Distinguish broad participation measures from one index’s movement.

Open Market Breadth Dashboard (opens in a new tab)
Compare one displayed US or global heatmap with an index observation. Record the date, market universe and color definition; the dashboard does not calculate an advance-decline line.
Keep this course tab open. Return here to answer the questions and continue to the next lesson.
Check your understanding
Answer each question, then open the explanation.
1. What must you record before describing a displayed market observation?
Show answer and why
Answer: The instrument or universe, timeframe, timestamp and measure.
Why: Those details establish what the observation actually describes.
2. Does a past observation establish the next market movement?
Show answer and why
Answer: No. It describes observed data, rather than a guaranteed future result.
Why: An interpretation can be wrong even when the historical data is correct.
3. Why check the data source and delay?
Show answer and why
Answer: To understand when and how the measure was recorded.
Why: A stale, simulated or differently defined observation may not support the comparison you intend.
Key takeaways
- Breadth measures how many stocks are participating in a move, not just the index average.
- Broad and narrow heatmaps describe participation; neither reliably identifies a market top.
- The dashboard combines macro tape including SPY, QQQ, DIA and the US dollar proxy UUP with US and global sector heatmaps.
- A green US heatmap and red global heatmap show different regional moves; investigate the period and markets shown.
- Breadth signals are context, not timing. Use them with fundamentals and your own thesis.
