Marketgenius is a free, mobile-first stock market visualization platform. The centerpiece is a stock heatmap where tile sizes reflect the metric being viewed, not a fixed market-cap weighting. Switch from percent change to dividend yield to PEG and the same universe re-sizes around the new signal.
A portfolio view shows what someone owns. A metric view shows where a signal lives. Combining them shows whether a signal is concentrated in places disciplined investors have already moved into.
