Max DD

Largest decline from a market peak during the calendar year.

Percentile

Where the observation ranks against the index’s full history.

YTD return

Index price return for the year, shown alongside the drawdown.

Method

Every row — including the current year — is the index itself (S&P 500, Nasdaq Composite, Dow Jones), measured close to close from the year’s first close. Drawdowns are close-based, so they read shallower than an intraday figure: March 2020 is −33.9% here against roughly −35.4% intraday. Returns exclude dividends.

Historical comparison

Annual market stress

More severe drawdowns appear warmer; positive returns appear green.
