Compare. Contextualize. Stress-test.
BlockViz unifies indexed comparisons, dominance and treemap views, portfolio intelligence, and scenario simulators into one focused workspace.
No credit card required.
Problem
Traders and research teams need clean relative context, not endless dashboards. Without structured comparisons and scenario tools, it is easy to miss leadership shifts, concentration risk, and decision impact.
Common symptoms
Single charts don’t reveal leadership, rotation, or breadth.
Dominance, composition, and concentration live in separate views.
Spreadsheet workflows slow iteration and reduce decision quality.
Solution
Compare relative performance, map structure and concentration, then stress-test changes before sizing decisions.
What you get
Step 1 - Compare
Indexed comparison, best and worst days, and seasonality expose relative strength.
Step 2 - Map Structure
Dominance, treemap, and market cap development show composition and share drift.
Step 4 - Allocate
Portfolio tracking and comparison reveal what drives risk and return.
