One-year performance is the trailing annual return — long enough to reveal durable trends, short enough to stay relevant. This heatmap colors US stocks by 1-year return, sized by market cap and grouped by sector.
Greener tiles beat the market over the trailing year, redder tiles trail it.
YTD anchors to January 1st; the 1-year view is a rolling twelve months. Mid-year they can disagree sharply — a stock that crashed in December can be YTD-green but 1-year-red.
Historically the strongest documented factor — but it reverses violently at crashes. It describes where money has been, not where it must go.
It answers "who has actually been compounding" — the multi-year winners tend to stay green here long before they make headlines.
