FAQs
Why does the CPI release move markets so dramatically?
CPI gauges consumer inflation, shaping expectations for Federal Reserve policy. A surprise reading can quickly alter rate projections, ripple through Treasury yields, and re-price risk assets within minutes.
What sectors are most sensitive to inflation surprises?
Rate-sensitive stocks such as banks, utilities, and real-estate investment trusts often react sharply. Tech and high-growth names may also swing because their valuations rely on lower discount rates.
Where can I stream the opening bell coverage?
Major outlets like CNBC and Bloomberg TV broadcast the NYSE and Nasdaq opening-bell ceremonies live each trading day.
How can I protect my portfolio during heightened volatility?
Consider diversifying across asset classes, using stop-loss orders, or hedging with options and volatility products. Maintaining adequate cash reserves also offers flexibility during turbulent sessions.
What time does extended-hours trading end?
After-hours trading on US exchanges generally runs until 8:00 p.m. ET, although liquidity tends to thin considerably after the regular close.
