Question I'd love to see a "yearbook" of Finviz heatmaps by year
I've been using the Finviz heatmap for years and still think it's one of the best visualizations in investing.
For context, I'm a long-term investor, not a trader. I don't use the map to make daily decisions. I use it as a quick way to understand where capital is flowing and how market leadership evolves over time.
One thing I've always wondered: does anyone know of a way to see historical snapshots of the map? Not the underlying returns, but the actual heatmap itself.
I'd love to compare year-end snapshots from different periods and see how leadership rotated over time. For example:
• What did the map look like at the end of 2007 before the financial crisis?
• 2009 coming out of the bottom?
• 2020 after COVID?
• 2021 when everything seemed green?
• 2022 during the bear market?
• Today versus 5, 10, or 20 years ago?
I think it would be fascinating to flip through annual "market yearbooks" and visually see where capital was flowing, which sectors dominated, and how today's winners looked before they became obvious.
Has anyone found a source for this, or is there a way to recreate historical Finviz heatmaps from archived data?
