Common questions
What makes QQQ different from SPY in a calculator?
QQQ is more concentrated and growth-oriented, which can create larger swings in historical outcomes and makes the chosen start date especially important.
Should a QQQ calculator use adjusted close prices?
Yes. Adjusted close is the cleaner choice for long-term backtests because it accounts for events that would otherwise distort historical results.
Can I compare monthly and yearly investing?
That is the recommended product direction. The form is already structured around frequency inputs so both schedules can be supported cleanly.
