Methodology#

The roster and weights come from SPY holdings disclosed to the SEC on Form N-PORT, a public filing. We roll the filed weights forward using each member's subsequent price change and combine multiple share classes of the same company into one row. Return periods other than 1 day use adjusted closes, which treat dividends as reinvested. See the full constituents and weights, the S&P 500 index YTD return, or scan the S&P 500 heatmap.
