Stock Market Movers

Markets move every day — the question is which names moved, why, and whether the option market saw it coming. Optionistics' stock-market-movers screener answers all three.

Each session we surface:

• Top gainers and losers by daily percentage change.
• Unusual option volume — names trading more contracts than their 90-day average.
• Implied volatility spikes — where the option market is pricing in a bigger move than yesterday.

Pair these with the Hot Sheet and the Volatile Stocks screener for a full top-of-market dashboard.
