Rising bond yields yanked the Nasdaq lower as semiconductor stocks tumbled in a market-wide rotation out of rate-sensitive tech names.
What happened
The Nasdaq fell sharply while chip stocks cratered, erasing roughly 500 billion dollars of market value. Rising bond yields compressed richly valued growth equity valuations and triggered a rush out of tech.
Why it matters
Higher yields make the distant earnings of growth companies worth less in today’s money, hitting chipmakers and the Nasdaq hardest. The sell-off is a risk-off rotation: money leaving tech means cheaper borrowing and expansion plans get repriced for a whole sector.
The case against
The market’s trend still reads constructive, meaning this could be a pullback within an uptrend rather than the start of a sustained fall. Prices are slipping but the mood has not turned into outright fear, and market stress remains calm.
What settles it
Whether bond yields continue climbing enough to break the constructive uptrend in chip and Nasdaq names.
