TradingKey - As high mortgage rates continue to weigh on the U.S. housing market and put pressure on homebuilder earnings, Berkshire Hathaway (BRK.A), long built by Warren Buffett, has further expanded its investment in the U.S. residential construction sector.

On September 16, Broadcom (AVGO) hit a recent intraday low of $335.80, pulling back 32% from its all-time high of $494.20 and almost entirely erasing its year-to-date gains. Yet just a few months ago, Broadcom was hailed by the market as the most certain winner in AI computing power; now, it has become a poster child for unfulfilled expectations. The root of this shift traces back to its Q2 FY2026 financial report released on June 3. While AI semiconductor revenue reached $10.8 billion—up 143% year-over-year—and Q3 guidance projected over 200% year-over-year growth, management merely reiterated its target of "exceeding $100 billion in AI chip revenue by FY2027" as unchanged, declining to raise it. Market expectations, already priced at a P/E ratio of around 90x, lost the fuel to expand further, sending the stock price into a continuous decline. As the share price dropped, its valuation also underwent a reset. Could this now mark a turning point for the stock?

On September 24, Eastern Time, Meta Platforms (META) reached an intraday price of $777.89, hitting a nearly one-year high. Following the Meta Connect event, JPMorgan raised its price target on the company from $820 to $920 while maintaining an Overweight rating. The core reason is that the monetization path for Muse is becoming increasingly clear, leaving the bank more optimistic about Meta's growth potential beyond advertising.

U.S. stock indexes surged in the short term while crude oil prices fell, reflecting market expectations of a de-escalation in tensions. According to Reuters, negotiators from the U.S. and Iran are in New York exploring a phased path to end the war, with key proposals including Iran reopening the Strait of Hormuz and the U.S. lifting its economic blockade against Iran.
