MarketsMorning Brief: TSM Confirms Supercycle, but 'Warsh Premium' Spikes Yields
Taiwan Semiconductor ([[TSM]]) confirmed the AI supercycle with a massive $52-56B capex commitment, yet the S&P 500 finished the week flat as the "Warsh Premium" drove 10-Year yields to a 4-month high of 4.23%. While TSM consolidated Friday, the hardware complex ignored the rate spike—Micron ([[MU]]) surged 7.8% and Super Micro ([[SMCI]]) jumped 10.9%—validating the infrastructure buildout thesis. The variant view: The Russell 2000 hitting a record high despite rising yields signals that "animal spirits" and M&A hopes are currently overpowering cost-of-capital headwinds, a divergence that typically resolves violently. A key confirmation signal emerged in Micron, where an insider purchased $8 million in stock near all-time highs. Watch the 4.30% yield level next week; a breach likely triggers algorithmic selling in risk-parity funds, threatening the rotation trade.
