1. Oil Prices Surge 35% in Biggest Weekly Gain Ever

West Texas Intermediate crude shattered records this week, breaking above $90 per barrel and posting a staggering 35% weekly gain—the largest since oil futures trading began in 1983. The surge came as Iran's actions threatened the Strait of Hormuz, a critical chokepoint for roughly one-fifth of global oil supplies. Energy stocks became the only refuge in an otherwise brutal market, with companies like Exxon Mobil, Chevron, and Occidental Petroleum climbing as investors rotated into the sector.

2. Greg Abel Invests Entire Salary in Berkshire Stock

In a powerful display of alignment with shareholders, Berkshire Hathaway's new CEO Greg Abel announced he will use his full $15 million after-tax salary to purchase company shares annually. The move came just two months into his tenure following Warren Buffett's retirement, sending a clear message about his confidence in the conglomerate's future. Abel already bought approximately $15.3 million worth of Berkshire shares this week, with plans to continue these purchases after each annual results release for as long as he leads the company.

3. Berkshire Resumes Share Buybacks Under New Leadership

Berkshire Hathaway confirmed it has restarted its share repurchase program after pausing during the leadership transition from Buffett to Abel. With a cash pile exceeding $325 billion, the company has significant flexibility for capital deployment. Abel indicated buybacks will continue as long as shares trade below the company's intrinsic value estimates, providing a floor for the stock price during uncertain times while reducing outstanding shares.

4. Defense and Energy Stocks Lead as Tech Sells Off

Geopolitical tensions and AI disruption fears created a dramatic sector rotation this week. Palantir surged on its defense and AI positioning, while Northrop Grumman jumped 6% as military spending expectations strengthened. Energy producers outperformed across the board. Meanwhile, software stocks collapsed—the iShares Tech-Software ETF has plunged more than 29% from its recent high as investors fear AI will disrupt the software-as-a-service business model that dominated the last decade.

5. Tesla Bull Investor Buys 1 Million Nvidia Shares

Billionaire KoGuan Leo, one of Tesla's largest individual shareholders with a net worth of approximately $12.8 billion, made waves by announcing he purchased 1 million Nvidia shares. In a tweet, he declared: "I am convinced AI is NOT a bubble, it is only the beginning." The move represents a strategic diversification from his concentrated Tesla position while doubling down on his conviction that artificial intelligence represents a generational investment opportunity.
