Company evidence
Start with earnings, guidance, data-centre demand, customer spending, gross margin, operating expense, product execution, and supply. A chart move can reflect a change in expectations rather than a change in the latest reported quarter.
Price and volume
Mark the higher-timeframe trend or range, important gaps, prior breakout zones, volume response, and regular-session acceptance. A brief pre-market move is not the same as sustained liquidity.
Sector and index context
Compare NVDA with the semiconductor group, Nasdaq, major customers, and broad risk appetite. Relative strength can support a thesis; sector-wide weakness can undermine an isolated chart pattern.
Catalyst and invalidation
Earnings, product events, export controls, analyst revisions, and rates can alter the evidence quickly. Every scenario needs a condition that would make it wrong.
