TSMC, Samsung Fail to Lift Chip Stocks

Instead, TSMC shares fell in Taiwan and Samsung stock slipped in Seoul, while U.S. semiconductor names came under pressure in early trading. The move is important for investors because it suggests the market is no longer reflexively rewarding strong AI-linked fundamentals when rates and energy prices are moving in the other direction.

The shift comes as the 10-year Treasury note auction cleared with solid demand — a 2.77 bid-to-cover and a 5.300% high yield versus 5.317% when-issued — yet bonds still failed to rally meaningfully. The 10-year yield was last around 5.22%, while the 2-year/10-year curve sat at 44 basis points, underscoring a bond market that remains far less forgiving than equities had hoped.

Oil is adding to that pressure. Crude is rising on reports the U.S. could attack Iran before the midterm elections, renewed Iranian attacks on tankers and Houthi violence in the region, keeping geopolitical risk and inflation risk intertwined. That combination is especially awkward for equities because higher oil can keep Treasury yields elevated and compress valuation multiples for growth stocks.

The early read-through is a rotation test for the market’s biggest winners. Money flows in Amazon, Microsoft, Nvidia and Tesla were negative, while Apple, Meta and Alphabet were neutral, suggesting the Magnificent Seven is no longer moving as a single high-beta block.

Adalytica’s SPY gauge showed extreme greed at 90 even as awareness remained in fear territory, another sign of a stretched market facing a potential character change. For investors, the next checkpoints are the 30-year Treasury auction, the path of 10-year yields and whether crude keeps climbing; if so, the market may continue to favor defensive positioning over the AI winners that have led for months.
