Greg Abel Made Major Additions to Alphabet and Delta Last Quarter While Berkshire Bought Back $4.4 Billion of Its Own Stock. Is This a Buying Signal Investors Should Watch?

Under new CEO Greg Abel, Berkshire Hathaway significantly increased its positions in Alphabet and Delta Air Lines during Q2 2026, while also repurchasing $4.5 billion of its own stock. Abel appears to be following Warren Buffett's value-investing philosophy but with more aggressive capital deployment.

Prediction: UPS Will Miss Estimates (but the Stock Could Still Be a Good Value)

UPS faces headwinds from elevated fuel costs, Amazon's new supply chain services, and declining e-commerce demand, which could lead to missed earnings estimates in Q3 2026. However, the stock's high dividend yield and market expectations of a miss may position it for recovery if the company merely meets expectations. The dividend sustainability remains a concern despite the potential value opportunity.

Archer Aviation vs. Joby Aviation: Which EV Airplane Stock Is a Better Buy in 2026?

Both Archer Aviation and Joby Aviation are developing electric vertical takeoff and landing (eVTOL) aircraft for commercial use, but face significant financial challenges with massive operating losses and negative cash flows. Joby is recommended as the better buy due to its lower valuation multiple (46x P/S vs. 546x), early revenue generation from its Blade acquisition, and more advanced manufacturing capabilities, though both remain highly speculative investments with substantial regulatory and execution risks.

Joby and Archer Each Burn Roughly $200 Million a Quarter. Here's Which One Runs Out of Cash First

Joby Aviation and Archer Aviation are both burning through approximately $200 million per quarter as they develop eVTOL technology. Joby has $2.2 billion in cash reserves and could sustain operations for roughly two years at current burn rates, while Archer has $1.5 billion and could last just over a year. Both companies are making technological progress and have partnerships with major aviation companies, which should help them raise additional capital before running out of cash.

1 eVTOL Stock to Buy, and 1 to Avoid

Joby Aviation is recommended as a superior eVTOL investment compared to Archer Aviation. Joby's S4 aircraft offers better range (150 vs 100 miles) and speed (200 vs 150 mph), uses more efficient single-tilt-rotor technology, and operates a vertically integrated business model with stronger FAA certification progress. Despite trading at a higher valuation multiple (15.5x vs 8.5x 2028 sales), Joby's superior technology and operational model justify the premium over Archer's OEM-focused approach.

Prediction: Here's What a $5,000 Investment in Joby Aviation Will Be Worth in 3 Years

Joby Aviation, an eVTOL aircraft developer, has underperformed since going public but could see significant growth once the FAA certifies its commercial flights. The company's S4 aircraft offers advantages over competitors like Archer Aviation, with backing from Toyota, Delta Air Lines, and Uber. Analysts project revenue could grow from $53M in 2025 to $435M by 2028, potentially doubling the company's market cap to $14B over three years, though the stock remains highly speculative with ongoing cash burn and shareholder dilution.
