Frequently asked questions

What is historical return analysis?
It uses past price data to illustrate how an asset performed over a chosen window. Results are educational—not predictions of future performance.
Why compare nominal vs real returns?
Nominal returns ignore inflation; real returns adjust for purchasing power. Both are useful, but they answer different questions.
Does past performance predict the future?
No. Historical results can inform context, but past performance does not guarantee future results.
