HOW TO READ THE CHART
A fair comparison starts with a clear definition.
Gold uses the COMEX continuous gold-futures reference series, Bitcoin uses BTC/USD, and equities use the S&P 500 price index. The S&P 500 line excludes dividends, so it is not a total-return measure. Raw values remain visible in the chart details while the lines show indexed performance.
Optional comparisons include COMEX continuous silver futures, Ethereum in U.S. dollars, the Nasdaq-100 price index, the U.S. Dollar Index and continuous WTI crude futures. The dollar index is a macro benchmark rather than an investment asset. Continuous futures can be affected by contract rolls.
Bitcoin trades continuously. Gold futures and the S&P 500 follow their own market schedules, so their latest timestamps and observation gaps can differ. On long ranges, each line begins only when that series has data; earlier Bitcoin history is never invented.
The one-week view uses one shared seven-calendar-day window. Exchange-traded lines pause across closures instead of drawing a move through hours when that market was not trading.
