S&P 500 comparison
The same dollars, on the same days, in the S&P 500 — and a time-weighted return to compare fairly.
- Same dollars, same days. Every purchase also “buys” SPY at that day's close; every sale “sells” the same dollar amount. No guesswork about start dates.
- Dividends on both sides. The index uses SPY's adjusted close, so reinvested dividends count. Your own dividends count too.
- Every holding against the index. A bar for each stock shows how many percentage points it is ahead of or behind the S&P 500 since you bought it.
