Quoted in index points, often to one or two decimals.
Commonly $1 per point per contract on CFDs, with mini variants; broker specification decides.
Near-24h weekday CFD trading with a daily break (broker-dependent); underlying US cash session 13:30–20:00 UTC.
US cash hours dominate; the open and the last hour ('power hour', 19:00–20:00 UTC) are the two liveliest stretches.
US100 tracks the Nasdaq 100 — the largest non-financial US companies, dominated by mega-cap technology. That concentration makes it the highest-beta of the major indices: when markets move, US100 usually moves furthest, in both directions.
It is the index most sensitive to interest-rate expectations, because long-duration tech valuations reprice hardest when yields shift. CPI releases and Fed days are effectively its scheduled earthquakes.
How US100 behaves
- Consistently out-ranges US500 and US30 in percentage terms.
- A handful of mega-cap earnings reports (after-hours) can gap the entire index.
- Trends hard in momentum regimes — and reverses hard when the regime breaks.
Risk notes for US100
- Stops must be sized from US100's own range, which can be several times US30's percentage move on the same news.
- After-hours earnings gap risk is concentrated: a few companies are a large share of the index.
- Holding US100 and US500 together is largely one bet — the overlap in constituents is heavy.
Whatever the instrument, the sizing method is the same: place the stop where the trade idea is invalid, then size the position so that stop costs a fixed fraction of the account. Our position size calculator does that math, and the stop-loss and risk–reward guide explains why the order of operations matters.
US100 — frequently asked questions
Why is US100 more volatile than other indices?
Concentration and duration: a few rate-sensitive technology mega-caps dominate its weighting, so both their earnings and every shift in yield expectations move the index hard. It routinely covers the biggest percentage range of the major US indices.
When is the best time to trade US100?
US cash hours, 13:30–20:00 UTC — particularly the first hour after the open and the final hour of the session. Overnight CFD prices move on thin books and often retrace at the open.
How much is a US100 point worth?
Commonly $1 per point per CFD contract, with smaller minis available; conventions differ by broker, so read the specification and let any automated system pull it from broker data.
Reference information, not financial advice. Contract sizes, pip values, hours, and spreads vary by broker — your broker's specification is authoritative, and RezSync Algo always reads these values live from the broker rather than assuming them. Trading involves substantial risk of loss; forward-test on a demo account before any live decision.
