Berkshire's 'New King, New Atmosphere': Q1 Reduces Retail and Oil & Gas Holdings, Increases Google, and Also Establishes a Position in Airlines

Berkshire Hathaway's Q1 portfolio report, marking the start of the "Abel era" post-Buffett, revealed significant rebalancing. The firm made a major new investment, initiating a $2.65 billion position in Delta Air Lines—its first airline bet since 2020. It also aggressively increased its stake in Alphabet's A-class shares by over 200%, making it the seventh-largest holding. Conversely, Berkshire divested from several positions, completely exiting Amazon, Visa, Mastercard, and UnitedHealth. It also significantly reduced its stake in Chevron, selling approximately $8 billion worth of shares near their peak. The overall portfolio was streamlined, with the number of holdings dropping from 42 to 29, indicating a move toward a more concentrated and actively managed strategy under new leadership. Apple remains the top holding.

Mapping Volatility Through Time: Implied Volatility Heatmaps

Glassnode introduces two new implied volatility (IV) heatmap metrics—IV Moneyness Heatmap and IV Delta Heatmap—that visualize how options markets price risk across strikes and maturities over time, rather than at a single point. These tools help identify volatility regimes, such as periods of calm, stress, and transitions between them. The heatmaps display IV using color gradients, with red indicating high volatility and blue indicating low volatility. Key patterns include elevated put-side IV during drawdowns (signaling hedging demand), tail-risk repricing in deep out-of-the-money options, and regime shifts that inform trading strategies like hedging in low-vol environments or selling premium in high-vol periods. Available in Glassnode Studio, these metrics provide a dynamic view of market expectations and risk sentiment.
