- Seek concrete timelines and infrastructure plans before pricing long-term AI infrastructure exposure.

- Berkshire Hathaway bought Occidental's petrochemical unit for $9.7 billion, leveraging its existing stake.
- The deal gives Occidental liquidity to buy back shares while Berkshire gains a business it already understood well.

- Markets historically shrug off government shutdowns, with average 12-month S&P returns ~12% after a shutdown.
- Shutdowns often delay economic data, increasing short-term volatility but rarely changing long-term trends.
