Why Use Vunelix Stock Heatmap
Professional traders and fund managers use heatmaps because pattern recognition beats number crunching. When the entire Technology sector glows green while Financials turn red, you don't need to check 500 individual stocks to understand the market narrative. Vunelix's stock heatmap gives you that institutional-grade market overview.
The treemap visualization excels at revealing market breadth and sector leadership. Is the S&P 500 up because of broad participation or just a few mega-caps? Are small caps confirming the rally? Which sectors are rotating in or out? These questions get answered visually, not through spreadsheet analysis. Perfect for pre-market prep, intraday monitoring, or end-of-day review.
Frequently Asked Questions
Block size corresponds to market capitalization. Apple, Microsoft, NVIDIA, and Amazon appear largest because they're trillion-dollar companies. This weighting shows you which stocks actually move the index - mega-caps have outsized influence on S&P 500 performance.
Vunelix offers S&P 500 (large-cap benchmark), NASDAQ 100 (tech-heavy), Dow Jones Industrial Average (30 blue chips), and All US Stocks for comprehensive market coverage. Each index has its own dedicated view.
Stocks are grouped by sector within the heatmap. When an entire sector block turns uniformly green or red, that's sector-wide movement. Mixed colors within a sector suggest stock-specific news rather than sector rotation.
