterly yields 1.6 percent, with a payout ratio of 44 percent. However, the company is not cash flow positive, meaning the dividend may be funded from cash reserves or debt. Southwest's transformation comes as the airline industry consolidates. United Airlines Holdings, with a $40.2 billion market cap, and Delta Air Lines at $58.5 billion, have both outperformed the sector. Southwest's 73,456 employees serve 122 airports across the United States and internationally. The next catalyst is the Q3 2026 earnings report on October 22. Analysts expect the transformation's revenue initiatives to continue driving growth, with revenue forecast to grow 4.2 percent annually over the next three years, compared to 7.4 percent for the US Airlines industry. The stock's recent pullback of 6.9 percent over the past week suggests some investors are taking profits after the strong run, but the consensus price target of $52.36 implies roughly 18 percent upside from current levels.

Gaslog Shanghai hit in Hormuz as WTI tops $86 on Iran strikes

**Iran's renewed attacks on shipping in the Strait of Hormuz left a Qatari LNG carrier disabled and pushed WTI crude above $86 a barrel as Washington readied fresh strikes on Tehran.** The Bermuda-flagged LNG carrier Gaslog Shanghai was struck by an unknown projectile 11 nautical miles northeast of Oman on July 31 at 23:30 UTC while transiting outbound from the Gulf, according to maritime security firm Vanguard. The projectile hit the vessel's portside engine room, causing a fire that was extinguished, but the blast triggered a blackout and the carrier lost propulsion. UKMTO confirmed the regional coast guard had been informed and reported no injuries to the crew. Mohammad Bagher Zolghadr, secretary of Iran's Supreme National Security Council, warned that continued US maritime blockade would tighten Tehran's control over the Strait of Hormuz and could close other key maritime chokepoints. "This cost will be borne by the global economy, energy markets, and American voters," he said. WTI crude futures settled up more than 3 percent at $86 a barrel, while Brent rose over 1 percent to $90.12. Both benchmarks remain down more than 5 percent for the week, reflecting the whipsaw between ceasefire hopes and renewed escalation. The attack came hours after The Wall Street Journal reported that President Donald Trump had ordered the US military to prepare new strikes on Iran, potentially as early as this weekend. White House spokeswoman Karoline Leavitt said "Iran will continue to pay until it sits down at the negotiating table in a way that President Trump considers meaningful." The stakes for global energy markets are substantial. Roughly 20 percent of global LNG supply transits the Strait of Hormuz, and the waterway handles about 21 percent of global oil trade. A US strike on Iranian energy infrastructure — which CBS News reported Washington is considering, including oil refineries and power plants — could trigger Iranian retaliation that closes the strait entirely, a scenario that would send crude and LNG prices sharply higher. **A second Gaslog vessel hit in a week** The Gaslog Shanghai had its AIS turned off at the time of the attack. According to ship-tracking data from Pole Star Global, the carrier had crossed the Strait westbound on July 9 after the US-Iran memorandum of understanding broke down, and called at ports in Qatar and Kuwait before its eastbound transit on July 31. The vessel is the second Gaslog-owned LNG carrier hit in recent days — the Gaslog Salem was struck by a drone at berth in Egypt's Damietta port last week, at the same time as the FSRU Energos Winter on an adjacent berth. A separate incident on July 31 saw a Liberian-flagged tanker report a near miss with an unknown projectile 21 nautical miles northeast of Khasab, Oman. UKMTO said the master reported "a large splash and explosion in close proximity to the vessel," with no damage reported. Iran does not recognize the southern corridor in Omani waters where the US provides guided transits and has repeatedly threatened vessels using that route. **Conflict spreads beyond the Gulf** The attack on the Gaslog Shanghai marks the latest in a widening conflict. Over the past week, the US completed "large-scale" strikes on multiple Islamic Revolutionary Guard Corps targets, and Iran retaliated by attacking US military bases in Kuwait and Bahrain. Kuwait said its air defenses intercepted Iranian drone attacks, while Egypt reported a drone striking two vessels at Damietta port — the first attack on Egyptian territory since the war began, raising concerns that the Bab el-Mandeb strait at the Red Sea's southern end could become a second target. The last time the Strait of Hormuz faced a comparable threat was in 2019, when attacks on tankers off Fujairah and the downing of a US drone pushed Brent above $75 a barrel within weeks. The current escalation, with both sides actively striking military targets, carries a higher risk of miscalculation. If diplomatic talks show progress, Trump could still call off planned strikes, the WSJ reported — but with Iran's supreme national security council vowing to tighten control of the strait, the window for de-escalation is narrowing.

BYD July sales jump 21.8% as overseas deliveries hit record

BYD's global sales rose 21.8 percent in July to 419,211 new energy vehicles, the third straight month of year-on-year growth, as record overseas shipments of 179,841 units offset a still-soft domestic market. The pickup accelerated sharply from June's 5.46 percent gain, with July volume up 3.90 percent from the prior month to the highest level so far in 2026. "Vertical integration around the battery — especially battery cells — can have a positive impact on risk assessments, as this is based on a lot of their own data," Stefan Bratzel, founder and executive director of the Center of Automotive Management, said. BYD produces its own battery cells and key parts of the EV supply chain, giving it clearer visibility into battery performance over time than rivals that rely on third-party suppliers. Overseas shipments of passenger vehicles and pickups jumped 124.3 percent year on year to a record 179,841 units, accounting for about 43 percent of July's total. That left domestic sales at roughly 239,370 units, down about 9 percent year on year — a much narrower decline than in previous months. The core BYD Auto brand, spanning the Dynasty and Ocean lineups, sold 350,178 units, while off-road brand Fang Cheng Bao delivered 41,213, up 190.64 percent year on year and a monthly record. Denza sold 19,196 units, up 68.76 percent, and ultra-luxury Yangwang moved 485. The rebound comes as BYD works through production bottlenecks tied to its switch to a second-generation Blade Battery with flash-charging capability, which stretched delivery times for several key models. Sales of the Da Tang exceeded 10,000 units and the Tai 7 EV neared 10,000, though battery capacity still cannot keep up with demand. Cumulative NEV sales have now topped 17.3 million units. ## Overseas demand carries the year From January to July, BYD sold 2,227,722 NEVs, down 10.54 percent year on year — a narrowing from the 15.72 percent drop in the first half. Overseas sales of passenger vehicles and pickups totaled 969,208 units over the period, or 43.5 percent of cumulative volume. The export engine has become central to BYD's growth as it takes on Tesla and domestic rivals including Nio, Xpeng, Li Auto, Zeekr and Xiaomi in an increasingly crowded Chinese market. ## Battery bottleneck caps the upside BYD's second-generation Blade Battery, which uses LFP chemistry (lithium iron phosphate, cheaper but lower energy density than NMC), underpins the flash-charging models driving recent demand. Production capacity is rising but still cannot keep pace, the company said. For investors, the constraint cuts both ways: it signals demand strength but caps near-term volume growth. BYD, listed in Hong Kong as 1211, has leaned on its vertical integration — from cells to finished vehicles — to keep costs low even as a domestic price war pressures margins across the sector. The export-led recovery gives BYD a path to offset the domestic slowdown, but the durability of that growth depends on shipping capacity and overseas demand holding up. With overseas sales now approaching half of total volume, BYD's fortunes are increasingly tied to markets beyond China — a shift that will test whether its cost advantage travels as well as its cars.
