Metric basis
Period changes and the 52-week range are provider values, not dividend-reinvested total returns or official index returns. Long-horizon colors use 10 percentage-point steps, saturating at the extremes. P/E uses trailing 12-month earnings. Growth is 3-year CAGR, not year-on-year growth. Dividend and financial periods can differ from the closing date. Missing, inapplicable and nonpositive P/E or P/B values are withheld. The provider update is not a fiscal period end.

Do more advancing stocks mean a rising index?
Advancing share among stocks with a daily change: 245 / 503 (48.7%). Missing daily changes / all constituents: 0 / 503. Unchanged stocks stay in the denominator; missing changes do not. Each stock has one vote, unlike an index that gives larger companies more weight. This summary always uses daily changes for the full membership, independently of the sector filter and map horizon.
A hypothetical three-stock example: starting weights of 80%, 10% and 10%, with returns of +10%, −2% and −2%, produce a weighted return of +7.6% (0.8 × 10 − 0.1 × 2 − 0.1 × 2), although only one stock in three advances. This is not an observed index result. Map areas must not be used to calculate an official index return.
Try it: compare the colors of the largest tiles with the rest of the map, then select a sector to see where the moves are concentrated. The advancing share does not predict the next session.

How to read this heatmap
Area represents reported company market capitalization; color and height represent the change from the previous closing session. Areas are not official index weights. Multiple share classes may share the same company market cap. The map uses current membership, not historical index constituents.
Turn the numbers into a question about your life
After exploring the market, compare your own assumptions. Amounts and tax rates below are hypothetical illustrations, not observed salaries, quotes or statutory rates.
Does a $500 pay rise leave more to save?
If monthly take-home pay rises from $3,000 to $3,500 but housing rises from $1,000 to $1,600, you have $100 less left each month when other costs stay the same. All amounts are USD. Compare your current budget with a new job or home.
Include transport and irregular annual bills as well as housing. The comparison also shows the take-home pay needed to leave the same amount as your current plan.
Does the same dividend yield mean the same income?
A $50 share paying $2 annually has a 4% gross yield. With 100 shares, annual gross dividends are $200, but a hypothetical 20% deduction leaves $160: $40 less than a zero-deduction scenario. All amounts are USD.
Try 100 shares, $2 annual dividend per share, and tax rates of 0% and 20% in the calculator. Check actual taxes, fees and exchange rates separately; dividends can change.
Does twice the minimum wage mean twice the living standard?
Converting wages to dollars can change rankings as exchange rates move. A regional legal floor and a nationwide statistic may not describe comparable workers.
First compare source years, coverage and hourly conversion methods in the wage atlas. Then use actual take-home income and living costs to compare budgets.

About the data
Constituents come from the Wikipedia-based DataHub dataset. Tickerbot is the primary source of closes and market caps, supplemented by TGMCharts. Only dated daily closes are accepted; changes use the provider reference for the previous session. Capitalization and fundamentals follow their own provider refresh schedules. Collection outages retain the last validated snapshot. Map areas use reported company capitalization and can differ from official index weights. Sentiment has separate sources and observation dates.
