The model's market view
US market on Oct 22 2026 is choppy and earnings-driven: Nasdaq under pressure from chip and mega-cap tech weakness while defensive and earnings-beat names lead gainers. Top movers list is dominated by small-cap biotech spikes but several large-cap names with substantive catalysts meet the price >= $5, market cap >= $1B and 20-day average dollar volume >= $20M filters, allowing a clean set of both continuation and reversal setups into Oct 23.
