Energy traders are closely monitoring any signs of supply disruption, though no immediate changes to shipping or production have been reported.
Berkshire’s airline investment is drawing particular attention because of Buffett’s historical wariness of the sector. “This could simply be a value play on depressed valuations, but it also might reflect a more bullish view on travel demand than the market currently prices in,” said a portfolio manager who tracks Berkshire filings. The trade is likely to increase speculation about Buffett’s broader market outlook.
On Lululemon, the proxy battle introduces near-term uncertainty for shareholders. The activist’s proposals may gain traction if the company’s recent quarterly results, expected in the coming weeks, show continued margin pressure.
